Scope Definition — Market Boundary Setting

Before any data collection begins, the research scope is formally defined in writing: which cell chemistries are in scope, which application segments, which geographies, which value chain nodes (materials, manufacturing, end-use, recycling), and which adjacent markets are explicitly excluded. Scope definition is reviewed by a second analyst before fieldwork begins. For battery markets, scope is particularly critical because overlapping market definitions — for example the boundary between the EV battery market and the battery cell manufacturing market — create double-counting risk that invalidates market size estimates if not carefully managed. Every Faradex report contains an explicit Scope of Research section stating both what is included and what is not.

Primary Fieldwork — Direct Panel Conversations

The primary research layer consists of structured 45–60 minute conversations with practitioners who have direct operational exposure to the specific market segment being researched. For battery markets this means cell process engineers, OEM battery procurement executives, cathode and anode materials scientists, gigafactory project developers, battery recycling operators, and energy storage system integrators — not generic energy consultants. All sessions are conducted directly by Faradex analysts. Expert network platforms are used only for introductions. Panel composition must meet the 2×2 supply/demand and geographic grid standard described in Section 4.

Secondary Research — Approved Sources Only

Secondary research draws exclusively from the approved source categories defined in Section 2. For battery markets this means company annual reports and earnings transcripts, US DOE and IEA publications, EU Commission regulatory documents, USGS mineral statistics, patent filings from EPO, USPTO, and CNIPA, trade body publications from RECHARGE and NAATBatt, Benchmark Minerals Intelligence raw material pricing data, and verified specialist press. Secondary findings are used to corroborate, contextualise, and calibrate primary panel findings. They are never used as the sole basis for a market size estimate.

Cross-Reference & Validation — No Single-Source Claims

Every data point that appears in a published Faradex output must be corroborated by at least one additional source beyond its origin — a second primary panellist with independent knowledge, or a second approved secondary source. Where corroboration is not available, data is either excluded or presented as a Faradex analyst estimate with the estimation basis explicitly stated. This rule prevents the circular amplification problem where a single unverified claim becomes a market finding through repetition. Market size numbers that cannot be independently corroborated are never stated as fact.

Analyst Review — Adversarial Challenge Before Publication

All outputs are reviewed by a second Faradex analyst before publication. The review is not copy-editing — it is an adversarial challenge to every quantitative and analytical claim in the document. The reviewing analyst attempts to identify unsupported claims, inconsistencies between sections, circular logic, and gaps in the evidence base. Reports that do not clear the review threshold are returned for revision and re-review, not published with caveats. Publication date is secondary to research integrity.

Source Integrity Rule — No Exceptions

If a number in a Faradex output cannot be traced to an approved source above, it is either presented as a Faradex analyst estimate with the estimation basis explicitly stated, or it is not included. Faradex does not use circular citations — citing Source A which cites Source B which cites Source A — as data validation. Every citation chain must terminate at a primary event: a production volume in a filing, a shipment figure in an earnings call, a regulatory document, a patent record, or a verified primary panel conversation. The word "primary" in "primary sources" means exactly that.

Primary Research

Primary Panel Standards — Battery Sector Specific

Primary panel conversations are the core of what differentiates Faradex from desk-research operations. These are the standards every primary engagement is held to — without exception and without waiver.

All fieldwork conducted directly by Faradex analysts — never outsourced

Expert networks are used solely for introductions and panellist access. They do not conduct interviews, formulate questions, interpret findings, or contribute to report content in any form. Every primary data point attributed to Faradex primary research was collected in a session personally conducted by a named Faradex analyst. This is explicitly not the standard practice in the market research industry. Most syndicated publishers outsource primary collection to junior researchers or third-party interview services. Faradex does not.

Panel composition: 2×2 supply-demand / geographic grid — minimum standard

For every battery market research engagement, the panel must represent both supply-side (cell manufacturers, material producers, equipment and tooling suppliers, recyclers) and demand-side (OEM procurement executives, energy storage developers, project finance investors, fleet operators) perspectives, across at least two distinct geographic regions. A panel drawn entirely from Chinese supply-side sources for a global LFP market report is not acceptable regardless of how well-placed those sources are. A panel of South Korean engineers for a solid-state report that covers Toyota's programme is structurally incomplete. Single-geography panels are rejected before fieldwork begins.

Battery-specific panellist qualification criteria by chemistry

For chemistry-specific reports, panellists must have direct operational exposure to the specific chemistry or application being researched — not general battery industry experience. For a solid-state battery report: qualified panellists include cell process engineers with direct experience on sulfide or oxide electrolyte pilot lines; OEM procurement executives who have run qualification audits on solid-state cell candidates; materials scientists with published research or granted patents in solid electrolyte chemistry; and gigafactory project developers who have evaluated dry room infrastructure requirements for solid-state manufacturing. Generic battery industry analysts or technology commentators without this direct exposure do not qualify as primary panellists for chemistry-specific reports.

Panellists share professional opinion — not confidential information

Every panellist is explicitly briefed before engagement: they are asked to share professional judgments and observations based on their general industry experience only. They are explicitly instructed not to disclose anything covered by a current or former employer NDA, employment contract, or confidentiality undertaking of any kind. Sessions are terminated if a panellist volunteers information that appears to cross this boundary. Faradex does not prompt for, accept, or use material non-public information, confidential business information, or trade secrets. This is not a compliance position. It is an editorial standard enforced at every stage of every engagement without exception.

All panellist identities permanently anonymised

No panellist is identified by name, company, job title, or any combination of details that would allow identification in any Faradex published output. Source attribution is retained internally by the researching analyst. Client organisations purchasing Faradex reports do not receive source attribution data, are not entitled to request it, and are not provided any information that would allow inference of panellist identity. Panel participants engage with the explicit understanding that their contributions are anonymised and that no identifying details are disclosed to any third party, including the commissioning client.

Primary findings corroborated before publication — no single-source findings

No finding from a primary panel conversation is published as a market finding without corroboration from at least one additional independent source — a second primary panellist with independent knowledge of the same fact, or a verifiable approved secondary source. Where a primary finding cannot be corroborated, it is either excluded from the published output or presented as an analyst estimate or single-source observation with the caveat clearly stated. This rule prevents the circular amplification problem: a single unverified claim from one panellist becoming a "primary research finding" through publication. It also prevents panellist bias — one person's strongly held view being presented as market consensus.

Absolute Boundary — Insider Information

Faradex does not solicit, receive, incorporate, or publish material non-public information, confidential business information, or trade secrets of any description. This boundary applies regardless of how a request is framed, who requests it, or what a client states their intended use is. Competitive intelligence profiles produced by Faradex are built exclusively from public filings, patent databases, verified press, conference proceedings, and voluntary panel opinions. Clients commissioning intelligence profiles should not expect, and will not receive, information obtained in breach of any confidentiality obligation.

Market Estimation

How Faradex Sizes Battery Markets

Battery market sizing is more technically complex than most sectors because the same battery cell appears in multiple market estimates at different value chain levels. Faradex applies a consistent bottom-up methodology with explicit scope boundary rules designed to prevent the double-counting that inflates most published battery market estimates.

2025

Universal Base Year

All Faradex market size estimates use 2025 as the base year across all 100+ titles. Base year estimates are anchored to company production disclosures, IEA battery demand data, USGS mineral production statistics, and primary panel calibration. The 2025 base is current enough to incorporate the Q1 2026 Strait of Hormuz supply chain disruption where relevant to specific markets.

2026–35

Forecast Period

Forecast period across all titles. 10-year horizon matches battery sector planning cycles — OEM platform development, gigafactory investment, and raw material contract terms all operate on this timeframe. CAGR is expressed to one decimal place, calculated from 2026 to 2035 using 2025 as the compound anchor. No rounding to whole numbers.

USD

Currency & Unit Rules

All values in USD. Below USD 1 billion: expressed in Million with one decimal (e.g. USD 892.5 Million). At or above USD 1 billion: expressed in Billion with two decimals (e.g. USD 8.14 Billion). A report that opens in Billion never shifts to Million for the forecast year. GWh figures to 0.1 GWh precision for capacity data.

Bottom-Up Estimation by Value Chain Layer

Faradex builds battery market size estimates bottom-up from production capacity data, shipped GWh volumes, average selling price per kWh, and verified end-use demand data — not from top-down GDP multiples or general energy transition macro indices. Estimation approach varies by market layer:

Cell-Level Markets (LFP, NMC, Sodium-Ion, Solid-State etc.)

Base year estimate = disclosed shipped GWh × ASP per kWh at cell level. Shipped GWh anchored to company earnings disclosures and IEA Global EV Outlook data. ASP per kWh from Benchmark Minerals Intelligence pack cost index (adjusted to cell level) and OEM supplier contract price ranges from verified trade press. Forecast driven by demand scenario modelling with IEA Stated Policies Scenario (STEPS) as the base case demand anchor, calibrated against primary panel views on chemistry substitution rates. Cell-level estimates cover cell value only — not pack, module, or system value. This boundary is stated explicitly in every report scope section and coordinated with adjacent pack-level and system-level titles in the Faradex Sectors.

Materials Markets (Cathode, Anode, Electrolyte, Separator, PVDF)

Base year = verified production volume in tonnes × market price per tonne. Production volume from USGS Mineral Commodity Summaries, company production disclosures, and trade body data. Pricing from Benchmark Minerals Intelligence spot price data and verified trade press contract price ranges. Materials market estimates explicitly exclude downstream value-added — a cathode active materials (CAM) market estimate covers CAM value only, not the value of cells made from those materials. This is the single most important rule in battery materials market sizing: the CAM value, the precursor value, and the cell value are three separate non-overlapping market sizes. Faradex titles in each layer are scoped to be non-overlapping.

System-Level Markets (BESS, EV Battery Packs, BMS, On-Board Chargers)

Base year = units or GWh deployed × system-level selling price. System price includes cell cost plus BMS electronics, thermal management system, structural components, enclosure, assembly labour, quality certification, and warranty reserve. System price derived from OEM supplier tender data (verified trade press), company earnings disclosures for integrated manufacturers, and primary panel estimates from procurement executives with direct system supply agreement experience. System-level estimates include all value-added above the cell. Scope statements confirm this boundary to prevent conflation with cell-level estimates from the same Sectors.

End-of-Life Markets (Recycling, Black Mass Processing, Second-Life BESS)

Base year = end-of-life battery volumes reaching processing (tonnes of black mass equivalent) × processing and material recovery revenue per tonne. End-of-life volumes anchored to battery deployment data from 8–12 years prior adjusted for early retirement, accident loss, and warranty failure rates derived from OEM recall data and industry loss rate studies. Recycling market estimates cover hydrometallurgical, pyrometallurgical, and direct recycling revenue separately. Scope statements explicitly distinguish between battery collection market size and material recovery market size — a distinction many publishers fail to make, resulting in estimates that double-count the same battery mass twice.

Double-Counting Prevention — The Critical Rule

The same GWh of LFP cells appears in the LFP battery market, the EV battery market, the lithium-ion battery market, the battery pack assembly market, and the BESS market — depending on how each is scoped. Faradex manages this with explicit scope boundary statements in every report defining: (1) which value chain nodes are in scope, (2) whether revenue is counted at cell, module, pack, or system level, (3) which end-use applications contribute to the estimate, and (4) which adjacent Faradex titles cover the non-included portions of the value chain. Buyers should not aggregate Faradex title estimates without checking scope boundary alignment.

Geopolitical Context

Mandatory Geopolitical Context — Battery Supply Chain Specific

Battery supply chains are among the most geopolitically exposed of any industrial sector. Faradex incorporates specific geopolitical context where it has a verified, material effect on the specific market being covered. It is never used as generic background.

Strait of Hormuz Disruption — Q1 2026

The IMF-confirmed Strait of Hormuz disruption in Q1 2026, resulting from the US-Iran conflict, affected approximately 20% of global seaborne LNG. This had verified supply chain implications for battery sector participants in South Korea and Japan, where LNG-dependent petrochemical facilities produce electrolyte solvent precursors (ethylene carbonate, dimethyl carbonate) and PVDF binder feedstocks. Secondary effects were identified in the Netherlands and Belgium, where polymer electrolyte composite manufacturers use Middle Eastern refinery-sourced fluoropolymer feedstocks.

Rule for inclusion: geopolitical context is incorporated in Faradex regional analysis only where the disruption has a verified, material, and specific effect on the supply chain, raw material cost structure, or production capacity of the specific market being covered. It is not included as background colour.

IRA Foreign Entity of Concern (FEOC) Rules

US Inflation Reduction Act Section 30D clean vehicle credit restrictions classify Chinese battery manufacturers (CATL, BYD, CALB, Gotion, EVE) as Foreign Entities of Concern from 2024. This materially affects North American supply chain strategy for every OEM seeking IRA-eligible battery supply. Faradex incorporates FEOC compliance implications in all North America regional sections and all US-market battery demand analysis. The USD 35/kWh Advanced Manufacturing Production Credit (AMPC) for domestically produced cells is modelled in US gigafactory economics analysis.

Standards & Limits

What Faradex Does Not Do

As important as what is included is what is explicitly prohibited. These are not aspirational standards. They are enforced at the analyst review stage as binary pass/fail criteria.

✗

Circular citations. Faradex never cites Source A which cites Source B which cites Source A. Every citation chain terminates at a primary event — a filing, a regulatory document, a patent, or a verified primary panel conversation. A market size cited from a news article citing a research report citing an industry estimate is not a source.

✗

Value chain aggregation as market size. Faradex never sums cell value + pack value + system value to produce a larger "battery market" estimate. Each layer is sized separately. The LFP cell market, the LFP battery pack market, and the LFP BESS market are three distinct estimates, not one additive total.

✗

Unattributed CAGR claims. Faradex never states a market will "grow at X% CAGR" without the demand and pricing assumptions being traceable within the report. CAGR is an output of the estimation model, not an input. A CAGR figure without the underlying GWh demand build or ASP trajectory is not a market forecast.

✗

Market share percentages without derivable data. Company market share percentages are only stated where they are derivable from disclosed production or shipment volumes. Competitive landscape sections describe competitive dynamics, cost positions, and strategic priorities — not fabricated share percentages.

✗

Geopolitical filler. References to the Hormuz disruption, FEOC rules, or EU Battery Regulation appear only in sections where they have a specific, verified effect on the market being analysed. They are never inserted as generic "market environment" padding.

✗

AI-generated prose without specific data. Every paragraph in a Faradex report contains at least one specific, verifiable fact — a production figure, a named company and action, a regulatory provision, a patent filing date, or a price datum. Paragraphs consisting entirely of general statements about market trends are rejected at analyst review.

✗

Insider or confidential information. No Faradex output incorporates information obtained in breach of any confidentiality obligation — yield rate data from active employees, unpublished capacity data from company insiders, or pricing data from undisclosed supply contracts. This applies to competitive intelligence profiles as well as market reports.

✗

Double-counting across adjacent titles. Where Faradex covers both the LFP Battery Market and the EV Battery Pack Market, the value in each is explicitly non-overlapping. Scope boundaries are coordinated across titles. A buyer aggregating multiple Faradex titles should not be double-counting the same underlying battery value.
