Nickel Metal Hydride (NiMH) Battery Market, By Type, By Application, By Region
Market Synopsis
The global nickel metal hydride battery market size was USD 3.40 Billion in 2025 and is expected to register a revenue CAGR of 6.9% during the forecast period. Market revenue growth is supported by continued record hybrid electric vehicle demand, with Toyota selling 4.4 million hybrid vehicles globally in 2025, more than any other automaker, and hybrids accounting for nearly 40% of Toyota's global sales in fiscal year 2025. Toyota Battery Co., formerly known as Primearth EV Energy (PEVE) and renamed effective October 1, 2024 following Toyota's March 2024 buyout of Panasonic's remaining stake, remains the world's largest disclosed dedicated hybrid battery manufacturer, producing prismatic nickel metal hydride and lithium-ion battery packs at its Kosai, Shizuoka and Taiwa, Miyagi facilities in Japan. These are some of the key factors driving revenue growth of the market.
Prismatic nickel metal hydride battery manufacturers, cylindrical and AA/AAA-format rechargeable nickel metal hydride cell manufacturers, and bipolar nickel metal hydride developers are the commercial categories that constitute the nickel metal hydride battery market, with hybrid electric vehicle powertrains the dominant demand source ahead of consumer rechargeable batteries and industrial and medical applications. For instance, in August 2026, Toyota announced plans to roll out next-generation hybrid batteries beginning in 2027, targeting 5 million hybrid sales in a single year and converting Japanese battery production lines serving approximately 600,000 vehicles to the new pack design, though the company did not disclose the chemistry of the next-generation battery, leaving open whether it will be an improved nickel metal hydride design, a lithium-ion pack, or another chemistry entirely.
However, Toyota, the market's largest single demand source, has been progressively shifting its highest-volume nameplates toward lithium-ion battery packs, with lithium-ion already equipping the Prius, Corolla, Corolla Cross, and higher trim levels of the RAV4 in key markets, even as the company states that bipolar nickel metal hydride remains its preferred choice for hybrid models sold in other markets. This chemistry bifurcation within a single automaker's own hybrid lineup, rather than a uniform industry-wide shift away from nickel metal hydride, creates genuine ambiguity about the technology's medium-term trajectory, and Toyota's undisclosed chemistry choice for its 2027 next-generation hybrid battery programme leaves the largest single swing factor in this market's forecast unresolved. These factors substantially limit nickel metal hydride battery market growth over the forecast period.
Segment Insights
Prismatic segment is expected to account for a significantly large revenue share in the global nickel metal hydride battery market during the forecast period
Based on type, the global nickel metal hydride battery market is segmented into prismatic, cylindrical and AA/AAA-format, and bipolar architectures. The prismatic segment commands the largest revenue share because Toyota Battery Co. and other hybrid powertrain suppliers manufacture the large majority of automotive nickel metal hydride packs in prismatic cell format, optimised for the specific voltage, packaging and thermal management requirements of hybrid electric vehicle battery packs, a format that has proven reliable enough that, according to industry sources, more than 16 million Toyota hybrids have been sold globally without a single battery-pack fire caused by thermal instability.
The bipolar segment is expected to register the fastest revenue growth rate in the global nickel metal hydride battery market over the forecast period, from a smaller base than conventional prismatic designs. Toyota has continued deploying bipolar nickel metal hydride architecture in select hybrid models as an alternative to lithium-ion, with the company describing bipolar nickel metal hydride as remaining the preferred choice in markets outside the United States even as its flagship US nameplates including the Prius and Corolla have moved to lithium-ion, reflecting bipolar NiMH's ability to narrow the power density gap with lithium-ion while retaining nickel metal hydride's non-flammable, dendrite-free safety profile.
Regional Insights
Cell Chemistry Asia Pacific — Largest Revenue Share, 2025
Based on regional analysis, the nickel metal hydride battery market in Asia Pacific accounted for the largest revenue share in 2025. Japan is the dominant country, hosting Toyota Battery Co., formerly Primearth EV Energy, at its Kosai, Shizuoka and Taiwa, Miyagi manufacturing facilities, which became a wholly owned Toyota subsidiary following the company's March 2024 buyout of Panasonic's remaining stake and subsequent renaming effective October 1, 2024. Toyota's global hybrid sales reached 4.4 million units in 2025, with the company's electrified vehicle mix, spanning hybrid, plug-in hybrid, battery-electric and fuel-cell models, expected to represent 56% of Toyota and Lexus worldwide sales in the current fiscal year on a target of nearly 6 million electrified unit sales. China and South Korea contribute secondary regional demand through consumer rechargeable nickel metal hydride cell manufacturing for AA and AAA formats used in cameras, toys and portable electronics.
Europe
The European nickel metal hydride battery market is expected to register moderate revenue growth over the forecast period, with regional demand driven primarily by Toyota and Lexus hybrid vehicle sales, which the company has confirmed reached all-time record levels across European markets. European nickel metal hydride demand continues to depend on Toyota Battery Co.'s Japan-based production rather than on domestic European nickel metal hydride cell manufacturing, leaving the region's hybrid vehicle supply chain reliant on the same Japanese facilities that serve global Toyota hybrid production, an exposure that would become more significant if Toyota's undisclosed next-generation hybrid battery chemistry shifts meaningfully away from nickel metal hydride.
North America
The North American nickel metal hydride battery market is expected to register moderate revenue growth over the forecast period, even as Toyota's highest-volume US nameplates increasingly shift to lithium-ion battery packs. Toyota and Lexus reported record US sales in 2025, with Toyota division electrified vehicle sales reaching 1,051,397 units, up 19.0% year on year and representing 49% of Toyota brand sales, though lithium-ion now equips the Prius, Corolla, Corolla Cross and higher RAV4 trim levels rather than nickel metal hydride. Other Toyota hybrid nameplates that achieved best-ever US sales years in 2025, including Camry Hybrid, 4Runner Hybrid and Tacoma, continue to rely on nickel metal hydride powertrains, sustaining regional demand even as the chemistry's addressable share of Toyota's total US hybrid lineup narrows over time.
Latin America
The nickel metal hydride battery market in Latin America is expected to register limited revenue growth from a low base, with regional demand met through hybrid vehicle imports from Toyota's Japanese and North American production network rather than through domestic nickel metal hydride cell manufacturing. No major regional manufacturing investment has been identified as of 2025, with growth expected to track broader hybrid vehicle adoption trends across Brazil and Mexico rather than any region-specific chemistry demand driver.
Middle East and Africa
The nickel metal hydride battery market in the Middle East and Africa is expected to register limited revenue growth from a low base, with regional demand met through hybrid vehicle imports rather than domestic nickel metal hydride cell manufacturing. No major regional manufacturing investment has been identified as of 2025, and growth is expected to track broader hybrid vehicle fleet adoption across Gulf and North African markets rather than any nickel metal hydride-specific demand driver.
