Secondary battery market seen nearly doubling by 2035

The secondary battery market is projected to grow from $143.8 billion in 2026 to $294.8 billion by 2035, driven by electric vehicles, grid storage and consumer electronics. Asia-Pacific leads the market as battery makers expand capacity, invest in new chemistries and respond to rising demand for rechargeable power storage.

Why it matters: - Secondary batteries sit at the center of the energy transition because they power electric vehicles, grid storage, consumer devices and backup systems. - Each battery electric vehicle requires 50–100 kWh of cell capacity, so EV unit growth creates direct demand for battery output measured in GWh. - The market's projected climb to $294.8 billion by 2035 signals sustained demand for rechargeable storage across transportation and power systems.

What happened: - The secondary battery market was estimated at $132.8 billion in 2025. - The market is forecast to rise to $143.8 billion in 2026 and then reach $294.8 billion by 2035. - The forecast implies an 8.3% compound annual growth rate for 2026 through 2035. - The report covers rechargeable batteries, also called accumulators, across major chemistries and applications.

The details: - Lithium-ion batteries dominate the market because of high energy density, long cycle life and falling costs. - Other chemistries in the market include lead-acid, nickel-cadmium, nickel-metal hydride, sodium-sulfur, solid-state and sodium-ion. - Electric vehicles are the largest and fastest-growing application segment. - Consumer electronics, grid energy storage, industrial uses and backup power systems remain key demand pools. - By capacity, the market spans below 100 Ah, 100–500 Ah and above 500 Ah segments. - Asia-Pacific is the largest and fastest-growing regional market. - North America, Europe, Latin America, and the Middle East and Africa also contribute to demand growth. - A sample report is available for more market detail. - The full report is also available for purchase.

Between the lines: - EV adoption is the clearest demand engine because battery demand scales directly with vehicle production. - Renewable energy deployment is also boosting demand by increasing the need for utility-scale storage to balance intermittency. - Industry momentum is shifting toward LFP batteries, battery recycling and vertical integration as manufacturers look to lower costs and secure materials. - New technology work on silicon anodes, high-nickel cathodes, advanced electrolytes and dry electrode manufacturing is aimed at improving performance and reducing production costs. - Policy support is reinforcing growth through EV incentives, emissions rules, storage mandates and recycling requirements.

What's next: - Battery makers are expected to keep expanding manufacturing capacity to meet EV and storage demand. - Solid-state batteries, lithium-sulfur batteries and sodium-ion batteries are positioned as next-generation opportunities. - Recycling, critical-material recovery and second-life applications are likely to become more important as supply chains mature. - Asia-Pacific is expected to remain the key growth center, with China, Japan, South Korea and India driving production and adoption. - North America and Europe are likely to keep investing in domestic manufacturing, recycling and supply-chain security.

The bottom line: - Secondary batteries are moving from a niche component to core infrastructure for mobility and clean power, and the market still has years of growth ahead.
