The battery technology industry is witnessing unprecedented change catalyzed by electric vehicle penetration and energy storage needs. The battery cell market will expand, on average, by over 20% annually through 2030 to at least $360 billion worldwide with potential acceleration to $410 billion. Growth in Li-ion battery sales in the coming decade will continue at a compound annual rate of about 30%, driven by EVs and energy storage systems to 4,000-4,500 gigawatt-hours by 2030. Lithium-ion technology leads existing market applications as other chemistries develop for niche uses.

Stationary battery storage is a key area of growth, with market estimates to reach USD 4.14 trillion by 2034. Next-generation battery technologies offer outstanding growth prospects in specialized uses. The size of the energy storage sodium ion battery market exceeded USD 245.3 million in 2024 and is anticipated to witness growth at a CAGR of 25.3% during the period of 2025-2034, spurred by increasing demand for safer, thermally stable batteries minimizing fire and explosion hazards in energy storage systems.

As penetration of electric vehicles increases, there may be a market for second life batteries with new interfaces to the power industry with significant ramifications for stationary storage. Developments in solid state batteries, applications of graphene in batteries, and optimization of battery packs continue to progress through automotive start-stop applications, SLI batteries, traction batteries, and reuse of EV batteries, while conventional alkaline and lead acid technologies remain current in certain segments of the market.
