Segmentation Analysis

Analysis by Vehicle Type

The passenger cars segment held the largest market share in 2025 because of the rising demand from private buyers seeking longer single-charge range, shorter charging stops, and improved crash safety in everyday vehicles. California’s Advanced Clean Cars II rule, phases new passenger-car sales toward 100% zero-emission by 2035, and the United Kingdom’s zero-emission vehicle (ZEV) mandate for cars push automakers to upgrade passenger battery technology. Purchase schemes like United States clean vehicle tax credit under Section 30D and France’s bonus ecologique lower the effective price of advanced battery cars and pull demand forward.

 

The commercial vehicles segment will grow at the fastest CAGR during the forecast period because of the lower total cost of ownership, less charging downtime, and high daily asset utilisation. Rising demand from rapid electrification of last-mile delivery, urban logistics, and regional freight as e-commerce volumes rise. California’s Advanced Clean Trucks rule and the European Union’s heavy-duty vehicle CO2 standards require manufacturers to electrify commercial fleets, accelerating adoption.

Analysis by Anode Material

The lithium-metal segment held the largest market share in 2025 because it deliver the maximum theoretical capacity and energy density and are the central reason to adopt solid-state cells in the first place. Demand is driven by premium long-range vehicle programmes that need the highest possible energy per kilogram. The United States Advanced Manufacturing Production Credit under Section 45X and Bipartisan Infrastructure Law battery-manufacturing grants underwrite domestic lithium-metal cell production. Anode-free designs and the ability of solid electrolytes to suppress lithium dendrites improve both cost and safety. The European Union’s Critical Raw Materials Act, which secures lithium supply, and Australia’s critical-minerals and lithium development programmes reduce material and feedstock risk for producers. Concentrated intellectual property among leading developers further consolidates the segment.

 

The silicon-composite segment will grow at the fastest CAGR during the forecast period because silicon-rich anodes provide high capacity while remaining largely compatible with existing electrode lines, offering a faster and cheaper route to market than pure lithium-metal. Demand is driven by developers balancing energy density against near-term manufacturability, often through semi-solid designs. South Korea’s strategic-technology investment tax credit under the K-Chips Act and the United Kingdom’s Automotive Transformation Fund back silicon anode research and pilot production. Abundant silicon feedstock and progress in prelithiation and binder technology improve cycle life. Chinese industrial guidance funds directed at advanced anode materials accelerate domestic capacity. A favourable cost-per-kilowatt-hour profile and ease of scaling reinforce its rapid growth.

 

Anode material categories include:

•      Lithium-Metal (Largest Category)

•      Silicon-Composite (Fastest-Growing Category)

Analysis by Battery Capacity

The 20 to 100 Ah segment held the largest market share in 2025 because this capacity band matches the cells used in most mainstream passenger battery packs and benefits from standardised module formats and economies of scale. Demand is driven by the bulk of passenger electric-vehicle programmes that target this energy range. The European Union’s digital battery passport under the Batteries Regulation and China’s national GB battery standards encourage standardised, traceable cells in this band. Cell-to-pack designs and straightforward thermal management make this capacity the easiest to integrate at volume. Indonesia’s battery and nickel downstreaming programme expands upstream cell-material supply for these formats. A practical balance between energy content and manufacturability keeps this band dominant.

 

The above 100 Ah segment will grow at the fastest CAGR during the forecast period because larger cells cut part count, cost, and pack complexity, which suits long-range premium vehicles and heavier commercial applications. Demand is driven by buyers and operators seeking extended range and by duty cycles that need large energy reserves. India’s production-linked incentive (PLI) scheme for Advanced Chemistry Cell (ACC) battery storage supports large-format cell production. Fewer cells per pack also lower assembly and wiring overheads. China’s power-battery recycling and echelon-use regulations encourage high-capacity formats with end-of-life recovery built in. Growing demand for high-energy reserves in towing, fleet, and premium use cases drives the fastest expansion.

 

Battery capacity categories include:

•      Below 20 Ah

•      20 to 100 Ah (Largest Category)

•      Above 100 Ah (Fastest-Growing Category)
