China's power and energy storage battery sector delivered robust year-on-year growth in January 2026, with combined production reaching 168.0 GWh, up 55.9% from the prior year, according to industry data. Total sales climbed 85.1% annually to 148.8 GWh, though declining 25.4% month-on-month, reflecting typical seasonal patterns following the year-end rush. The figures underscore strengthening demand for battery capacity even as domestic electric vehicle installations showed more modest gains, pointing to a two-month lag between production and final deployment.

Energy storage batteries emerged as a standout driver, with output soaring 164% year-on-year to 46.1 GWh and capturing 31% of total production. Power batteries accounted for 102.7 GWh, representing 69% of the mix and growing 63.2% annually despite a 28.6% monthly decline. The surge in storage capacity marks a significant shift in industry dynamics, establishing energy storage as a critical secondary growth pillar alongside automotive applications.

Domestic vehicle installations rose a modest 8.4% year-on-year to 42.0 GWh, down 57.2% from December, aligning with typical post-holiday demand normalization in China's auto market. Exports totaled 24.1 GWh, comprising 16.2% of monthly sales, with power battery shipments advancing 59.3% to 17.7 GWh while storage exports remained flat at 6.4 GWh.

The divergence between surging production and moderate domestic installations suggests substantial battery output is supporting export vehicle manufacturing, with typical deployment lags of approximately two months between battery sales and final vehicle installations.

Storage Batteries Drive Production Gains

The 164% annual surge in energy storage battery production signals accelerating adoption of grid-scale and commercial storage systems. Storage batteries reached 46.1 GWh in January, capturing nearly one-third of total output compared to minimal shares in previous years. This expansion reflects China's push to integrate renewable energy sources and stabilize grid infrastructure, creating sustained demand parallel to automotive applications.

Power battery production maintained strong momentum at 102.7 GWh, up 63.2% year-on-year, though the 28.6% monthly decline from December reflected normal seasonal adjustments. Combined sales of 148.8 GWh represented an 85.1% annual increase, outpacing production growth and suggesting inventory drawdowns or accelerated shipments to meet downstream demand.

Lithium Iron Phosphate Dominates Installations

Domestic vehicle installations in January totaled 42.0 GWh, with lithium iron phosphate (LFP) batteries commanding 77.7% market share at 32.7 GWh. Ternary lithium batteries captured the remaining 22.3% with 9.4 GWh, reinforcing LFP's cost advantage and safety profile for mainstream electric vehicles.

By vehicle segment, pure electric passenger cars accounted for 60.3% of installations at approximately 25 GWh, declining 1.4% year-on-year. Plug-in hybrid passenger vehicles represented 22.2% with 9.3 GWh, advancing 22.1% annually as automakers expand hybrid offerings. Pure electric commercial vehicles comprised 15.2% of installations, surging 41.9% year-on-year before moderating from December's elevated levels.

The 57.2% month-on-month decline in total installations reflected typical seasonality following strong year-end deliveries, with commercial vehicle demand particularly volatile after the previous month's spike.

Market Leaders Maintain Positions

Contemporary Amperex Technology(CATL) retained its dominant position with 20.91 GWh installed in January, deploying 7.65 GWh of ternary batteries and 13.26 GWh of LFP across both chemistries. Pure electric passenger vehicles accounted for 13.73 GWh of CATL's installations, demonstrating strong positioning in mainstream EV segments.

BYD installed 7.32 GWh entirely in LFP chemistry, with 6.72 GWh serving passenger vehicles split between 4.10 GWh for pure electric models and 2.61 GWh for plug-in hybrids, closely matching its vertically integrated vehicle production mix.

Gotion High-Tech, CALB Group, and EVE Energy formed a closely matched second tier with installations of 2.55 GWh, 2.22 GWh, and 2.07 GWh respectively. Gotion focused primarily on LFP with 0.95 GWh in commercial vehicles, while CIAT balanced ternary and LFP chemistries with notable plug-in hybrid exposure. EVE Energy deployed 1.33 GWh to commercial vehicles, establishing a distinctive niche in that segment.

Svolt Energy Technology installed 0.71 GWh of ternary and 0.35 GWh of LFP batteries, primarily serving premium passenger vehicles aligned with parent Great Wall Motor's product strategy. Sunwoda Electronic and Rept Battero Energy targeted mainstream passenger car markets with their deployments.

Export Demand Supports Production Levels

January's 24.1 GWh in battery exports represented 16.2% of total monthly sales, with power battery shipments climbing 59.3% year-on-year to 17.7 GWh. Storage battery exports held steady at 6.4 GWh. The robust export growth in power batteries aligns with Chinese automakers' expanding overseas vehicle production and sales, requiring battery supply chains to support manufacturing in international markets.

The substantial gap between production volumes and domestic installations indicates significant battery output is channeled toward export vehicles, with typical two-month lags between battery manufacturing and final vehicle assembly creating temporal disconnects in monthly data. This export orientation supports elevated production levels despite more moderate growth in domestic vehicle installations, reflecting Chinese battery makers' increasing integration into global automotive supply chains.
