China EV Battery Installations Hit 2026 High in September

China EV Battery Installations Reach a September High

China EV battery installations reached 87.2 gigawatt-hours (GWh) in September 2026, setting a new monthly high for the year for the second consecutive month, according to data released Thursday by the China Automotive Battery Innovation Alliance (CABIA). Installations increased 14.7% year-over-year and 10.4% month-over-month, surpassing August's 79.0 GWh. Despite the continued increase in installed capacity, annual growth slowed to its lowest level since April, falling from 33.5% in July and 26.3% in August. Lithium iron phosphate (LFP) batteries remained the primary driver of the increase, reinforcing their dominant position in China's domestic electric vehicle battery market.

LFP Batteries Maintain Their Dominant Market Position

LFP battery installations totaled 74.5 GWh in September, increasing 19.9% year-over-year and 10.3% month-over-month to reach a new high for the year. These batteries represented 85.5% of total domestic installations, slightly below August's record share of 85.6%. The September figure ended a three-month run of consecutive record market shares but demonstrated that LFP technology continued to account for the overwhelming majority of installed battery capacity. Its contribution was central to the overall market increase, even as the industry's annual growth rate moderated. The data highlights the continuing importance of LFP batteries in China's vehicle electrification landscape.

Ternary Battery Installations Recover Month-Over-Month

Ternary battery installations reached 12.3 GWh in September, declining 10.9% year-over-year while increasing 11.7% from August. The month-over-month improvement ended three consecutive months of sequential declines. Ternary batteries accounted for 14.1% of total installations, up slightly from 14.0% in August but remaining below their share a year earlier. Although the monthly increase indicated an improvement from the previous month, the annual decline contrasted with the growth recorded by LFP batteries. The figures show that different battery chemistries continued to experience distinct demand patterns within China's broader battery market, with LFP technology retaining a substantially larger share of installations.

China's Battery Installations Increase During the First Nine Months

Domestic EV battery installations reached 576.3 GWh during the first nine months of 2026, an increase of 16.7% year-over-year. That growth rate was slightly below the 17.0% recorded during the first eight months, indicating a modest moderation in cumulative annual expansion. LFP installations totaled 477.2 GWh over the nine-month period, up 18.5% and representing 82.8% of the total. Ternary battery installations reached 97.9 GWh, increasing 7.3% and accounting for 17.0% of installations. These figures confirm that LFP batteries continued to outperform ternary batteries in both growth and market share, shaping the composition of China's installed EV battery capacity.

Commercial New Energy Vehicles Support Battery Demand

CABIA attributed growth in battery installations during the first three quarters to the expansion of commercial new energy vehicles (NEVs) and increasing battery capacity per NEV. Battery-electric trucks and special-purpose vehicles made significant contributions to the increase. This explanation indicates that battery demand was supported not only by the wider adoption of electrified vehicles but also by applications requiring substantial battery capacity. The source does not quantify the individual contribution of each commercial vehicle segment, so their precise shares of installation growth cannot be established from the available figures. Nevertheless, CABIA's assessment identifies commercial electrification and greater installed capacity per vehicle as important factors behind the cumulative increase in domestic battery installations.

Battery Production and Sales Continue to Expand

Combined production of power batteries and energy storage batteries reached 237.8 GWh in September, increasing 57.3% year-over-year and 0.3% month-over-month. Combined sales totaled 222.7 GWh, up 52.0% year-over-year but down 0.2% from August. CABIA reported that energy storage battery sales continued to grow significantly faster than power battery sales. Power battery sales reached 149.2 GWh, increasing 35.0% year-over-year, while energy storage battery sales rose 104.4% to 73.5 GWh. Energy storage batteries accounted for 33.0% of combined sales. The figures show that the battery industry's expansion extended beyond vehicle applications, with energy storage contributing a substantial share of sales growth.

Battery Exports Rise as Overseas Vehicle Production Expands

Combined exports of power and energy storage batteries reached 44.0 GWh in September, increasing 64.5% year-over-year and 3.7% month-over-month. Exports represented 19.7% of combined sales. Power battery exports totaled 28.4 GWh, up 60.9% year-over-year and 14.9% month-over-month. Energy storage battery exports reached 15.6 GWh, increasing 71.4% year-over-year but declining 11.9% from August. The contrasting monthly movements indicate that export performance differed between the two battery categories, even as both recorded strong annual growth. Overall, September's results demonstrated the growing importance of overseas demand to China's battery industry, spanning both vehicle batteries and energy storage products.

Nine-Month Battery Exports Record Strong Annual Growth

During the first nine months of 2026, combined exports of power and energy storage batteries reached 302.9 GWh, an increase of 51.6% year-over-year. Power battery exports rose 54.7% to 199.7 GWh, while energy storage battery exports increased 45.9% to 103.2 GWh. According to CABIA, power battery exports grew faster than energy storage battery exports during the period, primarily because vehicle exports increased and automakers' overseas factories gradually began production. This explanation connects battery export growth with the international expansion of vehicle manufacturing and sales. However, the reported figures do not identify individual automakers, destinations, or factory-level contributions, so the scale of each company's role cannot be determined from the available data.

Industry Impact & Outlook

China's battery industry is expanding across vehicle electrification and energy storage, but the September figures show that strong demand does not eliminate signs of moderating annual installation growth. LFP batteries remain central to domestic installations, while ternary batteries continue to account for a much smaller share. Rapid energy storage sales growth and rising exports broaden the industry's demand base beyond domestic vehicle production. For battery manufacturers, automakers, and energy storage suppliers, these trends underscore the importance of serving different applications and international markets. CABIA's findings also suggest that commercial NEVs and overseas vehicle manufacturing will remain relevant factors in battery demand. Future performance will depend on how installation growth, battery chemistry shares, energy storage sales, and exports evolve in subsequent reporting periods.
