EV Batteries and Charging: LFP, Solid-State, CATL, LG — 2026-09-24
CATL started trial production at its largest overseas plant in Debrecen, Hungary, while facing a shareholder-value squeeze as automakers diversify away from a single battery supplier. Korea's big three — LG Energy Solution, Samsung SDI and SK On — are battling over the country's largest-ever ESS tender at 1.18GW. Chinese media also flagged CATL's 46.7% domestic passenger-car battery share for H1 2026, even as its market cap has shed over 700 billion yuan.

CATL's Debrecen gigafactory begins trial production
On September 22, CATL's new cell plant in Debrecen, Hungary officially began trial production. The planned total capacity is 100 GWh, making it CATL's largest overseas manufacturing base; it was announced in 2022 and took four years to build, supplying European customers including Mercedes-Benz, BMW, Stellantis and Volkswagen. This is a key milestone for European localization of Chinese battery supply.
Automakers diversify away from CATL; market value down 700 billion yuan
Chinese-language coverage describes a 2026 shift toward multi-supplier battery sourcing: AITO has added second-tier suppliers, Xiaomi is developing in-house batteries, and Li Auto plans self-developed cells. Despite CATL's H1 2026 net profit of 43.28 billion yuan, its share price has fallen more than 35%, erasing over 700 billion yuan in market value. Analysts note the push is about bargaining power rather than full replacement, citing manufacturing chief Ni Jun's argument that full-solid-state mass production cycles are long and automakers can't easily make batteries themselves.
Korea's big three fight over record 1.18GW ESS tender
Korea's third ESS central contract market auction is the largest ever at 1.18GW — roughly double the previous round — pitting LG Energy Solution, Samsung SDI and SK On against each other in a 7.08 GWh order battle. The three firms are emphasizing domestic production capabilities, materials localization, and safety technology to win bids. Samsung SDI and SK On each defend the #1 and #2 cumulative rankings in the public central contract market, while LG Energy Solution is seeking a comeback against SK On.
CATL's domestic dominance and global share intact
CATL says its H1 2026 domestic passenger-vehicle battery installation share reached 46.7%, up 5.6 percentage points year-over-year, per the China Automotive Battery Innovation Alliance. Globally, it holds a 39.9% market share with installations approaching 300 GWh. Globally excluding China (Jan–Jul 2026), CATL leads at 34.0%, followed by LG Energy Solution and BYD, then Panasonic, SK On and Samsung SDI.
Local view
Chinese media commentary is focused on the "de-CATL-ization" (去宁德化) debate. Sina weibo posts argue CATL's brand-strength indices — 3.9 overseas and 6.0 domestically per a Nielsen IQ report — remain ahead of BYD and LG, calling the competitive moat earned over a decade and cautioning against premature talk of displacement. Chinese tech-platform commentary also frames mid-tier automaker in-house battery efforts as targeting solid-state tech high ground rather than low-end LFP oversupply.
Korean media, including Chosun, Financial News and Ajunews, frames the record ESS tender as a test of K-battery market share and profitability at home, with LG Energy Solution in particular looking for redemption in its home market.
