EV Batteries and Charging: LFP, Solid-State, CATL, LG — 2026-09-12
LG Energy Solution and Seoul National University announced a breakthrough in Lithium Manganese-Rich (LMR) battery stability, potentially enabling cheaper 400-mile EVs. Meanwhile, CATL and BYD continued to dominate global market share with Chinese manufacturers holding over 72% of the market, while Korean battery makers aggressively targeted the ESS sector to offset EV demand slowdowns.

LG Energy Solution Stabilizes LMR Batteries for Cheaper Long-Range EVs
On September 9, 2026, LG Energy Solution reported significant progress in stabilizing Lithium Manganese-Rich (LMR) cathodes in collaboration with Seoul National University. The new approach addresses gas generation issues that have historically hindered LMR commercialization, paving the way for batteries capable of 400-mile ranges at a cost lower than current LFP solutions. This development is critical for reducing reliance on expensive cobalt and nickel while maintaining high energy density for mass-market electric vehicles.
CATL and BYD Drive China’s 30% Cost Advantage in EV Batteries
A report published on September 7, 2026, highlighted that Chinese battery packs are now approximately 30% cheaper than their Western counterparts, driven by CATL and BYD’s dominance in LFP production. The falling prices of LFP cells have solidified China's cost advantage, forcing global automakers to reconsider supply chain strategies. This price disparity underscores the structural challenges facing non-Chinese manufacturers in competing on cost for standard-range EVs.
Global EV Battery Market Share: CATL Leads with 39.9%
SNE Research data released on September 7, 2026, confirmed that CATL held a 39.9% share of the global EV battery market from January to July 2026, followed by BYD at 14.7%. The top seven Chinese companies collectively controlled 72.8% of the global market, indicating a deepening consolidation among Chinese suppliers. This dominance highlights the difficulty for companies like LG Energy Solution and Panasonic to gain significant ground outside their home regions or specific partnerships.
Korean Battery Makers Pivot to ESS Amidst EV "Chasm"
As of September 7, 2026, LG Energy Solution, Samsung SDI, and SK On are intensifying their competition for large-scale Energy Storage System (ESS) contracts, particularly for Tesla’s Megapack demand. This strategic shift aims to offset the "chasm" (slowing demand) in the EV sector by leveraging the booming grid storage market. SK On recently secured a $1.5 billion contract in the US, signaling that ESS has become a primary growth engine for Korean battery giants.
Local view
South Korean media outlets are closely watching the "Black and White" competition between LG Energy Solution and Samsung SDI for dominance in the AI-driven ESS market. Reports from Shinailbo highlight that both companies are vying for leadership as data center energy demands surge, positioning ESS as the key to sustaining profitability during the EV slowdown.
Chinese media, including NTDTV, reported on September 10 that CATL’s market capitalization dropped by over 520 billion RMB, sparking debates about valuation sustainability despite its market share lead. Analysts suggest this volatility reflects broader concerns about geopolitical risks and pricing pressure in the battery sector.
Context & numbers
- Market Share: CATL (39.9%), BYD (14.7%), Top 7 Chinese Firms (72.8%) of global EV battery market Jan-Jul 2026.
- Cost Differential: Chinese EV battery packs are ~30% cheaper than Western equivalents due to LFP scale.
- Korean Financials: LG Energy Solution, Samsung SDI, and SK On all returned to profitability in Q2 2026, largely driven by ESS sales rather than EVs.
On the radar
- Solid-State Timeline: Industry consensus remains that commercial solid-state EV adoption is unlikely before 2027-2030, with current focus remaining on improved liquid electrolyte chemistries like LMR and LFP.
- US Regulatory Shift: The US is moving to restrict Chinese-connected ESS equipment from power grids, creating a potential opportunity for Korean and Japanese suppliers to fill the gap.
