EV Batteries and Charging: LFP, Solid-State, CATL, LG — 2026-09-02
SK On secured a massive $1.5 billion, 9 GWh LFP battery contract with US energy storage company Neovolta Power, marking a pivotal shift from EV to ESS production for Korean manufacturers. Simultaneously, LG Energy Solution finalized a decade-long lithium supply agreement with Smackover Lithium to secure US-based raw materials, while CATL aggressively expanded its direct-to-customer sales platform, signing over 1,800 firms to bypass distributors.
EV Batteries and Charging: LFP, Solid-State, CATL, LG — 2026-09-02
Top developments
SK On lands $1.5B US ESS deal, pivoting Georgia EV lines
On August 27, 2026, SK On announced a definitive supply agreement with US-based Neovolta Power to deliver 9 GWh of LFP battery cells starting in 2027. The contract, valued at approximately 1.5 trillion KRW ($1.5 billion), represents a nine-fold increase in confirmed volume compared to SK On’s first US ESS contract last year. To fulfill the order, SK On will convert its Georgia-based EV production lines to manufacture ESS cells locally, aligning with US domestic sourcing requirements and capitalizing on the "de-Chinization" of the North American grid storage market.
LG Energy Solution secures 10-year US lithium supply
LG Energy Solution announced on September 1, 2026, a long-term supply agreement with Smackover Lithium. Starting in 2029, LGES will source 8,000 tons of lithium annually from the US-based producer. This move strengthens LGES’s domestic supply chain resilience against geopolitical risks and supports its growing portfolio of US-based battery plants, including the newly operational Lansing facility which produces cells for Tesla and Toyota.
CATL cuts distributors with $63/kWh direct LFP sales
In late August 2026, CATL reported that more than 1,800 energy storage companies have joined "CATL Mall," its direct-sales online platform for LFP cells and modules. The platform offers cells at approximately $63/kWh, bypassing traditional distributors to lower minimum order barriers and accelerate shipping for smaller B2B buyers. This strategy aims to lock in smaller ESS integrators who might otherwise source from cheaper, lower-quality competitors, reinforcing CATL’s dominance in the global stationary storage market.
Chinese market data shows LFP dominance hits new high
According to data released in late August 2026 by the China Automotive Battery Innovation Alliance, LFP batteries accounted for 84.6% of total domestic power battery installations in July 2026. This record share underscores the continued price-driven preference for LFP in China’s EV market, where CATL and BYD remain the top two installers. The data highlights that despite solid-state hype, LFP remains the overwhelming standard for mainstream EVs due to cost and safety advantages.
Local view
Korean Media (Sedaily, Maeil Business): Korean financial outlets are closely watching the "ESS pivot" as a lifeline for domestic battery makers facing EV demand stagnation (the "chasm"). Sedaily reports that SK On’s single contract fulfilled half of its annual overseas ESS target, signaling a successful strategic shift. Maeil Business notes that while LG Energy Solution and Samsung SDI have larger overall footprints, SK On’s aggressive conversion of EV lines to ESS in Georgia is a unique, high-risk/high-reward bet that has now paid off with major orders.
Chinese Media (Zhihu, CarNewsChina): Chinese tech analysts emphasize CATL’s direct-sales model as a disruption to the traditional battery supply chain, allowing CATL to capture margin previously held by distributors. CarNewsChina highlights that this move pressures smaller battery makers who cannot compete on price or logistics efficiency. Additionally, discussions on Zhihu point to the 84.6% LFP market share as evidence that Chinese consumers prioritize cost and range over premium chemistry features like high-nickel NMC.
Context & numbers
- SK On Contract Value: ~$1.5 billion (1.5 trillion KRW) for 9 GWh of LFP cells over 5 years.
- CATL Direct Sales Price: Approximately $63/kWh for LFP cells via CATL Mall.
- China LFP Market Share: 84.6% of total domestic installations in July 2026, a historic high.
- LGES Lithium Supply: 8,000 tons/year starting 2029 from Smackover Lithium.
- Korean ESS Market Share: In H1 2026, LGES held 13.6% and Samsung SDI held 6.1% of the North American ESS market, benefiting from US tariffs on Chinese batteries.
On the radar
- Solid-State Reality Check: LG Energy Solution executives reiterated in mid-August interviews that significant technical challenges remain for solid-state batteries, tempering expectations for near-term mass adoption despite industry hype.
- Sodium-Ion Cost Parity: CATL spokespersons confirmed in late August that sodium-ion battery costs are expected to reach parity with LFP by the end of 2026, potentially disrupting the low-cost EV and stationary storage segments further.
- US Charging Network Reliability: While not a battery news item per se, recent Q1 2026 data showed Tesla’s network maintaining high uptime even after absorbing non-Tesla vehicles, setting a benchmark for interoperability that battery makers must consider for user experience.
