CATL Signs 60 GWh Sodium-Ion Battery Deal for Energy Storage — April 2026 · China
CATL and Beijing HyperStrong Technology signed a strategic cooperation agreement on 27 April 2026 under which CATL will deliver 60 GWh of sodium-ion batteries for energy storage projects over three years. This is the largest sodium-ion energy storage commitment announced globally to date. CATL's Chief Scientist Wu Kai confirmed the company has resolved four core manufacturing barriers that had previously constrained scale-up: extreme water control in cell production, gas generation in hard carbon anodes, aluminium foil adhesion, and self-forming anode systems. Mass production is confirmed for Q4 2026.
India Relevance: Sodium-ion at scale could give India a lithium-independent chemistry for grid storage — critical given India's limited domestic lithium resources and the current lithium carbonate price surge of +163% YoY. Indian BESS developers should track this chemistry closely for post-2027 procurement decisions.

CATL to Launch Sodium-Ion EV Batteries Commercially in 2026, Targeting 600 km Range · China
At its April 2026 Tech Day, CATL confirmed sodium-ion batteries will enter commercial EV production this year. The world's first mass-produced sodium-ion passenger vehicle — a joint platform between Changan Automobile and CATL — was unveiled in February 2026, with full market launch expected mid-year. CATL's long-term roadmap targets 600 km range on sodium-ion cells. At scale, the cell cost is expected to be approximately 30% below LFP, while the chemistry performs significantly better in freezing temperatures — retaining ~90% capacity at -40°C versus LFP's degraded cold-weather performance.
India Relevance: If sodium-ion reaches price parity with LFP by 2027-28, it could reshape India's 2-wheeler and 3-wheeler EV battery sourcing strategies. Indian OEMs currently reliant on LFP imports from China should watch CATL's pricing announcements closely.

BYD Advances Third-Gen Sodium-Ion (10,000 Cycles) and Sulphide Solid-State Battery · China
BYD disclosed in February 2026 that its third-generation sodium-ion platform is targeting 10,000 charge cycles — significantly exceeding current LFP cycle life benchmarks of 3,000–6,000 cycles and making it attractive for long-duration grid storage applications. In parallel, BYD is developing sulphide-based solid-state batteries expected to deliver step-change improvements in energy density and fast-charging capability, with small-scale production potentially possible by 2027. BYD's dual-track approach positions it to serve both cost-sensitive mass markets (sodium-ion) and premium high-density applications (solid-state).
India Relevance: BYD supplies cells to several Indian energy storage integrators. If advanced BYD chemistries are exported, they could benefit India's commercial and industrial BESS segment by 2027-28 — particularly the telecom tower and data centre UPS segments that value long cycle life.

MIT Technology Review Names Sodium-Ion a Top 10 Breakthrough Technology of 2026 · USA
MIT Technology Review included sodium-ion batteries in its prestigious annual "10 Breakthrough Technologies 2026" list, citing the maturation of manufacturing processes, commercial viability at scale, and the technology's independence from lithium, cobalt, and nickel supply chains as the defining factors. The recognition reflects a broader shift in expert consensus — sodium-ion has moved from laboratory curiosity to commercially viable chemistry within a three-year window, largely driven by CATL's manufacturing breakthroughs and China's domestic energy storage demand.
India Relevance: MIT Tech Review's recognition will accelerate interest from Indian BESS developers and government procurement bodies in sodium-ion as a lithium-alternative chemistry. The PLI scheme and VGF programme could potentially be extended to cover sodium-ion manufacturing.

Lithium Carbonate Surges to CNY 177,000/tonne — +163% Year-on-Year · Global
Lithium carbonate spot prices in China rose to CNY 177,000 per tonne on 30 April 2026, up 1.43% day-on-day and 163% year-on-year. The sharp rally reflects two structural demand drivers: continued growth in EV battery production, and a new and substantial source of demand from data centre operators whose power storage systems require significant lithium. China has also announced plans to double national EV charging capacity to 180 GW by 2027, which is adding further battery demand. The price surge marks a sharp reversal from the 2023-2024 lithium crash and has implications for LFP and NMC cell prices in the second half of 2026.
India Relevance: Rising lithium carbonate prices will put upward pressure on LFP and NMC cell import costs for Indian BESS developers and EV manufacturers in H2 2026. This further strengthens the case for domestic ACC cell manufacturing under India's PLI scheme.
