BYD is developing a sulfide all-solid-state battery with an energy density of 400 Wh/kg, achieving a driving range exceeding 1,000 km. It is expected to be installed in small batches by 2027 and achieve "solid-liquid parity" by 2030, with deployment in 40,000 vehicles.

September, a critical period for the sodium-ion battery industry's push towards mass production, saw differentiated performance across the industry chain segments — production of some materials surged YoY but faced pressure MoM, some segments maintained growth resilience, while mass production bottlenecks, cost pressure, and demand fluctuations remained common challenges for the industry. From cathode and anode to electrolyte and battery cell end-users, operational details and future expectations across segments collectively outline the current development profile of the sodium-ion battery industry.

The latest Renewable Energy 2025 report released by the International Energy Agency shows that, due to recent policy adjustments by the Trump administration, the agency has lowered its forecast for US renewable energy growth through 2030 by 50%.

(Yicai) Oct. 9 -- A research team led by Huang Xuejie, a professor at the Chinese Academy of Sciences' Institute of Physics, is developing the world's first technology to achieve "zero external pressure sulfide electrolyte all-solid-state lithium battery," which offers a solution for such batteries' interface challenges that hinder their mass production.

[SMM Analysis: Lithium Battery Entire Industry Chain Enters Peak Season in September, End-Use Demand Expected to Continue Increasing] SMM October 10: In September, China's monthly lithium carbonate production continued to hit new highs, up 2% MoM and significantly up 52% YoY; lithium hydroxide production surged 26% MoM; cobalt sulphate production rose 8.24% MoM and increased 17.6% YoY; Co3O4 production showed significant growth, up 9% MoM and 40% YoY; ternary cathode precursor production continued its strong growth trend, up 12.28% MoM and 22.05% YoY; ternary cathode material production maintained strong growth, up 13.55% MoM and 23.44% YoY; iron phosphate production surged 17% MoM and increased 58% YoY; LFP material production increased approximately 12.8% MoM and 42% YoY, with an industry operating rate of about 68%; LCO market showed steady growth, with monthly production achieving a slight increase, up 3% MoM and significantly climbing 55% YoY.

[SMM Analysis: Focusing on Graphite Anode Export Controls: Decoding Industry Reshaping and Global Changes Driven by New Policies] SMM October 10 News: Announcement No. 58 of 2025 from the Ministry of Commerce and the General Administration of Customs announced the decision to implement export controls on items related to lithium batteries and artificial graphite anode materials. These control measures will officially take effect from November 8, 2025.

Currently, the price increase in the sulfate segment has not been fully passed on to downstream battery cell manufacturers, and battery cell manufacturers have very limited acceptance of the rise in ternary cathode material prices. Under cost pressure, cathode plants also have relatively limited acceptance of the increase in the discount coefficient for upstream ternary cathode precursors.

The market generally expects prices to continue their upward trend, with a strong wait-and-see sentiment prevailing in the initial post-holiday period, leading to relatively cautious trading performance.
