CATL’s first sodium-ion battery is used in Chery models

On June 10, news emerged that General Motors has reached a strategic cooperation agreement with US energy storage company Peak Energy to jointly develop sodium-ion battery technology for grid-side energy storage applications. The two parties will combine Peak's passive cooling energy storage technology with General Motors' battery cell research and development expertise, aiming to create the world's most cost-effective and reliable energy storage battery. Under the cooperation, General Motors will use its battery laboratory in Michigan for dedicated research and development of sodium-ion battery cells, while Peak Energy will integrate these sodium-ion cells into its proprietary energy storage systems.

After both sodium-ion battery cathodes and hard carbon anodes recorded significant increases YoY and MoM in May, the midstream and downstream segments of the industry chain—electrolytes and battery cells—also delivered impressive results, yet structural issues lurk beneath the growth.

In May, key materials for sodium-ion batteries sustained their strong momentum, with both cathode and hard carbon anode recording sharp YoY and MoM growth. Top-tier players’ order books were full and capacity utilization rates approached their limits. On the supply side, the pattern of rising volumes and stable prices was pronounced, yet pressure to pass on rising raw material costs was also building.
