Beijing Easpring Material Technology Co., Ltd. (Easpring) announced on an online investor platform that the company is making smooth progress in the technology and customer development of key materials for all-solid-state batteries.
Regarding all-solid-state cathode materials, the company's ultra-high-nickel multi-material specifically designed for all-solid-state batteries has achieved performance (cycle life, capacity, etc.) close to that of liquid electrolyte batteries. It can meet energy density requirements exceeding 400 Wh/kg, far surpassing current liquid battery levels. The ultra-high-capacity lithium-rich manganese-based material can enable all-solid-state batteries to reach 500 Wh/kg, placing it at the industry forefront.
In solid electrolyte development, Easpring has adopted a comprehensive approach covering sulfide, oxide, and halide technical routes. It has pioneered a novel chloride iodide composite sulfide electrolyte that maintains high ionic conductivity while significantly reducing interfacial stress, effectively addressing solid--solid contact challenges. The product has already entered the mass validation stage with leading clients. In the first three quarters of 2025, the company has achieved batch supply of over 20 tonnes of key materials for all-solid-state batteries.
