December 26, 2025, 10:10 AM EST. Sunwoda Electronic Co., Ltd and Zhongwei New Materials Co., Ltd signed a strategic cooperation framework on December 25, 2025 to jointly develop solid-state battery materials, including cathode precursor materials and cathode materials, and to advance full-solid-state battery technologies for industrial-scale deployment. The partnership aims to accelerate the commercialization of next-generation energy storage materials, with no financial terms disclosed. Sunwoda is a major battery manufacturer supplying Li-ion cells to automakers such as BYD, SAIC, and GAC; Zhongwei supplies nickel- and cobalt-based materials and focuses on solid-state electrolytes. Sunwoda's existing polymer-based all-solid-state battery delivers ~400 Wh/kg and 20 Ah, with a reported 1,200-cycle life under low external pressure. A 0.2 GWh pilot production line was planned by end-2025 to support scale-up.
