On December 25, Cngr Advanced Material Co.,Ltd. (Zhongwei) announced the formal signing of a Strategic Cooperation Framework Agreement for Solid-State Batteries with Sunwoda Electronic Co.,Ltd. (Sunwoda). The collaboration will focus on the research, development, and industrialization of key materials for solid-state batteries, primarily targeting two major application scenarios: new energy vehicles and energy storage systems.
According to the agreement, the cooperation will concentrate on three main directions: firstly, the joint development of novel precursor materials for cathodes suitable for solid-state batteries, which must possess characteristics of high energy density, high safety, and long cycle life; secondly, Sunwoda will take the lead in developing cathode materials and complete cells compatible with solid-state battery systems based on precursors provided by Zhongwei, promoting their practical application in fields such as energy storage; thirdly, the two parties will jointly explore mass production pathways to advance the large-scale commercialization of solid-state battery materials.
Zhongwei is a leading global supplier of ternary precursors with deep expertise in high-nickel, single-crystal, and other high-end precursor technologies. Sunwoda, building on its foundation in lithium-ion battery manufacturing, has consistently invested in the R&D of semi-solid and all-solid-state batteries in recent years and has already established a dedicated product line for energy storage batteries. This collaboration aims to integrate the "materials-cells-application" chain, specifically addressing the stringent safety and cycle life requirements of large-scale energy storage projects, thereby accelerating the transition of solid-state battery technology from the laboratory to engineering applications.
The announcement noted that solid-state batteries offer potential advantages in the energy storage sector, including the suppression of thermal runaway risks, extended service life, and simplified thermal management systems. Through this partnership, Zhongwei hopes to more precisely align its precursor products with end-market demands, tackle key technical bottlenecks such as interface compatibility between the cathode and electrolyte in solid-state systems, and simultaneously provide stable material supply solutions for the energy storage market.
Both parties stated that they will subsequently establish a joint technical team to advance material verification and pilot testing, and will assess the possibility of jointly building supporting production capacity. This signing marks a substantive step forward for both companies on the path to next-generation battery technology and provides a new model of cooperation for the domestic energy storage industry in exploring high-safety, long-duration energy storage technologies.
