en.Wedoany.com Reported - Jinghe Energy and Siyuan Battery have completed the signing of a comprehensive strategic cooperation agreement. The two parties will engage in full-chain collaboration covering the targeted research and development, large-scale mass production, full-scenario supporting delivery, and joint adaptation for terminal application scenarios of high-rate solid-state battery cells.

According to the agreement, capital and production capacity resources will be concentrated on four core segments: iterative optimization of the formulation for high-rate all-solid-state battery cells and tackling key technologies for rate adaptation; joint construction of a pilot-scale test platform and modular mass production lines to solve mass production adaptation issues; locking in annual core battery cell production capacity quotas to ensure stable supply; and joint adaptation covering four major application scenarios: large-scale energy storage power stations, new energy commercial vehicles, special power equipment, and residential distributed energy storage.

The core logic of this cooperation lies in complementing each other's weaknesses. Jinghe Energy possesses technological accumulation in the field of solid-state battery cell research and development, while Siyuan Battery has advantages in energy supporting facilities and channels. Both parties hope to enhance the industrialization efficiency of high-rate solid-state battery cells through synergy in technology, channels, mass production, and application scenarios. Specific measures include: jointly optimizing processes to reduce the mass production cost per cell; co-building dedicated mass production lines to enhance delivery capabilities; unifying quality control standards to enhance safety under extreme operating conditions; and accelerating the replacement process of traditional liquid battery cells by solid-state cells.

This signing is also regarded as a typical case of industrial chain synergy in the solid-state battery sector. The two companies believe that by jointly building a stable supply chain, they can promote the commercial implementation of high-rate solid-state battery cells and provide more stable supply solutions for upstream and downstream partners. In the future, the two parties plan to use this strategic cooperation as a starting point, focusing on the construction of benchmark projects for high-rate solid-state battery cells, thereby contributing to the upgrade of China's new energy industry.
