Shanghai (Gasgoo)- Sunwoda Electronic Co., Ltd. ("Sunwoda") announced on December 12 that its subsidiary, Sunwoda Electric Vehicle Battery Co., Ltd. ("SEVB"), has signed a strategic cooperation framework agreement with XTC New Energy Materials (Xiamen) Co., Ltd. ("XTC New Energy"), aiming to jointly advance the industrialization and joint development of materials for solid-state batteries, with plans to expand into further commercial cooperation when the timing is appropriate.
The partnership focuses on several areas, including the development of cathode materials, electrolytes and related materials for solid-state batteries, and their eventual industrialization.
Drawing on its extensive expertise in lithium-ion and solid-state battery R&D and manufacturing, SEVB will develop high-energy-density, high-safety solid-state batteries using new cathode materials and solid-state electrolytes provided by XTC New Energy. The collaboration will involve innovations such as composite cathode ion and electron conduction network construction, high-stability electrolyte film development, and dendrite-free, high-coulomb-efficiency lithium-metal anodes to meet the commercial application demands of solid-state batteries in electric vehicles (EVs) and energy storage systems.
Solid-state batteries, considered as a key next-generation battery technology, offer advantages such as high energy density, enhanced safety, and longer lifespan. They are seen as a critical energy solution for future EVs, though challenges remain in their industrialization.
Sunwoda's progress in this field has been notable. Development of its first-generation semi-solid-state battery, with an energy density of 300Wh/kg, has been completed, while a second-generation product with a density of 400Wh/kg is undergoing pilot testing and is expected to enter vehicle validation by the end of this year.
Meanwhile, the company has achieved small-scale testing of its first-generation all-solid-state battery with an energy density of 400Wh/kg. Development of the second-generation all-solid-state battery with even higher energy density is underway. Sunwoda is also accelerating the design and construction of production lines for all-solid-state batteries, aiming to achieve mass production capabilities by 2026.
