On December 25, CNGR and Sunwoda signed a strategic cooperation framework agreement focused on advancing solid-state battery technology. The signing follows Sunwoda’s recent milestone of producing its one-millionth 684 Ah laminated large battery cell on December 23. This partnership aims to accelerate the commercialization and industrialization of solid-state batteries by combining the two companies’ strengths across materials, manufacturing, and global capacity planning.
Solid-state batteries are regarded as a cornerstone of next-generation energy technology, offering higher energy density and enhanced safety compared with conventional lithium-ion cells. These advantages address key industry challenges, including range anxiety in electric vehicles and safety concerns in energy storage systems. Under the agreement, CNGR and Sunwoda will collaborate on precursor technology development, cathode material research, product supply, and worldwide production network layout.
The cooperation will proceed along three main tracks:
- Joint R&D of new cathode material precursors specifically tailored for solid-state applications, emphasizing high energy density, robust safety characteristics, and extended cycle life to meet the performance demands of electric vehicles and grid storage.
- Integrated development of battery materials and full cell prototypes, leveraging each partner’s expertise in material science, manufacturing processes, and engineering scale-up. This approach will ensure close alignment between material properties and overall cell performance, meeting stringent industry requirements.
- Coordinated scaling of production capacity for both materials and cells, combining CNGR’s and Sunwoda’s manufacturing infrastructures to expedite the industrial rollout of solid-state battery components.
Sunwoda’s achievement in delivering one million 684 Ah laminated cells within three months of starting mass production in September demonstrates its process maturity and engineering scalability. The rapid delivery underscores the company’s ability to overcome large-scale production bottlenecks and offers a pathway to safer, more reliable energy storage solutions.
By uniting their capabilities, CNGR and Sunwoda plan to bring solid-state battery materials and systems to market more quickly, supporting the broader transition to clean energy and electrified transportation.
