The Chinese energy storage integrator HyperStrong $688411 recently concluded a strategic cooperation agreement with the battery manufacturer CATL $3750 (-1,87%) has concluded.
According to a press release published by the company via its WeChat account on November 17, this lays the foundation for one of the largest long-term supply contracts for battery cells in the industry.
Under the agreement, HyperStrong will purchase at least 200 GWh of battery cells from CATL between January 2026 and December 2028. This volume is intended to secure the rapid expansion of the company's grid-connected storage capacities.
Beyond cell procurement, the agreement establishes a long-term coordination framework until 2035.
The two companies will update their joint business objectives every three years, with each update formalized in an annual cooperation agreement. This mechanism is intended to provide both parties with greater transparency regarding future demand and supply planning as the global storage market grows.
HyperStrong and CATL also plan to expand their collaboration to new business models.
Potential initiatives include joint investment funds for energy storage projects and an integrated project development and operations platform covering development, investment, operations and maintenance.
The companies will also explore joint procurement of components for power conversion systems to optimize the supply chain and improve resource efficiency in their joint ecosystem.
HyperStrong, one of China's leading suppliers of energy storage systems (ESS), has long been a close downstream partner of CATL. CATL said the extended ten-year collaboration will deepen complementary strengths in R&D, smart manufacturing and global market expansion, and accelerate the deployment of large-scale energy storage in new energy system architectures.
HyperStrong added that the agreement solidifies a stable, long-term partnership that will enable the two companies to integrate resources more efficiently and strengthen their competitiveness. In the future, both sides aim to intensify joint innovation, overcome technical barriers in large-scale energy storage and support the industrial upgrading of the sector - contributing China's strength to the global energy transition.
