On August 4, Jinko ESS, a global leading energy storage enterprise, and EVE Energy, a leading lithium battery company, jointly announced that their dedicated energy storage cell joint factory has officially entered the mass production stage.
The factory completed full-link equipment commissioning in May 2025, and the production lines were fully operational in June. It will supply Jinko ESS with 5GWh of 314Ah energy storage cells annually. EVE Energy will dispatch experts to assist the joint factory in quickly reaching industry-leading standards and fully meeting Jinko ESS’s rapidly growing global energy storage business demands.
The 314Ah energy storage cells produced by the joint factory are specifically designed for commercial, industrial, and large-scale energy storage systems. They achieve full-process optimization from material selection and process parameters to quality control, significantly enhancing energy density and system integration efficiency, thereby providing cells with large single-unit capacity, long cycle life, and high safety, perfectly matching Jinko ESS’s liquid-cooled energy storage systems.
Jinko ESS CEO Zhou Fangkai stated: “The mass production of this joint factory marks Jinko ESS’s extension from system integration to core cell manufacturing in the vertical industry chain. The joint factory combines our resources and technological advantages to provide customers with outstanding energy storage cells. The 314Ah cell, deeply integrated with intelligent electrical control and liquid cooling systems, can offer safer, more efficient, and cost-effective energy storage solutions for commercial, industrial, and large-scale ground-mounted power stations.”
The global energy storage market is currently growing at an annual rate of more than 30%, and the newly installed global energy storage capacity is expected to exceed 200GWh in 2025. With the 5GWh capacity of the joint factory, Jinko ESS can provide stable and reliable energy storage solutions for global customers, creating a significant competitive advantage especially in high-growth overseas markets.
Dr. Du Shuanglong, General Manager of EVE Energy CLSBG, stated: “The mass production of the joint cell factory is an important achievement of both parties in vertical integration and technological collaboration in the energy storage industry chain. With the global energy storage market growing rapidly, EVE Energy will continue to deepen its strategic partnership with Jinko ESS, leveraging both sides’ complementary advantages in cells, systems, and markets to jointly explore cell iteration and intelligent system solutions, promoting industry upgrades.”
