A report from EVE Energy states that on November 18, EVE Energy and Hello Tech signed a deep strategic cooperation agreement at Hello Tech's headquarters. The two companies will engage in deep collaboration around the research, development, and industrial application of solid-state battery technology, promoting the rapid adoption of solid-state batteries in consumer-level energy storage and comprehensive green energy solutions.
The cooperation agreement was signed by Qian Qijie, Vice General Manager of Hello Tech, and Zhao Jian, from EVE Energy's User AI Product Line Sales Center. Witnessing the signing were Wang Qiurong, Board Secretary of Hello Tech, An Xinxin, Head of Battery R&D at Hello Tech, Yang Cheng from EVE Energy's C Cylindrical Battery Research Institute, and Cui Jie from the User AI Product Line Sales Center.
Zhao Jian from EVE Energy's User AI Product Line Sales Center stated: "We look forward to continuing our partnership with Hello Tech, deeply integrating solid-state battery technology innovation with market demands to provide users with safer and more efficient green energy solutions."
Hello Tech Vice General Manager Qian Qijie stated: "Joining hands with EVE Energy represents a powerful union of industrial strengths and a strategic consensus to jointly chart a future of green electricity."
It is understood that in the field of solid-state batteries, EVE Energy is not betting on a single electrolyte route—be it sulfide, oxide, or polymer—but has instead chosen a more engineering-feasible composite approach.
Recently, on October 24, EVE Energy stated during an earnings call that regarding all-solid-state batteries, the company is proceeding according to its prior plan: first establishing the pilot line, then continuously upgrading the product. Following the current pace, the company expects to launch the next-generation product in the fourth quarter.
On September 2, EVE Energy's "Longquan II" all-solid-state battery successfully rolled off the production line. The "Longquan II" is a 10Ah all-solid-state battery with an energy density of 300 Wh/kg and a volumetric energy density of 700 Wh/L, primarily targeting high-end equipment applications such as humanoid robots, low-altitude aircraft, and AI.
Previous reports also indicated that EVE Energy has formed an R&D team of over 200 people, focusing on key technologies like sulfide ceramic electrolytes and lithium metal anodes. In the first half of 2025, the energy density of lab prototype batteries is expected to reach 500 Wh/kg, with cycle life exceeding 800 cycles, placing it in the top tier domestically.
