What a headline and what a future evolving before our eyes. Chinese battery expert EVE Energy inaugurated a new production base yesterday, and to celebrate the feat, rolled one of its new all-solid-state batteries off the production line.
EVE Energy Co., Ltd. is a Chinese battery manufacturer approaching 25 years in the industry. It develops, manufactures, and delivers lithium-ion batteries and energy storage systems to OEMs around the world.
The company’s current production footprint includes facilities in at least four regions of China, in addition to a plant in Malaysia and Hungary. In 2021, EVE shared plans to erect a new lithium-ion battery research and development center and manufacturing plant in Chengdu, in the Sichuan region of southwest China.
Since then, EVE Energy has made impressive strides beyond traditional lithium-ion cells and into highly coveted all-solid-state technology. Yesterday, EVE Energy officially opened its new solid-state battery production base in Chengdu and even produced one of its new “Longquan II” cells (pictured above).
EVE to build 500k solid-state cells per year in Chengdu
EVE Energy shared details of yesterday’s solid-state production base inauguration in a release today. The new 11,000-square-meter (118,400-square-foot) facility in Chengdu is officially open, but will continue development and expansion through 2026.
As initially announced in 2021, EVE Energy’s Chengdu facility will be constructed in two phases – the first of which is expected to be completed in December. Phase one will offer the capacity to manufacture 60-Ah batteries and EVE’s “Longquan II” solid-state cells – the first of which rolled off the production line yesterday.
The Longquan II is a 10-Ah all-solid-state cell with an energy density of up to 300 Wh/kg. Per EVE Energy, mass production of these ultra-dense cells will eventually power humanoid robots, uncrewed aerial vehicles, and AI equipment.
At its new Chengdu base, EVE has already vowed to fully commit funding, equipment, and R&D resources to achieve an energy density of 400 Wh/kg by 2025. The company also stated that this week’s production launch of the Longquan series “marks a crucial step forward for Eve Energy in solid-state battery industrialization.”
Following phase one’s completion by year’s end, EVE said phase two will bolster the facility’s annual production capacity to 500,000 cells, equating to 100 MWh by December 2026.
There was no mention of any specific solid-state cells developed for electric vehicles. Still, EVE Energy is inching toward mass production of the technology while producing higher energy densities to support automotive OEMs, perhaps one day.
Last year, Zhao Ruirui, executive vice president of EVE Energy’s research institute, shared plans to launch all-solid-state batteries for Chinese passenger cars in 2026, beginning with hybrid EVs.
