China’s EVE Energy developed all-solid-state battery cells that can power the likes of flying cars and robots. The batteries are 10-Ah cells, which can be combined into 60-Ah cell batteries, and have an energy density of up to 300Wh/kg.
PRODUCTION BEGINS
These powerful new batteries will be produced in EVE Energy’s new production facility in Chengdu, Sichuan. Spanning 11,000 square metres, the new plant was inaugurated earlier this month on the 2nd of September. Overall, the plant has a production capacity of 500,000 battery cells per year and will house research and development for the company. It will be fully completed in two construction phases. The first phase will be completed by the end of the year and the second phase by the end of 2026.
The plant’s first phase will focus on the production of 60 Ah batteries. Along with this, the company’s goal is to produce 400 Wh/kg and 1000 Wh/L for its batteries by the end of 2025. Once plant construction is complete, EVE Energy will instead adjust its goal to meet 100 MWh by the end of 2026.
According to EVE Energy, these goals are a “crucial step forward” in the industrialisation of its solid-state batteries. Thus, the company announced that it would “fully commit” its R&D, finances, and production to achieve its goals.
The newest Chengdu plant joins EVE Energy’s line-up of plants across China. The manufacturer also has plants based in Malaysia and Hungary, with another facility in construction in the UK.
LONGQUAN II
The “Longquan II” are the company’s 10Ah all-solid-state battery cells with energy densities of 300Wh/kg or 700Wh/L. According to EVE Energy, these battery cells can be combined into 60Ah packs. These cells have the capacity to power the likes of humanoid robots, unmanned low altitude “flying cars,” and AI equipment. The Longquan II can power drones, which can benefit from its power-packed and efficient 300Wh/kg range.
Last year, Executive Vice President of EVE Energy’s research institute, Zhao Ruirui announced that sulfide and halide electrolytes were specifically chosen to power the Longquan II.
Surprisingly, there’s still no news regarding a Longquan series battery for electric vehicles. However, the company’s upcoming all-solid-state batteries are set to power passenger hybrid cars. According to Electrek, EVE Energy is developing mass production of solid-state cells for EVs for auto OEMs.
