Eve Energy started construction of a production facility for solid-state batteries in Chengdu, China, where it will launch production of the ‘Longquan II’ all-solid-state battery cell. The first phase is to be completed by the end of 2025.
Eve Energy’s new facility will cover an area of about 11,000 m² and is intended to deliver around 500,000 cells per year once production is fully ramped up. Construction is to take place in two phases, with the first to be completed by December 2025. At that time, a production capacity for 60 Ah batteries is planned.
Phase two will be completed one year later in December 2026. Following the completion of the factory, it is to achieve an annual production capacity of 100 MWh. This is considered a “crucial step forward” by the company to advance its solid-state battery industrialisation. Eve plans to achieve an energy density of 400 Wh/kg and 1000 Wh/L for solid-state batteries by 2025. By 2026, battery production for hybrid vehicles is also planned to start.
The battery cells that Eve Energy is planning to manufacture at its new facility are ‘Longquan II’ 10 Ah solid-state battery cells with an energy density of up to 300 Wh/kg or 700 Wh/L. The manufacturer states that the battery cell is primarily intended for humanoid robots, unmanned aerial vehicles for use at low altitudes and high-quality AI devices.
Last year, Eve Energy also started looking outside of China for production locations, such as Coventry, UK. This was then put into action only a few months later. This development also came just after Chinese manufacturers placed a new focus on solid-state batteries. In the summer of 2024, Eve also announced that it had achieved a 6C charging rate for its cylindrical cells.
