Chinese car maker BYD’s subsidiary Findreams’ second generation blade battery is due to launch this year, reports said. Energy density is expected to reach 190Wh/kg from the present 150Wh/kg.
CarNewsChina reported that BYD Chairman Wang Chuanfu revealed development of the new battery during a recent financial report meeting. Wang Chuanfu said the second-generation blade battery will be smaller and lighter and power consumption reduced, the report said.
The original blade battery was introduced in 2020 and used lithium iron phosphate (LFP) as the cathode material. The cells are arranged into a blade-like arrangement.
BYD claims strong results from nail penetration testing. It said last year: “During the nail penetration test, the blade battery gave off no smoke or fire and the surface temperature only reached 30 to 60°C. It also withstood other extreme test conditions, such as being crushed, bent, heated in an oven to 300°C and overloaded by 260%. None of these resulted in a fire or explosion, making BYD blade battery a safety leader for the burgeoning EV market.”
