Manufacturer produces electric vehicle battery with 620-mile range

Electric vehicle (EV) battery manufacturer Gotion High Tech, which supplies Volkswagen, has revealed the Astroinno L600 with a range of 1,000km (620 miles).

Gotion has spent the past 10 years developing the lithium manganese iron phosphate (LMFP) battery having wanted to improve the energy density of lithium iron phosphate (LFP) batteries.

Dr Qian Cheng, the executive president of Gotion Global, said: "Astroinno L600 LMFP cell achieves 240Wh/kg in gravimetric energy density and 525Wh/L for volumetric energy density.

“It can achieve more than 4,000 cycles at room temperature and 1,800 cycles at high temperature, easily achieves 18 minutes of fast charging, and passes all safety tests.”

He added: “Because of the high energy density of Astroinno battery, we can also achieve a range of 1,000km (620 miles) without relying on NCM (nickel manganese cobalt) material."

In terms of battery design, it has also reduced the number of structural parts by 45% and lowered their weight by nearly a third, while the wiring required has fallen from 303 metres to 80 metres 

Gotion expects to start mass production of the L600 battery cell in 2024.

The 620-mile range quoted by Gotion would be a huge increase in terms of what is currently available on the market. Volkswagen’s new electric ID7 upper-medium car, for example, will have a range of up to 438 miles. 

An electric concept car from Mercedes-Benz, the Vision EQXX, did manage to cover more than 1,200 km (746 miles) on a single charge, last year.

It travelled the distance in real-world driving conditions from Stuttgart in Germany, to Silverstone in the UK, surpassing the 1,000 km (620 miles) record it had set in April, 2022. 

The car uses a 100kWh battery, which is ultra-compact, with a footprint that is 50% smaller and 30% lighter than the 107.8kWh pack used in the Mercedes EQS.

It achieved an average consumption of 8.3kWh/100km, more than double that of the EQS.
