The Chinese company WeLion has just launched the production of its first semi-solid batteries. These will notably equip the Nio ET5 and ET7 and should in particular allow them to increase their autonomy, up to 1,000 km in specific conditions. But this technology also has other major advantages.
Displaying better energy density and less prone to overheating, they can accommodate more cells. Result, the pack is more compact and lighter allowing to offer a greater autonomy. It could then be a very effective response to the still high price of batteries, when the only currently viable solution is simply to integrate smaller accumulators into cars.
A strategy notably envisaged by Renault. The French manufacturer is also working on solid batteries, with the help of Airbus.
