ProLogium showed a Li-Ion battery with a silicon anode and a density of 321 Wh/kg

Company ProLogium she is not unknown to us. We have written about her upcoming lithium batteries on the SHW website more than once, and now she showed them at the Paris Motor Show. Its novelty has already received certification from TÜV Rheinland and brings quite good features. It uses composite silicon anodes, which makes it possible to increase the energy density of accumulators. While, according to the company, LFP batteries are usually under 200 Wh/kg and NMC batteries between 200 and 300 Wh/kg (well, we know even higher ones), its novelty can boast a value of 321 Wh/kg, which is definitely not a bad number (according to the data in the photo but that comes out to 295 Wh/kg). As for the volumetric energy density, it is 749 Wh/l, which is also a good value. A version with better 355 Wh/kg and 823 Wh/l should be introduced before the end of the year.

Fast charging should also be an advantage of these accumulators. It should take 5 minutes from 5 to 60%, then 8.5 minutes to 80%. This is to reduce the charging time, which according to the company and its vision “Small Battery, Big Future” can also be used for the fact that cars will have smaller batteries, which will be charged more often, but much faster. If only 55kWh were used instead of an 83kWh battery, the lower amount of stored energy and greater energy density would mean that such a battery could be 300kg lighter. Along with faster charging in 5 minutes, which should be enough to drive 300 km, the company would like to reduce charging by 5/6 compared to today’s 30-minute charging. ProLogium goes on to say that one charging stand would thus be able to service 12 EVs per hour instead of today’s two.
