A ceramic battery manufacturer introduced a solid-state battery architecture that will give future electric vehicles (EVs) a range of 186 miles (300 km). In just five minutes, the battery may be charged from 5% to 60% capacity.
At the 2024 Paris Motor Show, ProLogium executives unveiled the design and asserted in a statement that their silicon composite anode battery had a much higher energy density, both by weight and volume, than well-known lithium-ion (Li-ion) or lithium iron phosphate (LFP) batteries.
Germany’s TUV Rhineland has confirmed the capacity at 749 Watts per liter (Wh/L) volumetrically (power by volume) and 321 Watts per kilogram (Wh/kg) gravimetrically (power by weight). Compared to existing technologies, which offer less than 200 Wh/kg for LFP or 200 to 300 Wh/kg for Li-ion, the new battery is far denser.
Executives at ProLogium predict that additional developments will allow their silicon anode batteries to offer energy densities up to 77% higher by the end of 2024. They also pointed out that the industry average of thirty minutes to reach the same distance capacity is much longer than the five-minute charging time to reach 186 miles (300 km).
Officials further claim that the modular design of the ProLogium battery greatly simplifies servicing, maintenance, and repair. In particular, the costly replacement of the entire battery pack won’t be necessary if damage is sustained to a single battery cell or a small group of cells.
