ProLogium Technology, in joint collaboration with Germany’s FEV Group, has unveiled a lithium-ceramic battery featuring a 100 percent silicon composite anode. The breakthrough technology was showcased at the Paris Motor Show late last year, marking a pivotal shift from conventional lithium-ion batteries.
The new battery achieves an outstanding energy density of 749 Wh/L and 321 Wh/kg, eclipsing traditional lithium-iron-phosphate and nickel‑manganese‑cobalt chemistries. ProLogium projects further gains to 823 Wh/L and 355 Wh/kg by end of 2024.
Independent tests by TUV Rheinland confirm rapid charging capabilities 5 minutes to reach 60 percent and just 8½ minutes to hit 80 percent effectively slashing station wait times by more than 80 percent.
Even a brief 5‑minute charge reportedly delivers nearly 300 km of driving range, a dramatic improvement over current EV benchmarks.
Leading U.S. firm Sionic Energy, leveraging Group14’s SCC55 silicon‑carbon composite, unveiled a 100 percent silicon‑anode cell boasting 330 Wh/kg energy, 842 Wh/L volumetric density, and fast charging capable of 10‑minute full recharges. This technology also demonstrates a projected lifespan of up to 1 200 full-charge cycles.
Market analysis indicates that silicon-anode batteries are on track to redefine EV and energy-storage standards. Driven by rising demand and supported by policies like the EU Green Deal and U.S. IRA the silicon battery market is forecasted to expand significantly in the next decade.
