ProLogium, FEV show 100% silicon battery

ProLogium Technology has shown its 100% silicon composite anode battery at the 2024 Paris Motor Show being used by FEV.

The fast charging silicon battery developed by ProLogium has been certified by TÜV Rheinland and is being used by FEV Group to develop a next-generation battery pack.

The battery system has a volumetric energy density of 749 Wh/L and a gravimetric energy density of 321 Wh/kg, with projections to increase to 823 Wh/L and 355 Wh/kg by the end of 2024. This provides a range of 300km with a five minute fast charge.

This compares to mainstream LFP batteries at under 200 Wh/kg, and NCM batteries at 200 to 300 Wh/kg, although prototype batteries are reaching 800Wh/l.

According to TÜV Rheinland test data, the battery charges from 5% to 60% in just 5 minutes and reach 80% in 8.5 minutes.

“Our next-generation battery technology effectively addresses many of the challenges in the electric vehicle industry. Our goal is to be a game changer in the market, injecting new energy into the electric vehicle sector,” said Vincent Yang, ProLogium’s Founder and Chairman.

ProLogium says the battery can cut vehicle weight by 300 kg, boosting both energy efficiency and driving range. A modular design allows for easier repairs and facilitates cell recycling, reducing maintenance costs and increasing the resale value of used electric vehicles.

Dr. Thomas Hülshorst, Global Vice President Electric Powertrain at FEV, stated: “Over the past two years, our collaboration has resulted in customized battery packs and concept designs that not only meet, but exceed regulatory standards and market demands. Due to the significantly increased energy density of the LLCB cell of 321Wh/kg, the energy storage system can be designed to be smaller and lighter for a vehicle with a targeted driving range, thus reducing power and space requirements. By combining ProLogium’s visionary technology with FEV’s engineering strengths, we are paving the way for the future of sustainable mobility.”
