World’s first 100% silicon anode EV battery unveiled, charges in 8.5 minutes
ProLogium's 100% silicon composite anode battery.
ProLogium Technology
ProLogium Technology, which specializes in the development and production of lithium ceramic batteries, has unveiled its 100 percent silicon composite anode battery.
The battery made its premiere on October 14 at the Paris Motor Show.
According to a press release by ProLogium, the battery technology has been adopted in partnership with Germany’s FEV Group to make a next-generation battery pack.
The company says that the next-generation LCB battery surpasses traditional lithium-ion batteries in energy density and charging efficiency. It’s a step forward in the process of commercialization of lithium ceramic batteries, marking a significant step towards its adoption in the industry.

Features of the silicon composite anode battery
ProLogium’s 100 percent silicon composite anode enhances energy density and fast-charging performance, the company said in the press release.
The system currently achieves 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.”
When compared to traditional lithium iron phosphate battery (under 200 Wh/kg), and Lithium-Nickel-Manganese-Cobalt battery (NCM) battery (200 to 300 Wh/kg), the ProLogium LCB has surpassed them in performance.
As per the company’s claims the gap is expected to widen up to 77 percent by the end of 2024.
The test data from TÜV Rheinland shows that the cell can charge from 5 percent to 60 percent in just five minutes and reach 80 percent in 8.5 minutes. This greatly impacts the vehicle range, and also significantly reduces charging time.
ProLogium has introduced the “Small Battery, Big Future” concept, which is aimed at revitalizing the EV industry by offering a potent blend of efficiency, performance, and sustainability.
“With only 66% of the total energy capacity of current lithium-ion batteries (from 83 kWh to 55 kWh), ProLogium has cut vehicle weight by 300 kg (661 pounds), the press release mentioned.
Driving range boost for EVs
While the weight cut will benefit the electric vehicles (EVs) using ProLogium’s technology, they will also benefit from the 186 miles (300 km) approximate range that it can get from just a five-minute charge.
This outpaces the industry’s current 30-minute average charging time and reduces the wait time by a massive 83.3 percent.
The company also unveiled its strategic partnership with FEV at the Paris Motor Show, to showcase how the battery packs are being integrated into EVs.
The collaboration also marks ProLogium’s progress from making EV parts to developing cell modules and packs.
Moreover, the use of modular cell design also allows for easier repairs and facilitates cell recycling, reducing maintenance costs and increasing the resale value of used electric vehicles.
“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,” stated Vincent Yang, ProLogium’s founder and chairman.
Dmitry Belov, Chief Scientist of ProLogium Technology, stated, “Our new technology has broken through existing barriers. Since 2023, we’ve consistently outperformed our competitors, with the gap only growing larger, in both energy density and in fast-charging performance.”
