Over the years, ProLogium has built a strong global presence, supplying nearly 12,000 solid-state battery sample cells to car manufacturers for testing and module development. With over 900 patents, the company demonstrates its commitment to advancing battery technology and driving the transition to a sustainable energy future.
Battery Technology
ProLogium’s lithium ceramic battery (LCB) technology represents a significant advancement in the battery market. The company’s “film-free” design replaces traditional polymer film separators with a ceramic separator, enhancing safety, energy density, and fast charging capabilities. This innovation reduces interfacial resistance and allows for the use of advanced materials like silicon composites and ultra-thin lithium metal, improving ionic conductivity and material stability. The batteries achieve high energy density, with the fourth-generation LCB reaching up to 380Wh/kg and 860-900Wh/L, with plans to surpass 450Wh/kg and 1000Wh/L by 2026. ProLogium’s batteries also support fast charging, enabling charging from 5% to 80% in 8 minutes, and in some configurations, from 5% to 60% in just 5 minutes. These features make the batteries ideal for automotive power solutions, consumer electronics, wearable devices, and industrial applications. The company’s streamlined manufacturing process reduces core steps from 17 to 13, eliminating time-consuming tasks like polymer film placement, electrolyte injection, and degassing, resulting in faster production times and reduced capital expenditure.
Recent Projects
At CES 2025, ProLogium unveiled the world’s first fully inorganic electrolyte battery, a milestone in battery technology. This fourth-generation LCB system increases inorganic content to 100%, enhancing energy density, charging speed, low-temperature reliability, and safety. The company also presented five transformative technologies aimed at creating a sustainable ecosystem for electric vehicles. In October 2024, ProLogium debuted the world’s first 100% silicon composite anode battery at the Paris Motor Show, achieving volumetric energy density of 749 Wh/L and gravimetric energy density of 321 Wh/kg. The company has expanded its manufacturing capabilities, starting production at its first gigawatt-hour scale demonstration line in Taoyuan, Taiwan, and opening its first overseas R&D center in Paris-Saclay, with plans for a gigafactory in Dunkirk, France, set for mass production by 2027.
Investors
ProLogium Technology has received investments from a variety of prominent investors, including China Reform Fund (CRFM), VinFast, POSCO, Mercedes-Benz, SoftBank China Venture Capital, Primavera Capital Group, dGav Capital, SBCVC Navitas Limited, and Carna Investments Holding Limited. The company has raised a total of $785.74 million over 10 funding rounds, supporting its mass production plans and global capacity expansion.
