ProLogium Technology is working towards starting pilot production of its fourth-generation lithium ceramic battery (LCB) with a fully inorganic electrolyte by the end of 2025. Increasing the inorganic content to 100% enhances energy density, charging speed, low-temperature reliability, and safety. The fourth-generation LCB achieves specific energy of 380 Wh/kg and energy density of 860-900 Wh/L, outperforming the third-generation battery in terms of range, cost reduction, and enabling lighter and more efficient designs through thick-film and bi-cell technologies.
The company’s ceramic separator and advanced wet film coating technology deliver three times the thermal conductivity of traditional liquid batteries, ensuring stability under high-load conditions like high-speed driving. The large-format cell designs also enhance heat dissipation, while the planar liquid cooling system reduces reliance on active cooling and improves overall energy efficiency. The battery is designed to deliver consistent range performance even at -20°C, making it suitable for various weather conditions and applications.
Unlike conventional lithium-ion or sulfide-based batteries, ProLogium’s fully inorganic electrolyte is non-flammable under extreme heat or voltage. The battery features an advanced Active Safety Mechanism (ASM) that prevents thermal runaway by activating automatically at high temperatures. In overcharge tests, the battery remained fireproof and non-combustible, achieving a Hazard Level of 2-3. These safety features make the battery ideal for a wide range of applications where reliability and safety are paramount.
ProLogium is working towards surpassing 450 Wh/kg and 1,000 Wh/L with lithium metal anodes by 2026, as part of their ongoing research and development efforts. This continuous improvement in energy density and specific energy will further enhance the performance and capabilities of their batteries, making them even more competitive in the market. The company is committed to pushing the boundaries of battery technology and delivering innovative solutions that address the evolving needs of various industries.
Vincent Yang, the founder and Chairman of ProLogium, is optimistic about the future of the company’s battery technology. He believes that the advancements made in the fourth-generation LCB and the ongoing research towards lithium metal anodes will enable them to achieve their goals and continue to lead the industry in terms of energy density and performance. ProLogium’s focus on innovation, safety, and efficiency makes them a key player in the development of advanced battery solutions for electric vehicles, consumer electronics, and other applications. Their commitment to sustainable and reliable energy storage solutions will shape the future of battery technology.
