Taiwanese solid-state battery manufacturer ProLogium Technology Co. is entering the heavy equipment battery market, aiming to lead the next generation of energy storage solutions. The company, which is currently commercializing its fourth-generation lithium ceramic battery (LCB), has announced a strategic partnership with Kyushu Electric Power to develop advanced batteries specifically for the construction and heavy machinery industry.
According to ProLogium on May 9, the two companies will jointly develop a 24V LCB module tailored for construction equipment applications. They plan to unveil the technology at CES 2026, the world’s largest consumer electronics show, to be held in Las Vegas next year.
The collaboration combines ProLogium’s cutting-edge battery technology with Kyushu Electric’s expertise in module design and end-user system integration. ProLogium will supply its lithium ceramic batteries, while Kyushu Electric will develop the 24V modules and lead integration for use in heavy machinery.
ProLogium ‘s LCBs offer enhanced safety, higher energy density, superior low-temperature performance, and reduced maintenance costs compared to conventional lithium-ion batteries. These features make them suitable not only for electric vehicles but also for industrial and heavy-duty applications.
The company’s fourth-generation LCB, unveiled earlier this year as the world’s first of its kind, delivers an energy density of 380 Wh/kg, up from 359 Wh/kg in its third-generation version. Charging speeds have also improved significantly, with the battery reaching 60% in just 4 minutes and 80% in 6 minutes-compared to 5 and 8.5 minutes for the previous generation.
The LCB also operates reliably at temperatures as low as -20캜 and uses an inorganic solid electrolyte, which dramatically reduces fire risk. At high temperatures, it activates an Active Safety Mechanism to prevent thermal runaway. The battery has passed extreme-condition testing at 300캜, 20V, and 250% overcharge, demonstrating its exceptional safety.
Through this collaboration, ProLogium and Kyushu Electric aim to accelerate the decarbonization of the construction and heavy industries by offering sustainable battery solutions that reduce emissions, cut pollution, and improve energy efficiency. The companies also plan to expand their partnership into other energy-related applications to foster a future-ready industrial ecosystem.
“This partnership with Kyushu Electric will allow us to bring our next-generation LCB technology to heavy machinery, enhancing energy efficiency, safety, and durability,” said Vincent Yang, founder and chairman of ProLogium. “Together, we will deliver long-range energy solutions, enable fast charging, and ensure stable performance in extreme environments.”
Founded in 2006, ProLogium specializes in the development and manufacturing of lithium ceramic batteries. In 2022, the company received a $50 million equity investment from South Korea’s POSCO Holdings.
Kyushu Electric Power supplies electricity to Japan’s Kyushu region-including Fukuoka, Saga, Nagasaki, Oita, Kumamoto, Miyazaki, and Kagoshima-and is also involved in telecommunications, IT services, facility construction and management, LNG operations, real estate, and environmental services.
