ProLogium Technology, a provider of lithium ceramic battery technology, has collaborated with Japanese utility Kyushu Electric Power and Japanese construction machinery manufacturer Nakayama Iron Works. At the recent CES 2026, the companies jointly showed a 24 V solid-state battery module powered by ProLogium solid-state batteries. The module is planned for integration into two new construction machines—the MSD700 and NE100HBJ.
The new collaboration will form “a complete vertically integrated chain from battery cell to end product.” ProLogium will provide its next-generation solid-state lithium ceramic cells; Kyushu Electric Power will contribute its experience in energy technology and lithium-ion battery monitoring/control to design the battery module; and Nakayama Iron Works will integrate the new module into its construction machinery.
“ProLogium’s next-generation solid-state lithium ceramic battery features a unique super-fluidized all-inorganic solid-state electrolyte, [combined] with an active safety mechanism that is released under high temperature and high voltage to stabilize the active materials of both the cathode and anode,” said Vincent Yang, founder and CEO of ProLogium. “This enables the battery to truly interrupt thermal chain reactions and achieve the ultimate goal of eliminating thermal runaway.”
Nakayama’s MSD700 is a compact electric construction machine designed for narrow environments where large equipment is difficult to operate. It can operate safely indoors or underground severe circumstances without concerns about exhaust gases. The NE100HBJ, part of the DENDOMAN series, is a battery-driven crusher capable of crushing 15-50 tons of rock or concrete per hour.
The DC 24 V battery module incorporates seven ProLogium SN-10 cells, delivering a capacity of up to 111.3 Ah in a compact form factor with high vibration resistance and flexible series/parallel configurations. It supports an operating voltage range of 29.4-17.5 V, and has an energy capacity of up to 2,671 Wh. Compared with existing lithium-ion solutions, the new battery module is expected to extend the MSD700’s operating time from 2 hours to 3.7 hours, while reducing charging time to approximately 27 minutes. For the NE100HBJ, operating time is expected to increase from 8 hours to 10 hours in travel duty and from 4 hours to 10 hours in crushing duty, with charging time should be reduce to 14 minutes.
