[Solid-state: ProLogium starts mass production of Gen 3.5 all-solid-state cells at 381 Wh/kg]
ProLogium announced on Sept 2 that its third-generation Gen 3.5 lithium ceramic battery has entered mass production at its gigawatt-scale plant in Taiwan, China, moving high-energy-density all-solid-state technology from pilot stage to scaled output. TÜV tests show its 185.4Ah large cell reaches 381 Wh/kg and 903 Wh/L, and UL Solutions testing under Chinese standard GB/T 43568-2026 confirms its all-solid-state classification. ProLogium has shipped over 2.4 million cells since 2013 and won 175+ repeat orders in automotive use; its next-gen Gen 4 battery requires only about 10% retrofit of existing lines, targeting AI data centers, EVs, maritime and aerospace.
