HuiNeng announces mass production of lithium ceramic all-solid-state batteries with 381 Wh/kg
HuiNeng announced that its Gen 3.5 lithium ceramic all-solid-state battery has been mass-produced on the island’s Giga-level industrial platform. This battery cell achieves a mass energy density of 381 Wh/kg and a volume energy density of 903 Wh/L. After being placed in a vacuum environment at 120°C for 6 hours, its weight loss rate is less than 0.05%. Its Logithium cell architecture uses ceramic separators combined with special material edge binders to create an additional isolation structure beyond the separation of positive and negative electrodes, covering potential burrs at the electrode edges and serving both sealing and insulation functions. In the future, HuiNeng plans to use a fully inorganic superfluid electrolyte system in its Gen 4 lithium ceramic batteries and introduce an active safety mechanism that can actively passivate active materials at high temperatures, achieving “zero thermal runaway”. At the same time, it will enhance low-temperature performance, improve material and manufacturing cost competitiveness, and expand the range of applications.
