Langu New Energy has started production at a 10,000-tonne-per-year oxide solid
electrolyte line in Liyang, the first domestic scale-up of oxide
solid-electrolyte capacity from the prior hundreds-of-tonnes level to ~10ktpa.
Domestic oxide solid electrolyte capacity had been stuck at the
hundreds-of-tonnes scale, with poor process stability, low yields and high costs
limiting downstream battery makers' ability to mass-produce. As semi-solid
batteries enter small-batch vehicle validation and solid-state batteries
approach mass production, a materials supply gap is emerging. Oxide solid
electrolytes are viewed as among the most commercializable core materials:
applicable to current solid–liquid hybrid cells to improve safety and
electrochemical performance, and able to be compounded with polymers into
composite solid electrolytes for solid-state systems.
