Polish central bank governor Glapinski said the country's gold reserves rose to 613 tonnes.

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.
