Amorphous aluminum-based oxychloride superionic conductors via cation–oxygen coupled modification for durable high-rate all-solid-state lithium batteries

Local structural disorder induced by Zr/Hf and O 2− co-doping in Li 3 AlCl 6 yields amorphous Al-based electrolytes with greatly accelerated Li + migration and stable cell interfaces, supporting low-cost and long-life all-solid-state lithium batteries.
