Porous SiOx electrodes synthesized via radiofrequency sputtering fixes durability issues in all-solid-state lithium batteries

"overcomes low durability (the negative Si electrode repeatedly expands contracts), replaces toxic liquid electrolyte with Li-La-Zr-Ta-O solid electrolyte... much better cycling, enables SiOx films as thick as 5 µm massively boosting space efficiency/ energy density of the negative electrode 17X higher"
