Improvement of the Li-ion conductivity and air stability of the Ta-doped Li7La3Zr2O12 electrolyte via Ga co-doping and its application in Li–S batteries

The co-doping of Ga in LLZT has expedited the densification of the garnet electrolyte, leading to a reduction in the sintering temperature required for densification and an enhancement in the stability of the electrolyte.
