Nanoporous ZnGa2O4-modified separator as a multifunctional polysulphide barrier for advanced lithium-sulfur batteries

Zifan Ivan Wang, Wensi Li, Tianzhen Wang, Mingyuan Pang et autres

Nanoporous ZnGa 2 O 4 was synthesised as a separator modifier for lithium‑sulfur batteries via a one-step sol-gel process followed by high-temperature calcination. The modified separator could effectively adsorb and catalyse lithium polysulphides, thus inhibiting the shuttle effect and improving their redox …
