Garnet solid-state electrolyte with benzenedithiolate catholyte for rechargeable lithium batteries

Abstract

A solid-state electrolyte, Li_6.4La₃Zr_1.4Ta_0.6O₁₂ (LLZTO), is used to block the crossover of lithium 1,2-benzenedithiolate (LBDT) in the catholyte to the lithium metal anode in a rechargeable lithium battery. The cell maintains a relatively stable cycle life (65.6% capacity retention after 100 cycles). The density functional theory simulation confirms that LBDT has strong interaction with LLZTO, which is helpful for reducing the interfacial resistance.
