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

A solid-state electrolyte, Li6.4La3Zr1.4Ta0.6O12 (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.
