Interfacial architecture for extra Li⁺ storage in all-solid-state lithium batteries.

The performance of nanocomposite electrodes prepared by controlled ball-milling of TiS₂ and a Li₂S-P₂S₅ solid electrolyte (SE) for all-solid-state lithium batteries is investigated, focusing on the evolution of the microstructure. Compared to the manually mixed electrodes, the ball-milled electrodes exhibit abnormally increased first-charge capacities of 416 mA h g(-1) and 837 mA h g(-1) in the voltage ranges 1.5-3.
