Key Points

To examine how stacking pressure affects mechanical failure in Ni-rich cathodes of sulfide solid-state batteries.
Analysis of stacking pressure effects on ion transport and mechanical integrity in solid-state batteries.
Optimal stacking pressure improves ion transport and contact between materials.
Excessive stacking pressure leads to mechanical failure, including electrode cracking and capacity reduction.

Abstract

Stacking pressure in sulfide all-solid-state batteries has dual effects: optimal pressure improves contact and ion transport, while excessive pressure induces structural degradation, leading to electrode cracking and capacity fade.
