Title:
ALL-SOLID-STATE BATTERY AND METHOD OF MANUFACTURING ALL-SOLID-STATE BATTERY
Document Type and Number:
WIPO Patent Application WO/2024/034629
Kind Code:
A1
Abstract:
Provided is an all-solid-state battery in which cycling-performance degradation due to increase in interfacial resistance during charging/discharging is kept under control. An all-solid-state battery 10 is charged and discharged by a conversion reaction, and includes: a positive electrode layer 11 containing a positive electrode active material; a negative electrode layer 12 containing a negative electrode active material; and a solid electrolyte layer 13 containing a solid electrolyte and formed between the positive electrode layer 11 and the negative electrode layer 12. The absolute value of the difference [(Ep)−(En)] between the percent actual expansion (Ep) of the positive electrode layer 11 computed with formula (1), and the percent actual expansion (En) of the negative electrode layer 12 computed with formula (2) is 10% or less. Formula (1): Positive electrode layer percent actual expansion (Ep) = positive electrode layer expansion rate × positive electrode layer percent thickness
Formula (2): Negative electrode layer percent actual expansion (En) = negative electrode layer expansion rate × negative electrode layer percent thickness
