Title:
ELECTRICITY STORAGE DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/175213
Kind Code:
A1
Abstract:
Ceramic particles constituting a ceramic layer that serves as a separator in this electricity storage device are selected from among ceramics that can undergo electrochemical oxidation in an organic electrolyte solution. Ceramic particles in contact with a negative electrode thus remain electronically insulating while the remaining ceramic particles are electrochemically oxidized and acquire ionic conductivity, keeping internal resistance in this electricity storage device low despite the use of a ceramic layer as a separator.
