Fabrication of all-solid-state lithium ion battery using ceramic-hybrid polymer electrolyte

Abstract

Our previous researches on all solid-state Li polymer battery showed stable cyclic durability more than 150 cycles, while severe degradation was followed. This phenomenon would be due to electrolysis of anion in Li salt and poor mechanical property of polymer electrolyte film. To improve mechanical characteristics and suppression of net anion conductivity, all-solid-state lithium ion battery was fabricated by using ceramic-hybrid polymer electrolyte in which solid-state polymer electrolyte was intercalated in the mesoporous silica. Electrochemical tests for assembled cell showed improvement of cyclic durability and increase in transport number of Li+.
