Factors influencing Li+ migration in garnet-type ceramic electrolytes

Garnet-type ceramic electrolyte with exceptionally high Li+ conductivity has attracted wide interests for the development of safe electrochemical devices. However, the factors affecting the ionic migration still deserve more attentions. In this study, five garnet-types ceramic electrolyte were chosen to investigate the factors. The thermal behavior of garnet-type electrolyte during sintering was studied to achieve high conductivity. The electrochemical properties are correlated with crystal structure, migrating route and lattice parameters. Nine influening factors were discussed to analyze the ionic migration in garnet-type ceramic electrolyte. (C) 2018 The Chinese Ceramic Society. Production and hosting by Elsevier B.V.
