High-rate performance of all-solid-state lithium secondary batteries using Li4Ti5O12 electrode

Abstract The all-solid-state Li–In/Li 4 Ti 5 O 12 cell using the 80Li 2 S·20P 2 S 5 (mol%) solid electrolyte was assembled to investigate rate performances. It was difficult to obtain the stable performance at the charge current density of 3.8 mA cm −2 in the all-solid-state cell. In order to improve the rate performance, the pulverized Li 4 Ti 5 O 12 particles were applied to the all-solid-state cell, which retained the reversible capacity of about 90 mAh g −1 at 3.8 mA cm −2 . The 70Li 2 S·27P 2 S 5 ·3P 2 O 5 glass–ceramic, which exhibits the higher lithium ion conductivity than the 80Li 2 S·20P 2 S 5 solid electrolyte, was also used. The Li–In/70Li 2 S·27P 2 S 5 ·3P 2 O 5 glass–ceramic/pulverized Li 4 Ti 5 O 12 cell was charged at a current density higher than 3.8 mA cm −2 and showed the reversible capacity of about 30 mAh g −1 even at 10 mA cm −2 at room temperature.
