Abstract

A type of rocking chair Li-ion battery was reported using 0.5Ag:V 2 O 5 composite films with and without lithiation as anode and cathode materials, respectively. The discharge capacity can reach 22 μAh/μm cm 2 with low capacity fading up to 100 cycles at a current of 10 μA/cm 2 . An all-solid-state lithium battery of Li/LiPON/0.5Ag:V 2 O 5 exhibited a typical reversible capacity of 42-72 μAh/μm cm 2 and the reduction of capacity is about 1.1% every cycle. These results suggest that a composite 0.5Ag:V 2 O 5 thin-film electrode is a promising cathode material for all-solid-state thin-film rechargeable lithium batteries.
