Abstract

Novel solid-state PEO rechargeable lithium cells based on the LiNi_0.8Co_0.2O₂ cathode and the SnSb-Li_2.6Co_0.4N composite anode have been developed for the high reliability exclusive of metallic lithium and the large energy density at 110 Wh Kg^-1. Electrochemical behavior of the cells demonstrates strong reliance dependent on the anode preparations. In view of the relatively low lithium ion diffusion, current density plays a significantly role upon the capacity and the retention of the composite anode. A cell design with good sealing and compacting configuration, as well as an appropriate thickness of electrolyte and electrode, results in a comparable cycling performance.
