The purpose of this study is to research and develop LiMnO$_2$-organic and Li$_{0.3}$MnO$_{2}$-organic composite with high energy density for Lithium ion polymer battery. This paper describes cyclic voltammetry, impedance sepctroscopy, electrochemical properties of LiMnO$_2$-organic and Li$_{0.3}$MnO$_{2}$-organic composite with polymer electrolyte as a function of a mixed ratio. The first discharge capacity of LiMnO$_2$-PAn with 3 wt.% PAn was 83mHA/g, while that of Li$_{0.3}$MnO$_{2}$-PPy composite was 136 mAh/g. The Ah efficiency was above 98% after the 2nd cycle. The LiMnO$_2$-PAn with DMcT 2 wt.% and Li$_{0.3}$MnO$_{2}$-PPy composites cathode with 5wt. PPy in PVDF-PC-EC-LiClO$_4$ electrolyte showed good capaity with cycling. The discharge capacity of LiMnO$_2$-PAn with wt.% DMcT was 80 and 130 mAh/g at 1st and 12th cycle, respectively. The capacity of LiMnO$_2$-PAn composite with 2 wt.% DMcT was higher than that of LiMnO$_2$-PAn composite.mposite.
