Electrode Property of Sintered Ceramic Based on CaMnO3 in LiOH Aqueous Solution

Abstract

Sintered ceramics of Ca0.9A0.1MnO3-δ(A = La, Nd, Sm, Gd and Y) were studied on their cathode properties in LiOHaq. solution. After firing, the samples were obtained as high conductivity sintered (porous) materials composed of an orthorhombic perovskite-type phase. Next, charge discharge performances of the electrodes consisting of the sintered sample were investigated. The discharge capacity of Ca0.9Y0.1MnO3-δwas 185 mAh·g-1on the 1st cycling, and the 1st charging was possible by 130 mAh·g-1. However, the 2nd discharge capacity remarkably decreased to lower than 50 mAh·g-1. Considering no obvious charging property on the previous La-substituted sample of Ca0.9La0.1MnO3-δ, it would mean that change of the substituent for CaMnO3 affects the electrochemical property. The roll of lithium ions, the effect of the cut-off potential range on the cycle performance would be discussed leading to the charge/discharge results of the cell (-)Zn/LiOHaq./Ca0.9Y0.1MnO3-δ(+).
