摘要
LiNi0.5Mn1.5O4 is an attractive choice for a high-voltage positive electrode material for all-solid-state batteries. However, its use in all-solid-state batteries is challenging because of low ionic conductivity. In this study, we synthesized new amorphous electrode materials from LiMn1.5Ni0.5O4 and lithium oxyacid salts. The synthesized amorphous electrodes exhibited higher ionic conductivity and capacity than a LiMn1.5Ni0.5O4 crystal in both liquid- and solid-type cells. Among these electrodes, amorphous 80LiMn1.5Ni0.5O4·20Li3PO4 (mol %) demonstrated a high reversible capacity of 220 mAh g−1 in a liquid-type cell. Amorphous electrode materials were prepared from LiMn1.5Ni0.5O4 and lithium oxyacid salts.
