Preparation of High Voltage Spinel LiNi_0.5Mn_1.5O₄ Cathode Material Using Polymer-Assisted Co-Precipitation Procedure

Abstract:

Cathode material LiNi_0.5Mn_1.5O₄was synthesized via oxalate co-precipitation process using LiCl,NiCl₂·6H₂O and MnCl₂·4H₂O as raw materials, oxalate as precipitant. The effects of calcining temperature and polymer-assisted during the synthetic process on the performance of the products were analyzed. When calcining at 700°C for 10h and with assistance of polyacrylic acid as dispersive, the synthesized product had cubic spinel structure, uniform particle size and the aggregations of particle was reduced.
