Synthesis of LiCo_xMn_2-xO₄ by Low Temperature Solid-State Reaction for Cathode Material

Abstract:

LiCo_xMn_2-xO₄ can serve as one of the main candidates for cathode materials for lithium batteries since they are abundant, low cost and environmentally friendly. This study aims to study the synthesis of LiCo_xMn_2-xO₄ by low temperature solid-state reaction and its microstructure determination. Attention is paid more to the mole ratio of Co/Mn in LiCo_xMn_2-xO₄. The compound was characterized by XRD, SEM-EDX, and BET while the analysis of LiCo_xMn_2-xO₄ microstructure was carried out by Direct Method using winPLOTR package program and Diamond using XRD data. The series of LiCo_xMn_2-xO₄ have well–developed cubic crystal structure with Fd3m phase, and the increase in the dopant does not change its structure. The lattice parameters and cell volumes of LiCo_xMn_2-xO₄tend to decrease with the increase in x values
