LiMnPO4 cathode material and its derivatives are promising for energy-storage devices owing to environmental friendliness, high energy density, structural stability. Olivine is attractive due operating voltage (4 5 V vs. Li+/Li), strong P-O covalent bond, which offers many safety advantages. Despite these advantages, the commercialization of LiMnPO4-based lithium-ion batteries (LIB) has been plagued by other factors such as poor electronic ionic conductivity, a surface barrier Li-ion diffusion, degradation induced Jahn-Teller effect. Various strategies, including transition metal doping at A-site fabrication heterostructures with electron mobility, have employed address challenges. Notably, exceptional electrode performance microrods may be ascribed their distinct three-dimensional porous hierarchical structure, promotes rapid Li+ transport kinetics improves stability in reversible electrochemical reactions. While enhancement techniques centered on processing, solid-state chemistry more effective, offering convenience overcoming obstacles related physiochemical performance. The synthesis approach, typically known capability tailor size morphology materials, demonstrated significant impact enhancing activity LiMnPO4. This review critically discusses structure dependence It gives broad overview research approaches being enhance through technique. also provides comprehensive challenges need further fully realize potential cathodes Li-Ion batteries.
