Abstract
Continuous evolution of electrode materials still has not correspond today’s energy storage system necessity and limits their application range. Numerous approaches are proposed to improve lithium ion
batteries (LIBs) energy density including advancement of positive electrode materials. Olivine structured
cathodes as LiCoPO4 and LiNiPO4 are excellent candidates due to their working potentials of exceeding 5.0 V
vs. Li+
/Li. Despite the efforts, these materials still have several intrinsic problems which demand various
strategies to overcome. The paper systematically reviews the recent progress of these cathode materials.
The approaches based on particle size manipulation via synthesis route variation and carbon addition,
surface modification by coating with electron conducting carbon layer, and doping the structure with other
metal ions were discussed and analyzed as the most impactful towards achieving competitive performance.
Furthermore, the computational technique was discussed due to its importance in understanding and
designing the materials from atomic to microscale levels. The potential applications of these cathodes in a
new generation of all-solid-state Li-ion and aqueous batteries were described.
