The olivine-type high-voltage cathode material LiCoPO
4 is a promising candidate for next-generation lithium-ion batteries, but generally exhibits low capacities and poor cycle life. This thesis presents simple and fast microwave-assisted solvothermal synthesis pathways towards particle size- and morphology-tuned LiCoPO
4 materials with cutting-edge electrochemical performances. In addition, the structure–property relationships of metastable, non-olivine LiCoPO
4 polymorphs and two novel mixed-valent Co(II,III) phases are investigated.
