In recent years, Li-rich layered cathode materials have caught more and more attention; however, their low-temperature performance have hardly been researched and reported. In this work, typical layered Li-rich oxides (0.55Li2MnO3·0.45LiNi1/3Co1/3Mn1/3O2) are successfully synthesized by co-precipitation method. And their electrochemical properties have been investigated emphatically at 25°C and 0°C...
Spherical lithium-excess high manganese layered oxides, Li1.8[Mn0.7Co0.15Ni0.15]O2.675, were successfully synthesized by carbonate co-precipitation method. To further improve the electrochemical performance of this cathode materials, spherical Li1.8[Mn0.7Co0.15Ni0.15]O2.675 particles were functionally modified with fast Li+-ion conductor Li2SiO3 via a sol-gel method. The structural change features...
