Ni-Doped Li1.15Mn2-xNixO4 as Cathode Material for Lithium-Ion Battery
In this work, spinel Li1.15Mn2−xNixO4 cathode material for lithium ion battery was prepared by a coprecipita- tion method, and the material was modified by doping different contents of Ni. The crystal structure was determined from the X-ray diffraction pattern, and the morphology was observed by scanning electron microscopy. The electro- chemical properties of the product were studied by galvanostatic charge-discharge measurement. The results showed that Li1.15Mn2−xNixO4 displayed better electrochemical property. Its initial discharge specific capacity was 115.9 mAh·g−1 at the room temperature and the specific capacity retention ratio was 85% after 26 cycles at a rate of 0.1 C.
