Battery Application

LiCoO2is the commercial cathode material for Li-ion battery application with many advantages such as ease of preparation and good electrochemical properties. However, it has some limitations especially Co being expensive and toxic. Therefore, the substitution of Co in the LiCoO2by non-toxic and inexpensive transition metal elements will be an improvement. Partial substitution of Co by Mn has been done in this work via the self-propagating combustion (SPC) method. The materials are then characterized. The materials obtained were phase pure but the electrochemical discharge capacity is about 24 – 27 % less than that of LiCoO2. However, the cycling behaviour of LiCo0.9Mn0.1O2and LiCo0.8Mn0.2O2over 15 cycles improved over that of LiCoO2.

This review describes some recent developments in the composite doped cathode materials such as LiCoO2, LiNiO2, LiMn2O4, and LiMnO2 with focus on LiFePO4. Olivine LiFePO4 have attracted considerable attention since last decade because of its promising properties as a cathode material in Li ion based batteries (LIBs), that is, it offers high theoretical capacity, environmental friendliness, and less toxicity. The electrochemical and structural characterization of this system will be discussed in more detail as compared with its other counterpart.
