Abstract:
Olivine structured LiMPO4 (M = Fe, Mn, Co & Ni) nano particles are potential cathode materials for high power Li-ion batteries (>4V: Li+/Li). Unfortunately, LiMPO4 has low intrinsic electronic and ionic conductivity due to defect association effects, which have a strong impact on its transport properties [1].
In order to overcome the mentioned associated problems, several synthesis methods have been devised. Thus, nano size structured materials with different shapes were developed followed by surface engineering with electronically conducting materials like carbon, etc.
Several literature reports on pure and different carbon additives coated over LiMPO4 (M = Fe, Mn, etc.) nano particles showed significant improvement in their electrical and electrochemical properties [2-4]. Therefore, the present work is aimed to study the PVP assisted polyol and resin coating processes to produce pure and carbon coated LiMPO4 (M= Co & Ni) nanoparticles, referred as LiNiPO4/C & LiNiPO4/C, subject to characterization by XRD, SEM, TEM-EDS and Impedance spectroscopy techniques.
The detailed results will be presented and discussed.
