The Research of LMO Lithium Battery Preparation Process Optimization

The author tells of the electrical property of LMO lithium ion batteries,by using the same LMO material,with different cathode materials and electrolytes.The result shows that the electrical property of the battery is not only the subject to anode material,but also the cathode,including electrolyte and the formation system.When the DMLM-12 LMO material of CITIC Dameng Mining Industries Limited is formed with a battery with HP-1 cathode material,LBS electrolytes,and the formation system is 0.05 C,with current rate charge 180 min,then 0.3 C with current rate charge 60 min.The battery shows that electrical property as the discharge capacity is 108.3 mAh/g,the 50th cycle capacity fading rate is only-4.31%.
