Development and Characterization of New Layered Cathode Materials for Lithium Ion Batteries

 

Lithium ion batteries are now widely used especially in mobile applications as a power source. In the case of Li-ion batteries, certain properties such as energy density, cycle life, safety, electrical conductivity and rate capability have great importance. LiCoO2 has been used as a cathode material for Li-ion batteries for many years. However, capacity of the currently used layered LiCoO2 cathodes is limited to perform 50% of its theoretical capacity (140 mAh/g). Further, one of the main ingredients of the compound, Co, has high cost and can be problematic considering toxicity issues. In this regard, novel layered Li(Ni1/3Mn1/3Co1/3)O2 cathode materials have been investigated as an alternative cathodes searching for higher capacity, cycle life, rate capability and safety.
