Among various parts of LIBs, cathode material is heaviest component which account almost 41% of whole cell and also majorly decides the performance of battery.
It is well known that the energy density of lithium-ion batteries strongly depends on the specific capacities and working potentials of the anode and cathode. For the cathode materials such as Li–Co–O, Li–Mn–O, and olivine LiFePO 4 systems , , , , the specific capacity ranges from 130 to 200 mA hg −1.
However, the electrochemical specific capacity of LiC 6 (372 mA hg −1) is less than 10% that of the metallic lithium. To meet the increasing demand for higher energy and power densities, various lithium alloys and metal oxides are explored as new high-capacity anode materials for lithium ion batteries. 2.1. Lithium alloys
This study describes new and promising electrode materials, Li 3 NbO 4 -based electrode materials, which are used for high-energy rechargeable lithium batteries.
