Investigation of the Overlithiation of Layered LiNi_0.7Co_0.2Fe_0.1O₂ Material

Abstract:

The purpose of this research was to investigate and compare the electrochemical characterization of new cathode materials LiNi0.7Co0.2Fe0.1O2 and Li1.1Ni0.6Co0.2Fe0.1O2. The materials were prepared using a combustion synthesis method. Composite cathodes were fabricated and assembled in a coin-type cell. The discharge profile showed plateaus at 3.7 V and 1.6 V. The overlithiated sample exhibited a 10.4% increase of discharge capacity in the first cycle of and an increase of 43.7% in the 5th cycle compared to the non-overlithiated sample.
