Abstract

The influence of the initial addition of Pt on the microstructure and electrochemical properties of synthesized LiCoO₂-based material was investigated. A small amount of Pt additive induces Li₂PtO₃ and Pt in matrix LiCoO₂ to form a multi-phase composite. This multi-phase composite shows the improved rate performance and cycleability at high rate in comparison with the single-phase of LiCoO₂. This behavior is attributed to the enhanced diffusion of Li ion in the LiCoO₂ matrix, which can be demonstrated by galvanostatic intermittent titration technique.
