摘要:
Cathode materials having an improved electronic conductivity allowing for faster kinetics in the electrochemical reaction, as well as higher conductivity to meet the power requirements for many consumer applications, especially at low temperatures. The cathode material comprises a compound from the family of compounds where the basic unit is generally represented by LixNi0.5TiOPO4. The structure of LixNi0.5TiOPO4 includes corner sharing octahedra [TiO6] running along the C-axis. The structure is such that nearly three Li atoms are being inserted in LixNi0.5TiOPO4. A cell in accordance with the principles of the present invention is rechargable and demonstrates a high capacity of lithium intercalation and fast kinetics.
