For lithium-ion batteries, the most in-depth studied material for the cathode is cobalt oxides and lithiated nickel. The high stability of structure characterizes both of them. They are expensive and difficult to make as the resources are limited. In the development of these layered compounds’ solid solutions, there is a resolution.
The limitations in potential for the electroactive material of the negative electrode are less important than in the past thanks to the advent of 5 V electrode materials for the cathode in lithium-cell batteries.

The electrochemical reaction at the negative electrode in Li-ion batteries is represented by x Li + +6 C +x e − → Li x C 6 The Li + -ions in the electrolyte enter between the layer planes of graphite during charge (intercalation). The distance between the graphite layer planes expands by about 10% to accommodate the Li + -ions.
Lithium alloyed metals and carbon (graphite)-based materials are the two most used anode materials today. Oxide spinel Li4Ti5o12 is a commercialized lithium alloyed metal. For avoiding the issues in safety and cycling, like the formation of dendrite on anodes of lithium, the usage of minimal potential intercalation electrode is advisable.
Lithium manganese spinel oxide and the olivine LiFePO 4 , are the most promising candidates up to now. These materials have interesting electrochemical reactions in the 3–4 V region which can be useful when combined with a negative electrode of potential sufficiently close to lithium.
