The performance of the cathode material directly affects the performance of a lithium-ion battery. Lithium cobalt oxide, lithium manganate, lithium iron phosphate, and ternary materials (polymers of nickel, cobalt, and manganese) are the most commonly used materials for the cathode.
In a lithium-ion battery, the anode is the “negative” or “reducing” electrode that provides a source of electrons. Classically, anode materials are made of graphite, carbon-based materials, or metal oxides, which are called intercalation-type anodes.
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. However, to maintain cell voltage, a deep study of new electrolyte–solvent combinations is required.
