Ideally, the specific capacity of a negative electrode material should be higher than 372 mA h g –1, that is, the specific capacity of graphite, which is the most commonly used negative electrode material at present.
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.
In commonly used batteries, the negative electrode is graphite with a specific electrochemical capacity of 370 mA h/g and an average operating potential of 0.1 V with respect to Li/Li +. There are a large number of anode materials with higher theoretical capacity that could replace graphite in the future.
