The negative electrode material is the main body of lithium ion battery to store lithium, so that lithium ions are inserted and extracted during the charging and discharging process.
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.
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.
This paper sheds light on negative electrode materials for Na-ion batteries: carbonaceous materials, oxides/phosphates (as sodium insertion materials), sodium alloy/compounds and so on. These electrode materials have different reaction mechanisms for electrochemical sodiation/desodiation processes.
For example, silicon-based materials, alloy materials, tin-gold materials, and the like. The negative electrode of lithium ion battery is made of negative electrode active material carbon material or non-carbon material, binder and additive to make paste glue, which is evenly spread on both sides of copper foil, dried and rolled.
In the case of both LIBs and NIBs, there is still room for enhancing the energy density and rate performance of these batteries. So, the research of new materials is crucial. In order to achieve this in LIBs, high theoretical specific capacity materials, such as Si or P can be suitable candidates for negative electrodes.
