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.
Besides technical requirements, such as redox activity and suitable electronic and ionic conductivity, and sustainability aspects (cost, toxicity, abundance, ...), there is a myriad of practical parameters related to the stringent operation requirements of batteries as chemical energy storage devices which need to be considered at an early stage.
Current research appears to focus on negative electrodes for high-energy systems that will be discussed in this review with a particular focus on C, Si, and P.
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.
Lithium (Li) metal shows promise as a negative electrode for high-energy-density batteries, but challenges like dendritic Li deposits and low Coulombic efficiency hinder its widespread large-scale adoption.
