Customer ServiceThe 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.
As the negative electrode material of SIBs, the material has a long period of stability and a specific capacity of 673 mAh g −1 when the current density is 100 mAh g −1.
There are three main groups of negative electrode materials for Li-ion batteries. The materials known as insertion materials are Li-ion batteries' “historic” electrode materials. Carbon and titanates are the best known and most widely used.
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.
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.
The development of graphene-based negative electrodes with high efficiency and long-term recyclability for implementation in real-world SIBs remains a challenge. The working principle of LIBs, SIBs, PIBs, and other alkaline metal-ion batteries, and the ion storage mechanism of carbon materials are very similar.
