In conclusion, the application of graphene in lithium-ion batteries has shown significant potential in improving battery performance. Graphene's exceptional electrical conductivity, high specific surface area, and excellent mechanical properties make it an ideal candidate for enhancing the capabilities of these batteries.
Conclusions Graphene forms a 3D electron conducting network in lithium ion battery cathode materials when mixed properly. This increases electron conductivity and therefore rate capability and cyclability of the materials. However, when mixed improperly or used in excessive amounts, it can sometimes impede lithium ion migration.
The graphene-based composites as a result often exhibit greatly improved specific capacities, rate capabilities, and cycling performance. The LIBs are frequently denoted to as 'rocking chair batteries' since they oscillate backwards and forwards between the electrodes when the battery is being charged or depleted.
The characterization of graphene used in studies researching it as an electron conducting additive for lithium ion battery cathode materials is often deficient. The importance of proper graphene preparation and characterization cannot be overlooked. The preparation of graphene with large electron conductivity is of paramount importance.
Therefore, various graphene-based electrodes have been developed for use in batteries. To fulfil the industrial demands of portable batteries, lightweight batteries that can be used in harsh conditions, such as those for electric vehicles, flying devices, transparent flexible devices, and touch screens, are required.
