Therefore, graphene is considered an attractive material for rechargeable lithium-ion batteries (LIBs), lithium-sulfur batteries (LSBs), and lithium-oxygen batteries (LOBs). In this comprehensive review, we emphasise the recent progress in the controllable synthesis, functionalisation, and role of graphene in rechargeable lithium batteries.
Emerging consumer electronics and electric vehicle technologies require advanced battery systems to enhance their portability and driving range, respectively. Therefore, graphene seems to be a great candidate material for application in high-energy-density/high-power-density batteries.
Furthermore, graphene has the capability to boost lightweight, durable, stable, and high-capacity electrochemical energy storage batteries with quick charging time. Graphene has the capability of charging smartphones with electricity in a short time.
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.
Graphene has the capability of charging smartphones with electricity in a short time. For example, the traditional lifecycle of LIBs can be enhanced, and they can be charged in a short time, stocking more power for a prolonged period.
There are also numerous academic research studies showing that using a graphene coating instead of a ceramic coating can improve the performance of lithium metal and lithium sulfur batteries [161, 162, 163, 164, 165, 166, 167, 168, 169, 170, 171].
