Batteries enhanced with graphene can fix or mitigate many of these issues. Adding graphene to current lithium batteries can increase their capacity dramatically, help them charge quickly and safely, and make them last much longer before they need replacement. What Are Sodium-Ion Batteries, and Could They Replace Lithium?
Although solid-state graphene batteries are still years away, graphene-enhanced lithium batteries are already on the market. For example, you can buy one of Elecjet's Apollo batteries, which have graphene components that help enhance the lithium battery inside.
Few-layered graphene may have an important role in the progress of other battery chemistries. For example, an aluminium-ion battery was recently reported that can be fully charged in under one minute because of the ultrafast ion intercalation into 3D graphene foams 52. Ultrathin current collectors for lightweight devices.
The impact graphene can have on charging times is also likely to increase the adoption of electric cars in general. We’ve also developed some research at UCLA looking at biodegradable graphene batteries that could be employed for as a power source for implantable medical devices.
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.
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.
