Graphene Based Futuristic Green Batteries For Energy Harvesting

The depleting fossil fuels coupled with increasing per capita energy consumption necessitate the scientific community to explore newer recyclable sources of energy harvesting for powering the myriad electrically fed appliances. Graphene is touted to be a material of immense promise in the design of rechargeable batteries of futuristic vision, and hence the need to concisely consolidate the present status of these next generation batteries has been felt. Graphene may be used directly for electrodes, as well as in tandem with other materials for battery applications; due to its excellent intrinsic electrical conductivity, thermal conductivity as well as very high surface area; which result in the enhancement of battery parameters of interest like power density, energy density, thermal management, battery lifetime and compactness. Herein we have consolidated the role of graphene in electrodes of Li-ion batteries, Li-air batteries, as well as flexible graphene-based batteries. This consolidation will serve in optimal design of batteries which are very important for powering multiple utilities.
