It should be noted that too much graphene does not help because of its low packing density, which can reduce the energy density of the battery. It is thus advisable to reduce the amount of graphene in the hybrid electrodes while maintaining good electrochemical performance.
Graphene is an essential component of Nanotech Energy batteries. We take advantage of its qualities to improve the performance of standard lithium-ion batteries. In comparison to copper, it’s up to 70% more conductive at room temperature, which allows for efficient electron transfer during operation of the battery.
Researchers have shown that it is possible to fabricate such batteries by replacing the graphite anodes used in today's LIBs with graphene electrodes in the form of folded graphene paper 68, porous graphene films 69 and solvated graphene frameworks 70.
However, they suffer from long recharge times (typically hours), whereas battery users are looking for a battery that recharges in minutes or even seconds. The use of graphene allows faster electron and ion transport in the electrodes, which controls the speed over which the battery can be charged and discharged.
However, in most cases, large amounts of graphene (10–20% w/w) are normally used in these hybrid electrodes. It should be noted that too much graphene does not help because of its low packing density, which can reduce the energy density of the battery.
