To the best of our knowledge, complete, graphene-based, lithium ion batteries having performances comparable with those offered by the present technology are rarely reported; hence, we believe that the results disclosed in this work may open up new opportunities for exploiting graphene in the lithium-ion battery science and development.
But interestingly, due to the high surface energy of graphene, GN will also agglomerate during the cycle of lithium-ion battery, the aggregation and re-stacking between individual graphene flakes driven by strong π–π bonds, makes GN’s behavior closer to graphite, and this problem has been to be solved [128, 129, 130, 131].
There have been a lot of discussions on graphene-composite lithium iron phosphate (LFP/G) materials. It is well known that the easiest way to prepare LFP/G is undoubtedly the mechanical mixing method. The most common methods of mechanical mixing include ultrasonic treatment and mechanical ball milling.
The specific capacity of an important commercial cathode material, lithium iron phosphate, is much lower than its theoretical value. Hu et al. report that incorporation of electrochemically exfoliated graphene layers in a carbon coating improves capacity beyond that predicted by theory.
