How to make graphene:
First, pour some graphite powder into a blender. Add water and dishwashing liquid, and mix at high speed. Congratulations, you just made the wonder material graphene. This surprisingly simple recipe is now the easiest way to mass-produce pure graphene – sheets of carbon just one atom thick.
Highlights
•The use of graphene in lithium ion battery cathode materials has been reviewed.
•Graphene improves electron conductivity of lithium ion battery cathode materials.
•Graphene nanosheets form an electron conducting network within the cathode.
•Graphene composite cathodes have superior rate capability and cyclability.
Abstract
Graphene is a relatively new and promising material, displaying a unique array of physical and chemical properties. Although considered to be especially promising for the use in energy storage applications, graphene has only recently been implemented as an electron conducting additive for lithium ion battery cathode materials. In current studies graphene is found to significantly improve cathode electrochemical performance. As the charge capacity, rate capability and cyclability of lithium ion batteries are still in ever-remaining need of improvement, this article examines the prospects of graphene implementation into lithium ion battery cathodes to meet such demands. The existing literature and recent advances on the topic have been reviewed, covering the preparation of graphene and graphene composite lithium ion battery cathodes, their structure and electrochemical properties along with underlying principles for electrochemical performance enhancement of such materials.
