Three million graphene sheets stacked to form graphite would be only one millimetre thick.


Graphene supercapacitors are among the possible applications.

Graphene Batteries

1. Internal Structure

The internal structure of a graphene battery is quite similar to that of a standard lithium-ion battery pack. There are 2 electrodes and an electrolyte solution to enable flow of charge. The difference is that one of the electrodes in graphene-based batteries, mostly the cathode, is replaced with a hybrid composite material (solid-state metal + graphene) used in place of a standard solid-state metal[7]

2. Advantages

Smaller, slimmer battery: Graphene being a two-dimensional material is only a single layer of atoms. To help understand this better, when you stack 3 million layers of graphene is that you get 1 mm thickness. This means that graphene would allow smartphones to be slimmer than ever and provide more space from additional electronics and allow to place higher capacity batteries.[8]

Higher capacity: Graphene has a higher energy capacity for the same size as compared to lithium-ion batteries. While Lithium-ion batteries are known to store up to 180 Wh per kilogram, graphene based batteries capable of storing up to 1,000 Wh per kilogram. So, the same size of graphene battery pack has a higher charge capacity than lithium-ion or other commonly used batteries.[8]

Faster charging times: Graphene is an excellent conductor of electricity. Its two-dimensional honeycomb structure doesn’t offer any resistance to the flow of electrons. So, it can charge quickly and also provide greater endurance compared to lithium ion batteries.[7]

Graphene patents

The invention of graphene has led to many patents for its practical application.[9] In 2013 the score was:

  1. Chinese entities: 2,204
  2. US entities: 1,754
  3. South Korean entities: 1,160
  4. United Kingdom entities: 54

South Korean electronics giant Samsung stands out as the company with most graphene patents to its name.[9]
