Graphene based Anode

The objective of the study is to conduct a state of art search related to the Graphene based anode of Lithium-ion Batteries.

Global attention to electric vehicles and renewable energy storage drives the research for novel anode materials in lithium-ion batteries (LIBs). Due to the unique two-dimensional structure, facile modulation of architecture and defects, and great compatibility with other materials, graphene-based materials including graphene and its nanocomposites have been intensively investigated as potential anode materials.

In lithium-ion batteries, lithium ions move from the negative electrode to the positive electrode during discharge, and this is reversed during the charging process. One of the potential solutions to these problems is to develop new electrode materials for lithium-ion batteries. Graphene, a miracle material, is chemically stable and has high electrical conductivity. So it has naturally been considered a suitable electrode alternative in battery applications.

What makes graphene ideal?
  • High thermal & electrical conductivity
  • High elasticity, flexibility & Hardness.
  • High resistance. Graphene is approximately 200 times stronger than steel, similar to diamond resistance, but much lighter.
  • Ionizing radiation is not affected
  • Low Joule effect, heating when conducting electrons.
  • Able to generate electricity by exposure to sunlight
  • The high density doesn’t let Helium atoms pass, but it does allow the passage of water, which evaporates at the same speed as if it were in an open container.
  • Low electricity consumption compared to other compounds
  • Transparent material

This study aims to look into every aspect of the use of graphene as an anode.
