Best top 10 lithium battery graphene manufacturers in China

The evolution stage of lithium ion battery conductive agent is from zero-dimensional conductive agent carbon black material to one-dimensional fibrous structure carbon nanotube material, and then to two-dimensional sheet structure graphene material.

This article will introduce the conductive mechanism of the new two-dimensional structure graphene material, the production process and the top 10 lithium battery graphene manufacturers in China, including Ene-Carbon, Tunghsu Optoelectronic, Knano, LEADER NANO, The Sixth Element, HAOXIN TECH, MORSH, SuperC Technology, Carbonene and MORION.

1. Advantages of graphene as a conductive agent for lithium battery

Conductive agent materials are an important part of lithium-ion batteries including lifepo4 battery, ternary lithium battery, etc. and play an important role in the electrochemical performance of lithium-ion batteries. After an appropriate amount of conductive agent is added to the electrode, the electron transfer rate inside the electrode can be effectively improved.

Graphene has excellent mechanical and optical properties, high thermal conductivity, low resistivity, and strong stability. As a new lithium battery conductive agent, due to its unique sheet structure, the contact with the active material is in the form of point-surface contact.

In this way, the role of the conductive agent can be maximized, and the amount of the conductive agent can be reduced, so that more active materials can be used to increase the capacity of the lithium battery.
