What role does graphite products play in hydrogen energy vehicle batteries?

Graphite products plays several roles in hydrogen energy vehicle batteries:

1. Can be used as a negative electrode material: Graphite products is commonly used as one of the main materials for the negative electrode in hydrogen energy vehicle batteries. In the battery, the negative electrode material receives electrons from the external circuit while absorbing ions from the positive electrode. Graphite products's high conductivity and good chemical stability make it an ideal negative electrode material.

2. Can be used as a protective layer: Graphite products can be used as a protective layer material for the negative electrode in hydrogen energy vehicle batteries, preventing direct contact between the electrolyte in the battery and the negative electrode material. This helps prevent the oxidation and corrosion of the negative electrode material, thereby extending the battery's lifespan.

3. Can be used as a conductive filler: Graphite products can also be used as a conductive filler in the positive electrode material of the battery. In certain types of hydrogen energy vehicle batteries, the positive electrode material is typically a sodium or potassium ion exchange resin. Graphite products can be added to the positive electrode material to enhance its conductivity.

Overall, graphite products plays an important role in hydrogen energy vehicle batteries by enabling efficient electron transfer, protecting the negative electrode materials, and prolonging the battery's lifespan.
