Understanding Graphene Batteries:
Graphene batteries, also known as graphene-based batteries, employ graphene or graphene-based materials in their construction. Graphene's outstanding characteristics, including its high electrical conductivity, large surface area, mechanical strength, and chemical stability, contribute to the superior performance of these batteries. Graphene batteries encompass various types such as graphene-enhanced lithium-ion batteries, graphene-sulfur batteries, graphene-air batteries, and more. The incorporation of graphene into battery systems unlocks a range of benefits, making them a promising alternative to traditional energy storage technologies.

Advantages of Graphene Batteries:
Graphene batteries offer several advantages over conventional battery technologies:
