Graphene-based batteries represent a revolutionary leap forward, addressing many of the shortcomings of lithium-ion batteries. These batteries conduct electricity much faster than conventional battery materials, offer a higher energy density, and charge faster because of Graphene.
When utilized directly as anode materials for lithium-ion batteries, graphene materials are prone to aggregating and lack the benefit of lithium storage. As a result, composites based on graphene perform electrochemically better than single component materials when used as anode materials for lithium-ion batteries.
