Lithium batteries are better among graphene batteries and lithium batteries.
Graphene batteries are a battery technology based on the material graphene. Graphene is a single-layer, two-dimensional crystal structure formed by carbon atoms, with extremely high electrical and thermal conductivity and mechanical strength. Graphene batteries have the theoretical potential for high energy density, fast charge/discharge rates and long cycle life. They also have low internal resistance and high electrical conductivity, providing higher power output.
Lithium batteries are a battery technology based on lithium ion embedding/de-embedding reactions for charge and discharge. Li-ion batteries have been widely used in mobile devices, electric vehicles and renewable energy storage. Li-ion batteries have a high energy density and can provide long range and usage time. They also have a relatively stable cycle life and a more mature commercial production technology.
