WebHigher capacity: Graphene has a higher energy density as compared to lithium-ion batteries. Where the latter is known to store up to 180 Wh per kilogram, graphene’s capable of storing up to 1,000 Wh per kilogram. So, you can have a higher capacity graphene battery pack of the same size as the lithium-ion battery. Web1 aug. 2024 · The rechargeable battery systems with lithium anodes offer the most promising theoretical energy density due to the relatively small elemental weight and the larger Gibbs free energy, such as Li–S (2654 Wh kg −1), Li–O 2 (5216.9 Wh kg −1), Li–V 2 O 5 (1532.6 Wh kg −1), Li–FeF 3 (1644 Wh kg −1), etc.
