The energy density of graphene batteries is significantly higher than that of lithium-ion batteries. Graphene batteries can potentially store up to 1000 Wh per kilogram, while lithium-ion batteries typically store around 180-250 Wh per kilogram. This means graphene batteries can store more energy per unit of weight, making them ideal for applications requiring compact and lightweight power sources, such as electric vehicles and portable devices.
However, it’s essential to note that graphene batteries are not yet widely commercialized due to cost and manufacturing challenges. When graphene is integrated into lithium-ion batteries, it can enhance their energy density, charging speed, and lifespan. For example, using graphene with silicon anodes in lithium-ion batteries can nearly double the volumetric energy density compared to standard lithium-ion batteries.
