Compared to conventional batteries, graphene batteries have better energy storage and faster charging times. While lithium-ion batteries have powered our devices and electric vehicles (EVs) for decades, they face significant limitations—limited energy density, safety risks, and long charging. . Hydrograph's chief scientist shows how the properties of this amazing material, graphene, enhance Li-ion, Li-air, and Li-sulfur battery capabilities. Hydrograph's Hyperion System for producing graphene (left). Graphene's. . Graphene's atom-thick 2D lattice of carbon atoms gives it exceptional physical properties that benefit energy storage. For example, pristine graphene has a huge theoretical specific surface area (~2600 m 2 /g) and ultrahigh thermal/electrical conductivity (thousands of W/m·K).
