1. The storage capacity is different: the specific energy of a lithium battery (subject to the most advanced) is 180wh/kg, while the specific energy of a graphene battery is more than 600wh/kg.

　　2. Different service life: The service life of graphene is twice that of lithium battery, and it is more durable than lithium battery under high temperature.

　　3. Industrialized mass production: graphene battery has not been industrialized mass production yet.

　　The biggest disadvantage of lithium battery is its poor safety. Although the probability of explosion is low, it is dangerous as long as the possibility of explosion exists. However, it is lighter in weight and smaller in volume, so it is lighter and more durable than lead-acid battery. It can be used for 3-5 years and can be charged and discharged for 2000 times.

　　Because of its unique characteristics, graphene is called "magic material", and scientists even predict that it will "completely change the 21st century". Professor Colin Bailey, Vice President of the University of Manchester, said: "Graphene has the potential to revolutionize a large number of applications, from smart phones and ultra high-speed broadband to drug delivery and computer chips."

　　The technology of graphene battery is not mature enough, and its quality is uneven, but its advantages are good power storage, light weight and high durability.
