New graphene ball batteries have been developed in South Korea.

According to South Korea "central daily" report, Samsung electronics integrated technology research team developed a new success battery material "graphene ball", than existing lithium ion batteries45% higher than that of charge capacity, charging speed increased by more than 5 times. The results of research and development, published online in the journal nature communications.

The researchers found that in high strength and high conductivity of graphene materials after adding silica, can be a lot of graphene synthesis, synthesis of graphene like popcorn presents a three-dimensional shape, so called "graphene ball", this kind of graphene anode materials for lithium ion battery protective film and cathode materials can improve after charging capacity and shorten the charging time, and high temperature stability can also be guaranteed.

Graphene in a new generation of material has long been regarded as typical material. Graphene from graphite strip are thin membrane carbon atoms, is characterized by high stability of the physicoehemical properties. The material is 100 times higher than the conductivity of copper; More than 140 times higher than silicon conductive velocity. This is also the graphene ball material battery rechargeable battery charge than the existing reason for five times faster. South Korea plans to five years will be "graphene ball" lithium electricity child lead battery.
