According to South Korea "central daily" report, samsung electronics research institute of comprehensive technology of group successfully developed a new battery material graphene. 45% higher than current lithium ion battery charging capacity, charging speed increased by more than 5 times.The results are 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 has long been considered a representative material in the new generation of materials.
The graphene from graphite is a thin carbon atomic membrane, characterized by high stability of physical and chemical properties.The material is 100 times more conductive than copper.
It is more than 140 times more conductive than silicon.This is why graphene ball cells are five times faster than existing rechargeable batteries.South Korea plans to commercialize graphene spheres in five years.
