South Korea Has Successfully Developed A New Battery Material Called Graphene Ball

- Jun 09, 2018-

Recently, according to south Korean media reported that 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 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, which are 100 times more conductive than copper and more than 140 times more conductive than silicon.That's why graphene ball batteries charge five times faster than existing rechargeable batteries.South Korea plans to commercialize its graphene ball lithium-ion battery within five years.
