The South Korean tech giant said on Monday that its research and development unit Samsung Advanced Institute of Technology (SAIT) developed new type of rechargeable battery applied with graphene balls. Graphene, dubbed to be the strongest and lightest material, is an allotrope of carbon atoms and highly ideal candidate for rechargeable batteries because of its remarkable electron mobility.
The Li-ion battery prototype based on graphene ball has 45 percent larger capacity and can fully recharge within 12 minutes. It takes usually an hour for a Li-ion battery to fully charge.
They can maintain stability under heat of up to 60 degrees Celsius, which make them safe to power electric vehicles, according to the company.
Its new R&D achievement was published in the international journal Nature Communications under the title “Graphene balls for lithium rechargeable batteries with fast charging and high volumetric energy densities,” earlier this month.
SAIT said it has applied for patents related to the graphene ball technology in Korea and the United States.
At 12:13 p.m. Monday, shares of Samsung Electronics were down 3.93 percent at 2,664,000 won ($2,447.18).
