According to Korean media reports on November 27, Samsung Electronics announced today that the company has developed graphene battery technology, which can increase battery capacity and increase charging speed to five times the current standard.

According to the Samsung Advanced Institute of Technology (SAIT), the battery capacity based on graphene material is 45% higher than that of batteries currently on the market. Graphene, a form of carbon, is seen as a perfect material for battery applications because its electron mobility is about 140 times that of silicon.

Samsung says the battery equipped with "grapheneballs" can be fully charged in just 12 minutes. By comparison, existing batteries take an hour to fully charge. Because graphene batteries are stable at temperatures up to 60 degrees Celsius, the new batteries are also expected to be used in electric vehicles.

Samsung Advanced Technology Research Institute stated that they have published this research in the magazine "Nature Communications", titled "Graphene Balls for Rechargeable Li-ion Batteries Supporting Fast Charging and High Volumetric Energy Density" and published it in South Korea. and applied for a patent in the United States.
