Samsung has synthesised “graphene balls” that can boost its batteries

Samsung Electronics has developed core battery technology using graphene to make lithium-ion batteries last longer and charge more quickly, a potential industry milestone if mass produced. The South Korean conglomerate said yesterday that its research arm — Samsung Advanced Institute of Technology (SAIT) — has successfully synthesised “graphene balls” that can boost its battery capacity by 45 per cent and increase charging speed by five times the existing standards. Graphene has been touted in the global electronics industry as a “miracle material” given its strength, electrical conductivity and elasticity, and has been seen as an alternative to lithium-ion batteries since its discovery in 2004. It is a form of carbon that can be used to develop smaller, slimmer batteries but with higher capacity. Samsung said the graphene-based battery would take just 12 minutes to be fully charged; current lithium-ion batteries take about an hour. The new battery could also be used for electric vehicles, as it can maintain stability at up to 60 degrees Celsius… Graphene… can be used in flexible displays, wearables and other next-generation electronic devices. But while lithium-ion battery technology — first commercialised in 1991 — is seen to be reaching its limitations, experts caution it will be years before graphene-based battery technology is ready for commercialisation.
