Researchers from the University of Eastern Finland introduced new technology to Li-ion batteries by replacing graphite used in anodes by silicon. Silicon could quadruple anode capacity if used to replace graphite in lithium-ion batteries, according to researchers from the University of Eastern Finland. The new material is a mixture of graphene and silicon nitride that can be made into electrodes for lithium batteries by adding just one more layer onto existing graphene, said researcher Juha Tuominen. The researchers will also test silicon alongside carbon nanotubes to improve electrical conductivity and durability. At present, silicon is too expensive for commercial, large-scale production, leading the team to examine if it could be produced from agricultural waste products.
