- Existing lithium batteries, which were developed and commercialized by Sony in the 90’s, has been developed in a way of extending the capacity rather than increasing the life and density owing to limitations of material itself.
- The R&D center of Samsung Electronics has succeeded in developing a high-density and highly-durable cathode material by coating the strong and conductive graphene on the surface of the silicon to create a kind of protective layer around the silicon.
- Samsung, which has been making efforts to improve battery capacity to differentiate itself from other global smartphone rivals, expects that the technology may need two or three years for commercialization.
