Samsung Researchers Make Battery Breakthrough
Jun 29, 2015, 7:12 AM by Eric M. Zeman
A research team working at Samsung has discovered a new way to make lithium-ion batteries that could double the available battery life in devices such as smartphones. The method involves covering silicon nanoparticles with graphene, which prevents the formation of silicon carbide. "When paired with a commercial lithium cobalt oxide cathode, the silicon carbide-free graphene coating allows the full cell to reach volumetric energy densities [that are up to] 1.8 times higher than those of current commercial lithium-ion batteries," explain the researchers. They believe this can serve as a prototype for eventually bringing the technology to market. The end result would be batteries that last almost twice as long as they do now. Samsung said this discovery is still in the early stages of development and did not provide a suggested timeline for commercial release.
