Samsung Researchers Make Battery Breakthrough
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.

MIT Spinout Claims to Double Battery Life
Aug 19, 2016
A company called SolidEnergy Systems, a spinout from MIT, says it has new battery technology that will double the life of lithium-based power cells. The breakthrough involves a battery that replaces the traditional graphite anode with a thin, lithium-metal foil.
Gold Wires and Electrolyte Gel Improve Battery Longevity
Apr 22, 2016
Researchers at the University of California at Irvine say they've found a way to increase the number of charge cycles a battery has from a few thousand to more than 200,000. Their discovery could lead to batteries that can be recharged repeatedly for years without losing capacity, which his something that happens with today's lithium-ion batteries.
