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.
9 Ways to Maximize Your Smartphone Battery Life
Battery life continues to be one of the biggest limitations facing modern mobile devices. Batteries can only last so long when you're sending messages, snapping pix, and streaming media for hours on end.

MIT Spinout Claims to Double Battery Life
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.
AT&T's Latest GoPhone Runs On AA Batteries
AT&T today announced the SpareOne Emergency Phone, a simple handset meant purely to serve as a backup phone for critical situations. The SpareOne runs on AA batteries, rather than a rechargeable lithium-polymer power cell.
Researchers Devise Fire-Resistant Battery
Adding a flame-retardant to select elements of lithium ion batteries many prevent fires, according to researchers at Stanford University. The researchers figured out how to create a nonwoven electrospun separator out of triphenyl phosphate and coated it with a heat-activated polymer.
