New design uses silicon nanoparticles to improve capacity and recharge more quickly Researchers at USC have developed a new lithium-ion battery design that uses porous silicon nanoparticles in place of the traditional graphite anodes to provide superior performance. The new batteries–which could be used in anything from cell phones to hybrid cars–hold three times as much energy as comparable graphite-based designs and recharge within 10 minutes. The design, currently under a...

A flexible, printable material 4-or-fewer-atoms-thick may be a high road to economical and convenient electrical power from the sun A University of Southern California team has produced flexible transparent carbon atom films that the researchers say have great potential for a new breed of solar cells. "Organic photovoltaic (OPV) cells have been proposed as a means to achieve low cost energy due to their ease of manufacture, light weight, and compatibility with flexible substrates," wrote...
