LIVERMORE, CA—Researchers at Sandia National Laboratories have developed composite anode materials composed of silicon and graphite that may double the energy storage capacities currently possessed by graphite anodes. This could potentially lead to rechargeable lithiumion batteries with more power, longer life and smaller sizes.
"Manufacturers of electric automobiles, laptop computers, cell phones, power tools and other hybrid microsystems will likely all benefit from this kind of technology," says Scott Vaupen of Sandia California's Business Development Department.
