  • NEGATIVE ELECTRODE MATERIAL FOR NONAQUEOUS ELECTROLYTE SECONDARY BATTERY AND METHOD FOR MANUFACTURING THE SAME
    Publication number: 20130334468
    Abstract: The present invention provides a method for manufacturing a negative electrode material for a nonaqueous electrolyte secondary battery, which includes the steps of: preparing silicon nanoparticles; manufacturing the silicon-carbon composite material that contains the silicon nanoparticles and a carbonaceous material; and heat-compressing the silicon-carbon composite material. As a result, there is provided a negative electrode material for a nonaqueous electrolyte secondary battery, which has a high capacity and excellent initial charge/discharge efficiency and cycle characteristics and a method for manufacturing the same, and a nonaqueous electrolyte secondary battery that uses the negative electrode material for a nonaqueous electrolyte secondary battery.
