CARBON NANOTUBE-COATED SILICON/METAL COMPOSITE PARTICLE, PREPARATION METHOD THEREOF, AND ANODE FOR SECONDARY BATTERY AND SECONDARY BATTERY USING THE SAME |
摘要 |
<P>PROBLEM TO BE SOLVED: To provide a method for preparing an electrode stock (namely, electrode active material) in which a big volume change generated during charge/discharge as the biggest problem in the commercialization of a silicon electrode stock is controlled, and the low electric conductivity properties of silicon are improved, and to provide an anode for a secondary battery and a secondary battery using the same. <P>SOLUTION: Carbon nanotube-coated silicon/metal composite particles in which the surfaces of the composite particles of silicon and metal are coated with carbon nanotubes are prepared, and, using an anode for a secondary battery containing a collector and an anode active material containing the carbon nanotube-coated silicon/metal composite particles, a secondary battery is prepared. <P>COPYRIGHT: (C)2010,JPO&INPIT |
