Title:
SIZE-CONTROLLED COSB2 NANOPARTICLES AND METHOD FOR PREPARING SAME
Document Type and Number:
WIPO Patent Application WO/2014/200152
Kind Code:
A1
Abstract:
The present invention relates to size-controlled CoSb2 nanoparticles and a method for preparing the same. More specifically, excellent productivity can be achieved while only CoSb2 is prepared in a single phase even without an independent separation procedure, and CoSb2 nanoparticles having high crystallinity and a nano-level size can be produced for a short time. Further, CoSb2 nanoparticles which have a size controllable according to the use thereof and a uniform particle size but have neither problems such as different kinds of crystalline structures and irregular sizes due to nucleation and growth of individual metal elements, nor impurities. Further, the CoSb2 nanoparticles according to the present invention have better durability and higher cell capacitance than a positive electrode material for a lithium secondary cell of the prior art, and thus can be used as an electrode material for a lithium secondary cell or the like.
