2 전해질 또는 CaCl
2 이 함유된 혼합염 용융체 전해질 속에 넣어 전해조를 형성한 후, 캐소드 및 애노드 사이에 전해 직류 전압을 인가하여, 전해전압, 전해전류의 밀도 및 전해 전기량을 제어함으로써, 다공성 블록 내의 실리카를 나노규소로 전해 환원시켜, 캐소드에서 리튬 이온 전지용 나노규소/탄소 복합 재료를 수득하는 것입니다.
The present invention is a lithium ion battery nano-silicon carbide mixed material, and relates to its manufacturing method, the silica and to the porous electrodes composed of carbon as a raw material nano-carbon surface of a silicon via in situ electrochemical reduction on silica using a molten salt electrolysis forming a silicon / carbon composite material. The material has between silicon and carbon is improved the electrochemical stability of the cycle as metallurgical-grade compositions are connected through the nano-silicon carbide, nano-silicon and carbon composite materials. Method for producing a nano-silicon / carbon composite material provided in the present invention, the mixture of the porous block and electrically conductive cathode current collector consisting of carbon and silica powder as a cathode, and a graphite or an inert anode to the anode, the cathode and anode one to form the put the electrolytic cell in the mixed salt molten electrolyte containing CaCl
2 electrolyte or CaCl
2 and then, by applying a DC voltage to be delivered between the cathode and the anode and the electrolytic voltage, electrolytic controlling the density and the electrolysis electric quantity of current, the porous block by electrolytic reduction of silica in a nano-silicon, it is to obtain a lithium-ion battery nano-silicon / carbon composite material in the cathode.
