Abstract: 본 발명은 음극활물질, 양극활물질 및 전해질을 포함하는 리튬이차전지에 있어서, 상기 음극활물질이 금속 주석 및 리튬 산화물을 포함하는 것을 특징으로 하는 리튬이차전지에 관한 것이다. 상기 음극활물질은 주석층/리튬산화물층/주석층으로 순차 적층된 조성변조상, 또는 주석과 리튬산화물이 혼합된 복합상으로 구성되어 있다.
주석/리튬 산화물을 리튬이차전지용 음극활물질로 사용함에 의해 리튬의 삽입ㆍ방출 반응시 나타나는 체적변화를 수용하여 초기 쿨롱효율을 높이고, 수명특성을 향상시킨, 안정한 음극을 제조할 수 있다. 그리고 기존의 주석산화물은 열처리 과정을 동반하지만, 본 발명에 의한 조성변조상/복합상 구조의 주석산화물은 별도의 열처리 공정이 필요 없기 때문에 비용의 절감뿐 만 아니라, 고분자 필름 위에 구현하는 것도 가능하므로 매우 유용하다.-

Abstract: PURPOSE: Provided is a lithium secondary battery consisting of anode active materials, cathode active materials and electrolyte in which cathode active materials are metal tin and lithium oxide. The active material comprises either layered composition modulating form of tin layer/lithium oxide layer/tin layer or tin and lithium oxide complex form. The battery is characterized in that initial coulomb efficiency is high because the volume change in insertion and discharge reaction of lithium is tolerated thereby producing stable cathode. While conventional tin oxide need heat treatment, this composition of modulation/complex tin oxide do not need the treatment, thereby making the battery cheap. It is also very useful because it can be implemented on polymer film. CONSTITUTION: The battery is composed of tin/lithium cathode active material with the thickness of 1000angstrom-100micrometer, where tin/lithium thickness is in a ratio of 1:00l-1:100, thickness of basic tin being 1angstrom-1micrometer and lithium oxide being 1angstrom-1micrometer. Tin is in a crystal form and lithium oxide is amorphous. The tin/lithium complex cathode active material is prepared by the method of physical vapor deposit (VD) such as heat VD, electron beam VD, sputtering, ion beam VD, laser ablation; chemical vapor deposit (CVD) such as low and/or atmospheric pressure CVD, plasma added CVD and organic metal CVD and sol-gel method, spin coating method or static spraying method.
