Description
본 발명은 주석 및 니켈의 합금 전극을 이용하여 리튬 이온 이차 전지의 음극소재 및 이의 제조 방법을 제공하는데 있다.
The present invention provides a negative electrode material of a lithium ion secondary battery and a method of manufacturing the same using an alloy electrode of tin and nickel.
전지는 양극과 음극에 전기 화학 반응이 가능한 물질을 사용함으로써 전력을 발생시키는 것이다. 이러한 전지 중 대표적인 예로는 양극 및 음극에서 리튬 이온이 삽입 및 탈리될 때의 화학전위(chemical potential)의 변화에 의하여 전기 에너지를 생성하는 리튬 이차 전지가 있다.Cells generate electricity by using materials that can electrochemically react to the positive and negative electrodes. A typical example of such a battery is a lithium secondary battery that generates electrical energy by a change in chemical potential when lithium ions are inserted and desorbed at a positive electrode and a negative electrode.
상기 리튬 이차 전지는 리튬 이온의 가역적인 삽입 및 탈리가 가능한 물질을 양극 활물질과 음극 활물질로 사용하고, 상기 양극과 음극 사이에 유기 전해질 또는 폴리머 전해질을 충전시켜 제조한다.The lithium secondary battery is manufactured by using a material capable of reversible insertion and detachment of lithium ions as a positive electrode active material and a negative electrode active material, and filling an organic electrolyte or a polymer electrolyte between the positive electrode and the negative electrode.
리튬이온 이차전지의 음극소재로 주로 이용되고 있는 graphite의 경우 이론용량 한계에 이르렀기 때문에, 그 이상으로 용량을 증가시키기 위한 새로운 음극재료의 개발이 진행되고 있다. Graphite의 대체 물질로서, Sn의 경우 graphite 전극 대비 무게 당, 혹은 부피 당 용량이 2~3배 높아 주목받고 있으나, 충방전 시 부피변화가 300% 이상 발생하여 전극에 균열이 발생하고 이로써 전극의 수명이 짧다는 문제가 있다.
Since graphite, which is mainly used as a negative electrode material of a lithium ion secondary battery, has reached a theoretical capacity limit, development of a new negative electrode material for increasing capacity beyond that is being progressed. As an alternative to graphite, Sn has attracted attention because its capacity per weight or volume is 2 to 3 times higher than that of graphite electrodes. There is a problem with this short.
이에 본 발명자들은 상기 짧은 전극 수명을 향상시키기 위한 대안으로 Sn전극에 Li과 반응하지 않는, 즉 Li에 대해 inactive한 원소를 합금화 함으로써, 충방전 시 발생하는 Li과 Sn의 부피변화를 완충하도록 하여 전극의 수명을 향상시킬 수 있는 합금 전극을 개발하였다. Accordingly, the present inventors alloy the element which does not react with Li to the Sn electrode, that is, inactive to Li as an alternative to improve the short electrode life, thereby buffering the volume change of Li and Sn generated during charging and discharging. An alloy electrode has been developed that can improve the life of the alloy.
본 발명에서는 inactive한 원소로써 Ni을 사용한 Sn-Ni 합금전극을 전기도금방법을 이용하여 개발하고자 한다.
In the present invention, to develop a Sn-Ni alloy electrode using Ni as an inactive element using an electroplating method.
