LITHIUM ION SECONDARY BATTERY, METHOD OF MANUFACTURING LITHIUM ION SECONDARY BATTERY AND METHOD FOR RECOVERING CAPACITY OF LITHIUM ION SECONDARY BATTERY

To provide a lithium ion secondary battery which cannot only compensate the irreversible capacity, which occurs in a first time charge but can respond to the degradation of an electrode, which occurs in the repeated use while enlarging the overall capacity of the lithium ion secondary battery.SOLUTION: A lithium ion secondary battery 100 includes: a positive electrode 10; a negative electrode 20 containing graphite and a silicon-based active material; a lithium ion supply pole 30 for supplying lithium ions to the positive electrode 10 or the negative electrode 20; and an electrolytic solution 40 for dipping the positive electrode 10, the negative electrode 20 and the lithium ion supply electrode 30 thereinto.SELECTED DRAWING: Figure 1 【課題】リチウムイオン二次電池全体の容量を大きくしつつも、初回の充電で発生する不可逆容量を補償するだけでなく、繰り返しの使用で生じる電極の劣化にも対応できるリチウムイオン二次電池を提供する。【解決手段】正極１０と、黒鉛とシリコン系の活物質とを含む負極２０と、正極１０又は負極２０にリチウムイオンを供給するリチウムイオン供給極３０と、正極１０、負極２０及びリチウムイオン供給極３０を浸漬する電解液４０と、を備えるリチウムイオン二次電池１００。【選択図】図１
