Title:
プレリチオ化負極（Ｐｒｅｌｉｔｈｉａｔｅｄ ｎｅｇａｔｉｖｅ ｅｌｅｃｔｒｏｄｅ）、その作製方法、プレリチオ化負極を含むリチウムイオン電池、及びスーパーコンデンサー
Document Type and Number:
Japanese Patent JP7252988
Kind Code:
B2
Abstract:
The present invention provides a prelithiated negative electrode, a preparation method thereof, and a lithium ion battery and a supercapacitor comprising the same. The prelithiated negative electrode comprises: an electrode film which is a solvent-free film-like negative electrode material composed of a negative electrode active material, a lithium-skeleton carbon composite material, a binder and optionally a conductive additive; and a metal current collector, wherein the electrode film is bonded on the metal current collector through a conductive adhesive. The present invention provides an effective method of prelithiating a negative electrode, and can effectively improve the first cycle efficiency of a lithium battery comprising a silicon-carbon negative electrode, contributing to increasing the specific capacity and cycle life of the battery. The present invention can also increase the energy density of a supercapacitor.
