ANODE FOR LITHIUM-ION BATTERY

摘要

An anode for a lithium-ion battery is presented as well as a process for producing an anode for a lithium-ion battery. The anode is formed from a generally continuous sheet of particles of exfoliated graphite having a thickness of no more than about 350 microns, itself or in a laminate with a metallic substrate. The process involves laminating particles of exfoliated graphite to a metallic substrate, such that the particles of exfoliated graphite form a generally continuous sheet of graphite having a thickness of no more than about 350 microns. The inventive anode reduces or eliminates capacity fading due to contact loss and has superior permeability to lithium.
