Abstract
Official abstract text for this publication.
A surface-controlled, lithium ion-exchanging battery device comprising: (a) A positive electrode (cathode) comprising a first functional material having a first lithium-capturing or lithium-storing surface; (b) A negative electrode (anode) comprising a second functional material having a second lithium-capturing or lithium-storing surface; (c) A porous separator disposed between the two electrodes, and (d) A lithium-containing electrolyte (preferably liquid or gel electrolyte) in physical contact with the two electrodes; wherein at least one of the two electrodes contains therein a lithium source (e.g., lithium foil, lithium powder, stabilized lithium particles, etc) prior to the first charge or the first discharge cycle of the battery device. This new generation of energy storage device exhibits the best properties of both the lithium ion battery and the supercapacitor.
First claim
Opening claim text (preview).
We claim: 1. A surface-controlled, lithium ion-exchanging battery device comprising: (a) a positive electrode consisting of a first functional material having a first lithium-capturing or lithium-storing surface to store lithium ions or atoms thereon, wherein said first functional material is selected from the group consisting of: (A) a disordered carbon material selected from a soft carbon, hard carbon, polymeric carbon or carbonized resin, meso-phase carbon, coke, carbonized pit…
