Abstract
Official abstract text for this publication.
Electrode protection in electrochemical cells, and more specifically, electrode protection in both aqueous and non-aqueous electrochemical cells, including rechargeable lithium batteries, are presented. In one embodiment, an electrochemical cell includes an anode comprising lithium and a multi-layered structure positioned between the anode and an electrolyte of the cell. A multi-layered structure can include at least a first single-ion conductive material layer, and at least a first polymeric layer positioned between the anode and the single-ion conductive material. The invention also can provide an electrode stabilization layer positioned within the electrode to control depletion and re-plating of electrode material upon charge and discharge of a battery. Advantageously, electrochemical cells comprising combinations of structures described herein are not only compatible with environments that are typically unsuitable for lithium, but the cells may be also capable of displaying long cycle life, high lithium cycling efficiency, and high energy density.
First claim
Opening claim text (preview).
What is claimed is: 1. An anode for use in an electrochemical cell, comprising: a first electroactive layer comprising an active electrode species; a second electroactive layer comprising the active electrode species, wherein the anode is adapted and arranged such that when the anode is present in an electrochemical cell, at least some of the active electrode species in the second electroactive layer is depleted and replated upon discharge and charge, respectively, of the electr…
