    摘要: 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 (e.g., a lithiated metal 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, i.e., between one portion and another portion of an 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.

    摘要: The present invention relates generally to electrochemical cells, and more specifically, to additives for electrochemical cells which may enhance the performance of the cell. In some cases, the additive may advantageously reduce or prevent formation of impurities and/or depletion of active components of the cell during operation, to increase the efficiency and/or lifetime of the cell. The incorporation of certain additives within the electrolyte of the cell may improve the cycling lifetime and/or performance of the cell.
