    摘要： Primer arrangements that facilitate electrical conduction and adhesive connection between an electroactive material and a current collector are presented. In some embodiments, primer arrangements described herein include first and second primer layers. The first primer layer may be designed to provide good adhesion to a conductive support. In one particular embodiment, the first primer layer comprises a substantially uncrosslinked polymer having hydroxyl functional groups, e.g., polyvinyl alcohol. The materials used to form the second primer layer may be chosen such that the second primer layer adheres well to both the first primer layer and an electroactive layer. In certain embodiments including combinations of first and second primer layers, one or both of the first and second primer layers comprises less than 30% by weight of a crosslinked polymeric material. A primer including only a single layer of polymeric material is also provided.

    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. Rechargeable batteries comprising lithium anodes for use in water and/or air environments, as well as non-aqueous and non-air environments are also described. 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 to the application of a force to enhance the performance of an electrochemical cell. The force may comprise, in some instances, an anisotropic force with a component normal to an active surface of the anode of the electrochemical cell. In the embodiments described herein, the electrochemical cells (e.g., rechargeable batteries) may undergo a charge/discharge cycle involving deposition of metal (e.g., lithium metal) on a surface of the anode upon charging and reaction of the metal on the anode surface, wherein the metal diffuses from the anode surface, upon discharging. The uniformity with which the metal is deposited on the anode may affect cell performance. For example, when lithium metal is redeposited on an anode, it may, in some cases, deposit unevenly forming a rough surface. The roughened surface may increase the amount of lithium metal available for undesired chemical reactions which may result in decreased cycling lifetime and/or poor cell performance. The application of force to the electrochemical cell has been found, in accordance with the invention, to reduce such behaviour and to improve the cycling lifetime and/or performance of the cell.
