    摘要: This disclosure relates to rechargeable battery packs and or rechargeable battery modules consisting of electrochemical cells in general and more specifically to lithium metal anode secondary electrochemical cells and the supporting mechanical structure of such packs or modules which apply and maintain a high and uniform normal compression pressure to the face of the interconnected cells of said battery packs, modules or individual cells, in order to suppress dendrite formation during charge and maintain a low cell impedance during charge and discharge. This is achieved with the use of a compression assembly having a compressible sheet with desired properties.

    摘要: Disclosed is an electrochemical cell having a polymer solid electrolyte comprising a polymer localized on surface of an electrode. In one aspect, the localized polymer physically decreases or prevents exposure of freshly cracked electrode to a flammable solvent under extreme conditions, thus leading to an improved safety profile of the cell. In one aspect, the disclosure provides a polymer solid electrolyte comprising a polymer localized on surface of an electrode. Methods for preparing the same are also disclosed.

    摘要: A cell assembly has a plurality of first electrodes, a plurality of second electrodes and a plurality of solid electrolyte layers. The solid electrolyte layers have a protrusion in at least one of the solid electrolyte layers. The protrusion is aligned with a first electrode tab of one of the first electrodes. The folding of the first electrode tabs causes the protrusions to be positioned to separate the first electrode tabs from the second electrodes, thus preventing short circuit between the first electrode tabs and second electrodes. In one aspect, the disclosure provides an all solid-state battery comprising one or more anodes, one or more cathodes and one or more solid electrolyte layers with a protrusion. Also disclosed is a method for preparing same.
