  • Publication number: 20260031390
    Abstract: 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.

  • Publication number: 20250266490
    Abstract: Disclosed is a densified cell assembly and methods for preparing the same. In one embodiment, an isostatic press is applied to a bag which contains a plate and two elastic substrates enveloping a cell pouch, wherein one or more tabs are extended from the cell pouch, wherein the cell pouch accommodates a cell stack comprising one or more electrode layers and one or more electrolyte layers. In one embodiment, the tabs are not damaged or disconnected from the cell pouch due to compression.
