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.
