Abstract
The present disclosure relates to solid-state batteries and methods for forming solid-state batteries. The method includes contacting a polymeric precursor and an assembled battery including two or more electrodes defining a space therebetween, where the polymeric precursor fills the space defined between the two or more electrodes and any voids between the solid-state electroactive particles of each electrode; and reacting the polymeric precursor to form a polymeric gel electrolyte that forms a solid-state electrolyte layer in the space between the two or more electrodes and fills the voids between the solid-state electroactive particles of the electrodes. In other instances the method includes disposing the polymeric precursor on exposed surfaces of an electrode and reacting the polymeric precursor to form the solid-state electrolyte. In still other instances, the method includes disposing the polymeric precursor on a releasable film and reacting the polymeric precursor to form the free-standing electrolyte layer.
