Abstract
A method for forming a bipolar solid-state battery includes preparing a mixture of gel precursor solution and solid electrolyte. The gel precursor includes a polymer, a first solvent, and a liquid electrolyte. The liquid electrolyte includes a second solvent, a lithium salt, and electrolyte additive. The method includes loading the mixture onto at least one of a first electrode, a second electrode, and a third electrode. Each of the first, second, and third electrodes includes a plurality of solid-state electroactive particles. The method includes removing at least a portion of the first solvent from the mixture to form a gel and positioning one of the first, second, and third electrodes with respect to another of the first, second, and third electrodes. The method includes applying a polymer blocker to a border of the first, second, or third electrodes.
