In-situ gelation method to make a bipolar solid-state battery

A method for forming a bipolar solid-state battery, the method comprising:

• applying a polymer blocker to one or more of borders of a first electrode, a second electrode, and a third electrode;
• positioning one of the first electrode, the second electrode, and the third electrode with respect to another of the first electrode, the second electrode, and the third electrode;
• and
• solidifying the polymer blocker.

A method for forming a bipolar solid-state battery, the method comprising:

• preparing a mixture of gel precursor solution and solid electrolyte, wherein the gel precursor comprises a polymer, a first solvent, and a liquid electrolyte, wherein the liquid electrolyte comprises a second solvent and a lithium salt;
• loading the mixture of the gel precursor solution and the solid electrolyte onto at least one of a negative electrode including a first plurality of negative solid-state electroactive particles, a first side of a bipolar electrode having a first plurality of positive solid-state electroactive particles, a second side of the bipolar electrode having a second plurality of negative solid-state electroactive particles, or a positive electrode having a second plurality of positive solid-state electroactive particles;
• evaporating at least a portion of the first solvent from the mixture of gel precursor and solid electrolyte to form a gel;
• applying a polymer blocker to two of the negative electrode, the first side of the bipolar electrode, the second side of the bipolar electrode, and the positive electrode;
• positioning the negative electrode adjacent to the first side of the bipolar electrode and the positive electrode adjacent to the second side of the bipolar electrode;
• and
• solidifying the polymer blocker.
