BIPOLAR SOLID-STATE BATTERY WITH ENHANCED INTERFACIAL CONTACT

A method for forming a bipolar solid-state battery may include preparing a plurality of freestanding gels each comprising a polymer, a solvent, and a lithium salt and, also, positioning a first freestanding gel between a first electrode and a second electrode and a second freestanding gel between the second electrode and a third electrode. Each of the first electrode, the second electrode, and the third electrode may include a plurality of electroactive particles. The method may also include infiltrating at least a portion of the first free-standing gel into a space between particles of the first electrode and the second electrode and at least a portion of the second free-standing gel into a space between the particles of second electrode and the third electrode.
