A polymer electrolyte is a polymer matrix capable of ion conduction.[1] Much like other types of electrolyte—liquid and solid-state—polymer electrolytes aid in movement of charge between the anode and cathode of a cell.[1][2][3] The use of polymers as an electrolyte was first demonstrated using dye-sensitized solar cells.[4] The field has expanded since and is now primarily focused on the development of polymer electrolytes with applications in batteries, fuel cells, and membranes.[4][5][6]
