Abstract
Provided are an electrolyte having superior adhesion strength to an electrode and superior permeability into the electrode, and a battery using the electrolyte. An electrolyte comprises, for example, a high molecular weight compound and an electrolyte solution prepared by dissolving an electrolyte salt in a solvent, and the electrolyte is formed through applying a coating solution prepared by dissolving the high molecular weight compound in a mixed solvent to at least either a cathode or an anode. The high molecular weight compound includes a first high molecular weight compound with a weight-average molecular weight of 550,000 or more and a second high molecular weight compound with a weight-average molecular weight of 1,000 or more but not exceeding 300,000. Thereby, the adhesion strength of the electrolyte to the electrode, the permeability of the electrolyte into the electrode and the mechanical strength of the electrolyte can be improved, and the capability of holding a solvent can be improved.
