Abstract:
1. A battery comprising: a cathode; an anode; and an electrolyte, wherein, (a) the electrolyte contains a high molecular weight compound, a solvent containing a high viscosity solvent whose boiling point is more than 150° C. and a low viscosity solvent whose boiling point is 150° C. or less, and an electrolyte salt, (b) the electrolyte is formed by forming a coating layer containing the high molecular weight compound, the high viscosity solvent, and the electrolyte salt on the cathode and the anode, and then injecting an injection solution containing the low viscosity solvent in the coating layer, and (c) the electrolyte is formed by using the injection solution which contains an electrolyte salt in relation to the lower viscosity solvent having a higher concentration than a content of an electrolyte salt in relation to the high viscosity solvent in the coating layer.
