Abstract
Before laminating the electrolyte with the positive electrode, the electrolyte is heated at a temperature higher than its softening temperature or the melting temperature of its crystallites, and the heated electrolyte is allowed to return to room temperature before laminating the positive electrode to the electrolyte at room temperature. This enables to prevent the formation of wrinkles on the collector of the positive electrode.
