Abstract: The invention relates to a method for producing a battery using A+ (Li+ or Na+) as an electrochemical carrier, as well as to the resulting batteries. The method involves assembling together a negative electrode, a positive electrode, and an electrolyte, and then exposing the assembly to a firm charge at the operating temperature of the battery. The electrolyte is a ceramic or a solution of an A+ salt in a polar liquid, a polymer, or the mixture thereof. The active material of the negative electrode is a material which has a redox couple, the potential of which is 0 V to 1.6 V relative to the A+/A+ couple. The active material of the positive electrode is a material which has a redox couple, the potential of which is higher then that of the couple of the negative electrode.
