METHOD FOR PRODUCING A LITHIUM OR SODIUM BATTERY

摘要

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 first 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 mixtures 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+/Aº couple. The active material of the positive electrode is a material which has a redox couple, the potential of which is higher than that of the couple of the negative electrode. The positive electrode used during assembly consists of a current collector having a composite material which contains the positive active material and at least one sacrificial salt of a cation E+ selected from among Li+, Na+, K+ and the onium cations, and a redox anion selected from among azide anions, ketocarboxylate anions, and hydrazide anions optionally in the form of a polymer.
