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. The positive electrode used during assembly consists of a current collector having a comprises material which contains the positive active material and at least one sacrificial salt of a cations E⁺ is selected from among Li⁺, Na⁺, K⁺ and the onium cations, and a redox action selected from azide anions, ketocarboxylate anions, and hydrazide anions, optionally in the form of a polymers.
