Abstract
In a rechargeable lithium battery including inter alia a lithium anode, a lithium ion reducible cathode bonded with a polymer, as well as a polymer electrolyte, potassium ions are introduced either in the cathode or in the electrolyte, or in both of them at the same time, so that potassium is distributed in the cathode and the electrolyte when the generator has reached equilibrium. This has the effect of stabilizing the performances of the battery during cycling in terms of energy and power.
