Lithium-polymer batteries
Rechargeable batteries — Lithium batteries

In a lithium-polymer battery, the negative electrode is a lithium thin film, the positive electrode, a reversible insertion compound, selected from those for "low-voltage" cathode (V ₆O₁₃, LiV₃O₈, TiS₂) or "high voltage" (LiMn ₂O₄), the electrolyte, finally, a polymer, such as polyethylene oxide, charged with lithium ions (POE – LiX). If, therefore, the presence of a lithium anode leads to envisage high specific performances, two difficulties are to be expected, the risk of dendrites associated with the lithium electrode and the need to operate at a temperature of the order of 80-100 ˚C, for the ionic conductivity of the electrolyte to be sufficient. Generally, and in order to improve contact with the electrolyte, the positive electrode is not made of the insertion compound alone and is elaborated in the following way. The...
