Lithium rechargeable work in the systems with polymer electrolytes based on C-PVC and PVDE

Electrochemical behavior of Li in the systems with PE based on polymers of chlorinated polyvinylchloride and polyvinylidene fluoride were investigated by the method of cyclic voltammetry and galvanostatic cycling. Potentiodynamic investigations have shown that on lithium electrode even in the systems with polymer electrolyte the high current densities up to 5 mA/cm² are realized. Influence of polymer electrolyte composition on the properties of the interface Li/electrolyte and rechargeable work of lithium electrode has been shown. The developed PE have been tested in the pilot prototypes of power sources of the system Li-LiMn₂O₄ и Li-MnO₂.
