Abstract
The invention concerns an all-solid-state electrochemical generator (1) comprising a negative electrode (4) capable of supplying a lithium cation, an all-solid-state polymer electrolyte (3) formed with a macromolecular material wherein ionised lithium salt is dissolved and a second positive electrode capable of incorporating a non-ionised species corresponding to said lithium cation. The invention is characterised in that the all-solid-state polymer electrolyte comprises one or several fluorinated polymer(s) and the mass ratio macromolecular material/fluorinated polymer(s) ranges between 6 and 700.
