Abstract

A rechargeable electrochemical metal ion cell comprising: - a negative electrode (anode) (1 ); - a positive electrode (cathode) (2); - an electrolyte system (3) interposed between said negative electrode and said positive electrode, wherein: - said negative electrode (1) comprises at least one metal capable of releasing and accepting metal ions; - said positive electrode (2) comprises at least one compound capable of releasing and accepting metal ions different from those of the negative electrode (1); - said electrolyte system (3) comprises: - a glycol-based electrolyte solution containing a salt of a metal included in the negative electrode (1 ) and a salt of a metal included in the positive electrode (2); - a matrix of solid and/or polymer and/or gel type adapted to retain said electrolyte solution, where two reversible reactions take place simultaneously in said cell: a reversible deposition and dissolution process of ions of a metal included in the negative electrode (1 ) takes place in said negative electrode and a reversible ion exchange process of a metal included in the positive electrode (2) takes place in said positive electrode and said metals are different from one another.
