Claims16
An electrode-forming composition, composition (C), comprising:
- a) at least one electrode active material (AM);
- b) at least one binder (B), wherein binder (B) comprises at least one vinylidene fluoride (VDF) polymer, polymer (A), wherein polymer (A) is obtained by a process comprising a step of irradiating a polymer (F) with an ionizing radiation in the presence of oxygen at a dosage lower than 70 kGy, wherein polymer (F) comprises:
- (i) recurring units derived from vinylidene fluoride (VDF), and
- (ii) optionally from 0.01% by moles to 15.0% by moles of recurring units derived from a fluorinated comonomer (CF), different from VDF, the aforementioned percentages by mole being referred to the total moles of recurring units of polymer (F);
- and
- c) at least one solvent (S).

An electrode (E) comprising:
- a metal substrate, and
- directly adhered onto at least one surface of said metal substrate, at least one layer comprising a composition comprising:
- (a) at least one polymer (A), wherein polymer (A) is obtained by a process comprising a step of irradiating a polymer (F) with an ionizing radiation in the presence of oxygen at a dosage lower than 70 kGy, wherein polymer (F) comprises:
- (i) recurring units derived from vinylidene fluoride (VDF), and
- (ii) optionally from 0.01% by moles to 15.0% by moles of recurring units derived from a fluorinated comonomer (CF), different from VDF, the aforementioned percentages by mole being referred to the total moles of recurring units of polymer (F);
