Aqueous electrode binders for lithium ion batteries

An aqueous binder composition (C1) for use in the preparation of electrodes for an electrochemical devices, wherein the aqueous binder composition (C1) comprises:

• at least one polymer (A), wherein polymer (A) is at least one vinylidene fluoride (VDF) copolymer comprising recurring units derived from vinylidene fluoride (VDF) monomer and recurring units derived from at least one hydrophilic (meth)acrylic monomer (MA) of formula (I):
• wherein each of R1, R2, R3, equal or different from each other, is independently an hydrogen atom or a C1-C3 hydrocarbon group, and ROH is a hydrogen or a C1-C5 hydrocarbon moiety comprising at least one hydroxyl group;
• at least one styrene-butadiene rubber (SBR);
• and
• at least one cellulose-based dispersing agent.
