Coating material for electrodes

A method for coating an electrode, preferably an anode, preferably a lithium anode, said method comprising polymerizing a mixture comprising:

• a first monomer of formula I
• wherein:
• R1 and R2 are independently selected from hydrogen, optionally fluorinated C1-C6 alkyl, and O(C1-C6 alkyl);
• R3 is selected from hydrogen, optionally fluorinated C1-C6 alkyl, polydimethylsiloxane, and polyethylene oxide;
• and
• n is 0, 1, 2, or 3;
• optionally, a second monomer selected from the list consisting of cyclic or linear carbonates, cyclic or linear siloxanes, anhydrides, lactones, lactams, sultones, cyclic or linear ethers, spiro compounds, cyclic or linear sulfonamides, cyclic or linear amines, and oxathiolanes, preferably selected from:
• and a monomer of formula I other than the first monomer, wherein R9 is C1-C6 alkyl, polydimethylsiloxane, polyethylene oxide, CH2CF2H, CH2CH2CH2S(O)2NS(O)2CF3Li, CH2CH2CH2S(O)2NS(O)2CF2HLi, CH2CH2CH2S(O)2NS(O)2FLi;
• a glycidyl crosslinker with general formula
• wherein:
• Z and Z′ are independently selected from O, S or
• preferably Z═Z′;
• Y is one or more optionally substituted aromatic rings, one or more optionally substituted heteroaromatic rings or a siloxane polymeric chain;
• m and m′ are integers comprised between 0 and 6;
• and
• a ring-opening polymerization initiator.
