Disclosed is an electrode material designed for in situ drying of a deposit comprising at least one metal chelate polymer; an active material capable of reversibly inserting lithium ions; a plurality of conductive particles; a binder polymer. The electrode material forms a slurry using a non-aqueous solvent. The metal chelating polymer can be the reaction product of a polyphenolic polymer; an aldehyde, a ketone, or a mixture thereof; and an amine. The electrode material slurry is deposited on the current collector and dried to form a positive electrode in the lithium ion secondary battery. The deposited electrode material has high flexibility, adhesion to current collectors, resistance to electrolyte damage, and low electrical resistance. The electrode material forms a good positive electrode at a relatively low additional cost and without increasing process complexity. |
