Abstract: The present invention relates to a terpene resin-based composite binder for the preparation of electrodes of lithium-ion battery cathode or supercapacitor. The terpene resin-based composite binder is a terpene resin-based aqueous binder or a terpene resin-based oil binder; the terpene resin-based aqueous binder comprises a water-soluble terpene resin emulsion and a water-soluble polymer auxiliary agent, the water-soluble polymer auxiliary agent is one or more selected from the group of carboxymethyl cellulose, polyacrylic acid or metal salts, a mass ratio of a terpene resin in the water-soluble terpene resin emulsion to the water-soluble polymer auxiliary agent is 50:1 to 1:50; the terpene resin-based oil binder comprises an oil-soluble terpene resin and an oil-soluble polymer auxiliary agent, the oil-soluble polymer auxiliary agent is a polyvinylidene fluoride, a mass ratio of the oil-soluble terpene resin to the polyvinylidene fluoride ranges from 1:4 to 1:50.

Abstract: A method of preparing an anode of lithium ion batteries or an electrode plate of a supercapacitor. The method includes admixing a terpene resin-based aqueous binder. The terpene resin-based aqueous binder includes a terpene resin emulsion including between 20 and 80 wt. % of a terpene resin, and the terpene resin emulsion has a viscosity of between 2000 and 10000 mPa·s.

Abstract: Disclosed is an aqueous composite binder of natural polymer derivative-conducting polymer. The composite binder comprises a natural polymer derivative and a water-soluble conducting polymer at a mass ratio of 1:3.75 to 1:0.038. The composite binder can be used for a conducting electrode material and a binder material of an electrochemical energy storage device, in particular for manufacturing a lithium ion battery, a capacitor or other energy storage system. Also disclosed are a plate electrode for an enemy storage device containing the composite binder and an energy storage device containing the plate electrode.
