摘要： An electrode material useful as a dry in place deposit comprising at least one metal chelating polymer; an active material capable of reversibly intercalating lithium ions; a plurality of electrical conductor particles; a binder polymer. The electrode material is formed into a slurry using a non-aqueous solvent. The metal chelating polymer may be a reaction product of a polyphenolic polymer; an aldehyde, a ketone, or mixtures thereof; and an amine. The electrode material slurry is deposited on a current collector and dried to form a positive electrode in a secondary lithium ion battery. The deposited electrode material has high flexibility, adhesion to the current collector, resistance to electrolyte damage, and low electrical resistance. The electrode material forms a superior positive electrode at a relatively low additional cost and with no increase in process complexity.

摘要： Disclosed is a lithium-sulfur battery capable of improving cycle lifetime performance, by using together with a positive electrode containing a sulfur-modified polyacrylonitrile (S-PAN)-based compound as an active material and a specific electrolyte showing a synergistic effect with it, so that the problems of dendrite formation and electrolyte decomposition and depletion, which occur when lithium metal is used as a negative electrode, are prevented. The lithium-sulfur battery comprises a positive electrode comprising at least one sulfur-modified polyacrylonitrile-based compound as an active material; lithium metal negative electrode; and an electrolyte containing a first solvent containing a heterocyclic compound containing one or more double bonds and at the same time containing any one of an oxygen atom and a sulfur atom, a second solvent containing diglyme and lithium salt.
