摘要： Provided are methods of forming an electrode suitable for use in an electrochemical cell, and novel electrodes which can be formed therefrom. The methods involve the steps of: (a) forming an electrode slurry from components comprising a solvent, a polymeric binder material and a solid electrode material, wherein the polymeric binder material is formed by modifying a polyolefin with at least one unsaturated polycarboxylic acid or an anhydride of the acid, chlorinating the modified polyolefin and partially crosslinking carboxyl groups or acid anhydride groups on the chlorinated, modified polyolefin with an epoxy group of a compound which has at least two epoxy groups per molecule; (b) coating the electrode slurry on a substrate; and (c) evaporating the solvent. Also provided are electrochemical cells which include the inventive electrodes. The invention has particular applicability to the manufacture of nonaqueous electrochemical power supplies.
