ELECTRODE COMPOSITION, ELECTRODE AND BATTERY

摘要

Disclosed is an electrode composition containing a positive electrode active material including an iron compound and carbon, and a copolymer (P) of an acrylate and/or methacrylate and an a,ß-unsaturated nitrile compound. Also disclosed is an electrode which is composed of an active material layer made of such an electrode composition and a collector. This electrode can be produced by mixing the positive electrode active material, the copolymer (P), a solvent, and if necessary, a thickener using a mixer, thereby forming a slurry electrode composition having a solid content concentration of 40-90% by weight, and then coating the thus-obtained electrode composition over the collector and removing the solvent from the coating. Further disclosed is a battery comprising such an electrode.
