Abstract:
1. A method for producing an electrode material comprising: spraying and drying a slurry so as to produce a granule; firing the granule in a non-oxidizing atmosphere at a temperature of from 500 to 1000° C., wherein the slurry includes an electrode active material or the precursor of an electrode active material and organic compounds selected respectively from at least two groups of the following group A, group B and group C: and Group A is polyvinyl alcohol, polyvinyl pyrrolidone, cellulose, starch, gelatin, carboxymethyl cellulose, methyl cellulose, hydroxymethyl cellulose, hydroxyethyl cellulose, polyacrylic acid, polystyrene sulfonic acid, polyacrylamide and polyvinyl acetate, and Group B is glucose, fructose, galactose, mannose, maltose, sucrose, lactose, glycogen, pectin, alginic acid, glucomannan, chitin, hyaluronic acid, chondroitin and agarose, and Group C is polyether or multivalent alcohols except organic compounds belonging to the groups A and B; and wherein the electrode material comprises primary particle of electrode active material coated with thin film-like carbon having a thickness of 50 nm or less.
