Cathode Including a Non Fluorinated Linear Chain Polymer as the Binder, Method of Making the Cathode, and Lithium Electrochemical Cell Containing the Cathode.
Abstract
A cathode suitable for use in a lithium electrochemical cell is made from a mixture of active cathode material, carbon, and non fluorinated linear chain polymer by a method including the steps of; (a) dissolving the non fluorinated linear polymer in a non polar solvent at a temperature near the melting point of the polymer, (b) adding the active cathode material and carbon and evaporating the solvent, and (c) grinding the dried mixture into a fine powder and making it into a cathode by pressing the powdered mixture onto both sides of an expanded metal screen and then cutting to the desired dimensions. The cathode can be combined with lithium as the anode and a solution of 0.8 mol/cu dm LiAlCl4 in a mixed organic solvent of 24 mass percent 4-butyrolactone in 1, 2 dimethoxyethane as the electrolyte to provide a mechanically stable, relatively inexpensive lithium electrochemical cell having good cell performance.
