POSITIVE ELECTRODE FILMS FOR ALKALI METAL POLYMER BATTERIES AND METHOD FOR MAKING SAME |
摘要 |
A process for extruding a thin positive electrode sheet having at least 40% /wt of solid content for a lithium polymer battery through a single or twin screw extruder is disclosed as well as a positive electrode sheet produced therefrom. A mixture of active cathodic intercalation material, lithium salt and electronic conductive material is mixed with a polymer of the polyether family in a ratio of at least 40% of total weight into the mixing chamber of an extrusion machine and extruded through a classical sheet die into a thin cathode sheet or film onto a substrate in sheet form. |
