POSITIVE ELECTRODE MATERIAL FOR LITHIUM CELL AND METHOD FOR PRODUCTION THEREOF.

摘要

A positive electrode material for a lithium cell which comprises an active substance containing any of lithium phosphate, lithium-cobalt phosphate, cobalt oxides and lithium-cobalt oxide more than 0.1 mol of cobalt and more than 0.2 mol of phosphorus per mol of lithium; and an organic polymer binder. The electrode material is shaped into a sheet, which has high utility and producibility without deteriorating the performance of the novel active material having the composition described above. The sheet material for the positive electrode of the lithium cell is produced by spreading solution of the organic polymer containing powder of the active substance on a long support sheet and drying it. The sheet material for the lithium cell can be obtained stably and efficiently by a continuous process.
