Beschreibung
Zusammenfassung:	The invention provides a positive pole, a manufacturing method of the positive pole and a lithium ion battery adopting the positive pole, wherein the active material of the positive pole is formed by mixing two lithium iron phosphate materials with different specific surface areas in a certain proportion. By adopting the technical scheme provided by the invention, compared with any electrode made from a single lithium iron phosphate material, the high multiplying power cycle life of the lithium iron phosphate electrode provided by the invention is greatly improved.
