Cathode material for secondary battery and manufacturing method of the same

摘要

Disclosed are a cathode material for a secondary battery, and a manufacturing method of the same. The cathode material includes a lithium manganese phosphate LiMnPO4/sodium manganese fluorophosphate Na2MnPO4F composite, in which the LiMnPO4 and Na2MnPO4F have different crystal structures. Additionally, the method of manufacturing the cathode material may be done in a single step through a hydrothermal synthesis, which greatly reduces the time and cost of production. Additionally, the disclosure provides that the electric conductivity of the cathode material may be improved through carbon coating, thereby providing a cathode material with excellent electrochemical activity.
