Abstract: A positive electrode material for a secondary battery and a method for manufacturing the same are provided, in which manganese fluorophosphate containing lithium or sodium can be used as an electrode material. That is, a positive electrode material for a lithium/sodium battery is provided, in which intercalation/deintercalation of sodium/lithium ions is possible due to a short lithium diffusion distance caused by nanosizing of particles. Furthermore, a positive electrode material for a lithium/sodium battery is provided, which has electrochemical activity due to an increase in electrical conductivity by effective carbon coating.
