The present invention provides a method for recycling a positive electrode material for secondary batteries that can not only safely separate positive electrode materials included in waste batteries without by-products such as acid waste and the like, but also recycle the rapidly increasing amount of waste batteries through a simple and efficient process, thereby significantly reducing social and economic costs. La présente invention concerne un procédé de recyclage d'un matériau d'électrode positive pour des batteries secondaires qui peut non seulement séparer de manière sûre des matériaux d'électrode positive compris dans des batteries usagées sans sous-produits tels que des déchets acides et similaires, mais également recycler la quantité augmentant rapidement de batteries usagées par un procédé simple et efficace, ce qui permet de réduire significativement les coûts sociaux et économiques.
