  "textContent": "The present invention provides a novel method capable of recovering Ni and Co from a battery waste containing Ni and Co while adjusting an Ni/Co ratio. The method for reproducing the positive electrode material according to the present disclosure includes a step of leaching Ni and Co, using an ammonia aqueous solution containing ammonia and ammonium sulfate, from a battery waste containing Ni and Co into the ammonia aqueous solution. Herein, oxygen is fed to the ammonia aqueous solution in the leaching.",
