  "textContent": "The invention relates to a process for treating all the end-of-life accumulator and battery types except the alkaline, zinc-carbon ones and lead accumulators. The process comprises a first phase of physical operations and a second phase of chemical operations which all together allow the recovery of copper and plastic materials typically contained in nickel-metal hydride accumulators, lithium ion batteries and accumulators, primary lithium batteries. The process is characterized by the use of a purification operation by means of a solvent which allows obtaining lithium products (Li 2 CO 3 ), cobalt (Co/CoSO 4 /CoCO 3 ) and nickel (Ni/NiCO 3 ) with a high purity grade.",
