Zusammenfassung: | A method for recovering the valuable materials from energy storage devices (e.g., spent rechargeable lithium batteries, especially those batteries using nickel-based or nickel and cobalt containing cathode materials) are described. In particular, the proposed method applies carbonyl technology, also known as vapometallurgy, to regenerate pure materials which can be reused as raw materials for making active cathode materials for new lithium batteries.
Se describe un método para recuperar materiales valiosos de dispositivos de almacenamiento de energía (por ejemplo, baterías de litio recargables gastadas, especialmente aquellas baterías que utilizan materiales de cátodo a base de níquel o que contienen níquel y cobalto); en particular, el método propuesto aplica tecnología de carbonilo, también conocida como vapometalurgia, para regenerar materiales puros que pueden reutilizarse como materia prima para fabricar materiales de cátodo activo para nuevas baterías de litio. |
