Claims8
A method for separating or recovering materials from electrodes, the method comprising:
- providing a substrate including a coating thereon, the substrate comprising a carrier material of a first electrode;
- producing accelerated CO2 snow particles by snow blasting;
- exposing the coating to the accelerated CO2 snow particles and selectively removing coating material from some areas of the substrate, a first portion of the coating being removed while a second portion of the coating remains on the substrate;
- after exposing the coating to the accelerated CO2 snow particles, compacting the coating for production of the first electrode;
- producing purified and/or prepared coating material from the coating material removed from the substrate;
- and
- utilizing some or all of the purified and/or prepared coating material to coat another carrier material for production of a second electrode.
