Description

Power battery pole piece powder removing equipment

Technical Field

The utility model relates to power battery recovery plant field, it is specific that power battery pole piece takes off whitewashed equipment.

Background

The national policy greatly promotes the popularization of electric vehicles, and the power battery is used as an energy storage device of the electric vehicle, so that after the life cycle is finished, the power battery needs to be reasonably disposed and recycled, the resource shortage is relieved, and the environmental pollution is eliminated.

After the waste power batteries are crushed, positive/negative active substances (black powder) adhered to the surfaces of aluminum/copper foils serving as current collectors of the power batteries need to be effectively separated. Because the active substance is adhered to the surface of the current collector by adopting an organic adhesive, most of the separation processes are high-temperature incineration to remove the adhesive, and then aluminum/copper foil and black powder are separated by a rotary vibrating screen. However, the binders are mainly PVDF (polyvinylidene fluoride) and CMC (carboxymethyl cellulose), the high-temperature incineration can bring fluoride smoke pollution, the production energy consumption is high, the high-temperature incineration process can not ensure complete separation of aluminum/copper foil and black powder, and the black powder yield still needs to be improved through a powder removing process.
