There are still many skepties around the massive pure electric plans, many places. But the feasibility of the overall plan, as well as the attitude of optimization while each of the links, is also known for reference. One of the very important links is the battery recovery plan.

This project is currently falling in Salzgitter, from 2020, annual recovery of 1200 tons of lithium-ion batteries, about 3000 cars] will decompose and classify recycled batteries, and some can continue to use Ladder utilization program. The most important thing is to dismantle the battery system entering the EOL life cycle, and the current recovery is 53%. As shown in the figure below, the entire analysis process is important as the front and later sections.

Front section: Demolition according to the battery system contrary to the installer, the upper housing, cable, control unit, and aluminum housing are disassembled: put the battery module into the pulverizer, cut the entire module, then Drying, screened by special machines analysis showing black powder (nickel, manganese, cobalt and lithium), and finally analyzes steel, diaphragm, aluminum and copper by separating mechanical analysis. The process of increasing the entire recovery: The first stage (53%): It is this stage, important recycling aluminum, copper wire, electronic components, nickel, cobalt and copper foil. The second stage (72%): For the material of lithium, manganese, it is also targeted, as well as the third stage of aluminum foil, connector, plastic, etc.

(97%): extend to negative electrode graphite, electrolyte, unique It is the diaphragm that is used without the method.
