RET TECHNOLOGIES TRANSFORM RECYCLING
The RET recycling process is a revolutionary solution. It is based on many years of experience in battery recycling. In an efficient, clean process, our technologies enable safe and effective recycling of all current lithium-ion batteries.
THE BATTERY CHALLENGE
Thinking about tomorrow today!
We are well aware of the challenge that the coming years will bring.
The production and marketing of lithium-ion batteries (LIB) is steadily increasing. The electromobility sector alone is growing exponentially. Added to this are all the so-called consumer batteries that can be found in smartphones and other electronic devices, for example. From today’s perspective, the amount of used batteries returned in Europe will increase eightfold by 2030. By 2040, 40 times as many used batteries will probably need to be recycled. This is why we want to make a significant contribution to establishing a circular economy for used batteries and thus conserve our planet’s limited resources.
Our Performance
By using the impact reactor, we guarantee a high yield and very clean black mass.
We already meet the legally required quotas for 2031.
The purity of our black mass enables efficient further processing in the hydrometallurgical process.
Our process is optimized so that it is not only economical but also environmentally friendly.
THE RET RECYCLING PROCESS: Discharge
Unloading - efficient, clean and safe
To ensure maximum process and work safety, the batteries are deeply discharged to 0 V. It doesn’t matter whether it’s entire memories, modules or individual cells.
The targeted residual discharge of the electrical energy still stored in the cells reduces the risk potential for the subsequent recycling process and improves the energy balance of the process by allowing both a return to the drying treatment and a change in direction to feed back into the network.
THE RET RECYCLING PROCESS: DRYING
Drying - innovative, precise and customizable
Depending on the size of the system, the batteries are then either inert or safely decomposed in a vacuum. The electrolyte is separated and recovered in a highly effective dryer specially developed for this application.
The discharged lithium-ion batteries are crushed in an inert atmosphere and thus broken down. The battery components are then fed into our vacuum drying process, in which the volatile electrolytes evaporate by generating negative pressure in combination with heat. These are then condensed out again and bottled in liquid form. Only the dried cell components are then sent for mechanical separation.
THE RET RECYCLING PROCESS: SEPARATION
Impact reactor - high-quality, effective and powerful
Only one unit is required for delamination of the electrode foils, for the agglomeration of metals and for separation of the black mass: The RET impact reactor.
By using the impact reactor, we guarantee a high yield and yet very clean black mass, even with previously untreated, dry production waste and scrap. The dry cell components are fed into the impact reactor. A special rotor ensures that the coatings are detached from the carrier films and the released Black Mass is discharged using an air flow and patented deflector wheel technology. Meanwhile, the housing parts, separators and metal foils are sphericalized and then separated from each other by suitable separation units and filled according to type.
