Study: Batteries need more recycling standards

Study: Batteries need more recycling standards-batteries

Slowly but surely the E-car comes in drive. Also and especially in Germany. To take potential customers the shy, the manufacturers advertise with multi-year warranties for their batteries. But what comes afterwards – a second battery life? Professionals already expect a billion market. Studies according to “2nd Life” batteries with up to 1000 gigawatt hours for 2030.

But skepticism is mixed in euphoria. Too different are the many systems, it says, too little standardized the recycling, too little networks the market participants. For a long time, there were hardly incentives to worry about the later use during development. Also missing partly norms that take into account aspects of disassembly and “re-use” in the manufacture of the batteries.

The company PEM MOTION – a spin-up of the chair “Production technology for electromobility components” at the RWTH Aachen – has now published a study for reuse and reuse of e-auto batteries. Vehicle and battery manufacturers were included as well as plant manufacturers, suppliers and start-up companies in the field of stationary storage. Conclusion: Battery is not the same battery.

For the study, according to PEM, several battery types of various vehicle manufacturers and different phases of the lifecycle were examined. The team has found that the residual value of a battery – unlike the internal combustion engine – do not let go by the mileage alone. Above all, the usage history and the calendar age practiced a great influence on the condition of the discarded batteries. For example, charging status and temperature would have a greater impact than the fundamental aging.

For the investigation, numerous batteries have been remunerated with different properties. Result: “For all products a re-assembly is possible, but a standardized concept is currently not recognizable,” says Professor Achim Kampker, Head of the RWTH Chair PEM. To achieve this, many aspects would have to be considered in development and production – for example in the bonding of different parts.

“The sooner and better we can answer the questions about the reuse and reuse of batteries, the more environmentally friendly the e-mobility and the higher will also be your social acceptance,” says Kampker. Necessary is an even better circular economy. Even today, one is technically able to recover up to 95 percent of the important materials.

The study of the study developed according to own information a model, with the help of which can be calculated on the basis of the current sales figures scenarios, costs and benefits and processes for disassembly and recycling. When quantitatively, the capacity could be scaled. If the assumptions were confirmed by practical implementation, this type of automation can also be profitable for the recycling industry, it means.

  1. Alone at the Kona, around 78,000 batteries are now exchanged worldwide (in Germany around 11000 via KBA callback).
    These batteries are not so easy reusable.
