Risk free battery recycling essential now

The transition from landline to mobile has given a huge boost to the development of electric storage. Electrification everywhere – also in mobility. The core element of electric cars is not just the power, but also the memory (battery or rechargeable battery), which absorbs this energy and gives it to the vehicle.

Imagine the battery storage of the electric car like an oversized cell phone battery. The terms “accumulator” and “battery” are colloquially used side by side and often synonymous. Although it is strictly speaking wrong. Rather, it should read: A battery is a primary cell and can not be charged. A rechargeable energy storage such as the battery in the electric car is not a battery, but a secondary cell.

Strictly speaking, what drives the electric car, physically correctly designates a “traction battery from a few to thousands of parallel and serially interconnected accumulator cells” (Wikipedia) – mostly installed in the vehicle floor and many, many kilograms. From the Kinsbursky scrap yard get the opportunities now.

Both laymen and experts speak of rechargeable batteries, sometimes of batteries, and agree: the success of electro mobility ultimately depends on this high-tech component, which is as expensive as it is sophisticated, and above all on the cost-effectiveness, efficiency and everyday usability of the electric car.

Electric car without battery? Nothing works without lithium ions

Almost always, the battery is a lithium-ion technology. Batteries differ depending on the manufacturer of the materials used. Common to them is that they use lithium, both in the electrodes – ie anode and cathode – as the electrolyte itself.

The battery is the most varied, sometimes contradictory requirements: Cheap it should be. This helps the most likely to increase the number of units. Lithium should not be running low, at least for now. A battery should be light , but this does not correspond to its nature. For this reason, research has long ago been testing other materials , for example plastics and glass, sulfur and silicon.

Solid batteries may be several times more powerful than those with a liquid membrane. All announced new batteries charge faster , last longer and are safer. Solid state batteries, so the term for solid batteries, could be used even at low temperatures and cheaper to produce – so very close to the ideal battery.

In development: load more often, faster, cheaper

Lithium iron phosphate batteries are widely used in China today – rugged models that can handle up to 10,000 charging cycles. They are temperature stable, but with lower energy density than European or Japanese lithium-ion batteries.

Researchers are currently testing battery types that can handle up to 15,000 charge cycles without significant capacity loss. However, compromises have to be made elsewhere: in terms of energy density, charging time, weight or lifespan.

Bosch wants to double the charge capacity of its batteries by 2020, so that a range of 400 kilometers is achieved.
