As far as the batteries are concerned, one encounters much ignorance and half-truths in this country. From toxic ingredients to batteries that need replacing after a short while, etc.
Today’s batteries are much more durable and at the same time less problematic than is generally assumed. And there is even a life after the electric car.
Lifespan of batteries
Charging and discharging the battery will cause a reduction in capacity over time. An effect that is known, for example, from the smartphone. Compared to mobile phones, however, higher-quality batteries are used in the electric vehicle, which are also monitored and monitored by a special battery management system. In electric cars with advanced technology (such as Tesla Model S, X and 3, BMW i3, etc.) s additionally ensures a heating or cooling that the batteries are always in an optimal temperature window.

It is often claimed that lithium-ion batteries contain so-called rare-earth metals, that they are also poisonous and thus represent a real environmental problem at the time of disposal. The fact is that the lithium-ion battery does not contain any rare earth metals, but instead unproblematic materials such as cobalt, nickel, lithium, etc. exists.
Toxic and dangerous, for example, the lead-acid batteries, as they are known as starter batteries from conventional vehicles. As a traction battery (= energy storage, which is used to drive electric vehicles) are lead-acid batteries due to their low energy density and high weight out of the question.
Second Life, Recycling and Disposal
This works as follows: If too much energy is produced compared to the demand, the excess current is used to charge the battery. If sudden peak demand arises, the extra energy required can be provided from the batteries.
The electricity utilities of the canton of Zurich (EKZ) have put into operation such a storage system in Volketswil at the beginning of 2018. With a storage capacity of 7.5 MWh, it is currently the largest storage battery in Switzerland.
If the battery is really exhausted after a few years, then it is not just “waste”. Instead, the batteries are recycled, where about 90% of the materials can be reused to make new batteries. The battery factory “Gigafactory 1” from Tesla in Nevada / USA, for example, has been designed so that old batteries can be produced as automated as possible.
Many people claim that there is too little lithium for a global shift to electric vehicles.
First, it should be noted that the lithium-ion batteries contain relatively little lithium, despite the prominent placement in the naming. Specifically, one assumes about 150 grams of lithium per kWh capacity. So while a large battery such as the Tesla Model S weighs about 600 kg, the lithium only makes up about 10 kg. For smaller vehicles, it is just about 3-5 kg.
