Perfect recycling of damaged batteries for you

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. Visit for perfect support.



Toxic batteries


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.


Commodity shortage?


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.

The Birth and Gain in Bitcoin Now

On October 31, 2008 was born bitcoin, the first decentralized virtual currency. Ten years later, the main cryptocurrency nourishes a complex ecosystem but is still struggling to convince in the economic sphere.

From its first evocation in 2008, bitcoin carries a political vision.

Cryptocurrency and wine: do not use these platforms to invest!

Appeared in a white paper written by Satoshi Nakamoto, a pseudonym whose identity behind remains unknown, the stated goal is to use a decentralized registry system, the “blockchain”, to “make online payments directly from a third party to another without going through a financial institution “.

This ambition is then fueled by the bankruptcy of the Lehman Brothers bank, which took place a month earlier, which has discredited the “traditional currencies where small elite of bankers enriches a lot, establishes the monetary rules and imposes them on everything in the world, it was stated by whom, who founded the first European bitcoin exchange platform in 2011. If you have more queries about the same, you can visit now.

After its creation, bitcoin evolves for several years off the radar of the general public, only interested in geeks or money launderers.

In 2013, bitcoin, which was virtually worthless at first, however, exceeds $ 1,000 and begins to attract the attention of financial institutions. “The European Central Bank evokes a dangerous operation on the Ponzi”, when the then boss of the Federal Reserve, Ben Bernanke, salutes his potential.

A turbulent childhood

A few months later, however, the cryptocurrency must face its greatest crisis with the hacking of the MtGox platform, where up to 80% of bitcoins in circulation traded. The price collapses and it will be necessary to wait more than three years before it returns to its level of end 2013.

The total capitalization of bitcoin temporarily exceeds $ 300 billion, according to the specialized site Coinmarketcap. That of all cryptocurrency even exceeds 800 billion in early January 2018, before the bubble burst and gradually reduces the value of bitcoin around 6,400 dollars.

The age of Reason?

If the original idea was to make bitcoin a means of exchange, the maximum number of observers distinguishes that it use to be used mainly as a store of price or speculation instrument, because of its volatility.

It takes 20 years for a network technology of this type to take its place completely, justified by the founder, who is banking on the advent of “lightning” to increase the speed of transactions, while the network is today. He is able to handle five to ten transactions per second (against several thousand for the Visa card operator).

In recent months, the cryptosphere has also been shaken by the possible creation of an index fund backed by bitcoins, which would boost investments. A highly anticipated announcement is expected shortly from the US Securities and Exchange Commission.
