State-of-the-art storage elements
The sun does not always shine, and the wind blows irregularly. However, a massive solar and wind system is far from suitable for every application. That's why you need rechargeable storage elements such as batteries and batteries, which will hopefully be recharged later in the application from renewable energy sources. Batteries are found in countless mobile systems. As batteries including protective circuits, for example in electric cars, e-bikes, and more recently also in e-trottinettes. Soon, each new product will have an E- before the type designation. Storage elements everywhere! Most of all, it's in the mobile phones that virtually every person carries around with them all the time. Here it is mainly the well-known lithium-ion batteries and batteries. In the industry, the Li-ion packs are manufactured exactly to specific customer needs. Here it is definitely worth contacting experts in this field. The devil is in the detail here, too.
Tips for mobile phone users
With all the countless mobile phone types, you should know that they are usually recharged within 1000 to 1500 cycles. Fortunately, this will be enough for a few years. But even before that, the loading capacity is constantly reduced. Also, it is not absolutely necessary to charge the mobile phone or other lithium-ion applications again and again to 100%. Experts recommend the range from about 30% up to a maximum of 80%. You can also save money by turning on the power-saving mode. Performance is slightly reduced, but in the mobile phone background, the consumption-intensive apps, etc. are turned off. The user will also save power if the background lighting is not fully turned on. And those who do not buy a new mobile phone every year are now serving the environmental protection that is now in everyone's interest.
Who actually invented the lithium-ion battery?
Everyone knows in the meantime the electric car manufacturer Tesla. This has taught the conventional German luxury car producers the fear. In Switzerland, in the upper segment such as the Mercedes S-Class, BMW 7 and the like, significantly more Teslas have been sold than from those models. Tesla finally comes with smaller, cheaper models on the market. In the meantime, the Europeans have also woken up and now also come with e-models in the price range middle. High time, otherwise a major worldwide trend simply overslept. China relies heavily on e-mobility, not least because of the filthy air in big cities, where the sun shines through only dimly, if at all, and people with face masks walk around. A terrible idea for us.
Thousands of lithium-ion batteries are installed in the lower part of the Tesla S in the picture and provide for enormous acceleration, extremely low center of gravity and for a distance of around 500 kilometers and more. Not only in the car such batteries are installed, but in countless mobile devices such as mobile phones, laptops, tools, bicycles and now even in small scooters.
Who actually invented the Li-ion batteries?
The Japanese chemist Akira Yoshino worked in the early 1980s on a specific technology that was still in need of improvement. His goal was to produce the smallest possible battery, which also has a high energy density. In 1985, Yoshino and his colleagues were granted the patent for the first lithium-ion battery with truly huge potential. The energy density is increasing now and Yoshino expects in the future with a load time of only 5 minutes!. He continues to research on a solid-state battery that can not burn, among other things! At the Paul Scherrer Institute in Würenlingen, the local researchers are on the front line. We are eager to see what happens. In English, the general battery technology is a real "game changer" for all of us!

Recycle of disused batteries and rechargeable batteries
The recycling of batteries
The Accutron AG in Bassersdorf near Zurich has been for many years a professional supplier of industrial batteries and batteries of all kinds. It also endeavours to notify its customers of the prescribed recycling of the disused batteries. The reason: Batteries and accumulators contain numerous valuable raw materials which can be recycled. They also contain some harmful heavy metals. In Switzerland, battery recycling is carried out by the Ordinance on Environmentally hazardous substances, substance regulated and Accutron is a partner of INOBAT. (www.inobat.ch)
The different battery types such as zinc coal, zinc air and alkaline batteries; The nickel-cadmium batteries, the nickel-metal hydride batteries as well as the very often used lithium batteries in mobile devices are technically in different ways recycled.
Here, now more specific to the lithium batteries/accumulators. These Li-ion products contain metals such as copper and aluminium and – depending on the active material – the transition metals cobalt and nickel.
The deactivation and discharge of the battery, especially for larger batteries from electromobility, is done by various procedures: dismantling the battery-system, mechanical processes such as shredding, sorting and sifting. Hydrometallurgical processes as well as pyrometallurgical processes, both for material separation. Specific dangers of Li-ion products are electrical and chemical hazards, fire hazards and interactions between them. Therefore, there are extremely strict transport regulations.
A specialized Swiss recycling company
The Batrec Industrie AG in Wimmis is for instance a company of the Veolia Group and specializes in sophisticated recycling services. It processes for customers worldwide batteries, mercury-containing products, activated carbon filters and Spent Catalysts and offers high purity mercury as a raw material. Batrec makes waste a resource again and thus ensures closed material cycles. The company is committed with sustainability; As a Swiss company it applies highest standards in terms of environmental protection and safety.
