Since energy sources such as solar energy and wind energy have always had intermittent “faults†and are difficult to store, they have never been more important than lithium battery storage systems. And as many materials on the earth used to make high-performance batteries become less and less, the current battery becomes more and more expensive.
Maybe you didn't find this problem, but think about it. Seven or eight years ago, when you bought a cell phone, it was mostly equipped with two batteries. Now, whether or not it is because of the reason that it is not easy to dismantle, basically there is only one piece, which can also explain from the side that the battery is becoming more “expensiveâ€. Now, researchers at the ETH Zurich have created a new battery system that will have better performance than lithium batteries and materials that are cheaper.
Simply put, this is a battery made of nanocrystals made of iron sulfide, because it looks golden, so it is also called "fool gold." To be precise, the four elements used in the battery's manufacturing materials are iron, magnesium, sodium, and sulfur. The content of these four elements on the earth ranks fourth, sixth, seventh, and fifteenth, respectively. It can be said that these four elements are quite rich in content and extremely easy to exploit.
At present, the battery of this hybrid material has been tested in the laboratory, and after 40 complete charge and discharge cycles, its performance has not changed! For the average person, 40 full charge and discharge is almost enough for one month, which means that after one month of use, your battery is almost exactly the same as the new one, without any aging, indicating that such a battery has A long service life.
Currently, researchers at the ETH Zurich continue to develop the battery. It plans to be pioneered in relatively large projects, such as nuclear power plants. But in the near future, it will also be used in such small areas as mobile phone batteries, perhaps, the era of lithium batteries is not far from the end.
Galvanized wire is divided into hot dipped galvanized wire and cold galvanized wire (Electro Galvanized Wire). Galvanized wire has good toughness and flexibility, the maximum amount of zinc can reach 350 g /sqm. With zinc coating thickness, corrosion resistance and other characteristics.
