Magical: Identify new lithium-ion battery packs and waste lithium-ion battery packs. As an old driver in a lithium-ion battery pack industry, I have learned how to distinguish the new old and old. Lithium-ion battery packs will be recovered after the service life arrival time, and the ladder is used, if the recycling and improper treatment will cause huge harm to the environment.
So, how do we identify new and old lithium-ion battery packs when buying? Xiaobian will share a small trick with you. How to distinguish the new old lithium-ion battery pack? According to German media reports, recently in the German website, a small suggestion: in order to determine if a lithium-ion battery bag is an air battery that should be abandoned, people can put the battery from the ground 20 cm from the ground Throw it down, if the rebound after the battery is in contact with the ground, the battery is an empty battery. If the battery is not populated, it proves that it is a new battery.
This incident has caused interest to scientists. They reopened verify in the laboratory, using slow-lens camera to record air batteries and new batteries from the slight track falling from the table. The results show that the height of the empty battery is determined that the height of the ground is higher than the high height of the new battery.
In order to further verify the rationality of the statement, American researchers have conducted a more in-depth study. Researchers let two lithium-ion battery packs fall in an organic glass tube and measure the first and second rebound height during this process. In addition, researchers have added several control groups in the experiment: 70%, 80%, and 90% battery, respectively.
In the end, the experimental results show that whether it is ordinary disposable battery or a lithium-ion battery, as long as there is half of the battery, it can be bounced with a height, but it is highly different. Researchers explained this phenomenon that the positive electrode of household batteries is composed of zinc elements, and these zinc elements are present in the cell gel. Battery gel reduces the charged battery by the impact of the ground, so the charged battery is often bounced by the ground.
In the process of battery discharge, a large amount of zinc elements contained in the battery forms zinc oxide and oxygen, which is a rigid substance that enables battery rebound height higher. At the same time, researchers also said that this experiment cannot be used as a standard that the battery is thrown, the experimental real meaning is how to resolve waste lithium-ion battery packs and new batteries. Speaking of the waste lithium-ion battery packs have a recycled value? How to recycle and reuse? The lithium-ion battery is important from the outer casing, the positive electrode, the electrode, the electrolyte and the diaphragm, containing more copper, aluminum, lithium and other elements utilized Big.
After the recycling, it is still very useful to use value, but also prevent environmental pollution. Waste lithium ion battery pack recycling method: commonly used waste lithium ion battery pack resource method includes chemical method, biological method and mechanical physics. Compared to wet and fire, mechanical physics does not need to use chemical reagents, and lower energy consumption is a environmentally friendly and efficient method.
Scientific effective treatment for waste lithium ion battery packs, not only has significant environmental benefits, but also has good economic benefits. Lithium-ion battery packs have been widely used in mobile phones, laptops, digital cameras, models, electric toys, electronic instruments, electric vehicles and hybrid vehicles, etc., for the lithium ion battery pack prospects.
Lithium-ion battery pack will always go on your own, follow the times, continuously develop new technology, supply to your best latest products. .
