Lithium-ion batteries are one of the common battery types. Therefore, there are many introductions on lithium-ion batteries on the Internet. In the forebel, small compass has an explanation of the cause of the explosion of lithium-ion batteries.

In order to enhance everyone's understanding of lithium-ion batteries, this paper will explain the lithium-ion battery-related content based on two points. First, the second is why lithium iron phosphate ion batteries are safe. If you are interested in lithium-ion batteries, you may wish to read it down.

First, the lithium-ion battery repairs the lithium-ion battery refers to a battery containing lithium (including metal lithium, lithium alloy and lithium ion, lithium polymer) in the electrochemical system. Lithium-ion batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium metal batteries are usually uncharacted, and lithium-containing lithium.

Lithium-ion batteries are widely used in hydroelectric, firepower, wind and solar power station and other energy storage power systems, uninterruptible power supplies of postal and telecommunications, as well as electric vehicles, electric bicycles, electric motorcycles, electric vehicles, military equipment, aerospace, etc. Lithium-ion batteries have been widely used in portable appliances such as laptops, cameras, mobile communications with their unique performance advantages. The large-capacity lithium-ion battery developed has been tried in electric vehicles.

It is expected to be one of the important power power supplies of electric vehicles in the 21st century, and will be applied in artificial satellites, aerospace and storage. With the shortage of energy and the pressure of the world's environmental protection. Lithium is widely used in electric automotive industries, especially the emergence of lithium iron phosphate material batteries, and promotes the development and application of lithium-ion battery industry.

The lithium ion battery does not contain a metal state, and it can be charged, then how is the lithium ion battery repair? (1) How to repair 1, the low temperature can make the electrolyte inside the lithium ion battery change, promote just just Chemical reaction after frozen batteries. Put the lithium-ion battery in a low temperature environment, the microstructure of the lithium film and the electrolyte surface of the lithium ion battery, and the interior of their intersection, resulting in the interior of the battery, and the leakage current is reduced. So after charging again, the time to wait for the time.

2, there is a method, remove the lithium-ion battery, put a week, will slowly consume the electricity, then first consume the electric power. Then all the rush, I estimate that your current charging time is definitely very short, after full, disconnect, repeated a few times, absolutely effective. (2) How to repair the lithium-ion battery 1, gently wipe the metal contacts on the lithium ion battery with clean rubber and other materials, and the metal contacts on the phone on the phone, which helps charging status and electricity.

2, will use the old mobile phone lithium-ion battery with automatic shutdown to cover it firmly, and we will try to pay three layers in the package, so that the battery is in a vacuum state. Then, the three-layer newspaper is added outside the plastic wrap, so that the lithium ion battery is completely sealed. The refrigerator is placed in the refrigerator, after 48 hours, the battery is removed, and the lithium-ion battery does not cause surface expansion or deformation due to freezing.

After a while, then charge. 3, let the lithium-ion battery close to the scrapped ion battery completely discharge, then recharge the activation battery. The specific method is to discharge the phone, which is to reach a deeper and reproduction by deepening internal energy, which uses some unconventional methods.

(3) How to repair 1, electric vehicle lithium-ion battery pack specification is 48V20AH, can be charged with 60V20AH battery charger; 2,48V12AH lithium-ion battery pack, 48V20AH battery charger charging repair. 3, repair the lithium-ion battery with dry cleaning water, the majority of electric car users realize that the electric car route is not far away, to add distilled water to maintain repair batteries. However, the pure water and various types of supplements sold in the market, the repair fluid has a short use of the battery, and the rear acceleration battery performance decreases, and scrapped in advance.

Second, the lithium phosphate ion battery why? Why is the safety? For electric vehicles, most people may have a little recognition, so we may wish to give an example to help us understand. Recently, the new electric car brand for the establishment of Biandi Dai Demler will be sold soon, and it is the lithium iron phosphate ion battery. Compared to the pre-manganese acid lithium-ion battery, the lithium phosphate ion battery is not too large, about 100-110Wh / kg, but its thermal stability is the best in the car lithium ion battery.

When the battery temperature is at a high temperature of 500-600 ¡ã C, its internal chemical composition begins to decompose, and the lithium-ion battery of the same lithium ion battery is in an unstable condition of the internal chemical component at 180-250 ¡ã C. In other words, the safety of lithium iron phosphate ion batteries is premier in a lithium ion battery, and is that in this way, it has become one of the primary categories of electric vehicle batterie.
