With the development of the times, people's pace of life is getting faster and faster, and urban traffic congestion is getting more and more serious. It is very important to choose an appropriate way of travel. A simple and portable means of transportation is the best choice. However, riding a bicycle is too tiring. Electric scooters and balance bikes are popular products of transportation, which are popular among young men and women. Today, let's compare the balance car and electric scooter. Which car is more suitable for transportation?

Lithium iron phosphate battery is a lithium ion battery with lithium iron phosphate (LiFePO4) as the cathode material and carbon as the cathode material. The rated voltage of the single battery is 3.2V, and the charging cut-off voltage is 3.6V~3.65V.

Is there any special reason for the use of aluminum foil and copper foil for the current collection of positive and negative electrodes? Is there any problem with using it in reverse?

There are two basic processes of internal short circuit of battery caused by metal foreign matters, as shown in Figure 1. In the first case, large metal particles directly pierce the diaphragm, causing a short circuit between the positive and negative electrodes, which is a physical short circuit.

In terms of materials used, the positive electrode materials of polymer lithium ion batteries are divided into lithium cobalt oxide, lithium manganate, ternary materials and lithium iron phosphate materials. The negative electrode is graphite, and the working principle of the battery is basically the same. The important difference between the positive electrode materials of polymer lithium ion batteries lies in the difference of electrolytes. Liquid lithium ion batteries use liquid electrolytes, and polymer lithium ion batteries use solid polymer electrolytes instead. This polymer can be dry or glued. At present, most of the polymer gel electrolytes are used.
