Many small brands and manufacturers of power bank scramble the market of mobile power supply, so there are many fake and shoddy products, resulting in poor experience of consumers in the process of using mobile power supply. The most important core component of mobile power supply is the cell, so today we focus on the analysis of the cell of mobile power supply.
1. Composition of mobile power cell
Mobile power supply is mainly composed of three parts, which are cell circuit board and shell cell. As the core part of mobile power supply, it is composed of positive and negative materials, electrolyte and diaphragm, which is one of the important factors affecting the charging speed and service life of mobile power supply. So the quality of mobile power mainly depends on its cell quality.
2. Classification of mobile power cell
At present, most of the mobile power cells on the market are lithium-ion batteries. According to the classification of materials, we can roughly divide them into liquid lithium-ion batteries and polymer lithium-ion batteries. The common battery categories in the market are 18650 cells, polymer cells and lithium iron phosphate cells. These kinds of cells are commonly used by major manufacturers, whether from the price, quality, life, safety, etc., comprehensive comparison is more prominent lithium-ion batteries.
The cell is the most critical part of the whole mobile power supply, so the quality of the cell directly affects the quality of the mobile power supply. In order to improve consumers' sense of using the mobile power supply, the quality of the cell will be strictly controlled, so as to improve the safety of consumers in the use process.
