As a battery production brand manufacturer for more than 10 years, we have a deep understanding of the development of the charging treasure cell. The following is a good choice for the charging treasure cell.

1, which is the best charging treasure cell

    811 soft pack polymer lithium battery, but none of the current charging bank is using this kind of battery, because this kind of battery has high energy density, the price is more expensive, if it is made into a charging bank, the product price will be more expensive, not many consumers can accept the higher price, so the charging bank manufacturers dare not use 811 soft pack polymer lithium battery as a charging bank cell.

2, the current mainstream charging treasure cell

    With the improvement of people‘s living standards, the pursuit of small volume, large capacity, light weight and support for fast charging demand will continue to improve, now the charging bank on the market is also moving towards these directions, and can achieve these, the soft pack polymer lithium battery is the most suitable, especially the battery produced by the laminated process, more suitable. Therefore, most of the current battery cell is soft pack polymer lithium battery.

    Because soft pack polymer lithium battery and 18650, 21700, lithium iron phosphate battery (lithium ion battery includes: 18650, 21700, lithium iron phosphate battery, lithium polymer battery, etc.) these batteries, the energy density is relatively high, it is easier to meet the needs of large capacity, small volume and light weight; However, 18650 and 21700 belong to the cylindrical steel shell batteries, which are not only fixed in shape and volume, but also relatively bulky, and not very suitable for the charging bank cell. As for the lithium iron phosphate battery, due to its relatively small energy density, the weight and volume of the battery will be larger and heavier than that of the lithium polymer battery to achieve the same capacity.

3. Supplement other knowledge

    We need to pay attention to is: when choosing the charging treasure cell, even if it is the same polymer lithium battery as the cell, because different brands of cell manufacturers manufacturing technology level is different, they will be different in quality performance, so we try to choose those brand reputation (public praise) good manufacturer‘s products.
