Mobile power energy storage lithium battery manufacturers explain the energy storage lithium battery cells in detail

With the popularity of large-screen smartphones, the battery technology itself has become a bottleneck, and fewer and fewer mobile phones have a standby time of more than a day. This gave birth to a new product category - power bank, or power bank (collectively referred to as power bank).

With the advancement of technology, the 5000mAh power bank is still the starting point. Power banks of 8000, 10000, 15000 and even 20000 mAh abound. The current mobile power market is very chaotic. From tens of yuan to hundreds of yuan, various brands are dazzling (there are hundreds of brands in the power bank category of a D-level e-commerce company in China). But there are still many doors in the power bank. Such as its appearance, there are round, flat, long, square, sheet and even plush toys! There are also differences in its standards, such as the airport says watt-hours instead of the milliamps we usually say. There are also more and more functions, such as storage, wireless routing, card reader functions, and more.

The most important thing in discharge efficiency is the battery. What is it?

The current mobile power cells are generally divided into 18650 cells and polymer lithium-ion cells.

Their appearance is also very recognizable.

Cylindrical, heavier power banks are generally 18650 batteries.

The size and appearance of polymer lithium-ion batteries can be customized. For example, some very thin, weird-looking, flaky power banks.

Now there is a saying that the 18650 battery is lower than the polymer lithium ion battery, I always feel that there are several rechargeable batteries in it. This is real?

  of course not!

There are 18,650 batteries in a Tesla. Do you think it would be bad? Batteries are divided into three grades: A, B, and C. If they are all A-level cells, the discharge efficiency of the cells under the same mA is almost the same. This statement is mainly a marketing strategy of manufacturers selling polymer lithium-ion batteries and attacking opponents at high prices. Everyone needs to understand this.

So the so-called myth that the battery is better does not exist. What matters is the rating of the battery. Be sure to find a brand from a big manufacturer to ensure the quality of the battery.
