About advantages and disadvantages of polymer cells

Polymer battery is also a kind of batteries. Unlike 18650 battery with liquid electrolyte, polymer is a gel electrolyte, so it is different from lithium ion battery, and distinguish from 18650 batteries.

It is widely used polymer batteries, polymer batteries currently many mobile devices are used for power supply, especially the most cell phones and mobile power supply.

So what are the strengths and weaknesses of the polymer batteries?

Advantages -

1, high safety, cannot deny the fact that the relatively polymer batteries a bit higher than 18650 batteries for safety, or the dangers of destructive, in general, most polymer batteries is the bulge, rupture, and burning, there is no direct destructive blast.

2, the capacity is larger: compared with the general battery, the capacity of the polymer is relatively large, 100/115 mAh/g g capacity.

3, flexible shape: due to the polymer using aluminium film packaging, has no definite shape, so can produce flat batteries, or according to the needs of different customers, customize the different shapes of batteries, meet the needs of different, very flexible.

4, fast charging: compared to other types of batteries, polymer batteries charging speed, discharge current is relatively stable.

5 is relatively light in weight, because want to use shell at protection, polymer batteries are lighter than the same volume of 18650 batteries.

Disadvantages -

1, high cost, compared with those of other batteries polymer battery cost is almost the highest, and it is concentrated in the difficult to reduce the electrolyte, high cost has become a major factor restricting the development of polymer battery.

2, there is no fixed model: due to the variability of shape, although more can meet the need of the market, but also led to no unified model, there is no change, thus lost the sustainability of the market.

3, Copycat serious: as the polymer battery market prospect is good, but the manufacturing cost is high, so a lot of 18650 batteries appear on the market after flattening the stronghold into polymer batteries, once the copycat crisis.

4, with low energy density: compared to other lithium ion battery, the energy density of the polymer is relatively low, resulting in a lot of manufacturers in order to increase the capacity of the compression hard security protection.
