Mobile power election polymer batteries or lithium batteries really good
18650 batteries: lithium-ion battery is a lithium battery improved products, after years of development, lithium-ion battery technology is relatively mature, high-volume production has been so that its manufacturing costs are very low, so the lithium-ion battery at the price It is more than the lithium polymer battery advantage.That is why most of the current notebook computers and other equipment will use this battery.Now mobile power is the most common use of steel 18650 battery, with a high safety factor, production technology Has been very mature, and the price is cheaper than the polymer battery, accounting for most of the lithium battery market share, the most common in the laptop battery.
Polymer batteries: the general use of soft aluminum-plastic composite packaging film. The internal semi-solid polymer. Smooth performance, high efficiency, small internal resistance. Safety performance is better, there are over-current, overvoltage protection device. Life cycle charge and discharge cycles of about 500. But the polymer batteries are usually wrapped with tin foil paper is easy to deformation, impatient impact, because the manufacturer of different over-voltage protection quality is good and bad and so on.
In fact, the polymer batteries are also lithium batteries. Lithium batteries are divided into: liquid lithium-ion batteries and polymer batteries two. As for the two batteries who are more stable, it can not be generalized, mainly to see the technical level of manufacturers.
