Mobile power supply to choose polymer lithium ion battery good or 18650 batteries
safe use polymer lithium ion battery charging treasure is good or 18650 lithium batteries, polymer battery actually on cost could be expensive. The type 18650 rechargeable batteries standardization can be a large number of batch production. Normally charge treasure mobile power supply, mobile power supply can be attaches great importance to, is due to its role in real life is becoming more and more important, to our smart phone charging is particularly important. The mobile power supply to choose polymer lithium ion battery good or 18650 lithium batteries.
actually lithium polymer batteries is also belong to the batteries. Lithium batteries are divided into: liquid lithium ion batteries and polymer batteries. About two types of batteries, who is more safe and stable, it can't compare, key to see the manufacturers of the art.
polymer battery profile:
lithium polymer battery normally safe use soft lu: su composite film packaging format. Internal structure of semi solid polymer polymer. Use smooth discharge performance, high efficiency, small internal resistance. Has better safety coefficient, over-current, over-voltage protection device. The service life of the charge and discharge cycle frequency about five hundred times. But polymer batteries are often packed in foil to easy deformation, impact resistance, on the basis of different manufacturers to inferior overvoltage protection and so on.
polymer battery advantages:
the most mature and perfect, the most stable polymer battery, the vast majority of safe use in electronic equipment instrument. Safe use cycle is long, the normal safety when using cycle life can reach more than five hundred times, is a common rechargeable batteries more than twice. No explosion, burning; Non-toxic, low carbon environmental protection, through the RoHS certification brand; Be precise, all kinds of safety coefficient of one-time circulation frequency of more than five hundred times; Use ultra high temperature resistant performance is good, sixty-five - degree under the condition of charging and discharging efficiency was one thousand percent. To avoid rechargeable battery short-circuit fault condition, 18650 across the electrodes of lithium batteries are separated. So it appears again fault condition would have fall into extremes. Over the years, manufacturers in Japan 18650 rechargeable batteries on the production process of precipitated a lot of work experience, make the output of 18650 rechargeable batteries consistency check, the safety factor is done very high level
18650 lithium ion battery profile:
18650 lithium ion battery is lithium battery improved version of the product, after so many years of development, the lithium ion battery technology is already very mature, relatively large batch production has let its manufacturing cost is very cheap. So the lithium ion battery in price has more advantages than lithium polymer batteries. That is why most of today's devices such as laptop computers will be safe to use this batteries. Now the most common mobile power supply safe use steel 18650 battery shell, has high safety coefficient, production technology is already very mature, and the price is cheaper compared with polymer battery, occupying most of the lithium battery market share, more common in the laptop batteries.
lithium polymer battery ( Li- Polymer and polymer lithium battery) : it is also a kind of lithium ion batteries, but with liquid lithium batteries ( Li- ion) Compared with high energy density, miniaturization, ultra-thin, lightweight, and high security, and other obvious advantages, is a new type of battery. In shape, lithium polymer battery with ultra-thin characteristics, can match the needs of the various products, made into any shape and the capacity of the battery. The battery can achieve the minimum thickness can reach 0. 5mm。 The nominal voltage and Li - it As nominal voltage 3 ion. 7 v, no memory effect.
lithium polymer battery ( Li- Polymer, also known as polymer lithium battery) : a class of it is also a lithium ion battery, but with liquid lithium batteries ( Li- ion) Compared with high energy density, miniaturization, ultra-thin, lightweight, and a variety of obvious advantages such as high security is a kind of new type of battery. On the shape, characteristics around with lithium polymer batteries, can cooperate with all kinds of goods need, made into any shape and capacity of the battery. The battery can achieve the minimum thickness can reach 0. 5mm。 The nominal voltage and Li - it As nominal voltage 3 ion. 7 v, no memory effect.
move power supply selected polymer lithium ion battery or 18650 lithium batteries good
phone charging treasure better with lithium polymer batteries. Lithium polymer battery is lithium ion battery replacement goods, relative to the popular now lithium-ion batteries, has the advantages such as large capacity, small volume, safety. But the price is more expensive. So you can also start from your own choose yourself the right goods, so I am more recommend mobile power with polymer lithium battery pack.
In an age when custom lithium ion battery is increasingly important, the researchers believe manufacturers should pay close attention to their results.
To be the safest, most progressive domestic custom lithium ion battery, relentless in the pursuit of customer and employee excellence.
The development of custom battery pack manufacturers custom lithium ion battery products has massive potential for expansion.
Increasing consumer awareness and rising concern about improving custom battery pack manufacturers are driving the market of products.
