Smart phone configuration and higher, consuming more and more fierce, some mobile phone battery is not replaced, such as the iPhone, encountered cases only by moving the power of electricity (also known as Po or external battery, charging, etc) in an emergency, created the current mobile power market sale flyer. Many consumers choose to move when the attention is only put on the appearance, size, and price, it is often difficult to understand the situation of mobile power, and today we introduce mobile power batteries.
The internal structure of mobile power
First, simple to understand the power of the Constitution:
1, shell, primarily product packaging, as well as pleasing and protection functions, it is common for plastic and metal, some of the better products are often plastic is made from fireproof materials;
2, batteries, which is our common battery, is the power of mobile power storage;
3, Circuit boards, mainly used for control of voltage, current, input and output control, as well as other various functions.
18,650-core, the other is polymer batteries, which ruled two batteries the lithium battery industry in the vast share of the market.
18650 batteries
18,650 lithium ion battery
18,650 is line within called, refers to battery diameter for 18mm, length for 65mm, cylindrical size of battery, like international manufacturers Sanyo, Panasonic, Samsung, and Sony, are has this block business, and domestic also has many manufacturers in production and sales 18,650 electric core, market see of mobile power, most used 18,650 electric core, and to spell cost, basic are with of is domestic produced of products, very rare used imports manufacturers of 18,650 electric core.
Adopt 18650 batteries of power bank
Capacity of 18650, generally of common is 2200mAh, 2400mAh and 2600mAh three kinds of specifications, according to introducing is now the biggest single can be done has 3400mAh capacity. The basic is 18650 batteries of power bank, several kinds of specifications in parallel implementation. 186,501 steel cylindrical shells using packaging, the internal lithium-ion-liquid. Because already the industry standard specifications, 18,650 only for cylindrical, if you purchased mobile power see big, big style, basic 18,650 batteries could be determined.
18650 batteries of quality accident
When it comes to security, battery is the cube, and in extreme cases can result in serious quality accident. 18650 batteries as used steel packaging, the most serious cases of explosion occurred, like the familiar laptop battery we also use 18650 batteries, Sony Corporation appeared in early years volume because of serious quality accidents in the battery recall.
Currently on the market many spell sheep mobile power in order to cut costs, using inferior 18650 batteries, called impossible. Mobile power products is carried by the user, if the quality does not cross the border, it’s like a time bomb walking around, which is why we purchase AMS product brand and price, do not blindly pursue the cheapest.
Polymer batteries
Lithium polymer electric core
Lithium polymer electric core, raw material mining lithium cobalt oxide, lithium manganate, lithium and tri-mix of package, mainly user aluminum composite film, lithium in the middle of substances to the paste, so can customize the shape, ultra-thin batteries such as the 0.25mm, so using polymer battery mobile power, can also be designed to be more flexible in appearance. Ultra-thin mobile power, as well as on the market such as iPhone4 phones back clip, is the use of polymer batteries.
Using polymer ultra-thin mobile power supply
Using polymer thin mobile power flexible polymer battery package does not have a fixed size like 18650, directly depends on the size of its capacity, while the raw materials used are also related.
Cell phone battery quality accident
Polymer batteries is the greatest security leakage, short circuit, leading to rising, most adverse conditions can produce burning, compared with 18650, polymer batteries relatively better. But burns also pose a security risk, it is recommended that users that use mobile power, try not to move the power placed in a combustible environment.
Current high-end mobile power the vast majority of polymer batteries are used, such as Wing Road, MiLi brand products. Stand on the security perspective, it is recommended that users condition polymer batteries as much as possible when purchasing mobile power products, especially high capacity mobile power, like 8000mAh, if it is composed of multiple 18650 batteries are definitely not blow up is to produce a flame.
