3.7v 2200mah 18650 lithium battery

　　The difference between 3.7v 2200mah 18650 lithium battery and liquid lithium ion battery

　　There are two internal classifications of lithium-ion batteries: polymer lithium batteries and liquid lithium-ion batteries. Due to its high quality and wide application, the lithium battery in the field refers to the liquid lithium-ion battery, while the 3.7v 2200mah 18650 lithium battery is also called 3.7v 2200mah 18650 lithium battery.

　　If we compare the difference between lithium polymer lithium batteries and lithium batteries in theory and scope, then the only difference is the relationship between definition and dependent definition. Lithium batteries include lithium polymer lithium batteries. The difference between 3.7v 2200mah 18650 lithium battery and liquid lithium ion battery

　　1. The fundamental difference depends on the raw materials.

　　This is the total reason for their different performances. 3.7v 2200mah 18650 lithium battery refers to the use of polymer materials in at least one of three components: positive stage, negative stage or electrolyte solution. Polymer materials refer to high relative molecular mass, and the matching definition is small molecule water. Polymer materials have high toughness, high wear resistance and high elasticity. At present, polymer materials for polymer lithium batteries are mainly used for positive electrode and electrolyte solution. (1) In addition to the inorganic materials of lithium batteries, conductive polymers can also be used as battery cathode materials for polymer lithium batteries; (2) The electrolyte solution of polymer lithium batteries includes polymer electrolyte solution (solid or colloidal solution) and organic chemistry Electrolyte solution, while lithium batteries use electrolyte solution (liquid or colloidal solution)

　　2. Create differences.

　　Polymer lithium batteries can be arbitrarily thinned, arbitrarily expanded, and arbitrarily formed, because the lithium battery electrolyte can be solid but not liquid, just a colloidal solution, while lithium batteries use lithium battery electrolytes and require a solid casing as a secondary package. To hold the lithium battery electrolyte. Therefore, this also increases the weight of lithium batteries.

　　3. Security.

　　At present, most polymers are plastic soft-packaged rechargeable batteries, and plastic films are used as the casing. When organic lithium battery electrolyte is used internally, even if the liquid is very hot, it will not explode. Because the aluminum-plastic film 3.7v 2200mah 18650 lithium battery is in a solid or colloidal state, it will not leak and will only crack naturally. As everyone knows, there is nothing certain. If the instantaneous current is large enough and a short circuit occurs, the battery may catch fire or burst. Most security incidents on mobile phones and tablets are caused by this kind of situation.

　　4.Battery voltage.

　　Since polymer lithium batteries are made of polymer materials and can be made into double layers to achieve high voltage, and the allowable capacity of lithium batteries is 3.6V, in order to achieve high voltage in actual applications, several must be The batteries are connected in series to form an ideal high-voltage working platform.

　　If you use the above characteristics to compare lithium polymer batteries and lithium batteries, the result is undoubtedly. However, the use of lithium batteries still dominates the market, indicating that lithium batteries also have absolute advantages. Everyone will compare again.

　　5. Conductivity.

　　The positive ion conductivity of the solid electrolyte solution of polymer lithium batteries is low. Currently, some preservatives are added to turn it into a gel electrolyte solution to increase conductivity. This only increases the ion conductivity. Unlike lithium batteries, which maintain long-term values, they will not be affected by the quality of auxiliary materials.

　　6. Volume.

　　The capacity of polymer lithium batteries has not been reasonably improved. Compared with standard capacity lithium batteries, the capacity has been reduced to a certain extent.

　　7. The whole process of production and manufacturing.

　　The thinner the 3.7v 2200mah 18650 lithium battery, the better it can be manufactured, and the thicker the lithium battery, the better it can be manufactured, allowing lithium batteries to be expanded to more industries.

　　8. Price.

　　It is the primary condition that determines the market demand for both. The price of polymer batteries in the current market is generally higher than that of lithium batteries, which affects the market demand of both. The ratio of the former to the latter is 1:9.
