18650 lithium 3.7 battery

　　The advantages of 18650 lithium 3.7 battery are as follows:

　　1. The working standard voltage of 18650 lithium 3.7 battery is 3, 6v3, 8v, which is much higher than nickel metal hydride and nickel cadmium batteries.

　　2. The volume density of 18650 lithium 3.7 battery is large, and the relative volume density is 1, 5-2, 5 times or higher than that of nickel metal hydride rechargeable batteries or nickel cadmium batteries.

　　3. Lithium-ion batteries of 18650 lithium 3.7 battery have a short lifespan and small volume damage after long-term storage.

　　4. The polymer lithium battery has a long life and can be used more than 500 times.

　　5. 18650 lithium 3.7 battery have no memory effect, and there is no need to clear the remaining power before charging, making it easy to use.

　　6. Good safety factor

　　The structure of polymer lithium battery is made of aluminum-plastic soft packaging, which is different from the plastic shell of liquid lithium ion.

　　7. Small, can become thinner

　　Lithium 18650 lithium 3.7 battery are thin, rechargeable batteries that can be assembled into overdrafts. Generally, liquid lithium batteries first choose a custom casing, and then insert the cathode material. The thin thickness is guaranteed to be below 3.6 mm. There are technical shortcomings. Polymer chips will not have this problem. The thin thickness can be guaranteed to be below 3 mm, according to the requirements of the mobile phone.

　　8.Lightweight

　　Lithium 18650 lithium 3.7 battery are used as maintenance packaging boxes for metal-free polymer electrolyte rechargeable batteries. The net weight of 18650 lithium 3.7 battery is 40% lighter than aluminum-cased lithium batteries and 20% lighter than aluminum-cased rechargeable batteries.

　　9.Scale

　　18650 lithium 3.7 battery are 1015% higher than aluminum shell batteries of the same specifications and 510% higher than aluminum shell batteries. They have become the first choice for color screen mobile phones and mobile color mobile phones. Now most polymers on display screens and mobile color mobile phones in the new market choose.

　　10. Small internal resistance

　　The internal resistance of 18650 lithium 3.7 battery is smaller than that of ordinary liquid lithium batteries. At present, the internal resistance of domestic polymer cores can even be guaranteed to be less than 35m, which greatly reduces the self-consumption of rechargeable batteries, increases mobile phone navigation, and reaches the level of international docking. This kind of polymer lithium battery suitable for large charge and discharge current is also an ideal choice for remote control mode, becoming the most promising rechargeable battery alternative.

　　11. The shape can be customized

　　Manufacturers do not need to be limited to the appearance design of the specification and can be economically developed to the appropriate size. 18650 lithium 3.7 battery can be improved or reduced according to customer requirements. The developed lithium battery models are standardized, low-priced, and have short mold time. Some can even be based on samples on mobile phones to flexibly utilize the room space of the battery casing and improve battery power. .

　　12. Good charge and discharge characteristics

　　18650 lithium 3.7 battery use colloidal electrolyte solutions. Compared with liquid electrolyte solutions, colloidal electrolytes have stable charge and discharge characteristics and a higher charge and discharge service platform.

　　13. Design scheme of lithium battery protection board

　　Due to the presence of polymer raw materials, polymer lithium battery cores will not catch fire or explode, and lithium batteries have sufficient safety factors. Therefore, the maintenance route design of 18650 lithium 3.7 battery can take into account the loss of PTC and safety tubes, thereby saving battery costs. .
