lithium battery 18650 3.7v

　　Advantages of polymer lithium battery 18650 3.7v

　　1. The working standard voltage of a single rechargeable battery is much higher than that of nickel-metal hydride rechargeable batteries and nickel-cadmium rechargeable batteries.

　　2. The volume density is high, and the relative volume density is twice or more higher than that of nickel metal hydride rechargeable batteries or nickel cadmium batteries.

　　3. Lithium batteries have a short life span, long storage time, and small volume loss.

　　4. Long life, the service life of its circulation system can reach more than 500 times under normal use.

　　5. There is no memory. There is no need to drain the remaining power before charging the battery, which is convenient to use.

　　6. It has excellent safety factor.

　　The structure of the polymer lithium battery adopts aluminum-plastic soft packaging, which is different from the plastic shell of the liquid lithium battery. Once a safety risk occurs, the liquid lithium battery is very easy to explode, and the maximum number of liquid lithium batteries will only cause an air bulge.

　　7. The thickness is not large and can be made thinner.

　　Thin, rechargeable battery fits on credit card. Generally, the lithium liquid adopts the method of customizing the casing first, and then inserting the positive electrode material of the battery. The thickness ensures the following technical shortcomings. Polymer batteries do not have this problem. The thickness can be guaranteed to be less than millimeters, which is suitable for current mobile phones. required direction.

　　8. The net weight is very light.

　　Rechargeable batteries that use polymer lithium battery electrolytes do not use plastic shells as external protection. Compared with aluminum-cased lithium batteries of the same volume and specifications, polymer lithium batteries are 40% lighter and 20% lighter than aluminum-cased rechargeable batteries.

　　9. Large volume;

　　Compared with aluminum-shell batteries of the same specifications, polymer lithium batteries have a capacity that is 10~15% higher and 5-10% higher than aluminum-shell batteries. They have become the first choice for color-screen mobile phones and MMS mobile phones. In the current market Polymer batteries are also commonly used in displays and MMS phones released on the shelves.

　　10. Small internal resistance.

　　The internal resistance of polymer cores is smaller than that of ordinary liquid lithium batteries. At present, the internal resistance of domestic polymer cores reaches less than 35 meters, which greatly reduces the self-consumption of batteries, increases the battery life of mobile phones, and completely Able to connect with the international community. Polymer lithium batteries are suitable for high-current charging and discharging. They are an ideal choice for remote operation and are the most likely product to replace nickel-metal hydride rechargeable batteries.

　　11. The shape can be customized according to customer requirements.

　　Manufacturers are not limited to standardizing appearance designs and can economically produce appropriate specifications. The thickness of the lithium battery can be increased or reduced according to customer satisfaction, and new lithium batteries can be developed and designed with high quality and low price, and short mold release cycle. Some can even be customized according to the shape of the mobile phone to fully utilize the space of the battery casing. Boost battery power.
