18650 battery rechargeable

　　Advantages of 18650 battery rechargeable

　　1. Excellent safety factor.

　　The structure of the polymer lithium battery adopts 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, while the polymer lithium battery will only cause an air bulge at most.

　　2. The thickness is not very large and can be made thinner.

　　Generally, liquid lithium batteries use a custom-made cover first, and then insert the positive and negative stages. There are technical shortcomings in achieving the thickness requirements. However, polymer batteries do not have this problem, and the thickness can be as thin as millimeters. The following are in line with the current requirements for mobile phones.

　　3. Light weight.

　　Compared with standard polymer lithium batteries of the same volume, aluminum-cased lithium batteries are 40% lighter and 20% lighter.

　　Fourth, it has large capacity.

　　Polymer lithium batteries have 10-15% higher power than aluminum-shell batteries of the same specifications and 5-10% higher power than aluminum-shell rechargeable batteries. They have become the first choice for color-screen mobile phones and MMS mobile phones. Displays currently on the market have released Flocculant lithium batteries are also often used in screen and MMS mobile phones.

　　5. Small internal resistance.

　　The internal resistance of polymer lithium batteries is smaller than that of ordinary liquid lithium batteries. At present, the internal resistance of domestic polymer cores can even reach less than 35 meters, which greatly reduces the self-consumption of batteries and increases the use of mobile phones. The battery life is fully capable of reaching international standards. This polymer lithium battery is suitable for high-current charging and discharging. It is an ideal choice for remote operation and has become the best alternative to nickel-metal hydride rechargeable batteries.

　　6. Can be customized.

　　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. , to increase battery power.

　　7. Excellent charge and discharge characteristics.

　　Compared with liquid electrolyte solutions, polymer lithium batteries use colloidal electrolyte solutions to give them smooth charge and discharge characteristics and a higher charge and discharge platform.
