　　Key advantages and disadvantages of polymer cr2032 button battery

　　Advantage:

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

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

　　3. The life of lithium battery is short. If it is left for too long, its volume loss will also be small.

　　4. Long life, its normal use cycle can exceed 500 times.

　　5. There is no memory, so you don’t need to drain the remaining power before charging the battery, which is convenient to use.

　　6. Excellent safety factor.

　　The structure of the polymer lithium-ion 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 liquid lithium battery will only cause an air bulge at most.

　　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 should ensure the following technical shortcomings. Polymer batteries will not have this problem. The thickness can be guaranteed to be less than millimeters, which is suitable for current mobile phones. required direction.

　　8. Light weight

　　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 space.

　　Compared with aluminum-shell batteries of the same specification, 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 mostly 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. Can be customized.

　　Manufacturers do not need to be limited to standard 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 demoulding 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.

　　12. Excellent charge and discharge characteristics.

　　Compared with liquid electrolyte solutions, polymer lithium batteries use colloidal electrolyte solutions, which have stable charging and discharging characteristics and a higher charging and discharging platform.

　　13. The design of the lithium battery protection board is very simple.

　　When polymer materials are used, lithium batteries are unlikely to catch fire or explode, and the lithium batteries themselves are sufficiently safe. Therefore, the maintenance route design of polymer lithium batteries can consider eliminating PTCs and circuit breakers, thereby saving battery costs. fee.

　　Disadvantages:

　　1. The cost of rechargeable batteries increases, and the lithium battery electrolyte system cannot be purified.

　　2. To maintain line operation, overcharging or overdischarging will destroy the consistency of the compounds in the battery and seriously affect the battery cycle times.
