  The difference between polymer lithium battery and lithium ion battery 18650 price

  The difference between polymer lithium battery and lithium ion battery 18650 price

  Compared with lithium-ion batteries, polymer lithium batteries have the following characteristics:

  1. There is no liquid lithium battery electrolyte in rechargeable batteries, and solid-state batteries are used.

  2. Thin rechargeable batteries can be made: in terms of volume, the thickness can be as thin as 100%.

  3. Design of rechargeable batteries

  4. The rechargeable battery can be bent and deformed: the polymer rechargeable battery can be bent up and down 900 degrees.

  5. Can be made into single-bead high-voltage: liquid electrolyte rechargeable batteries can only be obtained by connecting in series to obtain high-voltage, polymer material rechargeable batteries.

  6. Since it has no liquid, a double layer can be made within one piece to create a high voltage.

  7. The capacity will be twice that of a lithium battery of the same size.

  2. Polymer lithium battery life

  Lithium battery life is related to battery charge cycle time frequency, but battery charge frequency is not immediately related.

  For example, lithium batteries understand that, for example, a lithium-ion battery only uses half of its charge on the first day and then is fully charged. If it is still the same the next day, that is, half of the charge, a total of two batteries are charged, which is only the time of one battery charging cycle, not two. Therefore, it may take several rounds to recharge the battery. Each time the battery charges cycle time, the charge decreases a little. However, this reduction is small, and after a few cycles of a high-quality rechargeable battery, 80% of the initial consumption will still be in place, which is why many lithium-ion battery-powered products are still in use after two or three years. Natural lithium-ion batteries must eventually be replaced.

  The service life of lithium battery is 300500 battery cycle times. Assuming that the amount of electricity used for full charge and discharge is q, a lithium-ion battery can present or fill 300q-500q of power items during its service life, regardless of the reduction in power consumed after each battery charge cycle. So we know that if we fill in 1/2 each time, we can fill it 600-1000 times, and if we fill it 1/3 each time, we can fill it 900-1500 times. In this case, if the battery is charged, the frequency is undefined. In short, filling 300q500q power is stable in any way. Therefore, we can also understand that the life of lithium battery is related to the total charging capacity of the battery and has nothing to do with the number of charging times. There is little difference in the impact of deep discharge, deep charge and shallow discharge on the life of lithium batteries.

  If the lithium-ion battery is used in a natural environment above 35 degrees Celsius, its operating temperature may continue to reduce the power used by the rechargeable battery, that is, the battery-powered system will not last as long as in the past. If the battery is charged at that temperature, the damage to the battery will be greater. Even storing and discharging rechargeable batteries in warm natural environments will inevitably cause relative damage to battery quality. Therefore, maintaining proper operating temperature is a good way to increase the life of lithium-ion batteries.

  If lithium batteries are used in ultra-low temperature environments, that is, below 4c, you will also find that the use of rechargeable batteries is reduced. Some original lithium batteries do not even charge in the ultra-low temperature environments of mobile phones. But don't worry too much, this is just a temporary situation, different from using high temperature natural conditions. Once the temperature rises, the rechargeable battery's molecular structure heats up and returns to its previous consumption.

  In order to fully exploit the efficiency of lithium-ion batteries, the electronic devices in lithium-ion batteries must be in a fluid state regularly. If the lithium battery is not used frequently, please remember to charge the lithium battery every month and perform battery calibration, that is, depth calibration.
