Which polymer lithium-ion battery or lithium-ion battery is better?

Which is better, polymer lithium battery or lithium battery? With the booming commodity market and the emergence of various power sources, power can be said to emerge in endlessly in the pursuit of consumers. However, whether the safety of the battery can be recognized and accepted by people depends on the usage. Polymer lithium batteries and lithium batteries are commonly used power sources. The question now is: which battery is the best? Polymer batteries are polymer lithium batteries, lithium batteries, and polymer lithium batteries have more advantages than lithium batteries. The following summarizes the advantages of polymer lithium batteries: (1) Large capacity density, its capacity density is 1.5~2.5 times or even higher than nickel hydride battery or nickel cadmium battery; (2) Small self-discharge, long storage time, small capacity loss; (3) Long service life, normal use cycle The service life can reach more than 500 times; (4) No memory effect, no need to empty the remaining power before charging, easy to use; (5) Good safety performance, because the polymer physical battery adopts aluminum-plastic soft packaging in structure, which is different from the liquid of metal shell Once there is a safety hazard, the liquid battery is easy to explode, while the polymer battery will only swell. However, the disadvantages are as follows: 1. The cost of the battery is high, and it is difficult to purify the electrolyte. 2. To protect and control the circuit, overcharge or overdischarge will destroy the reversibility of the chemical substances in the battery, which will seriously affect the service life of the battery. Lithium batteries have a high voltage platform; compared with batteries, lithium batteries have a higher energy density. The storage energy density is high; lithium batteries are lighter than lead-acid batteries. The service life is longer, and the service life can reach more than 6 years; the lithium battery has strong adaptability to high temperature and low temperature. The disadvantages of lithium batteries are: poor safety and high risk of explosion; lithium batteries made of lithium cobalt oxide cannot be discharged under high currents, and their safety is poor. All lithium batteries must protect the circuit to prevent the battery from being overcharged and over-discharged. All in all, if it is a comparison of the safety of lithium iron phosphate batteries> polymer lithium batteries> lithium batteries, but there are advantages and disadvantages in terms of cost and various practical applications, so mastering the above two batteries is conducive to more scientific use battery.
