li ion 18650 battery pack

　　Which one is stronger, polymer lithium battery or lithium-ion battery?

　　Polymer lithium batteries are getting stronger, and li ion 18650 battery pack are facing the risk of being eliminated. The negative stage of li ion 18650 battery pack is metallic lithium. The first is a lithium manganese dioxide rechargeable battery, which reacts in the redox reaction of Li+MnO2=LiMnO2. The main use of approximately lithium metal battery operating voltage is in the battery cathode material. At present, the main ones are still used in button batteries, and the others have been replaced by lithium polymer batteries or lithium batteries. If lithium is a more reactive metal than sodium, then the battery is very easy to lose, that is, it is very easy to produce redox reactions. Acetate is obvious, and even radon gas in water can be replaced. Lithium batteries basically react with the gas. In the past, lithium batteries were commonly used to make fire in the countryside, which meant smashing the rechargeable battery. The lithium inside reacted with the gas and released a huge amount of gas. The amount of heat generated shows how dangerous lithium batteries are.

　　Unlike lithium batteries without metallic lithium, lithium batteries are rechargeable batteries whose operation mainly depends on the movement of li ion 18650 battery pack between positive and negative stages. During the process of charging and discharging, Li+ is inserted or deintercalated back and forth between the two levels: when charging the battery, Li+ is deintercalated from the positive level to the negative level, and after passing through the electrolyte solution, the negative level is in a lithium-rich state; charging and discharging When , Li+ is inserted in reverse. The polymer material rechargeable battery is actually a lithium battery, and its basic principle is the same as that of lithium batteries. Unlike lithium batteries, the lithium battery electrolyte inside is replaced by electrolyte solution, which is safer and has a smaller volume.
