How long will the lithium-ion battery in 1865 last?

At present, the total cycle life of 3.7 V 18650 lithium-ion battery can reach 500-1000 times,Battery recycling line 3.2 V 18650 lithium-ion battery's total cycle life can reach 2000 times. Of course, the premise is that the qualified battery by the regular manufacturers, if the battery is defective or counterfeit, life will be very short. The 18650 lithium-ion battery has a lifetime of only two to three years.

Lithium battery companies generally we can charge 300-500 times. lithium battery welding machine It is best to analyze partial discharge of lithium battery technology, rather than a completely different discharge, and to try to avoid students often complete discharge. Once the battery is off the production line, the clock starts running. Whether you need to use it or not, lithium batteries have a network life of only two to three years.

The life of a 18650 lithium-ion battery is typically 300 to 500 charge cycles.mounting machine Assuming a full discharge to provide Q, lithium can provide or supplement its life of 300Q-500Q, either after a reduction in each charging cycle. So we know that if you charge 1/2, you can charge 600-1,000 times; if you charge 1/3, you can charge 900-1,500 times. For example, if the charge is random, then the degree is variable.

It is often said that the life of a lithium-ion battery is“500 times”, and“Multiple” in the theoretical meaning of lithium-ion battery cycle life, that is, a complete charge and discharge cycle. The industrial test method is as follows: discharge depth x charge number = cycle life, numerical discharge depth is 80% , at least 625 times of charge and discharge, that is 80% x 625 = 500(.

In short, no matter how charged, the total power supply into the 300Q ~ 500Q power supply is constant. So here's another way to think about it: lithium-ion battery life depends on how much power the battery has, not how many times it has to be recharged. The effect of deep and shallow charges on the lifetime of lithium is similar.

How to double the life of 18650 lithium battery?

First, lithium-ion batteries fear heat and cold, do not use in extreme environments

Many people like to put their lithium-ion electric cars in the sun in summer, or park them in the yard or on the street in winter, which is not good for their battery life, and the migration rate of lithium ions through electrolytes and electrodes is closely related to temperature. Theoretically, the temperature from-20 C to 55°C can be used normally.

When the temperature is between 5 ° C and 35 ° C, there is no harm to lithium batteries. Northern users in winter try to take lithium batteries home storage, do not put outdoors. Southern users should avoid sun exposure in summer.

Lithium batteries for electric cars are too expensive. Can lead-acid batteries be used instead of lithium batteries for electric vehicles?

What kind of low-temperature lithium battery is better?
