How to share 'Lithium battery life extension'

What is the lifespan of lithium batteries? People are born and die from diseases, lithium batteries are processed and wasted, and lithium batteries cannot always be used again, and there will be a day when they become obsolete. People call this phenomenon the life of lithium batteries. People are born to determine their own limits, which cannot be changed. However, can science determine how long people’s daily habits extend within this limit; lithium batteries have a life limit from the moment they go offline. Similarly, the scientific use and maintenance of lithium batteries determines lithium The length of the battery extended within its life limit. This length is expressed by the charge and discharge cycle. The natural life of different types of lithium batteries (that is, the theoretical charge-discharge cycle) is inconsistent. An argument that people often hear is that the life of a lithium battery is 500. The principle time of a lithium battery refers to the life cycle. This is a full charge and discharge cycle. The industry test method is: deep discharge x charge u003d cycle life, The depth of discharge is 80% of the value, at least 625 charge and discharge times, 80%x625u003d500 (times). The depth of discharge refers to the percentage of the battery's discharge capacity to its rated capacity. The reason for using 80% depth of discharge is that the depth of discharge is closely related to the charging life. If the depth of discharge is too large, the battery life will be shortened. In our daily use of mobile phones, when the mobile phone reminds us that the battery is low, the mobile phone will start charging. So 500 cycles is the theoretical life of a lithium battery. Because people cannot fully pay attention to the problem of timely charging, therefore, the theoretical life of the lithium battery processing line and the manufacturer's test under the test conditions may not be reached by your battery. Your battery is: actual charge × × depth of discharge u003d actual Battery Life. Once the concept of cycle life is clarified, we can distinguish it from the charging time and the charging life of the supplier/consumer. The number of charging times marked on the electrical appliances or batteries sold is based on the 80% depth of discharge. Therefore, when someone hears this statement 500 times, they will think that the battery must be exhausted before charging the phone. This idea is unscientific in theory, but it is wrong in practice. This will cause premature damage to the battery structure due to overcharge or overdischarge, thereby shortening the service life of the lithium battery. Another common phenomenon is that mobile phone manufacturers often use the battery for a few years, a one-year warranty commitment. This commitment actually comes from the battery manufacturer. As mentioned at the beginning of the article, how many years can lithium batteries be used is closely related to The correct way to use lithium batteries, in addition to the provisions of the depth of discharge (ie. and prevention of overcharge, and some factors that may affect the service life of the lithium battery, such as the size of the current and voltage, the ambient temperature, and the maintenance of the idle power. It is pointed out that the natural life of lithium batteries is an upper limit in the final analysis. What we usually call the method of extending the life of lithium batteries actually refers to the correct use and maintenance of lithium batteries, which can release more energy.
