How many years are lithium batteries?lifepo4 48v 100ah lithium ion battery

　　With the advent of lithium batteries, its service life has always been a fan. Many friends are not clear about the service life of lithium batteries. This article takes the lithium battery of mobile phones as an example to introduce this.

　　When it comes to the life of lithium batteries, we must talk about its materials, structure and application technology. Due to different materials and different structures, different application technology will affect the life of lithium batteries. According to the relevant test data, the theoretical life of lithium batteries is about 300 to 500 times.

　　Some people may ask, why is the battery life of the battery be "second"? Take the mobile phone, "the number of charging" is not to say "the number of charging", but the "full power number", that is, from the 5%battery to 100%of the battery, it is a full power battery, and from the from The 100%battery is fully charged, and the 5%battery is full of 5%battery, which is considered a full power.

　　Each product must be tested rigorous, and the service life of lithium batteries is also the key to detection. Many manufacturers will conduct a series of tests when they release a new lithium battery. Take test data, assuming that the service life of the battery from 300 to 500 times, if it accurately calculates it to 400 times, the actual battery life will definitely be than 400 (full charge, discharge situation) less. It's much more. Manufacturers can choose the material, design structure and use technology of the battery, but the use environment of the battery, the external environment will change, and the frequency of the user's (mobile phone) device. These factors will produce the service life of the battery's usage life. Influence.

　　Take the lithium battery of the mobile phone, in the previous article, we once said that the theoretical charging of lithium batteries is about 300-500 times. If the user is charged every two days, we need to perform 180 times a year in one year. The left and right charging, but most of the mobile phone batteries have been used for more than three years. Why hasn't it been eliminated?

　　You know, the service life of the battery is limited, but its service life is gradually shortening. It is not eliminated at the beginning, but gradually gradually gradually gradually gradually eliminated. For shortening, many users say that after a period of use, the battery life of the battery will become worse and worse, but most of the time, most mobile phones will have a decline in battery life, but even in the theoretical service life, in fact, in fact, in fact, in fact, in fact, in fact, in fact, in fact, in fact, in fact, in fact, in fact, in fact, in fact, in fact It can still be used, but the proportion of performance decline will be more than 20%.
