Source: 2020 - 04 - 04 31 hits: what is the life of lithium-ion batteries? People birth and death of the disease, production and waste lithium batteries, lithium batteries always cannot be used again, and have the scrap one day, people say this phenomenon for lithium battery life. Born determines your limits, this is can't change. However, science can determine People's Daily habits within the limit of extended length; Lithium battery from the moment of offline, also have a life of the limit, also, the scientific use of lithium battery and maintenance decision within the limit of the lithium battery in the life of extended length. This expressed in charge and discharge cycle length. The natural life of the different types of lithium ion battery ( The theory of charge and discharge cycle) It is not consistent. People often hear an argument is, '500' is the life of lithium-ion batteries, lithium batteries of the principle of 'time' refers to the cycle of life, this is a full charge and discharge cycle, industry test method is: depth charge discharge x = cycle life, the value of the discharge depth is 80%, the charge and discharge at least 625 times, 80% of 625 = 500 x ( Times) 。 Refers to the discharge capacity of the battery discharge depth as a percentage of nominal capacity. With 80% discharge depth is closely related to the depth of discharge and recharge is the cause of life. If the discharge depth is too big, can shorten the battery life. In the process of using mobile phones in our daily, when the mobile phone tips we electricity shortage, recharge the phone is about to start. So a 500 - cycle is the theory of the lithium battery life. Because people cannot fully attention to the problem of charging in time, therefore, lithium battery production line, the manufacturers under the condition of test test the theory of life, your battery can not achieve, your battery is: the actual charging & times; × The depth of discharge = actual battery life. Once a clear definition of the concept of the cycle of life, we can associate it with suppliers/customers say 'charging time' and 'charge fixed number of year. Sold by electrical or battery on charging times the depth of discharge of 80% as a benchmark. Therefore, when people hear the phrase, '500', they may think before charge their phone, the battery must be exhausted. The idea is not scientific in theory and in practice is wrong. This will make the battery structure due to overcharge or overdischarge and premature damage, so as to shorten the service life of lithium-ion batteries. Another common phenomenon is that the mobile phone manufacturers often make the battery for several years, one year warranty commitment, the commitment is actually comes from the battery manufacturers, as the beginning, how many years can use lithium ion battery, and is closely related to the right way to use lithium battery, in addition to the provisions of the depth of discharge ( Namely. And prevent overcharge, and some may affect the service life of the lithium battery, such as the size of the current and voltage, ambient temperature, idle power to maintain and so on. It is necessary to point out that the natural life of lithium-ion batteries is ultimately a limit, we usually say 'lithium battery life extension method, actually refers to the correct use and maintenance of lithium batteries, lithium batteries can release more energy.
