About the common problems of lithium-ion batteries

Source: 2020 - 04 - 15 18:44 hits: times of the common problems of lithium-ion batteries: why do you give a new battery? New battery charge several times before the main function is to activate the battery. Lithium battery is in after a period of time after the placement of enter a dormant state, capacity is lower than normal at this time, use time is shortened. Lithium battery is easy to be activated, however, as long as three to five times the normal charge and discharge cycle can be activated, and normal capacity. ( 2) A few times before charging need 12 hours? Due to the characteristics of lithium battery itself, it has almost no memory effect. Therefore, users of the new lithium battery in the process of activation, and is not a kind of special methods and equipment. For li-ion batteries' activate 'problem, there are a lot of argument is: charging time must be more than 12 hours, repeated three times to activate the battery. 'the first three time charge 12 hours' is the obvious continuity of nickel battery, such as nickel cadmium and nickel metal hydride. So this is a kind of misinformation. ( 3) Charging time is too long can damage the lithium battery? Official technical literature stressed that can cause serious damage to the lithium ion battery charging, especially liquid lithium ion battery. So, had better be in accordance with the standard time and standard charging methods, especially don't charging more than 12 hours long. When a full charge, lithium battery or charger will automatically stop, this means that if your lithium battery fully charged, the charger will be left blank. No one can guarantee that never change the characteristics of the battery charge and discharge protection circuit is quite safe quality, so your battery for a long time in the future will be in danger. This is another reason we against charging for a long time. In addition, if the charging in on some machines, after a period of time is still not take out the charger, the system will not stop charging, also will begin to charge and discharge cycle. Manufacturers may have their own goals, but this is obviously not conducive to battery life. At the same time, the charging takes a long time for a long time, generally charge at night. China power grid, for example, in many places at night voltage is higher, volatile. But lithium ion battery is very fragile, and compared with nickel battery, they to charge and discharge fluctuations of elasticity is much smaller, which increases the risk.
