As mobile phone functions become more and more powerful, power consumption is also faster and faster. Many people charge their mobile phones twice a day or plug them in all the time, which is very harmful to the battery. In order to solve these problems, Japanese parts giant A new material battery developed by TDK may hold the key.
This is a new type of solid-state battery without any trace of electrolyte. It is different from the currently popularButton batteryCompared with the new battery, the safety performance is higher. The size of the TDK battery is equivalent to an ordinary button, but it is "small but has five internal organs" and stores a large amount of energy. It is a solid-state battery, so if you have one on your mobile phone application, which can provide more power to the phone.
A typical mobile phone battery begins to decline after being fully charged and discharged 500 times. Currently, this problem can only be solved by increasing the charging speed of the mobile phone, so many mobile phones on the market have fast charging functions. But the problem of the battery itself has not yet Solution. The performance of TDK's solid-state battery has been greatly improved and can be charged 1,500 times. This means that users can use mobile phones with this battery for more than 3 years without significant performance degradation.
Many industries, including 3 Star and LG, are racing to develop such batteries. In addition, future mobile phone batteries may be as big as buttons, giving the phone more room to operate.
The mobile phone battery itself has a capacity, or the maximum capacity. This capacity will gradually decrease with the use of the battery, which can be called the actual capacity.
The battery control circuit of the mobile phone also records a battery capacity. This capacity is the battery capacity displayed on the mobile phone, which can be called the recorded capacity.
Usually, the actual capacity and recorded capacity of a new mobile phone are almost the same, so the power displayed on the phone at this time is almost the same as the actual remaining power in the battery. That is, when the mobile phone shows that there is still 50% remaining, then there is indeed still. 50% remains. However, as the mobile phone is used, the battery ages and the actual capacity is reduced, while the recording capacity is still the same. For example, at this time, the mobile phone thinks that there is still 50% of power in the battery, but in fact there may be only 50% left in the battery. 30 percent.
Battery calibration is to fully charge the mobile phone battery once, and then slowly and completely discharge it, so that the mobile phone circuit updates the "recorded capacity" and makes it close to the actual capacity of the battery (calibration cannot completely make the two consistent).
Therefore, battery calibration will not increase the battery life of mobile phone batteries, and since the calibration process involves deep discharge, which is very bad for lithium batteries, the actual capacity after calibration is likely to be further reduced.
Of course, there is a special case where you switch to a counterfeit battery with a larger capacity than the original battery. In this case, since the recorded capacity of the battery is lower than the actual capacity, correction can be made to charge the battery more fully.
