What is the harm to lithium batteries for overcharge and discharge?

source:other news release time:2022-10-10 Hits:0     Popular:Lithium-ion battery wholesale

  

  1. Overcoming and harm of lithium batteries

  1. Over charging means that the charging voltage of the battery exceeds the set voltage of the set when the lithium battery is overcharged. For example, the rated current of the rechargeable battery is ±. In other words, if the maximum operating voltage is higher than 9V, it is called over -charging. What is the harm of charging the rechargeable battery.

  2. During the over charging process, the battery voltage will rise rapidly with the expansion of polarization, which will cause irreversible changes in the structure of the positive active activity, which will cause the lithium battery electrolyte to dissolve, generate a large amount of steam, release a large amount of heat value , Greatly increase the temperature and air pressure of the battery, dissolve or close the external diaphragm, which causes the battery positive electrode and the positive electrode material to contact a short circuit failure, and there are hidden safety hazards such as explosion and fire.

  Second, the dangers of the lithium battery

  1. Excessive discharge refers to discharge after reaching the rated current during the charging discharge process. For example, if the rated charging and discharge work voltage of the ternary lithium battery is less than the voltage of the rated charging and discharge, it is over -discharged. What is the harm of excessive discharge to rechargeable batteries

  2. When the battery discharges the power of the external storage and the working voltage reaches a certain value, the discharge will cause the rechargeable battery to over -discharge. The excessive discharge of the battery will have a devastating effect on the battery, especially the power loss or repeated discharge under the large current will cause greater damage to the battery. Generally speaking, over -discharge will increase the gas pressure of the battery, destroy the cross of positive and negative active substances, dissolve the electrolytes of lithium batteries, accumulate negative electrode lithium, and increase resistance. Even after the battery is only partially maintained after charging, there will be a significant attenuation coefficient in the volume

  3. How to avoid excessive charging or over -discharge of daily use

  1. It is used in conjunction with lithium battery lithium battery protection board (BMS). The lithium battery protective board can charging and maintenance of the rechargeable battery. The smart version can also set the working voltage of the battery charging and discharge, which can better maintain the rechargeable battery

  2. The lithium battery charger used by supporting facilities does not use fast charging

  3. When the battery voltage reaches the working voltage set by the lithium battery protection board, the lithium battery protective board will turn off the power supply to maintain the rechargeable battery, but the lithium battery will decrease, the operating voltage will increase, and it will be slightly higher than the lithium battery protective board settings. Working voltage. This time will not be applicable. Continuous use will cause inevitable damage to recharging batteries.
