Revealing the effect of folk methods to extend the life of lithium batteries

Analyzing the effect of the Earth Workshop method to extend the service life of lithium batteries. Lifestyle revealed that when the beloved camera or mobile phone is often powered off when it is turned on, the battery standby time is getting shorter and shorter, and you don’t necessarily need a new battery. Recently, some small areas between the earthen houses are superior in creating various strange ways to buckle the cell phone battery. Two of the wide areas are where the battery is frozen in the refrigerator and rubbed by rubber. But are they really smart? The reporter specially invited experts from the Battery Laboratory of Guangzhou Weikai Testing Technology Institute to make judgments. Proof 1: Rubber conflict brass plate contact method Private secret recipe After removing the battery, wipe the contact (brass plate) on the battery with an eraser, and then put it back on the phone, the battery can be brought back to life, and it is the same as a new one. Experts say this only applies to some batteries. Regarding some lithium batteries, its working principle is a built-in protection panel. Lithium batteries generally have a built-in protection board to limit charging and discharging within a certain voltage range. When the voltage is abnormal (too high or too low), the protection board is triggered to cut off the power supply. The rubber conflict and the charging process may prompt the protection board to recover, so that the battery can be used normally again. In addition, it is not ruled out that sometimes there is dirt on the top of the terminal due to poor contact, and then after proper cleaning, it is normal to insist on conductive contact. Experts also reminded that the protection boards of some counterfeit batteries are not qualified and have not been reset, or the terminal material itself is not conductive and the touch is not good, or the quality of the battery is defective, how to use the eraser is a drop of water 2. 1. Pack the battery with newspaper and put it in a plastic bag. Put it in the refrigerator for three days. 2. Take it out after three days and leave it at room temperature for two days; 3. Charge the battery after two days and load it into the phone after charging, which is expected to save 80% to 90%. Experts say: This is unfounded. After a typical mobile phone lithium battery is used for one or two years, after hundreds of charging and discharging, the chemical activity of the root has been reduced, and effective charging and discharging cannot be performed. The above statement is actually a simple temperature cycle test. It is impossible to fully activate the internal chemical substances. The correct method is to have a professional recycling company decompose and extract useful active substances while preparing a new battery.
