Would the questioner want to ask: "Is it possible to have 0.02 volts between the lithium battery and the case?" Can. The slight difference in voltage between the battery and the case is caused by the chemical reaction and flow of electrons inside the battery. A voltage of 0.02 volts between the lithium battery and the case is acceptable.
Use a clean eraser or other cleaning tools to gently wipe the metal contacts of the lithium battery and the metal contacts of the mobile phone.
1. Use a clean eraser or other cleaning tools to gently wipe the metal contacts of the lithium battery and the metal contacts of the mobile phone, which will improve the charging status and power durability. .
2. Fully discharge the almost discarded lithium battery, then recharge it to activate the battery.The specific method is to deeply discharge the mobile phone, which is to achieve deeper charging by exhausting the internal energy.
Ternary lithium polymer battery refers to a lithium battery whose cathode material uses nickel cobalt lithium manganate ternary cathode material. It is a precursor product of a ternary composite cathode material, composed of nickel salt, cobalt salt and manganese. salt. As raw materials, the proportion of nickel, cobalt and manganese can be adjusted according to actual needs.
