If you confirm that the battery cell has been punctured, it is best not to use it! If the liquid leaks, it will corrode the circuit board of the mobile phone and cause greater losses.
What my friend from the second floor said is wrong. Cell phone batteries are single-cell lithium-ion batteries, not connected in series. There are also some cell phone batteries whose cells are wrapped in aluminum foil instead of stainless steel, which can be easily punctured.
Yes.
1. In the production process of lithium battery aluminum foil, some waste residues will be produced. These residues mainly include scrap aluminum, scrap aluminum foil, waste liquid, etc.
2. Aluminum shavings are mainly generated during cutting, grinding, polishing and other processing processes.t.
3. Waste aluminum foil is mainly defective products produced during the production process or broken aluminum foil cut during the production process.
4. Liquid waste refers to chemicals, solvents, etc. used in the production process.
