This is a special 2032/2025/2016 button battery case, and its positive case is coated with aluminum. The electrolyte (especially the electrolyte in LiPF6) will form an AlF3 film with the aluminum layer, so that the battery can withstand higher voltage polarization (up to 5.5 V) , the thickness of AlF3 layer is within several angstroms, which allows electrons to pass through and prevents free Al3+from entering the electrolyte.
Technical parameter
1. Battery case material: SS304/SS316 stainless steel;
2. A layer of aluminum is coated on the positive shell, which can also prevent the reaction between electrolyte and stainless steel shell under high voltage (>4.5V);
3. Negative electrode housing: made of 304 stainless steel, embedded with insulation ring;
4. As the positive battery shell is coated with a layer of aluminum, the charging voltage for the exploration of new lithium batteries can reach 5.5 V.
