Aluminum electrolysis basically consists of positive electrode foil + oxide film (cannot exist independently of the positive electrode foil) + electrolytic paper (impregnated with electrolyte) + negative electrode foil + shell + rubber plug + lead + sleeve
The first step: the corrosion of aluminum foil: increase the area by tens to hundreds of times, uneven
Step 2: Oxide film formation process: form an oxide film with unidirectional conductivity
The third step: cutting of aluminum foil
The fourth step: riveting the lead
Step 5: Winding of electrolytic paper
Step 6: Impregnation of electrolyte
Step 7: Assembly: Aluminum shell and rubber stopper
The eighth step: crimping: adding casing
Step 9: Aging: under rated voltage and rated temperature
