What are the manufacturing methods of aluminum batteries?

1. Preparation of original materials

　　 First of all, we must prepare a series of manufacturing materials, such as a 100 ml beaker, an aluminum can, and a pack of sandpaper and cotton cloth, scissors and charcoal.

　　 I want to specifically emphasize charcoal, because there are many types of charcoal, and the charcoal we need here is a special low-resistance charcoal that we need to make extra. The method of making low-resistance charcoal is to burn the wood in an environment with sufficient oxygen, and then carbonize the wood in an oxygen-deficient environment. When the charcoal is just carbonized, enough oxygen is given to make the charcoal regenerate. Incineration, at this time, the temperature of charcoal incineration is very high, and then we can observe that the charcoal surface will undergo graphitization, which is the low-resistance charcoal we need.

　　2, the specific manufacturing process

　　 The next step is the specific manufacturing process. First of all, we have to cut the cans. In order to avoid scratching the cans during the cutting process, it is necessary to wear gloves during the disassembly process. Then we put the cut out piece of aluminum into a beaker to fit, remember to save this section of the aluminum sheet as the negative electrode of the battery, and trim the corresponding sharp part, and then we have sand and stone to continuously polish the aluminum Remove the insulating material on the aluminum sheet, and then ask you to put the sheet into the beaker prepared in advance, put the aluminum sheet against the inner wall of the beaker, and then stuff the cotton cloth. Let's put some charcoal into the beaker, and then press the solid wood charcoal with a stick. We insert the graphite electrode slightly in the center, sprinkle charcoal evenly around the electrode, and then poke the charcoal around the graphite electrode with a grinding rod. The tighter the poke, the better the function of the battery.

　　3, battery case manufacturing

　　 Then we pour a small amount of concentrated brine into the charcoal to make the charcoal slightly moist. Then we have always repeated the above two steps until the beaker is filled with charcoal. In this process, we must remember to make sure that the graphite electrode is unexpectedly loosened. The outer shell of the battery is about to be manufactured, and the outer shell of this battery is the 100 ml beaker. If it is made with a slightly smaller beaker, the voltage will be lower, but the current is quite amazing.
