The best workshop in the lithium battery factory is the pack workshop. According to relevant information, Pack workshop is mainly responsible for the processing and assembly of lithium battery packs. It mainly processes battery cells, battery protection plates, battery connection sheets, label paper, etc. into products required by customers through the Battery PACK process. combination.
Disposal methods for used batteries include heat treatment, wet treatment, superheated steam heat treatment, and solidification and landfill.
1. Heat treatment method
The heat treatment method also requires logistics sorting of nickel-cadmium batteries from used batteries, and the used batteries are heated in a vacuum environment. Mercury evaporates in a short time and can be recycledused ykey. Excess raw materials are then crushed, a magnet is used to extract the metallic iron, and then nickel and manganese are extracted from the remaining powder.
2. Wet processing method
The wet processing technology of used batteries is based on the principle that the metal materials and chemical substances contained in the battery are dissolved in the acid in addition to the batteries. , different types of batteries are all dissolved in sulfuric acid, and then various metal materials are extracted from the solution using ionic resin. The resulting raw materials are purer than the specific heat treatment method.
3. Superheated Steam Heat Treatment Method
Industrial metallurgical superheated steam method generally has two specific methods to treat used batteries. One is to heat oldlow-temperature batteries to extract volatilized mercury and recycle zinc and other heavy metals when ambient temperatures are higher; the other is to roast used batteries at high temperatures to volatilize volatile metal materials and oxides. the residues can be used as intermediate products in the metallurgical industry or otherwise processed.
4. Solidification and burial
Waste batteries are usually transported to special waste disposal sites, but this method is often very expensive and also results in waste. can be used as raw materials.
Classification of batteries
1. Dry Batteries
Dry batteries are also called manganese-zinc batteries. Batteries are different from voltaic batteries. In other words, the so-called manganese zinc refers to its raw materials. For the pDry islands made from other materials such as silver oxide batteries and nickel-cadmium batteries. The manganese-zinc battery voltage is 1.5V. Dry batteries consume chemical raw materials to generate electrical energy. Its voltage is not high, and the direct current it can generate cannot exceed 1A.
2. Lead acid battery
The battery is one of the most used batteries. Use a glass or plastic tank, fill it with sulfuric acid, and insert two lead plates, one is connected to the positive electrode of the charger and the other is connected to the negative electrode of the charger. , a battery is formed. There is a voltage of 2V between its positive and negative terminals. The advantage of batteries is that they can be used repeatedly. In addition, its internal resistance being extremely low, it can provide a significant current. Use it to power the car engineiture, and the instantaneous current can reach more than 20A.
3. Lithium battery
Lithium battery is a battery with lithium as the negative electrode. It is a new type of high-energy technology developed after the 1960s.Battery. According to the different electrolytes used, they are divided into high temperature molten salt lithium batteries, organic electrolyte lithium batteries, inorganic non-aqueous electrolyte lithium batteries, solid electrolyte lithium batteries and lithium water batteries.
