How to disassemble and repair Chaowei 48v lithium battery

My electric car is made of 18650 lithium batteries. After using it for a while, the battery life is short, I disassemble the lithium battery, disconnect the battery protection cable , I charge each parallel battery to 4.2 volts, then plug it in. v. The protective version is arranged and resurrected to full health. Equalizers and balanced versions sold online are all misleading. I only used a cell phone charger, a protective version limiting the charging voltage and a multimeter. However, this operation requires some skill.

Process flow of lithium battery recycling equipment

Hello, let me explain the simple structure of lithium batteries to you. If you don't understand anything, you can continue asking questions.

The basic principle of the battery is a charging and discharging process in which the anode andthe cathode are inserted into the electrolyte. From what you describe it should be a prismatic battery and the lithium polymer battery should be foil.

In order to ensure complete contact between the electrodes and the electrolyte, the surface area of ​​the anode and cathode will be increased. The anode is aluminum foil and the cathode is copper foil, but their surfaces are covered with black film (electrode core process), then a separator is added in the middle of the cathode strips and d anode then rolled up. The product is called Jelly Roll. This thing is inserted into the aluminum box. The positive and negative electrodes are taken from the Jelly Roll. The negative electrode is connected to the middle of the battery core. the outer aluminum shell of the battery core. Then inject the electrolyte inside and laser seal it. Many steps were omitted.

So to answer the question you havedescribed, the silvery substance you mentioned should be aluminum flakes with a black coating. Next, there should be a solid piece of copper, also covered with a black membrane, and some white separating membranes. Made of coils. As for the composition of the coating, this is the main process and different manufacturers are different.

The new lithium battery disassembly and recycling equipment is based on the structure of positive and negative electrodes of lithium battery and the material characteristics of metal raw materials and powder of carbon used inside the battery. It uses hammer crushing and vibrating screens. Specific gravity airflow separation and separation is a combination of processes.

First, the remaining power of the used lithium-ion battery is discharged. The batThe discharged lithium battery is then shredded and crushed via the used lithium battery dismantling and recycling equipment, pulverizer and separator. separator, housing and fragments of positive and negative electrodes. The positive and negative electrode fragments are separated through the pulverizer and air separator to obtain copper-aluminum mixed metal particles, thereby realizing a fully automated recycling process of used lithium batteries.

Lithium battery waste recycling and processing equipment can extract and recycle heavy metals such as lithium, cobalt, copper and nickel in lithium-ion battery waste, which which is an effective way to improve the shortage of raw materials and reduce economic costs, improve economic efficiency.

The used lithium battery dismantling and recycling equipment is a production linerecycling production which dismantles, crushes and separates various discarded lithium batteries. It mainly uses physical and mechanical methods for recycling and treatment.
