Detailed explanation of the production process of AGV/RGV lithium batteries
With the continuous improvement of the level of industrial automation, automatic guided vehicles (AGV) and rail-guided vehicles (RGV) are increasingly widely used in modern manufacturing. As the core power source of these intelligent vehicles, the performance of lithium batteries directly affects the operating efficiency and reliability of the vehicles. This article will introduce the production process of AGV/RGV lithium batteries in detail.
1. Raw material preparation
The main raw materials of lithium batteries include positive electrode materials, negative electrode materials, diaphragms, electrolytes, and shell materials. Before production begins, these raw materials need to be strictly inspected and screened to ensure that their quality and performance meet production requirements.
1.1 Positive electrode materials
Positive electrode materials are usually composed of lithium metal oxides, such as lithium iron phosphate (LiFePO4) or lithium nickel manganese cobalt oxide (NMC). These materials have high energy density and good cycle stability.
1.2 Negative electrode materials
Negative electrode materials are mainly composed of graphite or other carbon-based materials, which can effectively embed and deintercalate lithium ions to ensure the charging and discharging efficiency of the battery.
1.3 Diaphragm
The diaphragm is a microporous film that separates the positive and negative electrodes while allowing lithium ions to pass through. It is usually made of polyethylene or polypropylene.
1.4 Electrolyte
The electrolyte is the medium for lithium ions to move between the positive and negative electrodes, usually a mixture of organic solvents and lithium salts.
1.5 Shell material
The shell material needs to have good mechanical strength and chemical stability. Commonly used materials include steel, aluminum alloy or plastic.
2. Battery cell manufacturing
2.1 Preparation of positive and negative electrodes
First, the positive and negative electrode materials are mixed with conductive agents and binders respectively to form slurry. Then the slurry is coated on metal foil (usually aluminum foil and copper foil), and after drying, calendering and other processes, positive and negative electrode sheets are formed.
2.2 Diaphragm assembly
Insert a diaphragm between the positive and negative electrodes to ensure safe isolation inside the battery.
2.3 Winding or stacking
Wrap the positive and negative electrodes and diaphragms in a certain order to form a battery core or stack them into a layered structure.
2.4 Packaging
Put the wound or stacked battery core into the shell, inject the electrolyte, and then seal it to form a battery unit.
3. Battery assembly
3.1 Single cell test
Carry out charge and discharge tests on single cells to screen out batteries with qualified performance.
3.2 Battery module assembly
Connect multiple single cells through busbars or wires to form a battery module. In this process, a protection board needs to be installed to realize protection functions such as overcharge, over discharge, and short circuit.
3.3 Battery management system (BMS) integration
Integrate the battery management system into the battery module to realize real-time monitoring and management of the battery status.
3.4 Battery Pack Testing
The assembled battery pack is fully tested, including performance testing, safety testing, etc., to ensure the reliability and safety of the battery pack.
4. Finished Product Inspection and Packaging
4.1 Finished Product Inspection
The finished battery is subjected to final quality inspection, including appearance inspection, capacity testing, cycle life testing, etc.
4.2 Packaging
The batteries that pass the inspection will be properly packaged for transportation and storage. The packaging materials should have shockproof, waterproof, moisture-proof and other characteristics.
5. Shipping
AGV/RGV lithium batteries that have passed strict inspection will be boxed and sent to the customer's designated location, ready for use.
Summary: The production of AGV/RGV lithium batteries is a complex and delicate process involving multiple key steps and technologies. Every link requires precise control to ensure the performance and safety of the final product. With the continuous advancement of technology and the growth of market demand, the production process of lithium batteries is also continuously improving to meet higher standards of application requirements.
