In short, the design of the lithium battery R&D laboratory should comprehensively consider the laboratory layout, the ventilation system, the electrical power system and thehas fire protection. system, environmental protection facilities, experimental equipment, experimental benches and storage cabinets, as well as safety and other factors, to ensure the accuracy of experiments and the health and safety of experimental personnel.
18650 lithium battery (features, applications and safety precautions)
The tutorial for assembling a homemade 12v lithium battery is as follows :
Materials: 3 18650 lithium batteries, battery case or magnet.
1. When we prepare three lithium batteries, we must ensure that their models are the same and cannot be mixed. This is because different lithium battery models can have different chemistries, voltages and capacities, which can pose safety risks if mixed.
2. When assembling the battery box, we mustensure that the batteries are connected in series. This is because the voltage only increases when the batteries are connected in series. If other connection methods are used, such as parallel or mixed connection, the voltage will not increase and the voltage of the entire battery system will only be 4V.
3. After installing the battery, useThe voltmeter measured 12V and showed 12.33V.
4. The magnetic beads must be conductive, otherwise they must be wrapped with a layer of tin foil.
5. Connect the batteries in series, with the positive pole facing the negative pole, not the other way around.
6. After successfully assembling the battery box and connecting all the batteries, to ensure that the system is operating properly and obtaining the expected voltage, it is recommended to perform a voltage measurement. When measuring, you can use a voltmeter to read the box output voltager battery.
If all goes well, we should be able to see a 12V output. This proves that the battery box is connected correctly and the system is working as expected.
Precautions for using lithium batteries
1. Avoid overcharging and discharging:
Lithium batteries have certain charging and discharging requirements. the range, if exceeded, may cause permanent damage to the battery.
2. Avoid contact with high temperature environments:
Lithium batteries may expand, leak, catch fire, and present other safety issues in high temperature environments. -High temperature environments should be avoided.
3. Avoid short circuits:
A short circuit of the lithium battery can cause explosion and other serious consequences, so short circuits should be avoided as much as possibleduring use.
4. Proper storage:
Lithium batteries should be stored in a dry and well-ventilated environment, away from direct sunlight, and avoid storage near high temperature objects, at moisture and flammable and explosive.
5. Pay attention to the service life:
Lithium batteries have a certain service life after expiration, the battery should be replaced in time to avoid safety problems due to battery aging.
6. Pay attention to the production date:
When purchasing lithium batteries, you should choose products with a more recent production date to avoid purchasing expired or counterfeit products.
7. Pay attention to suitability:
Before using lithium batteries, you should first confirm whether the battery is suitable for the equipment or tools used to avoid safety problems caused bya mismatch.
8. Pay attention to how you transport it:
If you need to transport a lithium battery, you should put it in its original packaging to avoid safety problems caused by improper transportation. method.
9. Pay attention to recycling:
When the lithium battery is no longer used, it should be sent to the designated recycling point for recycling and avoid throwing it away or throwing it away at will. avoid Causing environmental pollution and safety hazards.
