Why We Need to Propose Dead Lithium Battery Properly?
Lithium batteries are used in many electronic devices, such as cell phones, laptops, and power banks. They can be dangerous if not handled properly, especially when they are dead or no longer able to hold a charge.
One of the main reasons why it is important to dispose of dead lithium batteries properly is that they can potentially be a fire hazard. When a lithium battery is damaged or begins to degrade, it can overheat and catch fire. This can be especially dangerous if the battery is in close proximity to flammable materials, such as curtains or paper.
Proper disposal of dead lithium batteries also helps to protect the environment. Lithium batteries contain various chemicals and materials that can be harmful if they are not disposed of properly. For example, some lithium batteries contain heavy metals, such as cobalt and nickel, which can be toxic to plants and animals if they enter the soil or water supply.
Therefore, it is important to dispose of dead lithium batteries in a responsible manner, such as by taking them to a recycling center or special disposal facility. This helps to reduce the risk of fires and protect the environment from potential harm.
How to propose dead lithium battery?
There are a few steps you can follow to properly dispose of a dead lithium battery:
1. Check your local laws and regulations: Different countries and regions have different laws and regulations regarding the disposal of lithium batteries. It is important to familiarize yourself with these laws to ensure that you are disposing of the battery properly.
2. Find a recycling center or special disposal facility: Many cities and towns have recycling centers that accept lithium batteries for proper disposal. You can also check with your local government or waste management company to see if they have any special disposal facilities for lithium batteries.
3. Preparing the battery for disposal: Before disposing of the battery, it is important to prepare it properly. If the battery is still in a device, remove it carefully and wrap it in tape or packaging material to prevent it from coming into contact with metal objects. Avoid crushing, puncturing, or shorting the battery, as this can cause it to overheat or catch fire.
4. Transport the battery safely: When transporting the battery to the recycling center or special disposal facility, be sure to handle it carefully to avoid any accidents. It is a good idea to place the battery in a sturdy container or bag to prevent it from coming into contact with metal objects.
By following these steps, you can help to ensure that dead lithium batteries are disposed of properly and safely, protecting both people and the environment.
What factors will cause lithium battery die?
1.Capacity attenuation failure
“In the standard cycle life test, the discharge capacity should not be lower than 90% of the initial capacity when the number of cycles reaches 500. Or when the number of cycles reaches 1000 times, the discharge capacity should not be lower than 80% of the initial capacity. ” If the capacity declines sharply within the standard cycle range, it is a failure of capacity attenuation. The root cause of the failure of battery capacity attenuation lies in the failure of the material, and it is closely related to objective factors such as the battery manufacturing process and the battery use environment. From the material point of view, the main causes of failure are the structural failure of the cathode material, the transition growth of the negative electrode surface SEI, the decomposition and deterioration of the electrolyte, the corrosion of the collector fluid, and the trace impurities in the system.
2.Increased internal resistance
The increase in the internal resistance of lithium batteries will be accompanied by a decrease in energy density, a decrease in voltage and power, and failure problems such as battery heat production. The main factors that cause the internal resistance of lithium-ion batteries to increase are divided into key battery materials and battery use environment.
Thermal runaway refers to the rapid rise in the local or overall temperature inside the lithium-ion battery. The heat cannot be dissipated in time, accumulates in large quantities inside, and induces further side reactions. The factors that induce thermal runaway of lithium batteries are abnormal operating conditions, namely abuse, short circuit, high magnification, high temperature, extrusion, and acupuncture.
4.Internal short circuit of lithium battery
Internal short circuits often cause self-discharge of lithium-ion batteries, capacity attenuation, local thermal runaway, and safety accidents.
How to look after your lithium battery?
Avoid Temperatures Below 32°F (0°C) And Above 95°F (35°C)
Lithium batteries store electricity as a chemical. Therefore, their performance is affected by ambient temperature.
Below 32°F(0°C): cause metal deposition at the negative electrode, leading to a short circuit.
Above95°F(35°C): other parasitic reactions are promoted leading to degrade further
Do Not Charge It To 100%
Experimental studies shows that only charging your battery to 90% provides 2 to 5 times longer life compared to fully charged batteries.
Do Not Discharge It To 0%
Deep discharge promotes metal degradation, leading to short circuits that can irreversibly damage your lithium battery
Use Partial-Discharge Cycles
Partial discharge cycles happen when less than 50% of the battery capacity is discharged before charging. This will considerably extend your battery life. You can perform thousands of partial cycles before your battery starts to degrade
Do Not always fast charging
Even though lithium batteries are fit for quick charge with solar panels, high currents generate stress in the battery chemistry. The same happens with high discharging currents.
