Lithium-ion battery life
What is the maximum service life of lithium batteries?
How often should lithium batteries be stored?
How long is the lifespan of a lithium-ion battery?
How many years does a lithium battery last? How many kilometers can it run?
1. The service life of a lithium-ion battery is the number of uses.
2. The life of a lithium battery is "500 times", which does not refer to the number of charges, but a cycle of charge and discharge. A charging cycle means that all the battery's power is used from full to empty, and then charged from empty to full. This is not the same as charging once. For example, a lithium battery only uses half of its power on the first day, and then it is fully charged.
3. If the same situation persists the next day, that is, charge half of the charge, and charge it twice in total. This can only be counted as one charging cycle, not two. Therefore, it may often take several charges to complete a cycle. Each time a charging cycle is completed, the battery capacity decreases a little.
4. However, this reduction in power is very small. High-quality batteries will still retain 80% of their original capacity after being charged for many cycles. Many lithium battery-powered products are still in use after two or three years. Of course, lithium batteries still need to be replaced when their lifespan reaches the end.
5. The so-called 500 times means that the manufacturer has achieved about 625 rechargeable times at a constant discharge depth (such as 80%), reaching 500 charging cycles.
The service life of lithium batteries is about two to three years. Roughly speaking, the cycle of a lithium battery is about 500 times. Precautions for using lithium batteries:
1. Keeping lithium-ion batteries properly charged and discharged can extend battery life. Maintaining the lithium-ion battery power at 10%~90% is beneficial to protecting the battery. This means that when charging the batteries of digital products such as mobile phones and laptops, there is no need to reach the maximum value.
2. If the mobile phone battery needs to be charged every day, the reason may be that the battery is defective or it is time to "retire".
1. If the lithium battery is not used for a long time, it should be kept at 50%-60% state of charge. It should be recharged every 3 months and charged and discharged every six months.
2. During transportation, attention should be paid to moisture-proofing and moisture-proofing, and avoiding extrusion, collision, etc. to avoid battery damage.
3. It is prohibited to use or place the battery under high temperature (under scorching sunlight or in a very hot car), otherwise it may cause the battery to overheat, catch fire, or malfunction, and shorten its life.
1. The service life of lithium batteries is only two to three years.
2. Lithium batteries can generally be charged and discharged 300-500 times. It is best to partially discharge lithium batteries rather than fully discharge them, and try to avoid frequent full discharges. Once the battery rolls off the production line, the clock starts ticking. Regardless of whether you use it or not, the service life of lithium batteries is only two to three years.
3. "Lithium battery" is a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. Lithium metal batteries were first proposed and studied by Gilbert N. Lewis in 1912. In the 1970s, M.S. Whittingham proposed and began to study lithium-ion batteries. Because the chemical properties of lithium metal are very active, the processing, storage, and use of lithium metal have very high environmental requirements. Therefore, lithium batteries have not been used for a long time. With the development of science and technology, lithium batteries have now become mainstream.
4. Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium-ion batteries do not contain metallic lithium and are rechargeable. Lithium metal batteries, the fifth generation of rechargeable batteries, were born in 1996. Their safety, specific capacity, self-discharge rate and performance-price ratio are all better than those of lithium-ion batteries. Due to its own high technical requirements, companies in only a few countries are currently producing such lithium metal batteries.
1. Determining the life span of lithium battery is related to many factors, such as charging method and charging cycle, quality and running distance of electric vehicles, and quality of lithium battery.These will affect the life span of lithium battery.
2. If everything is normal, it can generally be used for 3 to 5 years. If the above situation occurs, the life span of the lithium battery cannot be determined. As for how many kilometers it can run, it is more difficult to estimate. This depends on the usage method, operating environment, and charging. The discharge method is related to the quality of the vehicle and battery, and it is difficult to determine how many kilometers it can run.
This ends the introduction about how many years the life of lithium-ion batteries is. Are lithium-ion batteries safe? I hope it will be helpful to everyone.
