Why do lithium batteries wear out after prolonged use?

Introduction Why do lithium batteries wear out after prolonged use? Do lithium batteries start to wear out as soon as they leave the factory. This is due to the chemical nature of lithium batteries, meaning the active material inside will continue to grow over time.

Why do lithium batteries wear out after prolonged use?

Lithium batteries begin to wear out as soon as they leave the factory.

This is due to the chemical properties of lithium batteries, i.e. the internal active materials will continue to reduce their activity over time and parts that gradually become inactive lose their function electrical energy storage. .

This is what we mean by battery loss.

I can give the poster some data on the duration and wear level of the lithium battery.

I have an old laptop. I bought it in 2007 and it is 11 years old. I use it almost every day, the battery lost 41%. calculation, the average annual loss rate is 3.73%

How long will it take for lithium batteries to be discarded if they are not charged?

1. (gel lead-acid batteries) are cheap and have stable performance. Most electric vehicles on the market use thisBattery Type.

2. Lithium-ion battery (often called lithium battery) has a higher cost, but has large specific energy, high specific power, low self-discharge, no memory effect, good cycle characteristics and operating temperature. Range ; no environmental pollution and other benefits

3. Crystal Gel battery has high cost and stable performance. There are not many electric vehicles using this type of battery on the market, and only a few companies are equipped with them. with these high performance batteries, the batteries have the highest safety factor. The advantage of much longer service life than the first two types of batteries and the advantage of self-healing function also constitutes the leading position in the industry. The advantage is that lead acid batteries do not have them, and the disadvantages. battery delaminationlead can be avoided.

Lithium-ion batteries

Primary batteries: disposable batteries that are discarded after use and cannot be reused, such as carbon-zinc batteries, alkaline batteries, acid batteries mercury and lithium batteries. .

Secondary batteries: rechargeable and reusable, such as: nickel-cadmium rechargeable batteries, nickel-metal hydride rechargeable batteries, lithium rechargeable batteries, lead-acid batteries, solar cells, crystalline gel and lithium batteries iron phosphate. batteries.

In theory, an unused cell phone battery will lose 5% of its power per week, but there is no specific time limit because the lithium battery will be discarded for a long time. of use. It depends on the situation, the type of brand, the ingredients and even the environment in which it is placed.

After the lithium battery is exhausted, if it is not charged, itThe will be over discharged due to self-discharge during the placement process. After six months to a year, the lithium battery will be lost. its activity and become extremely undurable, close to scrap metal.

It is generally strictly prohibited to discharge or overcharge lithium batteries. Excessive discharge at low voltage or self-discharge reaction will cause lithium-ion active materials to decompose and destroy, which may not be the case. Any form of overcharging will cause serious damage to battery performance or even an explosion.

Detailed information:

1. Lithium batteries are charged and discharged regularly. this means charging fully, then discharging, then charging to more than 70% power. The general voltage is around 3.85V. It is ideal to store in this condition. Avoid humidity and heat.

2. The duration ofLithium battery life mainly depends on the number of charging and discharging times of the battery. For example, the battery can be charged several times a day. The battery is typically used 300-500 times. . For domestic products, good ones are generally 600 times, and good ones can reach 1,200 times or more.

3. Due to the highly active chemical properties of lithium metal, 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.
