What do you know about lithium battery?

The lithium battery: It is a secondary battery (rechargeable battery) that depends mainly on the movement of lithium ions between the positive and negative electrodes. During loading and unloading Li + is intercalibrated between the two electrodes and de-calibrated: during loading Li + is de-calibrated by the positive electrode and embedded by the electrolyte into the negative electrode and the negative electrode is in a lithium-rich state; It's the other way around when you unload.

What are the specific conditions for the purchase of lithium batteries?

1. Is the capacity clearly identified? lithium battery without clearly marked capacity (such as 1000 mAh or 1000 mAh) are likely to use inferior batteries or recycled batteries. Many cheap batteries on the market are made from recycled batteries. Although they are cheap, they have a short life span and unstable quality. Careful use to avoid damaging the phone.

2. Is there a guarantee for standby time? The standby time refers to the duration of use after putting the lithium battery into the phone until the next charge. In general, the batteries sold on the market cannot guarantee standby time for the customer. This is because the battery quality is unstable. Many cheap batteries use battery cores of poor quality, so the standby time is very short.

3. Whether to install a security card. Without the protective plate, lithium bacteria are in danger of deformation, leakage and explosion. In the fierce price-cutting competition, various companies are looking for or renouncing cheaper circuit boards, which floods the market with explosive lithium batteries. Consumers cannot tell by the appearance whether a safety board exists, so it is best to buy a serious trader.

What are the benefits of lithium batteries?

1. The self-discharge rate of the lithium battery is very low, which is one of the most outstanding advantages of the lithium battery. Generally, it can reach less than 1% / month, which is less than 1/20 of the nickel hydrogen battery;

2. The weight of the lithium battery is light and the weight is approximately 1/6-1/5 of the lead acid product under the same volume;

Three. lithium battery has a strong ability to adapt to high and low temperatures, it can be used in an environment of -20'8451;-- 60'8451; after the process it can be used in an environment of -45'8451and

4. lithium batteries are very green and environmentally friendly. Whether produced, used or destroyed, they do not contain or produce toxic and harmful heavy metal elements and substances such as lead, mercury and cadmium.

5. The production process of lithium batteries basically does not consume water, which is very advantageous for countries with a water shortage.

What properties distinguish lithium batteries from other batteries?

1. High cycle life. Under normal conditions, the loading and unloading cycle of llithium batteries may exceed 500-fold and lithium-iron phosphate can reach the 2000-fold.

2. No memory effect The memory effect denotes the phenomenon that the capacity of the nickel cadmium battery decreases during the charge-discharge cycle. Lithium-ion batteries do not have this effect.

3. A constant current and constant voltage charger with a rated voltage of 4,2 V is used for quick charging, allowing the lithium batteries to be fully charged within 1,5 to 2,5 hours. during the newly developed lithium-iron phosphate battery, electricity can already be fully charged within 35 minutes.

Overall, the important role of lithium bacteria in our daily lives is perceived by more and more people. Shenzhen Sumry Electronics Co., Ltd. strives to offer high quality lithium batteries at reasonable prices, efficient production times and the most professional customer service.
