How about cylindrical lithium iron phosphate batteries? Detailed explanation of the advantages and disadvantages of cylindrical lithium iron phosphate batteries

Cylindrical lithium batteries can be divided into lithium cobalt oxide, lithium manganate, and ternary materials. The three types of material safety system batteries have their own advantages and disadvantages. The batteries are widely used in various fields such as computer notebooks, digital cameras, lighting equipment, electric toy enterprise products, power tool accessories, and handheld mobile energy.

So far, the key to the cylinder is the aluminum-shell cylindrical lithium iron phosphate battery. The outstanding performance of such a battery is high capacity, high output voltage, excellent charge-discharge cycle safety performance, relatively stable output voltage, large current discharge, and electric The chemical safety performance is relatively stable, the operation is safe and reliable, the working temperature range is wide, and it does not pollute the environment. Next, let's take a look at the advantages and disadvantages of cylindrical lithium iron phosphate batteries.

Advantages of cylindrical lithium iron phosphate battery:

1. The unity of the monomer is better. Cylindrical lithium batteries have long established a series of internationally unified standard specifications and models, and the processing technology is relatively mature and perfect, which is suitable for large-scale batch uninterrupted production and manufacturing.

2. The monomer itself has good mechanical properties. The specific surface area of the cylinder is large, and the heat pipe has a very good heat dissipation effect, and can obtain higher bending strength;

3. The technology application is mature and perfect, and the cost is low. The metal shell of the battery has high compression resistance, and it is not easy to produce conditions such as square shape and flexible packaging battery swelling during the entire operation.

4. The single energy is small, and the probability of frequent accidents is small. When an accident occurs, the form is easy to control. The cylindrical battery is usually a sealed battery, and there will be no maintenance problems during the entire operation.

Disadvantages of cylindrical lithium iron phosphate battery:

1. Cylindrical lithium batteries have limited processing technology for electric welding of multi-pole ears, so the rate characteristics are slightly weaker, and there is no such outstanding rate performance.

2. The specificity of organic chemistry at the corners of the cylindrical battery is poor, and the performance of the battery under long-term operation is relatively significant.

3. It has poor compatibility with common batteries, because it usually can be replaced with lithium-ion batteries when three common batteries (3.6V) are used.

4. There must be a unique protection circuit to avoid overcharging or overdischarging;

5. The cost is relatively high, mainly due to the high price of battery cathode material LiCOO2. With the continuous and rapid development of cathode technology applications, LiMn2O4, LiFePO4, etc. can be used as cathodes, so it is hoped that the cost of lithium-ion batteries can be greatly reduced.
