The actual cycle life of lithium iron phosphate battery

Which is better for ternary lithium battery and lithium iron phosphate battery? Performance parameter comparison: actual life

When the quality of the iron- lithium battery is relatively good, the attenuation amount can be controlled within 5%, and the second year can be within 15%. The ternary type has a 7-10% decline in 1 year and 20-25% in 2 years. Of course, the specificity is also related to the use of the load and the frequency of use. This is just a rough expression.

Based on a variety of factors, the use characteristics of iron-lithium batteries can be expressed as follows: relatively large size, low temperature performance, can maintain a relatively gentle decay rate during the lifetime, generally 8 years or so is acceptable; Used in the South. Lithium iron phosphate batteries have a longer life than 8 years.

Characteristics of ternary lithium battery: small size, can accommodate larger capacity, less performance in winter, large initial capacity, obvious mileage advantage over iron-lithium battery, general life expectancy of about 8 years. But also depends on the cycle of full charge and discharge, ternary lithium can achieve 1200 full charge and discharge in daily use, if the charge and discharge cycle is long, there will be a higher life.

The two actually have similar life spans, and the performance is also very different. The difference is the development space. The lithium iron phosphate battery has reached the bottleneck, that is, it has reached the top of development, and the performance of the ternary lithium battery has not been fully developed. Therefore, it is better to choose a ternary lithium battery when choosing.

Hebei Xin Power New Energy Technology Co., Ltd. is a high-tech enterprise that carefully designs, produces and sells lithium battery management systems of various specifications and models. When you buy a lithium battery, you must look for a big brand. What is a big brand, quality is guaranteed, and a good after-sales service brand is a big brand. A lot of small manufacturers do not have the qualification for production. They assemble the products through patchwork. After the problem occurs, there is no after-sales. Therefore, to polish your eyes, you want to buy a lithium battery. Xin Power is the object of *.

The lithium iron phosphate power battery has a cycle life of more than 2,000 times and a standard charge (5 hour rate), which can reach 2000 times. The same quality lead-acid battery is "new half year, old half year, maintenance and maintenance for half a year", up to 1~1.5 years, while lithium iron phosphate battery is used under the same conditions, the theoretical life will reach 7~8 years. Considering comprehensively, the performance price ratio is theoretically more than four times that of lead-acid batteries. High-current discharge can be quickly charged and discharged with high current 2C. Under the special charger, the battery can be fully charged within 1.5 minutes of 1.5C charging, and the starting current can reach 2C, but the lead-acid battery has no such performance.

Many lithium carbonate batteries are used in many teaching laboratories. Since lithium iron carbonate batteries are becoming more and more widely used in their current lives, many people are very concerned about its development. Then the next series will make a simple introduction to the real life of lithium iron carbonate battery for everyone to understand.

Lithium iron phosphate battery life

1. Lithium iron carbonate batteries will have different discharge rates in different environments:

First of all, Xiaobian wants to introduce to you that lithium iron carbonate battery will have different discharge rates under different environments, and the minimum discharge rate can reach 0.5c, and the maximum discharge rate can reach 10c. No matter which kind of discharge rate the battery is, it will be very flat during the discharge process. Generally speaking, the voltage is very stable and will remain almost the same. Only when the lithium iron phosphate battery is about to end, it will be discovered. There will be a sharp decline, which can be very effective. Lithium iron carbonate battery has very good discharge characteristics, which means its real life is very long.

Second, the display of lithium iron carbonate battery under different temperature conditions:

Secondly, Xiaobian wants to introduce to you that lithium iron carbonate batteries will have different discharge phenomena at different temperature adjustments. We will set the temperature to below minus 20 degrees to 40 degrees. At this time, everyone will find carbonic acid. When the iron-lithium battery is at 23 ° C, the power generation capacity can reach 100%, and at 0 ° C, the discharge amount will be 78%, which means that its discharge rate of the three-iron lithium battery under different temperature conditions is Not the same, so when you want to estimate the description of the lithium iron carbonate battery, be sure to keep it in a certain temperature zone, so the estimated result is better, but he is at the limit. In terms of the expression under temperature conditions, the true life of lithium iron carbonate battery is very long, and it can reach more than 570 discharge cycles.

Third, the lithium iron carbonate battery put into the zero voltage experiment:

Putting the lithium iron carbonate battery into the zero voltage experiment, everyone will find that after the battery is fully charged in 3 days, it continues to discharge in such an environment, and it is found that its capacity will change very little. Explain that its capacity recovery is very good.

Finally, the production of lithium iron phosphate is a patent dispute in foreign countries, which is one reason why foreign electric vehicles generally use ternary cathode material lithium batteries.

The life of a lithium iron phosphate battery is not necessarily 4-5 times longer than that of a lead-acid battery. For a lead-acid battery with a relatively high technical content, the life expectancy is 5 years. However, the lithium battery has a problem of structural collapse due to the negative electrode material graphite, and will be scrapped even if it is left unused for five years. Different quality batteries cannot be compared, Nanfu and Oriental Star can be far away.

PS lithium battery production pollution is not comparable to lead-acid batteries, but it is definitely not environmentally friendly.

The related knowledge about the real life of lithium iron carbonate battery is introduced here. Through the introduction of Xiaobian and above, we can judge the real life of lithium iron carbonate battery through the discharge characteristics of lithium carbonate battery. Give everyone some help.
