How long is the real life of lithium iron phosphate battery?

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%. For the ternary type, the decline is 7-10% 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: 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 and 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 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 teaching laboratories now use lithium iron carbonate batteries. Since lithium iron carbonate batteries are becoming more and more widely used in the present life, many people are very concerned about its development. Then the next small series will make a simple introduction to the real life of lithium iron carbonate battery for everyone to understand.

Lithium iron phosphate battery real life

A, carbonic acid iron-lithium batteries in different environments have different discharge rate:

Small make up to introduce the first that the carbonate iron-lithium batteries under different environments, it will have different discharge rate, and the minimum discharge rate can reach 0.5 c, maximum discharge rate can reach 10 c, and this kind of battery in either discharge rate, in the process of discharge will be very smooth, in general voltage is very smooth, almost will remain the same, only when the carbonic acid iron-lithium battery power end, will find it will be a sharp decline phenomenon, this can be very effective, carbonic acid iron-lithium batteries it has very good discharge characteristics which means it's real life is very long.

Lithium iron phosphate battery real life

Second, carbonic acid iron-lithium batteries under different temperature conditions showed that:

Secondly, I want 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 iron carbonate. When the 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 the discharge rate of the three iron lithium battery is different under different temperature conditions. Therefore, when you want to estimate the situation of lithium iron carbonate battery, you must keep it in a certain temperature zone, so the estimated result is better, but he is in extreme temperature conditions. In terms of performance, the true life of lithium iron carbonate battery is very long, and it can reach more than 570 discharge cycles.

Third, carbonic acid iron-lithium batteries in zero voltage experiment:

Putting the lithium iron carbonate battery into the zero-voltage experiment, you 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. 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.

P.S. lithium battery with lead-acid battery can produce pollution, but absolutely not environmental protection.

The relevant knowledge about the real life of lithium iron carbonate battery is introduced here. Through the above introduction, we can judge the real life of lithium iron carbonate battery through the discharge characteristics of lithium carbonate battery. I hope the above introduction can bring some help.
