Ternary lithium battery and iron phosphate lithium battery which good? Comparison of performance parameters: actual life
When the quality of lithium iron battery is relatively good, the 1 attenuation can be controlled within 5%, and the second year can be within 15%. For the ternary type, the 1-year decline is 7-10%, and the 2-year decline is 20-25%. Of course, the specific and use load, use frequency has a relationship, here is just a general statement.
Comprehensive of various factors, the use of lithium iron battery characteristics can be roughly expressed as: relatively large size, low temperature performance is not good, can maintain a relatively gentle decay rate in the life period, generally used for about 8 years is OK; But if you use it in the South. Lithium iron phosphate batteries last a bit longer than eight years.
Ternary lithium battery features: small size, can install a larger capacity, winter performance decline is not much, the initial capacity is larger, than iron lithium battery has obvious mileage advantage, the general life of about 8 years. But also to see the complete charge and discharge cycle, ternary lithium in daily use can reach 1200 times of complete charge and discharge, if the charge and discharge cycle is long, there will be a higher life.
In fact, the life of the two is almost the same, the performance is very little difference, the difference is the development space, lithium iron phosphate battery has reached the bottleneck, that is, to the top of the development, and a lot of performance of ternary lithium battery has not been fully developed. Therefore, it is better to choose ternary lithium battery when choosing.
Hebei Xin Power New Energy Technology Co., LTD is a high-tech enterprise specializing in the design, production and sales of lithium battery management systems of various specifications. When you buy lithium batteries, be sure to look for big brands. What is a big brand, quality assurance, good after-sales service brand is a big brand. A lot of small manufacturers do not have production qualifications, through piecing together to assemble products, to the problem after no after-sales at all, so, to polish your eyes oh, want to buy lithium batteries, Xin power is the object of the first.
And lithium iron phosphate power battery, cycle life reaches more than 2000 times, standard charge (5 hours rate) use, can reach 2000 times. Lead-acid batteries of the same quality are "new half a year, old half a year, maintenance and maintenance for another half a year", at most 1~1.5 years, and lithium iron phosphate batteries used under the same conditions, the theoretical life will reach 7~8 years. All in all, the performance price is more than four times that of lead-acid batteries in theory. High current discharge can high current 2C fast charge and discharge, under the special charger, 1.5C charge within 40 minutes can make the battery full, starting current up to 2C, and lead-acid battery has no such performance.
Lithium iron carbonate batteries are now used in many teaching laboratories. Because lithium iron carbonate battery is more and more widely used in today's life, so many people are very concerned about its development. Then next Xiaobian will make a simple introduction to the real life of lithium iron carbonate battery for everyone to understand.
Real life of lithium iron phosphate battery
First, lithium iron carbonate battery in different environments will have different discharge rates:
Small make up to introduce the first that the carbonic acid lithium iron batteries it under different environments, 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 power generation of lithium iron carbonate battery is about to end, it will be found that it will have a sharp decline phenomenon, which can be very effective to explain that lithium iron carbonate battery it has very good discharge characteristics, which shows that its real life is very long.

Two, lithium iron carbonate battery display under different temperature conditions:
Second small make up to introduce, carbonic acid lithium iron batteries in different adjustment of temperature, also can have different discharge phenomenon, we have to set the temperature to minus 20 to 40 degrees or above, at that time everyone will find carbonic acid lithium iron batteries in 23 ℃, power capacity can reach 100%, and the amount of discharge at 0 ℃ 78% more, This means he SanTie lithium battery in different temperature under the conditions of its discharge rate is different, so we want to estimate the carbonic acid lithium iron batteries it illustrates, be sure to keep it in the temperature of a particular area, so that the estimated result is good, but he is under the condition of the limit temperature of form, The real life of lithium iron carbonate battery is very long, can reach more than 570 discharge cycles.

Three, lithium iron carbonate battery to zero voltage experiment:
Lithium iron carbonate battery in the zero voltage experiment, we will find that three days after the battery charge, in such an environment to continue the cycle of discharge, found that its capacity will change very small, which shows that its capacity recovery is very good.
Finally, there are patent disputes over the production of lithium iron phosphate in foreign countries, which is also one reason why three-way cathode lithium batteries are commonly used in electric vehicles abroad.
The LIFE OF lithium iron phosphate battery is not necessarily 4-5 times longer than that of lead-acid battery. For the lead-acid battery with relatively high technology content, the life of 5 years is not a problem. And lithium battery due to the structure collapse of the anode material graphite, even if it is not used for five years will be scrapped. Different quality batteries can not be compared, Nanfu and Eastern Star are far from the same.
