Lithium phosphate ion battery is one of the batteries of the new energy electric vehicle, and many iron lithium-ion battery packages have emerged in recent years, which leads to a lot of phosphate ion battery brands on the market, and the price is uneven. So how to judge the lithium iron phosphate ion battery, which brand is good, becomes a problem that battery users are more concerned. Let's let the battery manufacturer briefly tell us what is the sign of the lithium iron phosphate ion battery.

For consumers, regardless of the brand of the battery, the battery is prone to determining from the following aspects: 1. Safety of lithium iron phosphate ion batteries in lithium ion batteries, recognized by LifePo4 is positive The lithium ion battery of the material has the best safety performance. It is necessary to maintain the oxygen retention capacity of LifePO4 under high temperature conditions, even in a high temperature of more than 500 ° C, no oxygen, more than lithium diamine, lithium manganate, and three-yuan materials.

But under abusive conditions, even if LifePo4 is a lithium-ion battery, there will be safety issues. Second, the price of lithium iron phosphate ion batteries The price of lithium iron phosphate ion batteries has three quotes, one is only the price of only lithium iron phosphate ion battery cells, the other is the price of lithium iron phosphate ion battery does not add protective plate, the last one Is the price of the protector. The price of these three ways is completely different.

Let's take a detailed understanding: 1. Only buy the phosphate ion battery electrical iron lithium-ion battery cell has a new battery and a ladder battery. The new battery is from raw materials to the cost of the cost, the new product, The ladder battery cell refers to the electrical cell used in secondary use, such as the lithium iron phosphate ion battery for new energy vehicles.

After the battery is attenuated to a certain extent, it cannot meet the power or capacity of the car, but the battery is not bad, after a certain Repair adjustment, you can use it on the next level. Such as communication base station spare power, electric bicycle, part 3C product, etc. So some people often find that different merchants have a big difference, some or even 8 yuan 1AH to 2 yuan.

In the low quotation, most of them are lithium iron phosphate cells. Of course, it is not good to say that the battery cell is not good. This depends on the use of detailed products.

2, only buy the lithium iron phosphate ion battery does not protect the protector in such a form, there is a new battery and ladder battery, so when buying, the buyer is best to understand the price quoted by the battery provider is brand new. Price or ladder battery price or ladder battery. In general, the price quotation of the ladder battery is almost the conflict of the new battery.

The lithium iron phosphate ion battery of the non-protective plate is basically a battery of the monomer, and the electrical core is substantially in the range of the cell, since the lithium phosphate ion battery cell is not very good, Therefore, the number of batteries that can be used in series and in parallel is limited, and the general voltage and capacity of such batteries are not very large, it is easy to have problems. In general, there is currently a powerful lithium iron phosphate ion battery manufacturer, the quote of the lithium iron-free battery cells, the basics of supply are all new batteries, the price is about 8 yuan 1 is about time; do the lithium iron phosphate ion battery manufacturer , Quotation is generally around 6 块 1ah, some or even more about 1AH. 3, lithium iron phosphate ion battery plus protective plate phosphate ion battery plus protective plate, this battery is generally 12V single battery or battery pack, which is the same as a new and ladder battery.

Such battery price difference is the same as the second point above, and the difference is on the battery protection plate, the battery protection board difference is that the functional differences and components cost. Therefore, the price of lithium iron phosphate ion batteries will have a large difference because of different manufacturers. But no matter what, we must first understand our actual needs, then choose the product that is appropriate for your own economic benefits.

Third, the lithium iron phosphate ion battery life is currently about 2,000 lithium iron phosphate ion batteries in the market, which refers to the ideal number used in a smooth normal small current charge and the normal temperature environment, but actually uses different uses. In the case, the number of lithium iron phosphate ion batteries true life cycle is different. This is a matter of tight how to use the life of several different uses.

1. Use (1) Small current charging in the normal temperature environment of the lithium iron phosphate ion battery, which is basically used on the 3C electronics, and the lithium iron phosphate ion battery is used in this category. If the battery brand manufacturer is stronger, it is basically more than 2,000 cycle life; small lithium-ion battery manufacturers, the quality is more than 1,000 cycle life; (2) High-speed stable charge The use of high-magnification discharge is used, most of which is a power-type lithium-ion battery.

Most is used in the use of power supply to the motor, such as new energy vehicles, electric vehicles, fishing boat electromechanical power supply, etc. Since most of the lithium iron phosphate ion battery operate in high load conditions, speed up the battery material attenuation time, the cycle life is a very poorly declined battery, which may also be about 500 cycles; strong lithium iron phosphate ions Battery brand manufacturers, better use in equipment technology and materials, the quality of the battery will be better, but the loop life is around 800 times. (3) High-magnification instability charge and discharge use I think that the lithium iron-ion battery used in this case, the life will be shorter, 300 left and right is almost scrapped.

Unstable discharge used in batteries, low when high, low battery decay, makes it makers. 2. Lithium iron phosphate ion battery high temperature environments Using lithium iron phosphate ion battery high temperature performance is currently not very mature, operating temperature -20 ° C to 125 ° C, this temperature range is theoretical, actually use temperature range.

(1) Small current charging is normal in this category of lithium iron phosphate ion batteries, if the battery brand manufacturers are stronger, the quality is good, basically more than 1000 cycle life; small lithium ion battery Manufacturers, the quality is a little more than 500 cycle life; because of the use of high temperature, it is relatively large. (2) High-temperature stable charge and discharge use high temperature environment with high-magnification discharge, most of them are power-type lithium-ion batteries, mostly use in the use of power supply power supply, domestic powerful lithium-ion battery manufacturers processing Electrical cells are mostly used in new energy vehicles, electric vehicles, fishing boat electromechanical power, etc. Since most of the lithium iron phosphate ion battery operate in high load conditions, speed up the battery material attenuation time, the cycle life is a sharp decline, the quality of the poor quality, may also be 300 cycles; strong battery brand manufacturers, It will be better in the use of equipment technology and materials, and the quality of the battery will be better, but the loop life is about 500 times.

(3) High-temperature discharge and discharge and discharge use high-temperature discharge retroactivity unstable operation, the battery is more damage, the cycle service life is relatively low, and the detection of several battery manufacturers is discovered, 250 to 300 this, the battery is basically used. Can't. 3, lithium iron phosphate ion battery low temperature environment to use low temperature environments to be higher than high, on the current market situation, lithium iron phosphate ion batteries below -20 ° C- 40 ° C work, life is clear, discharge current range 0.

2c to 1C, discharge capacity 50% to 60%, temperature is low, the discharge ability. Therefore, there are not many low-temperature phosphate ion batteries used in the market, and the temperature range is from 20 ° C to 55 ° C, and the cycle life is 300 times. The above is about how to determine the basic knowledge points of the phosphate ion battery which brand, I hope to help everyone.
