- Safety factor of lithium iron phosphate battery
Among lithium-ion batteries, lithium-ion batteries with lithium iron phosphate as the cathode material have the best safety factor. The important reason is that Lifepo4 has good oxygen-retaining ability under high temperature standards. Even if the temperature is above 500c, it will not lose oxygen, which is much higher than lithium borate, lithium manganate and ternary materials. However, under abuse conditions, even lithium-ion batteries with LiFePO4 as the positive electrode may have safety issues. - The price of lithium iron phosphate battery
There are three pricing methods for lithium iron phosphate batteries, one is the price of only buying lithium iron phosphate battery cells, the other is the price of lithium iron phosphate batteries without protection board, and the last is the price of lithium ion batteries with protection board. price. These three methods are completely different in price. Now, let us understand: - Only buy lithium iron phosphate battery cells
Lithium-ion batteries have brand new lithium-ion batteries and professional lithium-ion battery upgrades. Li-ion batteries are new products in the whole process from raw materials to cost. Li-ion batteries such as lithium-ion batteries are used in secondary applications. For example, backup power supplies for communication base stations, electric vehicles, and sub-3C products. Therefore, when some people buy lithium-ion batteries, they often find that the price difference between different stores is a bit big, and some even fluctuate from 8 yuan to 2 yuan. Low prices, most of them are professional lithium-ion batteries. Of course, it is not good to say that a professional lithium ion core depends on the actual product application requirements. - Only buy lithium iron phosphate battery without protection board
In this way, it is also an upgrade of a brand new rechargeable battery and a stepping battery, so in the case of purchase, the customer’s best to grasp the price of the rechargeable battery dealer is the price of a new upgraded lithium phosphate battery or a stepping battery the price of. Generally speaking, the price of the cascade battery is similar to that of the newly upgraded battery. The lithium-ion battery rechargeable battery without lithium-ion battery protection board is based on a single low-voltage rechargeable battery. The number of parallel and series connection of lithium-ion batteries is based on the number of lithium-ion batteries. Because lithium-ion batteries are not consistent in consistency Very good, the total number of lithium-ion batteries that can be used in series and parallel circuits is relatively limited. The general operating voltage and capacity of lithium-ion batteries are not large, and they are easy to become larger. Generally speaking, the current price of lithium-ion phosphate batteries produced by lithium iron phosphate battery manufacturers is based on the upgrade of new rechargeable batteries, and the supply is basically brand-new batteries, the price is about 8 yuan per time; do echelon phosphoric acid Lithium-iron battery manufacturers generally quote 1Ah around 6 yuan, and some even cost around 5 yuan 1Ah. - Lithium iron phosphate battery plus protection board
Lithium phosphate rechargeable batteries use lithium-ion battery protection boards. This type of battery is generally 12V higher than a single rechargeable battery or lithium-ion battery pack, such as a battery with a newly upgraded and down battery. The price difference of the battery is the same as the second point above. The price difference is the key to the battery protection board, which depends on the difference in the function and cost of the electronic device. Therefore, due to different manufacturers, the price of lithium-ion battery rechargeable batteries and lithium-ion battery protection boards will vary greatly. But in any case, when we buy rechargeable lithium-iron-phosphate batteries, we have to understand our specific requirements, and then choose the product that best suits our economic interests.
