Which lithium iron phosphate battery is good?

Regarding consumers, regardless of the brand of the battery, the quality of the battery is critically judged from the following aspects: 1. The safety of lithium iron phosphate batteries is among lithium batteries. It is recognized that LiFePO4 is used as the positive electrode material. Lithium batteries have the best safety performance. The important reason is that LiFePO4 has a good oxygen retention capacity under high temperature conditions, and it will not lose oxygen even at high temperatures exceeding 500°C, which is much higher than lithium borate, lithium manganate and ternary materials. However, under abuse conditions, even lithium batteries with LiFePO4 as the positive electrode will have safety issues. 2. The price of lithium iron phosphate battery There are three ways to quote the price of lithium iron phosphate battery. 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 one is with protection board. s price. The prices of these three methods are completely different. Let’s get to know in detail below: 1. Only buy lithium iron phosphate battery cells. There are brand-new batteries and echelon batteries for lithium iron phosphate batteries. Brand-new batteries are new products in the process from raw materials to cost, echelon batteries. The core refers to the secondary battery, such as the lithium iron phosphate battery used in new energy vehicles. After the battery decays to a certain extent, it cannot meet the power or capacity for the car, but the battery is not broken and has been repaired and adjusted. , Can be used on the next level of electrical equipment. For example, backup power supply for communication base stations, electric bicycles, and some 3C products. Therefore, when some people buy batteries, they often find that the quotations of different merchants are a bit different, and some even have a gap of 8 yuan 1Ah to 2 yuan. The price is too low, most of them are ladder lithium iron phosphate batteries. Of course, it does not mean that the echelon battery is not good. This depends on the detailed product usage requirements. 2. Buying only lithium iron phosphate batteries without the protection board. In this form of purchase, there are also differences between brand new batteries and ladder batteries. Therefore, when buying, the buyer should first know that the price quoted by the battery supplier is brand new phosphoric acid. The price of iron-lithium batteries is still the price of cascade batteries. Generally speaking, the price quotation of the cascade battery is basically a half-fold of a brand new battery. The lithium iron phosphate battery without protection board is basically a single low-voltage battery, and the number of parallel and series cells is basically within the number range, because the lithium iron phosphate battery cell is not very good in terms of consistency, so it can The number of batteries used in series and parallel is limited, and the voltage and capacity of such batteries are generally not very large, and problems are prone to occur when they are large. Generally speaking, the current price of lithium iron phosphate battery cells processed by powerful lithium iron phosphate battery manufacturers are basically brand new batteries, and the price is about 8 yuan 1 on time; for ladder lithium iron phosphate battery manufacturers, the quotation is Generally, 1Ah is around 6 yuan, and some are even 1Ah around 5 yuan. 3. Lithium iron phosphate battery plus protection board. Lithium iron phosphate battery plus protection board. This kind of battery is generally a single battery or battery pack above 12V. This type of battery is divided into brand new and echelon batteries. The price difference of such a battery is the same as the second point above. The price difference is critical on the battery protection board, and the difference in the battery protection board lies in the functional difference and the cost of components. Therefore, the price of lithium iron phosphate battery plus protection board will vary greatly between different manufacturers. But no matter what, when we buy lithium iron phosphate batteries, we must first understand our actual needs, and then choose products that are suitable for our own economic benefits.
