The lithium iron phosphate battery can be used as a starting battery. It is currently the only type that does not catch fire after passing oven temperature, overload and short circuit tests. The element iron is the product of countless fusions. It is currently the most stable element, so lithium iron batteries are very safe. Differences in Characteristics It is well known that lead acid batteries have the shortest lifespan and will be discarded after an average of 350 full charges and discharges. The reason is that each discharge process will form different degrees of plate vulcanization, especially in winter. , multilayer crystals appear, a considerable part of which cannot be restored during the charging process.
1. Energy storageBenefits of batterieslithium iron phosphate
1. , the service life is more than 2000 times, and the 3C service life reaches more than 800 times. Under the same conditions, lithium iron phosphate batteries can be used for 7 to 8 years.
2. Safe to use. Lithium iron phosphate batteries have undergone strict safety testing and will not explode even in violent collisions.
3. Fast loading. Using a special charger, the battery can be fully charged at 1.5°C in 40 minutes, and the starting current can reach 2°C.
4. Lithium iron phosphate batteries are resistant to high temperatures. The thermal peak of lithium iron phosphate batteries can reach 350 to 500 degrees Celsius. The operating temperature range is wide (-20~75℃) and high. temperature (60 ℃).
5. Lithium iron phosphate batteries have large capacity, and their energy density is 3-4 times that of lead-acid batteries, 2.5 fois that of nickel-cadmium batteries and 1.8 times that of nickel-metal. hydride batteries.
2. Disadvantages of lithium iron phosphate energy storage batteries
1. The lifespan of an iron phosphate battery is significantly less than that of a single battery. Compared with other batteries, the service life of lithium iron phosphate batteries has no obvious advantages. There are a large number of batteries on the used market that have been removed from the market before reaching their expected lifespan.
2. Poor performance at low temperatures. Capacity drops quickly when below 0 degrees and cycle performance is extremely poor at low temperatures.
3. During the sintering process when preparing lithium iron phosphate, iron oxide can be reduced to elemental iron in a high temperature reducing atmosphere. Elemental ironIt can cause micro-short circuits in batteries and is the most taboo substance in batteries.
Applications of lithium iron phosphate batteries
1. Applications in the new energy automobile industry
Lithium iron phosphate batteries are safe because their advantages such as safety and low cost are widely used in passenger cars, buses, logistics vehicles, low-speed electric vehicles, etc. Although, in the current field of new energy passenger vehicles, affected by the national subsidy policy for new energy vehicles, relying on the advantages of energy density, ternary batteries once occupied a dominant position, but the Lithium iron phosphate batteries always occupy an irreplaceable advantage in passenger cars, logistics vehicles and other fields. Last numberILithium iron phosphate batteries are shown to account for half of total battery shipments.
2. Application to starting power supplies
In addition to the characteristics of power lithium batteries, lithium iron phosphate starting battery also has the ability to produce instant high power, using less energy. More than a kilowatt hour. The lithium type battery replaces the traditional lead acid battery, and the BSG motor replaces the traditional starter and generator. It not only has idle start and stop functions, but also has stop and coast energy, coasting and braking. recuperation, acceleration assist and electric cruise functions.
3. Applications in energy storage market
Lithium iron phosphate batteries have high operating voltage, high energy density, long lifee life, low self-discharge rate, no memory effect and are green and environmentally friendly. It has a series of unique advantages and supports infinite expansion. It is suitable for large-scale electrical energy storage and has good application prospects in the fields of secure grid connection of renewable energy power plants, grid peak shaving, distributed power plants, UPS power supplies , emergency power systems and other fields.
