What about lithium iron phosphate battery packs? What are the advantages of lithium iron phosphate batteries? What are the benefits of lithium iron phosphate batteries?
Lithium iron phosphate battery refers to a lithium ion battery that uses lithium iron phosphate as a positive electrode material. Lithium iron phosphate batteries are lithium-ion secondary batteries, and one of their main uses is as a power battery. Today, the editor will tell you about the advantages and disadvantages of lithium battery packs, industry applications, recycling, meaning, etc. Don't miss it.
Cunneng Electric Lithium Iron Phosphate battery pack has the advantages of small size, light weight, high energy density, long life, environmental protection, no memory effect, etc. Energy storage lithium battery packs are also lithium iron phosphate batteries. Compared with domestic manufacturers, they have relatively large advantages in battery consistency, stability, safety, environmental protection, and cycle life, which are attractive to downstream manufacturers. The force is also great.
The meaning of lithium iron phosphate battery pack
The discharge voltage is stable, safe (no combustion, no explosion), life (cycle times), and no pollution to the environment. Lithium iron phosphate battery is the best, and it is currently the best high-current output power battery.
The advantages of lithium iron phosphate battery pack
✔Long service life, the cycle life of long-life lead-acid batteries is about 300 times, and the maximum is 500 times, while the cycle life of lithium iron phosphate power batteries is more than 2000 times, and the standard charge (5 hour rate) can reach 2000 Times.
✔Good high temperature performance, the peak value of lithium iron phosphate electric heating can reach 350℃-500℃, while lithium manganate and lithium cobaltate are only around 200℃. Wide operating temperature range (-20C--+75C), with high temperature resistance, lithium iron phosphate electric heating peak can reach 350℃-500℃, while lithium manganate and lithium cobaltate are only around 200℃.
✔ It is safe and reliable. The P-O bond in the lithium iron phosphate crystal is stable and difficult to decompose. Even at high temperature or overcharge, it will not collapse and heat like lithium cobalt oxide or form strong oxidizing substances, so it has good safety.
✔ There is no memory effect. When the rechargeable battery is always fully charged, the capacity will quickly fall below the rated capacity. This phenomenon is called the memory effect. Like Ni-MH and Ni-Cd batteries, there is memory, but lithium iron phosphate battery packs do not have this phenomenon. No matter what state the battery is in, it can be charged and used at any time without having to discharge it before charging.
✔Small size, light weight, large capacity, the volume of the lithium iron phosphate battery of the same specification and capacity is 2/3 of the volume of the lead-acid battery, and the weight is 1/3 of the lead-acid battery. It has a larger capacity than ordinary batteries (lead-acid, etc.).
✔ Green and environmental protection, lithium battery packs are considered to be free of heavy metals and rare metals (the nickel-hydrogen battery requires rare metals), non-toxic (SGS certified), non-polluting, in line with European RoHS regulations, and an absolute green battery certificate.
✔Good charging and discharging characteristics, the conversion efficiency of charging and discharging lithium battery packs can be greater than 97%, and the conversion efficiency of charging and discharging lead-acid batteries is about 80%. For the same fully charged lithium iron phosphate battery, at the same temperature, using different rates of discharge current, its discharge output characteristics are very stable.
✔ Fast charging: high current 2C fast charge and discharge, the battery can be fully charged within 40 minutes under 1.5C charging under the special charger, the starting current can reach 2C, but the lead-acid battery does not have this performance now.
Disadvantages of lithium iron phosphate battery pack
1. In the sintering process during the preparation of lithium iron phosphate, iron oxide may be reduced to elemental iron in a high-temperature reducing atmosphere.
2. There are some performance defects in lithium iron phosphate battery packs, such as poor low-temperature performance, low tap density and compact density, resulting in low energy density of lithium-ion batteries.
3. The cost of material preparation and battery manufacturing costs are relatively high, the battery yield is low, and the consistency is poor.
4. Intellectual property issues. At present, the basic patent of lithium iron phosphate is owned by the University of Texas, while the carbon coating patent is applied by Canadians. These two basic patents cannot be bypassed. If royalties are included in the cost, the cost of the product will be further increased.
How to recycle lithium battery packs
In order to realize the cascade utilization of power batteries, it is necessary to establish a full life cycle monitoring system for power batteries to conduct real-time assessment of the battery's health status. It is necessary to put the evaluation and monitoring of the battery in the whole life cycle of the battery, instead of waiting for the battery to be eliminated before testing and screening. Commonly used methods for recycling waste lithium batteries include hydrometallurgy, pyrometallurgy, and mechanical and physical methods. Compared with wet method and fire method, mechanical physical method does not require the use of chemical reagents, and has lower energy consumption. It is an environmentally friendly and efficient method.
Application field of lithium iron phosphate battery pack
Lithium iron phosphate is currently the safest cathode material for lithium-ion batteries as a positive electrode material for lithium battery packs. Due to its safety and stability, lithium iron phosphate batteries have become an important development direction for lithium-ion power batteries. Products are widely used in electric new energy vehicles, energy storage fields, small computer rooms, weak current rooms and other room sub-systems, new energy outdoor sites, communication base stations, indoor and outdoor non-air-conditioned sites, radio and television, military, petroleum and meteorological and other unmanned sites.
With its many advantages, the lithium iron phosphate battery pack has great potential in the application of power-type lithium-ion batteries. As the global trend of vigorously developing new energy vehicles has taken shape, my country's lithium battery pack status will continue to rise in the future, and sooner or later it will become a dark horse in the industry.
