Eight advantages of lithium iron phosphate batteries

　　A: Improvement of safety performance

　　Even at high temperature or overcharge, lithium iron phosphate will not collapse and heat up like lithium cobalt oxide or form strong oxidizing substances, so it has good safety, and its overcharge safety is better than that of ordinary liquid electrolyte lithium cobalt oxide. The battery has been greatly improved.

　　B: Improved lifespan

　　The cycle life of long-life lead-acid batteries is about 300 times, and the highest is 500 times, while the cycle life of lithium iron phosphate power batteries is more than 4000 times. The actual application life of lead-acid batteries is only 2 years at most, while the theoretical life of lithium iron phosphate batteries will reach 8 years when used under the same conditions.

　　C: Good high temperature performance

　　The thermal peak of lithium iron phosphate batteries can reach 350℃-500℃, while lithium manganate and lithium cobaltate are only around 200℃. The lithium iron phosphate battery has a wide operating temperature range (-20℃-+75℃).

　　D: large capacity

　　It has a larger capacity than ordinary batteries (lead-acid, etc.). Under the same weight, the capacity of a lithium iron phosphate battery is three times that of a lead-acid battery.

　　E: No memory effect

　　If the rechargeable battery is constantly working under the condition of being fully charged and not discharged, the capacity will quickly fall below the rated capacity value. This phenomenon is called the memory effect. Like nickel-metal hydride and nickel-cadmium batteries, there is memory, but lithium iron phosphate batteries do not have this phenomenon. No matter what state the battery is in, it can be charged and used without having to discharge it first.

　　F: Light weight

　　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.

　　G: Environmental protection

　　Lithium iron phosphate batteries are generally considered to be free of any 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.

　　However, some experts said that the environmental pollution caused by lead-acid batteries mainly occurred in the company's irregular production process and recycling process. The battery itself is a chemical substance, so there may be two kinds of pollution: one is the pollution of process excrement in the production engineering; the other is the pollution of the battery after it is scrapped.

　　H: High current can be discharged quickly

　　Lithium iron phosphate batteries can be charged and discharged quickly at a high current of 2C. Under a dedicated charger, the battery can be fully charged within 40 minutes of 1.5C charging, and the starting current can reach 2C. Lead-acid batteries do not have this performance now.

　　Lithium-ion battery (LIB) has become the main energy storage solution in modern social life. Among them, lithium iron phosphate batteries are a perfect substitute for lead-acid batteries, and are the first choice for grid-connected peak shaving, off-grid energy storage, photovoltaic energy storage, UPS, data center and other industries.

　　Solar power generation system with lithium battery energy storage system is a very promising clean energy.
