1. Super long life
The cycle life of a long-life lead-acid battery is about 300 times, the highest is 500 times, while the cycle life of a lithium iron phosphate power battery is more than 2000 times, and the standard charge (5-hour rate) use can reach 2000 times. Lead-acid batteries of the same quality are "new half a year, half a year old, and half a year for maintenance", which is only 1 to 1.5 years at most, while lithium iron phosphate batteries will reach 7 to 8 years when used under the same conditions. Comprehensive consideration, the performance-price ratio will be more than 4 times that of lead-acid batteries.
2. Safe to use
Lithium iron phosphate completely solves the safety hazards of lithium cobalt oxide and lithium manganate. Lithium cobalt oxide and lithium manganate will explode in a strong collision, which poses a threat to the life and safety of consumers, while lithium iron phosphate has undergone strict The safety test will not produce an explosion even in the worst traffic accidents.
High current 2C can be quickly charged and discharged. With 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.
3. High-temperature resistance
The peak value of lithium iron phosphate electric heating can reach 350 ℃-500 ℃, while lithium manganese oxide and lithium cobalt oxide 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 cobalt oxide are only around 200 ℃.
4. Capacity
It has a larger capacity than ordinary batteries (lead-acid, etc.). Rechargeable batteries work under conditions that are often fully charged and not discharged, and their capacity will quickly fall below the rated capacity. 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.
The volume of a lithium iron phosphate battery of the same specification and capacity is 2/3 of the volume of a lead-acid battery and its weight is 1/3 of that of a lead-acid battery. The battery does not contain any heavy metals and rare metals (nickel-metal hydride batteries require rare metals), non-toxic (SGS certification), no pollution, in line with European RoHS regulations, is an absolute green battery certificate.
5. No memory effect
The performance of lithium power batteries mainly depends on the positive and negative materials. Lithium iron phosphate has only appeared in recent years as a lithium battery material. The domestic development of large-capacity lithium iron phosphate batteries was in July 2005. Its safety performance and cycle life are unmatched by other materials, and these are also the most important technical indicators of power batteries. 1C charging and discharging cycle life is up to 2000 times. Single-cell battery will not burn or explode when overcharged at 30V. Lithium iron phosphate cathode materials make large-capacity lithium batteries easier to use in series. To meet the needs of frequent charging and discharging of electric vehicles. It has the advantages of non-toxic, non-polluting, good safety performance, wide source of raw materials, low price and long life. It is an ideal cathode material for a new generation of lithium batteries.
The positive electrode of the lithium battery is lithium iron phosphate material. This new material is not the previous lithium battery cathode material LiCoO2; LiMn2O4; LiNiMO2. Its safety performance and cycle life are unmatched by other materials, and these are also the most important technical indicators of power batteries. The 1C charge-discharge cycle life is up to 2000 times. Single-cell battery will not burn or explode if the overcharge voltage is 30V. Piercing does not explode. Lithium iron phosphate cathode material makes it easier to connect in series to make large-capacity lithium batteries.
Lithium iron phosphate batteries also have their disadvantages: for example, the tap density of lithium iron phosphate cathode materials is small, and the volume of lithium iron phosphate batteries of equal capacity is larger than lithium batteries such as lithium cobalt oxide, so it does not have an advantage in miniature batteries.
