The positive electrode in lithium-ion batteries is made of lithium iron phosphate. It offers many advantages in terms of security and longevity. They are among the most significant indicators of the power battery’s technical performance. Lifepo4 batteries with one-C charge and discharge cycles longevity can last for 2000 times. The puncture is not exploding It is not easy to explode and burn when charged too high. Lithium iron phosphate cathode material enable large-capacity lithium-ion battery to utilize in series.
Lithium iron phosphate is a cathode material
Lifepo4 battery refers specifically to the lithium-ion batteries that use lithium iron phosphate as the negative electrode. The positive electrodes of lithium-ion batteries mostly comprise lithium manganate, lithium cobaltate lithium nickelate, secondary substances including lithium iron phosphate and similar. Of these lithium cobaltate, it is the material used for positive electrodes utilized in the majority of lithium-ion battery. In theory lithium iron phosphate can also an embedding process and deintercalation. This is the same principle as lithium manganate and lithium cobaltate.
Lifepo4 battery benefits
1. High efficiency in charging and discharging
Lifepo4 battery can be described as a lithium-ion second battery. The primary purpose of this battery is to power batteries. Lifepo4 has many advantages over Ni-Cd and NI-MH batteries. Lifepo4 battery is high in discharge and charge effectiveness, and its capacity of discharge and charge can be as high as 90% under the conditions of discharge in contrast, the lead-acid battery has approximately 80 percent.
2. Lifepo4 battery with high safety performance
The P-O bond found in the crystal of lithium iron phosphate is strong and hard to break down. It isn’t prone to bursting or heating as a cobaltate lithium crystal or make an oxidizing material that is strong even at high temperatures or overcharge. This means it is safe.
There is a report that during the actual test there was a small portion of the sample was discovered to exhibit a burning effect in the short-circuit or acupuncture test, however it was not an explosion. In the experiment of overcharge using a high-voltage charge which was many times greater than the self-discharge voltage utilized to determine that there was a Explosion phenomena. But, its safety in overcharge has been significantly enhanced compared to the standard lithium cobalt-based liquid electrolyte battery.
3. Lifepo4 battery life long cycle
A Lifepo4 battery refers specifically to the lithium-ion battery that uses lithium iron phosphate for a positive electrode. Long-life lead-acid batteries have an average cycle time of 300 times. The maximum number is 500. Lithium iron phosphate battery has a life span of more than 2000 times and the normal charges (5-hour rate) is able to be used for up at 2000. The same high-quality lead-acid battery can be described as “new half-year, old half year maintenance as well as maintenance over a half-year” and lasts for with a lifespan of 1~1.5 years. If when the lifepo4 battery is utilized in the same way The theoretical lifespan can be extended to 78 years. When you look at it all in detail the price/performance ratio is more than four times higher than lead-acid batteries. High-current discharge is able to be swiftly charged and discharged using 2C high-current. With the specially designed charger, the battery is fully charged in 1.5 minutes after 1.5C charging. Additionally, the beginning current can be as high as 2C. However, the lead acid battery does not have this capability.
4. Good temperature performance
The maximum temperature of lithium iron phosphate could reach 350 deg C 500 deg C however lithium manganate and lithium cobaltate range just 200 degrees C. A wide operational temperature band (-20C–+75C) With high-temperature resistance, the lithium iron phosphate electrical heating peak can be as high as 350 degC to 500 degC, whereas lithium manganate as well as lithium cobalt oxide only have a temperature of 200 degrees Celsius.
5. Lifepo4 battery with high capacity
It has a higher capacity than conventional batteries (lead-acid or lead-acid, etc.). The monomer’s capacity ranges from 5AH to 1000AH.
6. No memory impact
Batteries that are rechargeable operate in environments that are typically not fully discharged and their capacity can quickly drop below the capacity of the battery. This is known as”the memory effect. Memory is similar to nickel-metal Hydride and nickel-cadmium batteries. But the lifepo4 battery doesn’t exhibit this effect, regardless of what condition that the battery may be in. It will be used while charging and there is no requirement to recharge and discharge.
7. Lightweight of the lifepo4 battery
The lifepo4 batteries of similar capacity to the one described above is 2/3 the size of the lead-acid batteries, and weighs 1/3 of that of the lead-acid batteries.
8. Lifepo4 batteries are eco-friendly.
The battery is typically thought as free from rare metals or heavy metallics (Ni-MH battery requires rare metals) Non-toxic (SGS certified) as well as non-polluting. In conformity in line with European RoHS regulations, is an absolutely green battery certification. The reason for why lithium batteries are highly regarded by the industry is mostly environmental concerns. This is why the battery was integrated into the “863” national high-tech development plan for the “Tenth Five-Year Plan” period , and is now a the nation’s key support and development program. As China joins the WTO and the increase in exports of electronic bicycles from China will grow rapidly and electric bicycles coming into Europe or those entering the United States have been required to be fitted with non-polluting batteries. The performance of a lithium-ion battery is largely dependent on the negative and positive materials. The Lithium Iron Phosphate (LIP) is one of the lithium battery material that only been discovered in the last few years. The safety and life span are unmatched with other battery materials. The most significant indicator of the technical characteristics of the batteries. Lifepo4 batteries have the advantages of being non-toxic and non-polluting. It also has excellent safety, a large variety of raw materials, affordable prices, and a longevity. It is the ideal cathode material to be used in the new version of batteries made from lithium.
