The positive electrode in lithium-ion batteries is made of lithium iron phosphate. It provides a number of advantages for security and longevity. They are among the most crucial technological indicators of a power battery. Lifepo4 batteries with one-C charge and discharge cycles is able to last 2000 times. The puncture doesn’t explode It is not easy to ignite and cause explosions when it is overcharged. The cathode materials made of lithium iron phosphate allow large capacity lithium-ion batteries to work with in series.
Lithium iron-phosphate cathode material
Lifepo4 battery refers specifically to an lithium-ion battery that uses lithium iron phosphate as the positively charged electrode. The positive electrode materials in lithium-ion batteries typically include lithium manganate, lithium cobaltate lithium nickelate, secondary substances including lithium iron phosphate and similar. In the group 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 and deintercalation procedure. This is the same principle as lithium manganate and lithium cobaltate.
Lifepo4 battery benefits
1. High charge and discharging efficiency and high charging efficiency
Lifepo4 battery is lithium-ion second battery. Its primary function is to power batteries. It offers many advantages over Ni-Cd and NI-MH batteries. Lifepo4 battery is high in capacity and discharge effectiveness, and its capacity of discharge and charge can exceed 90% in the conditions of discharge when the lead-acid batteries are around 80 percent.
2. Lifepo4 battery high security 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 like lithium cobaltate, or make an extremely oxidizing compound even at high temperatures or overcharge. It is of high safety.
There is a report that during the actual test the small percentage of the test sample was observed to be experiencing a burning sensation during the acupuncture or short-circuit 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 potential was utilized and it was discovered that there was an Explosion phenomena. But, its safety in overcharge has been significantly enhanced compared to the conventional lithium cobalt oxide liquid electrolyte battery.
3. Lifepo4 battery with long cycle life
Lifepo4 battery refers specifically to an lithium-ion-based battery which uses lithium iron phosphate for a positive electrode. Long-life lead-acid batteries have the capacity to cycle for around 300 times. The most powerful amount is around 500. Lithium iron phosphate power batteries is able to cycle for more than 2000 times and the normal charging rate (5-hour rate) is able to be used for up around 2000 times. The same lead-acid battery has “new half-year, older half-year maintenance as well as maintenance over a half-year” and lasts for that is up to 1~1.5 years. If the Lifepo4 battery can be used 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 the price of lead-acid batteries. High-current discharges can be rapidly charged and discharged using high-current 2C. With the specially designed charger, the battery will be fully charged in 1.5 minutes after 1.5C charging. The initial current can reach 2C. However, the lead acid battery does not have this capability.
4. Good temperature performance
The temperature at which lithium iron phosphate is 350 deg C 500 deg C in comparison to lithium manganate and lithium cobaltate range at a lower temperature of around 200 deg C. A wide operational temperature band (-20C–+75C) and high temperature resistance, lithium ironphosphate electric heating peak could reach 350 degC-500 degC. lithium manganate and lithium cobalt oxide are only have a temperature of 200 degrees Celsius.
5. Lifepo4 battery with high capacity
It is larger than normal batteries (lead-acid or lead-acid, etc.). The monomer’s capacity is 5AH to 1000AH.
6. No memory impact
Batteries that are rechargeable operate in conditions that are usually not fully discharged and capacity will rapidly decrease to below the capacity that is rated. This is known as”the memory effect. Memory, like nickel-metal-hydride and nickel-cadmium batteries. But the lifepo4 batteries do not suffer from this issue, and regardless of what condition its battery has reached, it is able to be used while charging without the requirement to recharge and discharge.
7. Lightweight lifepo4 battery
The lifepo4 batteries of the same capacity has 1/3 of the size of the lead-acid battery and weighs 1/3 of the lead-acid battery.
8. Lifepo4 batteries are non-toxic.
The battery is typically thought as free from rare or heavy metallics (Ni-MH batteries need rare metals) and 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 ecological considerations. So, the battery was added to the “863” national high-tech development program during the “Tenth Five-Year Plan” time frame and is now a the national primary support and development program. Since China’s accession to WTO in the year 2000, the volume of 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. It is one of the lithium battery material that only recently been introduced. Its safety characteristics 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 performance, a broad selection of raw materials affordable prices, and a longevity. It is a great cathode material to be used in the new battery made of lithium-ion.
