What does lithium iron phosphate battery mean

1、 Lithium iron phosphate battery.

Advantages. 1. Lithium iron phosphate batteries have a long lifespan, with a cycle life of over 2000 cycles. Under the same conditions, lithium iron phosphate batteries can be used for 7 to 8 years.

2. Safe to use. Lithium iron phosphate batteries have undergone strict safety testing and will not explode even in traffic accidents.
3. Fast charging. Using a dedicated charger, charging at 1.5C for 40 minutes can fully charge the battery.
4. Lithium iron phosphate batteries are resistant to high temperatures, and their hot air value can reach 350 to 500 degrees Celsius.
5. Lithium iron phosphate batteries have a large capacity.
6. Lithium iron phosphate batteries have no memory effect.
7. Lithium iron phosphate batteries are green, environmentally friendly, non-toxic, pollution-free, with a wide range of raw materials and low prices.

Disadvantages. 1. The compacted density of the positive electrode of lithium iron phosphate batteries is small, usually around 0.8 to 1.3. Large volume.

2. Poor conductivity, slow diffusion speed of lithium ions, and low actual specific capacity during high magnification charging and discharging.
3. The low-temperature performance of lithium iron phosphate batteries is poor.
4. The lifespan of a single lithium iron phosphate battery is long, around 2000 cycles, but the lifespan of a lithium iron phosphate battery pack is short, usually around 500 cycles.

Lithium batteries.

（1） Lithium batteries are a type of battery that uses lithium metal or lithium alloy as the negative electrode material and non aqueous electrolyte solution. Due to the highly reactive chemical properties of lithium metal, the processing, preservation, and use of lithium metal have high environmental requirements. So, lithium batteries have not been applied for a long time. With the development of science and technology, lithium batteries have now become the mainstream.

（2） Advantages.

1. The energy is relatively high. It has a high storage energy density, reaching 460-600Wh/kg, which is about 6-7 times that of lead-acid batteries.
2. Long service life, with a service life of over 6 years. The battery with lithium ferrous phosphate as the positive electrode is charged and discharged at 1C (100% DOD), with a record of being able to be used 10000 times.
3. High rated voltage (individual working voltage of 3.7V or 3.2V), approximately equal to the series voltage of three nickel cadmium or nickel hydrogen rechargeable batteries, making it easy to form a battery power pack; Lithium batteries can be adjusted to 3.0V through a new type of lithium battery voltage regulator technology, which is suitable for the use of small appliances.
4. Equipped with high power endurance, the lithium iron phosphate lithium-ion battery used in electric vehicles can reach a charging and discharging capacity of 15-30C, facilitating high-intensity starting acceleration.
5. The self discharge rate is very low, which is one of the most prominent advantages of this battery. It can generally achieve less than 1% per month, less than 1/20 of that of nickel hydrogen batteries.
6. Lightweight, with a weight of approximately 1/6-1/5 that of lead-acid products in the same volume.
7. It has strong adaptability to high and low temperatures and can be used in environments ranging from -20 ° C to -60 ° C. After processing, it can be used in environments ranging from -45 ° C.
