3. Charging fast. With a dedicated charger, the battery can be fully charged by charging at 1.5C for 40 minutes.

4. The lithium iron phosphate battery is resistant to high temperature, and the hot air value of the lithium iron phosphate battery can reach 350 to 500 degrees Celsius.

5. The capacity of lithium iron phosphate battery is large.

6. Lithium iron phosphate battery has no memory effect.

7. Lithium iron phosphate battery is environmentally friendly, non-toxic, non-polluting, with a wide range of raw materials and low prices.

Disadvantages of lithium iron phosphate battery

1. The tap density of the positive electrode of lithium iron phosphate battery is small, and the density is generally about 0.8 to 1.3.

2. The conductivity is poor, the diffusion speed of lithium ions is slow, and the actual specific capacity is low when charging and discharging at high times.

3. The low-temperature performance of lithium iron phosphate battery is poor.

4. The life of a single battery of lithium iron phosphate battery is about 2,000 times, but the life of lithium iron phosphate battery pack is short, generally about 500 times.

Introduction to lithium battery

A lithium battery is a type of battery using a lithium metal or a lithium alloy as a negative electrode material and using a nonaqueous electrolyte solution. Due to the very active chemical properties of lithium metal, the processing, storage, and use of lithium metal are very demanding on the environment. Therefore, lithium batteries have not been used for a long time. With the development of science and technology, lithium batteries have become the mainstream.

Advantages of lithium batteries

1. The energy is relatively high. With high storage energy density, it has reached 460-600Wh/kg, which is about 6-7 times that of lead-acid batteries;

2. Long service life, the service life can reach more than 6 years, lithium iron phosphate is the positive battery 1C (100% DOD) charge and discharge, there are records that can be used 10,000 times;

3. The rated voltage is high (the single working voltage is 3.7V or 3.2V), which is equal to the series voltage of 3 nickel-cadmium or nickel-hydrogen rechargeable batteries, which is convenient to form the battery power pack; the lithium battery can be adjusted by a new type of lithium battery. The technology of the press, the voltage is adjusted to 3.0V, suitable for the use of small appliances;

4. With high power bearing capacity, which lithium iron phosphate lithium ion battery for electric vehicles can achieve 15-30C charge and discharge capacity, easy to start high-intensity acceleration;

5. The self-discharge rate is very low, which is one of the most outstanding advantages of the battery, generally can be 1% / month or less, less than 1 / 20 of the nickel-hydrogen battery;

6. Light weight, the weight of the same volume is about 1/6-1/5 of lead-acid products;

7. High temperature and low adaptability, can be used in the environment of -20 ° C -60 ° C, after the process of processing, can be used in -45 ° C environment;

8. Green and environmental protection, no matter whether it is produced, used or scrapped it does not contain any toxic and harmful heavy metal elements and substances such as lead, mercury and cadmium.

9. Production basically does not consume water, which is very beneficial for China that lacks water. Specific energy refers to the energy per unit weight or unit volume. The specific energy is expressed by WH/kg or WH/L. WH is the unit of energy, W is watt, h is hour; kg is kilogram (weight unit), and L is liter (volume unit).

Disadvantages of lithium batteries

1. Lithium primary batteries have poor safety and there is a danger of explosion.

2. The lithium ion battery of lithium cobalt oxide cannot discharge at a large current, and the price is expensive and the safety is poor.

3, lithium-ion batteries need to protect the line to prevent the battery from being overcharged and discharged.

4. High production requirements and high cost.

5, the use of conditions are limited, high and low-temperature use is dangerous.

Lithium battery application field

First, the traffic power supply

Second, the power storage power supply

Third, mobile communication power

Fourth, new energy storage power

Fifth, Aerospace military power supply

The difference between lithium iron phosphate battery and lithium battery

Lithium iron phosphate batteries are not the same as lithium batteries.

1. Lithium iron phosphate battery is used for lithium ion secondary battery. Now the main direction is power battery. Compared with NI-H, Ni-Cd battery has great advantages.

2. A lithium battery is a type of battery that uses a lithium metal or a lithium alloy as a positive electrode material and uses a nonaqueous electrolyte solution. The chemical properties of lithium metal are very active, making lithium metal processing, storage, and use very demanding on the environment.

3, lithium iron phosphate puncture does not fire does not explode, lithium battery will.

4, lithium iron phosphate resistant to overcharge to 100% will not cause fire and explosion; lithium battery reaches the specified value will be gassing bulging.
