Comparison of advantages and disadvantages of lithium iron phosphate battery and lithium battery

Lithium Iron Phosphate Battery:

The lithium iron phosphate battery refers to a lithium-ion battery that uses lithium iron phosphate as the positive electrode material. The cathode materials of Li-ion batteries include lithium cobalt, lithium manganate, lithium nickel, ternary materials, lithium iron phosphate, and so on. Lithium cobaltate is the anode material used in most Li-ion batteries.

Advantages of Lithium Iron Phosphate Batteries:

1, Lithium Iron Phosphate battery life is long, cycle life of more than 2000 times. Under the same conditions, Li-ion Iron Phosphate batteries can be used for 7 to 8 years.

2, safe use. Lithium-Ion Iron Phosphate batteries have passed rigorous safety tests and will not explode even in traffic accidents.

3. Fast charging. Using a special charger, the 1.5C charge can be fully charged in 40 minutes.

4, Lithium Iron Phosphate battery pack high temperature resistance, Lithium Iron Phosphate battery hot air value can reach 350 to 500 degrees Celsius.

5, Lithium Iron Phosphate battery capacity is large.

6, Lithium Iron Phosphate battery has no memory effect.

7, lithium iron phosphate battery green environmental protection, non-toxic, pollution-free, wide source of raw materials, cheap.

Lithium-ion batteries:

Lithium-ion batteries are a class of batteries using lithium metal or lithium alloy as the negative electrode material and a non-aqueous electrolyte solution. Due to the very active chemical properties of lithium metal, the processing, conservation and use of lithium metal have very high environmental requirements. Therefore, lithium-ion batteries have not been used for a long time. With the development of science and technology, lithium-ion batteries have become mainstream.

Advantages of Li-ion Batteries:

1. High energy. It has a high storage energy density, which has reached 460-600Wh/kg, which is about 6-7 times that of lead-acid batteries.

2, long service life, service life can reach more than 6 years, lithium iron phosphate as the positive battery 1C charge and discharge, can be used 10,000 times records;

3, the rated voltage is high, the single working voltage is 3.7V or 3.2V, about equal to the series voltage of 3 nickel cadmium or nickel metal hydride batteries, easy to form a UPS power battery pack; lithium-ion batteries can be adjusted to 3.0V through a new type of lithium-ion battery regulator technology, which is suitable for the use of small electrical appliances;

4, with high power capacity, the lithium-ion iron-phosphate battery for electric vehicles can reach 15-30C charging and discharging capacity, which is convenient for high-strength starting acceleration;

5, the self-discharge rate is very low, which is one of the most prominent advantages of lithium-ion batteries, generally can be less than 1% / month, less than 1/20 of nickel-metal hydride batteries;

6, light weight, the weight of the same volume is about 1/6-1/5 of the lead-acid product;

7, high and low temperature adaptability, can be used in the environment of -20℃ -60℃, after process treatment, can be used in the environment of -45℃;

8, lithium-ion battery green environmental protection, regardless of production, use and scrap, do not contain, do not appear any lead, mercury, cadmium and other toxic and harmful heavy metal elements and substances.

9, the production basically does not consume water, for the shortage of water in our country, very advantageous.

The difference between lithium iron phosphate batteries and lithium-ion batteries:

1, iron phosphate lithium-ion battery pack is used to do lithium-ion secondary battery, now the important direction is the power Lithium Battery, relative to NI-H, Ni-Cd battery has a great advantage.

2, lithium-ion battery is a class of lithium metal or lithium alloy as the positive electrode material, the use of non-aqueous electrolyte solution of the battery. The chemical properties of lithium metal are very active, which makes the processing, conservation and use of lithium metal very high environmental requirements.

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