1、 What does LFP battery mean?

LFP battery is the abbreviation of LiFePO4. Its Chinese name should be called lithium iron phosphate, which is called lithium iron phosphate battery in full, with olivine structure. Lithium iron phosphate (molecular formula LiFePO4, also known as lithium iron phosphate, lithium iron phosphate, or LFP for short) is a cathode material for lithium ion batteries, also known as lithium iron phosphate batteries.

The unique feature is that it does not contain cobalt and other valuable elements, the price of raw materials is low, and the resources of phosphorus, lithium and iron are abundant on the earth, so there will be no supply problem. It has moderate working voltage (3.2V), large capacitance (170mAh/g), high discharge power, fast charging, long cycle life, and high thermal stability under high temperature and high heat environment.

This new material, which looks unknown but leads to the lithium battery revolution, is one of the structural classifications of olivine. The scientific name in mineralogy is triphyllite, which comes from the roots of the Greek word Tri and fylon. ...
... The color in the ore can be gray, brown or black.

During charging, part of lithium ions in lithium iron phosphate are removed, transferred to the negative electrode through the electrolyte, and embedded in the carbon material of the negative electrode. At the same time, electrons are released from the positive electrode and reach the negative electrode from the external circuit to maintain the balance of chemical reaction. In the discharge process, the lithium ion self negative pole comes out and reaches the positive pole through the electrolyte. At the same time, the negative pole releases electrons and reaches the positive pole from the external circuit to provide energy for the outside world.

2、 What are the characteristics of LFP battery?

LFP battery has the advantages of high working voltage, high energy density, long cycle life, good safety performance, low self discharge rate, and no memory effect. greep lfp battery has the following characteristics.

①High temperature discharge has better temperature stability and resistance, and the operating temperature range is - 20 ℃ to 70 ℃.
②Ultra thin characteristics, light weight, flexible size, flexible shape, and can adapt to a variety of applications.
③LFP battery has higher performance in power, discharge and life cycle by using lamination production process.
④Good safety performance, high cycle life, 2000+cycles.
⑤It can realize 150C pulse discharge, 90C discharge for 2 seconds, 45C continuous discharge and 5C fast charging voltage.
⑥The voltage, shape and capacity can be customized as required, and the thickness can reach 0.5mm.

3、 In which fields are LFP batteries mainly used?

Both LFP batteries and lithium batteries are green and environment-friendly, but the biggest difference between them is that LFP batteries have no safety factors such as overheating or explosion. In addition, the battery cycle life is about 4 to 5 times that of lithium batteries, which is 8 to 10 times higher than that of lithium batteries with high discharge power (large current can be generated instantaneously). In addition, the overall weight under the same energy density is about 30 to 50% less than that of lithium batteries. Therefore, LFP batteries are widely used. LFP batteries are mainly used in the following fields.

①UAV, remote control model (such as vehicle model, aircraft model, etc.);
②Intelligent wearable device;
③Starting power supply, portable power supply.
④Small medical instruments and portable instruments;
⑤Energy storage equipment for solar and wind power generation;
⑥UPS and emergency light, warning light and miner's lamp (with the best safety);
⑦Replace the 3V disposable lithium battery and nickel cadmium or nickel hydrogen rechargeable battery in the camera (with identical size);
⑧Electric tools: electric drill, electric saw, lawn mower, etc;
⑨Light electric vehicles: electric bicycles, golf carts, small flat battery cars, forklifts, cleaning vehicles, electric wheelchairs, etc;
⑩Large electric vehicles: buses, electric vehicles, sightseeing buses and hybrid vehicles.
