Nano sand mill application: lithium iron phosphate process

Lithium iron phosphate is a new type of electrode material for lithium-ion batteries.

The main application areas are:

1. Energy storage equipment

Energy storage equipment for solar and wind power generation systems, uninterruptible power system UPS, and use with solar cells as energy storage equipment;

2. Power tools

High-power electric tools (wireless), electric drills, weeders, etc.;

3. Electric vehicles

Electric motorcycles, electric bicycles, recreational vehicles, golf carts, electric lift trucks, cleaning vehicles, hybrid vehicles;

4. Small equipment

Medical equipment: (electric wheelchair, electric scooter), toys (remote control electric plane, car, boat);

5. Other small electrical appliances

Miner’s lamp, implantable medical device;

Because lithium iron phosphate has the characteristics of large discharge capacity, low price, non-toxicity, and no environmental pollution, it has been highly valued in the support of new energy vehicle fuel cells. The ternary lithium battery is currently the two most widely circulated batteries in the power battery market, and it is also the most widely used mainstream power source for electric vehicles.

The synthetic methods of lithium iron phosphate are:
Solid phase synthesis

1.1 High-temperature solid-phase reaction method: The most commonly used and most mature synthesis method at this stage. The nitrogen-protected pusher furnace, mesh belt furnace and rotary furnace are used for sintering.

1.2 Carbothermal reduction method (CTR): The synthesis method is simple, easy to operate, low raw material prices, and suitable for large-scale production.

1.3 Microwave synthesis method: short synthesis time, low energy consumption, suitable for laboratory research.

1.4 Mechanical alloying method

Liquid phase synthesis

2.1 Liquid phase co-precipitation method

2.2 Sol-gel method

2.3 Hydrothermal synthesis method

Other synthetic methods

Spark plasma sintering technology, spray thermal decomposition technology and pulsed laser deposition technology are also used in the synthesis of lithium iron phosphate.

In the production and preparation process of power batteries, raw materials need to be ground to the production of battery slurry. For lithium iron phosphate material process solutions and material modification and upgrading, please consult in detail.
