1、 Introduction of lithium iron phosphate roasting furnace:
1. It is suitable for the calcination of LiFePO4 cathode material for lithium ion battery.
2. The sintering of carbon supplying molecular sieves, catalysts water filtering static particles.
3. One furnace two tanks are strengthened alternately, which greatly reduces heat loss production cost.
4. The slow cooling box charging frame are randomly arranged to facilitate the rotation charging of the furnace during cooling down.
2、 Performance of lithium iron phosphate:
A. The theoretical specific capacity is 170 MAH / g the actual specific capacity of the product can exceed 140 MAH / g (0.2C, 25 ° C);
B. At present, lithium ion battery cathode materials;
C. It has no pollution does contain any harmful heavy metal elements to human body;
D. Long cycle life. Under DOD condition, it can charge discharge more than 2000 times;
E. There was no memory effect;
F. Fast charging performance, lithium iron phosphate cathode material of lithium battery, can use high rate charging, can be fully charged in 1 hour. The traditional cathode materials for lithium-ion batteries have been hindering the development application of power lithium-ion batteries due to their defects in price cycle performance.
1. Technical performance of lithium iron phosphate sintering furnace:
In terms of technical performance, the conventional static stack type calcination is adopted in the channel kiln. Due to the accumulation of materials, there are some characteristics in the calcination process, such as easy entrainment, long reaction time, volatile emission, high manual stacking strength of saggers, small relative output, low product quality uniformity, etc. for the rotary kiln, due to the new dynamic calcination method, the material The heat conduction speed is fast the calcination period is greatly shortened when the material is brought up turned continuously during operation. Volatile gas emission can be fast in dynamic calcination (rotary furnace).
2. Nitrogen consumption of LiFePO4: 0
In terms of nitrogen consumption, due to the good sealing performance of the rotary furnace, the nitrogen consumption is only 1-4m3 / h, the calcined material quality is particularly good, which can greatly save energy. However, the nitrogen consumption of similar products in the world is more than 15m3 / h. However, the sealing of the channel kiln is relatively traditional, the atmosphere protection naturally needs a large amount of nitrogen other inert gases for atmosphere protection It increases the cost does save energy.
3. Reliability of LiFePO4:
At present, there is no mature perfect precedent for vacuum rotary kiln in China. It is difficult to produce such a difficult equipment the perspective of technology manufacturing. If we want to achieve the same use index, there are some difficulties. The vacuum rotary furnace has been independently designed manufactured by our company, its performance has been recognized by many customers.
4. Economy of LiFePO4
Channel kiln must use a large number of vulnerable consumable parts, but rotary furnace does have these; in terms of the same output, the energy consumption index of the channel kiln is greater than that of the rotary furnace, the daily production cost can be saved by more than 30% compared with that of the rotary furnace, the rotary furnace has a greater advantage in operation cost. Once the production capacity of the channel kiln is determined, it will be difficult to make a large adjustment in the future. However, the production environment production means of the rotary kiln have more room for adjustment. For example, when the product process is improved updated, the burning cycle of the equipment will be adjusted to make the rotary kiln easier to realize. For the same product, the use of dynamic calcination can shorten the firing cycle increase the output accordingly.
5. Lithium iron phosphate has no pollution
Under the premise of vacuum sealing effect, the rotary furnace can realize the centralized emission of flue gas volatile products, can be connected to the water seal for centralized sewage treatment at the same time.
