Description

Artificial plumbago negative pole material shaping char particle grading fully-automatic production system

Technical field

The utility model patent is related to a kind of fully-automatic production system, and in particular to artificial plumbago negative pole material shaping coke Grain grading fully-automatic production system.

Background technique

Lithium ion battery has the advantages that specific capacity height, operating voltage height, the good, memory-less effect of safety etc. are a series of, It is widely used in many portable electronic instrument equipment such as laptop, mobile phone and instrument and meter.With new energy Automobile is popularized, and application range has been extended to the fields such as electric vehicle, automobile.In recent years, with electronic product and vehicle-mounted and storage Miniaturization, lightweight and multi-functional, drivingization for a long time requirement is continuously improved in energy equipment, close to lithium ion battery high-energy The requirement of degreeization, high rate capability and long circulation life is also constantly being promoted.

Negative electrode material plays key effect as one of battery core component, to battery comprehensive performance.In existing cathode In material, artificial graphite due to have many advantages, such as with compatibility of electrolyte it is good, circulation and high rate performance it is good, become commercialized lithium Ion battery cathode material.But the capacity of artificial graphite is relatively low, it is caused to be restricted in the application of power battery.It is Chinese special Sharp CN103811758A and CN105304870A by small grain size artificial graphite presoma (petroleum coke, needle coke, pitch coke etc.) and Binder (pitch, coal tar) mixing can be viscous by petroleum coke of small grain size etc. under high temperature (600 DEG C~700 DEG C) stirring condition Secondary granulation is tied into the product of larger granularity.Compared with the product of one-size, which can effectively improve the capacity of artificial graphite And cycle performance.But in above-mentioned heating process, the material that some little particles are bonded to greater particle size will cause, these larger grains Diameter material will affect the performance of negative electrode material, be easy to lead to local defect in inside battery, final to reduce making for lithium ion battery Use the service life.So the material after secondary granulation all needs the particle for removing larger granularity by classification, the particle of these larger granularities Again granularity, which reaches requirement, after crushing to use.And traditional single machine classification and pulverizing process are respectively independent, a process is complete It needs hand haulage toward next work process after, causes workshop dust larger, environmental degradation, and raw material yield reduces, work The labor intensity of people is high, and working condition is poor, and complicated for operation, production efficiency is lower, and is easy in open material transportation process It brings impurity into, affects product quality.
