Specifically, following effect may be implemented in above-mentioned steps:

1, the primary carbon coating of active material:

The pre- stirring of dry powder solves the uniform premix of powder, the primary carbon coating of active material.It is special using horizontal type device Different agitating paddle form also may be implemented to be thoroughly mixed within 10min even if powder and powder ratio are especially big；

2, it is kneaded:

The work technique sheet of above step, so that the dry powder after premix becomes pureed rubbing under suitable glue ratio Operating condition；

3, profit is invaded in depolymerization:

Purpose is the particle dismantling of reunion to open, particle surface modification, it may be assumed that the interface of active matter modifies.Active material After sintering, generally all it is difficult to infiltrate, and surface has a lot irregularly containing the micropore of gas, modified purpose is exactly to allow Grain sufficiently infiltration, excludes gas, improves surface tension；

4, it coats:

Uniform, the firm cladding of the auxiliary materials such as conductive agent and active material；

5, scientific linear velocity and adhesion technique:

Above equipment will not destroy the physical structure of particle at runtime；

As shown in figure 9, wherein slurry shiny appearance is moist, stream for the slurry pole piece after the refining system stirring of the application Dynamic property is good, and solid content, fineness, viscosity are superior to the slurry after equipment stirring in the prior art, thus proves the present embodiment The good slurry of consistency can be continuously made in the homogenization system of offer in a short time, and easy to operate, and labor intensity is low, throw Material cleaning eliminates cleaning tank body and scrapes the trouble of paddle, avoids the problem of humid air influences stock quality, and equipment accounts for Ground area is small, and treating capacity is big, and operator is few, is the excellent equipment of high-volume high quality slurrying.

As shown in Figure 10, the pole piece for the slurry made for traditional blender, since there is following defects for traditional blender:

1, formula rate is easily lacked of proper care, slurry water suction is denaturalized:

Traditional blender is the lifting of upper lower barrel body, closed type mixed form, and the drive mechanisms such as agitating paddle are deep from upper barrel body Enter to lower barrel body and drives material stirring.In this way, slurry is easy to be splashed on upper barrel body and transmission parts in stirring, powder and slurry Material becomes dead material, and slurry is contacted with air after staving decline, and slurry after water suction is caused to be denaturalized；

2, the consistency of slurry hardly results in guarantee:

Since traditional blender causes revolving speed permanent by belt and chain drive with the stretching of belt and chain It is fixed, in addition the splashing of slurry, cause the slurry worked it out in every proportion imbalance such as solid content, viscosity, slurry batch it is consistent Property is seriously out of control；

3, the fineness of slurry is difficult to control:

Since there is very wide arc gap at the agitating paddle of traditional blender and bucket wall, bucket bottom, it is easy to produce dead material and incomplete mixing.Separately Outside, be splashed to agitator top slurry mix at all less than.Therefore, the fineness of slurry is typically all two multiples of supplied materials particle It is more than value；

4, failure rate is higher:

Since complicated transmission parts are above slurry stirring barrel, when stirring slurry, slurry, which splashes, easily enters bearing, cleaning When liquid also can enter bearing, cause damage high failure rate.In addition, the blender of many factory's productions, there are also greases to drain to slurry In harm；

5, it is unable to continuous slurrying and cleaning is inconvenient:

Traditional blender can only the slurrying of one tank of tank ground, and clean one secondary eight more than hour；

Due to the influence of the factors such as device structure, common people can not made of traditional blender the slurry got well come；

Therefore, from the point of view of the comparison of pole piece, the refining system of the application compares the slurry effect that traditional mixing plant is made More preferably.

As shown in FIG. 11 and 12, the pole piece for the slurry made for double screw extruder, due to double screw extruder there is Following defect:

1, the homogeneity of slurry is too poor:

Due to incorporation time wretched insufficiency, active material cannot be completely by liquid immersion, depolymerization, and the consistency of slurry is poor, The especially Ketjen black material that everybody adds now in order to improve the electric conductivity of battery；

2, conductive agent is reunited serious:

Due to the short problem of incorporation time, active material cannot be coated by conductive agent class material, caused conductive agent to reunite, led Cycle-index and the energy density for sending a telegraph pond are not high enough.

Even if subsequent technique uses high speed disperser, it is also difficult to obtain well dispersed slurry, result even in and " roll into a ball again It is poly- " the phenomenon that；

3, batch production, waste are unable to seriously:

Twin-screw can only continuously continuously run production, every to shut down, be switched on once, will cause front and back end and generate because adjusting operating The waste of many slurries, and last time is trapped in the slurry in screw rod and can only also scrap；

6, not easy cleaning:

If replacing material system it is necessary to thoroughly clean screw rod inner cavity.Since entire screw rod fuselage is disassembled, generally need Take two days or more time；

As shown in figure 12, pole piece has conductive agent to reunite (circled in figure), and inside this bulge agglomerated into It is the conductive agent powder not infiltrated.

Therefore, from the point of view of the comparison of pole piece, the refining system of the application compares the slurry effect that traditional mixing plant is made More preferably.
