<table 1 >
Reference table 1 as shown in the coated test result, can be found out the variation along with the length of the second inclined plane 137b, the variation of thickness takes place applying edge.That is to say, when carrying out coating processes under the state that is set to 5mm or littler distance in the horizontal range c of the second inclined plane 137b and among the vertical range d each, applying edge increase sharply (soaring).That is to say that the coating edge of surge is that the position of 5mm falls gradually from each of the horizontal range c of the second inclined plane 137b and vertical range d.In addition, when carrying out coating processes under the state that is set to 5mm or bigger distance in the horizontal range c of the second inclined plane 137b and among the vertical range d each, increase gradually in the whereabouts (sinking) that applies the edge.Thereby the horizontal range c of the second inclined plane 137b and vertical range d are effective up to 7mm.Here, validity (effectiveness) can be illustrated in and apply the approaching whole coating thickness of thickness that the state that does not increase sharply along thickness direction at the edge applies the edge down.
Thereby, when the horizontal range b of the first inclined plane 137a is the horizontal range c of the 11.7mm and the second inclined plane 137b and among the vertical range d each when being 5mm, can find out in the surge that applies the edge to minimize.Here, first tiltangle of the first inclined plane 137a
1Can be set to 9 degree.
Below table 2 shown at the second inclined plane 137b and be set under the state of size of 5mm according to existing and the The coating experiment result who does not have the second inclined plane 137b of sphering.
<table 2 >
Reference table 2 is when the second inclined plane 137b tilts with straight shape and during not by sphering, can find out that second inclined plane of sphering is influential to the surge that applies the edge.Thereby, can find out that when being compared by the structure of sphering with the inclined plane of tap, the second inclined plane 137b that tilts with straight shape according to embodiment minimizes the surge that applies the edge.
Because the factor such as structure, angle and length has been optimized on the inclined plane that is arranged on two inner surfaces 137 of tap 133, can minimize so apply the surge at edge.Thereby, can be according to the slurry bringing device 100 of embodiment with uniform width and thickness coating active material 11 on current-collector 10.
Fig. 6 illustrates the flow chart that is used to make the method for slurry bringing device according to embodiment.That is to say that Fig. 6 is the flow chart of manufacturing approach that is used for the slurry bringing device 100 of key-drawing 1 to Fig. 5.In the following description, identical parts and assembly will by with Fig. 1 to Fig. 5 in those identical Reference numerals represent.In addition, because in above its details that discloses, so will omit its detailed description.
