The electrode slice location structure of coating apparatus.
Background technique
Lithium battery is one kind by graphitic carbon material or other dusty material (such as metal oxide, sulfide, phosphides
Powder) as negative electrode material, use the battery of non-aqueous electrolytic solution.Lithium metal battery in 1912 is earliest by Gilbert N.
Lewis is proposed and is begun one's study.With the development of science and technology, the energy storage that present lithium battery has become mainstream is set
It is standby.
A large amount of researcher is just being engaged in the R&D work of lithium ion battery material in laboratory at present.In researcher couple
During the battery material developed is evaluated, being coated to lithium battery electrode plate is that lithium battery experimentation is important
One step, but the painting process in common laboratory is manual operations, be easy to cause and is unevenly coated, in irregular shape, size
The problems such as uncertain.During hardened coating, generally according to practical coating condition, it is round to find the uniform part progress of coating
Cutting, is then further dried heat treatment for the round pole piece after cutting, is finally made electrodes of lithium-ion batteries use, remaining
Part is abandoned as waste material.It generates the problem that in this way, is even coated with uniform part, due in irregular shape, i.e., can not
At rule circle, a large amount of unavailable leftover pieces can be also generated, wastage of material is caused.
Chinese patent (CN107096679A) discloses a kind of experiment lithium battery electrode sheet coating equipment, including digital display thousand divides
Ruler, crossbeam frame body, spreader, coating platform, pedestal, connecting rod, slide bar；It the advantage is that, be distributed using being coated in land regions
Vacuum suction area and the technology that is separated from each other of slurry applying area, avoid the substrate for being located at absorption hole site in coating process
Since the effect of negative pressure of vacuum generates recess, slurry thickness is caused to occur thickening phenomenon in the position, guarantees that slurry is entirely applying
The consistency of cloth area thickness, while platform is coated with using resistance heating, pole piece is toasted after coating to be avoided using Hot-blast Heating
Dry inconsistent phenomenon caused by drying.
