Abstract:
1. A coating machine for manufacturing a battery including a positive electrode having a positive collector layer and a first plurality of mixture layers formed on the positive collector layer, a negative electrode having a negative collector layer and a second plurality of mixture layers formed on the negative collector layer, and an electrolyte layer, the coating machine comprising: a nozzle for delivering coating materials; a conveying means system effective to position a body-to-be-coated opposite to the nozzle, the body-to-be-coated being a next mixture layer from one of the first plurality of mixture layers and the second plurality of mixture layers; a pressurization means for placing the coating materials on the body-to-be-coated under pressure; a closing means for selectively closing a flow path of the coating materials inside the nozzle; a control means for operating said closing means and said pressurization means in a manner to intermittently deliver the coating materials from the nozzle; and a sensor effectively detecting a position of the body-to-be-coated while it is conveyed and transmitting a sensor signal to the control means for operating said closing means and said pressurization means, wherein said conveying means system is operatively configured to control a thickness of said electrolyte layer formed from said coating materials on said body-to-be-coated by adjusting a distance between said conveying means system and the nozzle.
