Abstract

Provided is an active material-coating apparatus for a secondary battery and methods of operating the same. The active material-coating apparatus includes a tank having an active material, a pump coupled to the tank such that the active material is routed through the pump, a temperature control unit coupled to the pump and configured to control heating or cooling of a temperature of the active material routed through the pump. The temperature control unit may include a control unit configured to control a temperature of the temperature control unit. The active material-coating apparatus may further include a coating unit coupled to the temperature control unit, and a reel including a current collector, the reel being configured to route the current collector through the coating unit such that the current collector is coated with the active material routed through the temperature control unit and ejected from the coating unit.

Description

[0001] Cross References to Related Applications [0002] This application claims priority and benefit from Korean Patent Application No. 10-2013-0071950 filed with the Korean Intellectual Property Office on June 21, 2013, the disclosure of which is hereby incorporated by reference in its entirety. technical field [0003] One or more embodiments of the invention relate to an active material coating device for a battery and a method of operating the same. Background technique [0004] Unlike primary batteries, which cannot be recharged, secondary batteries can be discharged and recharged. Secondary batteries are widely used as energy sources for mobile electronic devices such as digital cameras, cellular phones, and computers. [0005] In order to solve environmental problems, secondary batteries are also used as energy sources for hybrid electric vehicles as an alternative to conventional gasoline and diesel internal engines that use chemical fuels. In addition, secondary ...
