Abstract
A system for drying an electrode includes: an oven which applies hot air and radiant heat to an electrode sheet; and a controller which receives information on drying standby time, and controls an amount of heat supplied into the oven. Herein, the controller controls to supply a reduced amount of heat to the oven during an initial drying time right after the supply of the electrode sheet after the drying standby time.
Claims15
A system for drying an electrode, the system comprising:
- an oven which applies hot air and radiant heat to an electrode sheet;
- and
- a controller which receives information on drying standby time when a supply of the electrode sheet into the oven is stopped, wherein the controller determines and controls an amount of heat supplied into the oven according to a length of the drying standby time, and
- wherein the controller controls to supply a reduced amount of heat than a general supply amount of heat (Qt) to the oven during an initial drying time right after the supply of the electrode sheet after the drying standby time.

A method of drying an electrode sheet, the method comprising:
- (a) a process of collecting information on drying standby time which is a time interval when a supply of the electrode sheet into an oven for drying the electrode sheet is stopped;
- (b) a process of determining a condition on an amount of heat to be supplied into the oven when the electrode sheet is supplied into the oven after the drying standby time;
- and
- (c) a process of supplying the electrode sheet into the oven after the drying standby time and drying the electrode sheet at the condition on the amount of heat determined during the process (b),
- wherein the process (b) includes determining the condition on the amount of heat to supply a reduced amount of heat than a general supply amount of heat (Qt) to the oven during an initial drying time.
