Problems solved by technology

However, only a small portion of the air heated by the heater is used to dry the active material, and the rest of the heated air is not used
In other words, the energy efficiency of the drying unit is low

Embodiment Construction

[0016] Hereinafter, embodiments will be described in detail with reference to the accompanying drawings.

[0017] figure 1 is a view showing the drying system according to the embodiment.

[0018] refer to figure 1 , the drying system 100 according to the embodiment includes a suction fan 110 , an air heating unit 120 , a drying unit 130 and a heat exchanging unit 140 . In addition, the drying system 100 may further include an exhaust fan 150 , a damper 160 , a concentration meter 170 , a pressure gauge 180 and a thermocouple 190 .

[0019] The suction fan 110 sucks air from the outside and supplies the air to the air heating unit 120 . The air heating unit 120 heats air, and supplies high-temperature air to the drying unit 130 . The air supplied to the drying unit 130 dries the electrode plate coated with the active material and disposed at the drying unit 130 . The air exhausted from the drying unit 130 is supplied into the heat exchanging unit 140 and exchanges heat wi...

Abstract

The invention provides a drying system which can increase the efficiency of the power for drying the electrode plate. The drying system comprises a suction fan which sucks the air from the outside, an air heating unit for heating up the air sucked by the suction fan, a drying unit which is used for receiving the air from the air heating unit for drying the electrode plate coated by the active material, and a heat exchange unit for exchanging the air discharged from the drying unit with the air sucked by the fan, wherein part of the discharged air from the drying unit returns to the entrance port of the air heating unit.

Description

technical field [0001] Embodiments relate to a drying system configured to dry an electrode plate coated with an active material. Background technique [0002] The lithium secondary battery may have the form of a battery pack. The battery pack includes: an electrode assembly including a positive electrode plate, a negative electrode plate, and a separator; a can configured to accommodate the electrode assembly; a bare cell including a cap assembly configured to seal an upper end of the can; a protection circuit module including a charging device and a discharge device; and a positive temperature coefficient (PTC) thermistor connected to each of the bare cell and the protection circuit module. When the internal temperature of the bare cell rises, the resistance of the PTC thermistor increases rapidly to interrupt the current flow. [0003] The positive electrode plate is formed by coating a positive electrode current collector with a positive electrode active material, and ...
