The invention relates to the technical field of lithium battery production, in particular to a drying system and a drying method.The drying system comprises a drying production line provided with an air supply outlet and an air exhaust outlet; the heat pump mechanism is provided with an evaporation side and a condensation side; the sensible heat exchanger is provided with a first channel and a second channel; the first end of the first channel communicates with outside fresh air, the second end of the first channel is connected with the air supply outlet, and the fresh air exchanges heat with the condensation side in the air supply process; the first end of the second channel is communicated with the evaporation side, and the second end of the second channel is communicated with the exhaust outlet. According to the embodiment of the invention, the condensation side of the heat pump mechanism is adopted for heat exchange, the energy efficiency ratio is obviously higher, meanwhile, after the sensible heat exchanger is adopted, heat of exhausted air can be further recycled, and therefore energy consumption can be reduced. And meanwhile, the heat of the exhaust air can preheat the fresh air, so that the energy consumption can be further reduced, and the energy utilization rate is improved.
