Optionally, the second body 15 is detachably connected with the first body 14 to facilitate replacement of the drying unit 40.

It should be noted that when the drying unit 40 includes the drying material, the time for replacing the drying unit 40 is different according to the drying material of different material, and the specific time can be determined by referring to the water absorption condition of the corresponding drying material in the prior art.

According to some embodiments of the present application, the first valve 20 and the third valve 90 are both waterproof and gas permeable valves.

The waterproof ventilation valve is a valve used for allowing air to pass through and blocking water to pass through, and comprises a waterproof ventilation film which has a certain blocking effect on water. The waterproof breathable film can be made of polytetrafluoroethylene.

The first valve 20 and the third valve 90 are both waterproof and air-permeable valves, which further reduce the humidity of the air entering the first containing chamber 11.

According to some embodiments of the present application, there is also provided an electric device, which includes the battery 100 according to any of the above aspects, and the battery 100 is used for providing electric energy for the electric device.

The powered device may be any of the aforementioned devices or systems that employ battery 100.

According to some embodiments of the present application, referring to fig. 3 and 4, the present application provides a battery 100, the battery 100 including a case 10, a first valve 20, a battery cell 30, a drying unit 40, a third valve 90, a temperature sensor 50, and a humidity sensor 60. The inside of box 10 is provided with partition portion 13, and partition portion 13 is for first chamber 11 and the second chamber 12 that holds with the inner space partition of box 10, and battery monomer 30 sets up in first chamber 11 that holds, and drying unit 40 sets up in the second chamber 12 that holds. The first valve 20 is disposed on a wall portion of the box body 10 to communicate the second accommodating chamber 12 with the outside of the box body 10, and air outside the box body 10 enters the first accommodating chamber 11 through the first valve 20 and the second accommodating chamber 12 in sequence. The third valve 90 is provided in the partition portion 13, and the third valve 90 communicates the first accommodating chamber 11 and the second accommodating chamber 12. The drying unit 40 serves to dry the air located in the second receiving chamber 12 so that the dried air enters the first receiving chamber 11. The pressure of the first accommodating chamber 11 and the pressure of the second accommodating chamber 12 are both the pressure outside the tank 10. The air humidity of the first accommodating chamber 11 is less than the air humidity of the second accommodating chamber 12, and the air humidity of the second accommodating chamber 12 is less than the air humidity outside the cabinet 10.

According to battery 100 of the embodiment of this application, through the air in the dry second chamber 12 that holds of drying unit 40 for the humidity that gets into the first air that holds in the chamber 11 is lower, has reduced the first probability that holds the air condensation in the chamber 11 and become the comdenstion water, and then has reduced the comdenstion water and has leaded to safety risks such as battery 100 short circuit striking a fire, insulation failure, has improved battery 100's security.

While the application has been described with reference to a preferred embodiment, various modifications may be made and equivalents may be substituted for elements thereof without departing from the scope of the application. In particular, the technical features mentioned in the embodiments can be combined in any way as long as there is no structural conflict. The present application is not intended to be limited to the particular embodiments disclosed herein but is to cover all embodiments that may fall within the scope of the appended claims.
