Abstract

The invention discloses a lithium battery convenient for air transportation. The battery comprises a shell with a shell structure, a positive electrode and a negative electrode, the inner wall of theshell is in sealed sliding connection with a diaphragm and a conductive plate; the conductive plate is located over the diaphragm, a liquid storage box fixedly connected to the inner wall of the shellis arranged under the diaphragm, a circuit breaking structure is connected into the liquid storage box and comprises a through hole, the middle portion of the liquid storage box is connected with anelectromagnet, and the top and the bottom of the electromagnet are each provided with a piston. The lithium battery has the advantages that the lithium battery is set to be in two states, and the lithium battery is in a working state when the plane where the positive and negative electrodes are located is vertical; when the plane where the positive electrode and the negative electrode are locatedis in a horizontal state, the lithium battery is in a transportation state, the positive electrode and the negative electrode are insulated from each other through oil when the lithium battery is in the transportation state, a micro short circuit phenomenon is avoided, and the lithium battery and an external circuit are kept in a good power-on state when the lithium battery is in the working state.

Description

technical field [0001] The invention relates to the technical field of lithium batteries, in particular to a lithium battery that is convenient for air transportation. Background technique [0002] Lithium batteries are mainly transported by air. In recent years, there have been some unsafe accidents in the transportation of lithium battery goods to varying degrees in air transportation. The reasons include external and internal reasons. On the one hand, the main reason is that the strength of the polymer film is very low. The strong collision between bumps and luggage may damage the film, causing a short circuit in the battery and releasing a lot of heat in a short time. Since the organic electrolyte in the battery is flammable, it may cause combustion or explosion; on the other hand, the process The faults of the battery lead to the excessive length of the electrode tabs of the battery, which may cause an internal short circuit in contact with the pole piece or the casing...
