Embodiment Construction

[0070] The present invention will be further described through embodiments below in conjunction with the accompanying drawings.

[0071] figure 1 is a schematic diagram of a cylindrical battery according to an embodiment. Such as figure 1 As shown, the injection port 101 and the discharge port 102 of the cylindrical battery 1 are respectively arranged on the two opposite end surfaces of the battery case, and the injection port 101 and the discharge port 102 are both arranged at the center of the end surface, and the fluid injected into the cylindrical battery from the injection port 101 The winding part of the electric core can be entered through the flow opening on the side wall of the electric core. The positive pole 103 and the negative pole 104 are located on the same end surface of the battery case as the injection port 101, and the positive pole 103 and the negative pole 104 are deviated from the center of the end surface.

Abstract

The invention provides a liquid injecting and liquid replacing device for a cylindrical battery, wherein the liquid injecting and liquid replacing device is provided with a liquid injecting and discharging device and a battery rotating device. According to the invention, the battery rotating device can be fixedly connected with at least one part of a cylindrical battery, and the battery rotating device can be connected with the rotating shaft of a motor, so that the motor drives the battery rotating device to rotate so as to further drive the cylindrical battery to rotate; the liquid injectingand discharging device comprises a rotating part rotating together with the cylindrical battery and a fixing part used for being in butt joint with an external fluid storage device/fluid recovery device, wherein the fixing part is connected to the rotating part in a sleeving manner and is internally in fluid communication, so that the cylindrical battery can be in fluid communication with the external stationary fluid storage device/fluid recovery device while rotating; and under the action of centrifugal force, the liquid injected into the cylindrical battery can fully infiltrate the whole battery core, or the liquid in the battery core in the cylindrical battery can be thrown out and new liquid can be continuously injected to quickly replace the original liquid.

Description

technical field [0001] The invention relates to the field of batteries, in particular to a liquid injection and liquid replacement device and a liquid injection and liquid replacement method for cylindrical batteries. Background technique [0002] Lithium slurry battery is a new type of lithium-ion battery with low cost, long life, high safety and easy recycling. Since lithium slurry itself has a dynamic contact conductive network, it can avoid the loss or loosening of traditional lithium-ion battery electrode materials. Problems such as battery capacity decline and cycle life attenuation. Cylindrical lithium slurry batteries using a winding method can greatly simplify the processing technology of electrode sheets, and have obvious manufacturing cost advantages. [0003] One of the salient features of lithium slurry batteries is that the battery can be maintained and regenerated, so it needs to undergo multiple liquid injection and liquid replacement processes during its pr...
