The invention relates to a secondary injection device of a battery and a method for injecting electrolyte into a battery. The secondary injection device of the battery includes a frame and a plurality of support rods; wherein the frame includes a frame body and connecting plates, and the connecting plates are positioned on the side surface of the frame body; at least one ends of the support rods are connected onto the connecting plates, the support rods form a placement position used for placing the battery. After precharging and before packaging, the battery is placed on the placement position formed by the support rods, the frame is immersed in electrolyte, and the electrolyte is injected to the battery for the second time, so as to complement the loss electrolyte when precharge, and the loss of electrolyte is effectively reduced, meanwhile, the security and circularity of the battery are ensured; when the electrolyte is injected into the battery for the second time, the battery has voltage, while the electrolyte which belongs to flammable liquid is an organic solvent, short circuit and ignition are easily caused if the operation is careless, so that the security is improved by injecting electrolyte into the battery for the second time through the secondary injection device.
Description
technical field [0001] The invention relates to the technical field of battery production, in particular to a battery secondary liquid injection device and a battery liquid injection method. Background technique [0002] With the development of smart phones, the requirements for their working power are getting higher and higher. Taking lithium-ion batteries as an example, while pursuing the maximum capacity of the battery, the battery is developing towards thin, wide, and high profile. Due to the limited internal space of the battery, when the internal space is filled with the active material to the maximum, the remaining electrolyte space is relatively reduced, and the electrolyte is used as the transmission medium of lithium ions inside the lithium-ion battery. Once reduced, it will inevitably affect the safety performance of the battery. have a great impact. In the production of lithium-ion batteries, processes such as liquid injection, pre-charging, and sealing are gene...
