Description

Technical Field

[0001] The present invention relates to the technical field of cache tanks, and in particular to an intelligent cache tank for electrolyte of a new energy lithium battery. Background Art

[0002] As one of the key technical components, the performance and stability of the electrolyte intelligent cache tank are directly related to the overall efficiency and safety of lithium batteries. However, a problem that cannot be ignored in this system is that the electrolyte will inevitably produce a certain amount of gas when it is running for a long time or under the influence of the external environment. The accumulation of these gases not only gradually occupies the valuable space originally used to store electrolytes, but also directly leads to a significant reduction in the effective contact area between the electrolyte and the positive and negative electrodes of the battery. This change is like setting up an invisible barrier inside the battery, which seriously hinders the smooth transmission of ions during charging and discharging, thereby weakening the energy conversion efficiency of the battery, making the battery seem powerless when providing power, and the overall performance is greatly reduced. Some of the accumulated gases are not inert, they may contain active ingredients that can react with the chemicals in the electrolyte. These unexpected chemical reactions often cause changes in the chemical properties of the electrolyte and even generate some byproducts that are harmful to the battery. These by-products not only further deteriorate the internal environment of the battery, but may also accelerate the aging process of the battery, just like quietly speeding up the hands on the battery life timer, causing batteries that were originally designed for a long life to enter the decline period prematurely, seriously restricting the application life and reliability of new energy lithium batteries.

[0003] At present, the existing new energy lithium battery electrolyte intelligent cache tanks on the market seem to be unable to deal with this problem. Most of them lack automatic and timed gas emission mechanisms, which makes it difficult to solve the gas accumulation problem in a timely and effective manner, thereby indirectly affecting the working efficiency and service life of the battery. More importantly, the existing gas emission operations often rely on manual work, which not only increases the operating costs, but also places extremely high demands on the workers' professional skills and protective measures. After all, the emitted gas may contain toxic and harmful substances, which, if not handled properly, can easily pose a threat to the health of the operators.

[0004] In view of this, this application is hereby filed. Summary of the invention
