Will the aluminum case of power lithium-ion battery age?

As the application of power lithium-ion batteries becomes more and more extensive, there are more and more applications of power lithium-ion battery aluminum shells, but will the power lithium-ion battery aluminum shells age after being used for a long time? Airline technicians explain to you the aging phenomenon of the aluminum case of power lithium-ion battery? Aluminum power lithium-ion battery case capacitor is an indispensable consumable component in the circuit. Generally, if the capacitor is aging due to overvoltage, overheating, and electrochemical corrosion, the charge and discharge time will be very short, and it will even be broken down, causing electrolyte leakage and solidification to directly short-circuit. The principle is: overvoltage and overheating Will cause the flow inside the electrolytic particles to be abnormally active, thereby forming the escape plate stamping, overheating, especially this phenomenon is more obvious, directly manifested as the capacitor burning and blackening, to a certain extent, the overvoltage phenomenon will directly lead to overheating . Power lithium ion battery aluminum shell working electrolyte uses weak acid/weak alkali salt as electrolyte, water and organic solvent as solvent, but it still has certain corrosive use for the anodic oxide film and rubber plug of capacitor power lithium ion battery. In addition, the electrolyte salt and the solvent will also undergo a certain chemical reaction over time. These phenomena will cause the deterioration of the electrical performance of the capacitor power battery. Therefore, the aluminum shell of power lithium-ion battery is also prone to aging. Will the aluminum case of power lithium-ion battery age? That's it. The aluminum shell of power lithium ion battery is prone to aging, so we must prevent these phenomena from happening to prevent aging. We also discussed the factors that affect the quality of the aluminum case of power lithium-ion batteries, which can be combined to know.
