2. Wuhan Get. High-temperature aging rooms, thermal aging chambers, desiccators, high-temperature test chambers, and other equipment all belong to temperature testing equipment, but they differ in specifications, functions, and standards.

Difference between room temperature aging and high temperature aging

1. Based on the establishment of the Arrhenius acceleration model, applying the principle of time-temperature superposition, we obtain the translation factor at room temperature through linear extrapolation of the high-temperature translation factor. This allows us to establish a prediction equation for the aging performance degradation of rubber at room temperature, which was then compared with measured data on the aging performance degradation of rubber at room temperature.

2. Aging generally refers to the placement after the battery is assembled and filled with liquid, which can be either at normal temperature or high temperature aging. Both serve to stabilize the properties and composition of the SEI (Solid Electrolyte Interphase) film formed after the first charge, ensuring the stability of the battery's electrochemical performance. The main purposes of aging are threefold: After the battery undergoes the pre-forming process, a certain amount of SEI film forms on the internal graphite anode. However, this film has a dense structure with small pores. Aging the battery at high temperature helps to restructure the SEI, forming a loose and porous film. The voltage of the battery after forming is in an unstable stage, slightly higher than the actual voltage. The purpose of aging is to make the voltage more accurate and stable. Placing the battery at high or normal temperatures for a period of time ensures that the electrolyte can fully wet the electrodes, which is beneficial for the stability of the battery's performance.

3. The charging method and test circuit form for high-temperature static power aging are the same as those for normal temperature static power aging, with the difference being that the former is conducted at a higher environmental temperature. As the device undergoes aging at a higher environmental temperature, the junction temperature of the integrated circuit can reach very high levels.

4. Lithium-ion battery aging generally refers to the placement after the battery is assembled, filled with electrolyte, and charged. There are two types: normal temperature aging and high temperature aging, both of which serve to stabilize the properties and composition of the SEI (Solid Electrolyte Interphase) film formed after the first charge. The normal temperature aging temperature is 25 degrees Celsius, while the high temperature aging temperature varies by manufacturer, ranging from 38 to 45 degrees Celsius. The aging time is typically between 48 to 72 hours. Lithium-ion battery aging also comes in two cases: open and sealed. For batteries that are open after formation, it's better to seal them after aging if the relative humidity can be controlled below 2%. For high temperature aging, aging after sealing is preferable. However, it can be confirmed that the aging process of the battery involves electrochemical dynamics changes, which greatly benefit the stability of the SEI film and promote the stability of the electrochemical system.

Battery normal temperature aging vs. high temperature aging区别

1. Ambient aging temperature is 25 degrees, with high-temperature aging varying by manufacturer, ranging from 38 to 45 degrees. The aging time is between 48 to 72 hours. For lithium battery aging, there are two cases: open and sealed. For batteries that are aged at room temperature, it's better to seal them after aging if the relative humidity can be controlled below 2%. As for high-temperature aging, after sealing...

2. The general aging process includes: charging to 0-2V, storage at room temperature for 7 days, storage at high temperature (45°C) for 7 days, and removing defective products by checking the voltage difference before and after battery aging. Leave the battery open-circuited at high temperature or room temperature for 7 days or 28 days. To determine its self-discharge performance, measure the discharge capacity by discharging the battery to the cutoff voltage.

3. The difference between room temperature aging and high-temperature aging is that, in a general sense, both walk-in high-temperature aging rooms and constant-temperature aging rooms are considered a single product. Both are named based on temperature; a walk-in high-temperature aging room refers to any room with temperatures above room temperature as high-temperature aging rooms, while constant-temperature aging refers to aging at a specific temperature point.

4. Batteries exhibit increased stability in performance after high-temperature aging. The vast majority of manufacturers producing lithium-ion batteries employ high-temperature aging processes, aging the batteries at temperatures of 45 to 50 degrees Celsius for 1 to 3 days, followed by normal temperature storage. After high-temperature aging, potential issues such as voltage fluctuations, thickness changes, and internal resistance variations are revealed, all of which directly test the battery's safety and electrochemical performance. Currently, most battery companies use low-quality domestic separators for mass production, making high-temperature aging a concern for internal structural safety. To shorten the overall production cycle, new batteries under high temperatures only accelerate the battery's chemical reactions, causing minimal damage. Batteries are then stored at room temperature for over three weeks, allowing for full chemical reactions between the anode, cathode, separator, and electrolyte to reach equilibrium. It is only at this point that the battery's performance is considered more authentic.
