2. Wuhan Get. High-temperature aging rooms, thermal aging chambers, drying ovens, and high-temperature test chambers are all temperature testing equipment, but they differ in specifications, functions, and standards.

Difference between ambient aging and high-temperature aging

1. Based on the establishment of the Arrhenius acceleration model, applying the time-temperature superposition principle, the translation factor at room temperature was obtained through linear extrapolation of the high-temperature shifting factor. This led to the creation of a prediction equation for the aging performance degradation of rubber at room temperature, which was then compared with实测 room temperature aging performance degradation data.

2. Aging typically refers to the placement of batteries after the assembly and filling process, before the first charge, which can be done at normal temperature or high temperature. Both methods 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-formation process, the graphite anode inside the battery forms a certain amount of SEI film, but 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 battery's voltage is unstable after formation, 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 temperature 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 power-on 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 ambient temperature. Since the device undergoes aging at a higher ambient temperature, the junction temperature of the integrated circuit can reach very high levels.

4. Lithium-ion battery aging generally refers to the storage after the battery is assembled and filled with electrolyte, and it comes in two types: normal temperature aging and high temperature aging. Both are designed 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, with some using 38 degrees and others 45 degrees. The aging time is typically between 48 to 72 hours. Lithium-ion battery aging also involves two scenarios: open and sealed. For batteries that are open-cycled, it's better to seal them after aging if the relative humidity can be controlled below 2%. For high temperature aging, it's preferable to age them after sealing. However, it is certain that the aging process of the battery involves electrochemical kinetic 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

1. Room temperature aging temperature is 25 degrees, with high temperature aging varying by manufacturer, ranging from 38 to 45 degrees. Aging time is between 48-72 hours. For lithium-ion batteries, aging is divided into two types: open and sealed. Regarding batteries to be sealed after room temperature aging, 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. General aging procedures include: charging to 0-2V, storing at room temperature for 7 days, and then storing at 45°C for 7 days. Disqualify products with voltage differences before and after battery aging. Leave the battery open-circuited at high or room temperature for 7 or 28 days. To assess 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, walk-in high temperature aging rooms and controlled temperature aging rooms are a type of product. Both walk-in high temperature aging rooms and controlled temperature aging rooms are named according to temperature. A walk-in high temperature aging room is any room with a temperature higher than room temperature and is called a high temperature aging room. "Controlled temperature aging" literally refers to aging at a specific temperature point.

4. Batteries exhibit enhanced stability in performance after high-temperature aging. The majority of manufacturers producing lithium-ion batteries employ this high-temperature aging process, aging the batteries for 1 to 3 days at temperatures between 45 to 50 degrees Celsius, followed by storage at room temperature. Post high-temperature aging, potential issues such as voltage fluctuations, thickness changes, and internal resistance variations become apparent, all of which directly test the safety and electrochemical performance of the batteries. Currently, most battery companies use low-quality domestic separators for mass production, making high-temperature aging a concern for the internal structural safety of batteries. To shorten the overall production cycle, new batteries aged at high temperatures only accelerate the chemical reactions without causing significant damage. The batteries are then left at room temperature for over three weeks, allowing for a full chemical reaction between the anode and cathode, separator, and electrolyte to reach equilibrium. It is only at this point that the battery's performance is considered more authentic.
