Tian Xiaobo made a topic presentation entitled "Looking at the Future Trend of Japan and South Korea Baking Process" in the ABEC 2019 Forum, sharing the dynamic battery vacuum drying background, vacuum drying equipment classification and status quo, vacuum drying equipment development trend, battery The net collection has been selected from the reading of the reader:Tian Xiaobo said that the positive material has strong water absorption, the main source of the moisture content, and the impact of moisture on the performance of the power battery is mainly manifested in the following three aspects:
First, the first charge and discharge capacity: When the water is less than 0.015% in the battery, the battery first discharge capacity is in accordance with the national standard and has a small change; when the battery moisture is in the range of 0.015% ~ 0.04%, the battery first discharge capacity with the battery in the battery. Increase and decrease.
