3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
complementary specific capacity of the lithium supplement
difference between the initial charge specific capacity and the initial discharge specific capacity under specified conditions
3.2
moisture resistance performance
ability to resist erosion in humid environments within a defined time and humidity range
Note: Expressed by moisture absorption rate. A lower absorption rate indicates stronger resistance to humid environments, i.e., better moisture resistance performance.
4 Product classification
The products are divided into three categories: LFO-Ⅰ, LFO-Ⅱ and LFO-Ⅲ according to the complementary specific capacity of the lithium supplement.
