Blackground
The compaction density of the powder materials is not only related to its particle size and distribution, but also closely effect the capacity, internal resistance and the cycling performance of the produced lithium-ion batteries (LIBs). Theoretically speaking, the higher the compaction density, the higher the capacity of the LIB can be. Therefore, the compaction density is used as one of the key indicators to evaluating the energy density of materials. The compaction density is closely related to the intercalation and deintercalation of lithium ions during the cycling.
Appropriate compaction density can effectively increase the capacity of the LIB reduce internal resistance, reduce polarization loss, and prolong the overall service life of the battery. On the one hand, the measurement of powder compaction density can be used as an effective index to monitor the differences between batches of powder materials, and on the other hand, it can be used as an effective means of R&D material evaluation and process optimization.
Creative Solution
