Information

The importance of cycle performance to solar batteries does not need to be overstated. From a macro perspective, longer cycle life means less resource consumption. Therefore, the factors affecting the cycle performance of solar batteries are every person related to the power storage industry. issues that have to be considered.

1. Moisture
Excessive water will cause side reactions with the positive and negative active materials, destroy their structure and affect the circulation. At the same time, too much water is not conducive to the formation of the SEI film. However, while the trace water is difficult to remove, the trace water also The performance of the battery can be guaranteed to a certain extent.

2. Positive and negative electrode compaction
Excessive compaction of the positive and negative electrodes can increase the energy density of the cell, but it will also reduce the cycle performance of the material to a certain extent. From a theoretical analysis, the greater the compaction, the greater the structural damage to the material, while the The structure of the material is the basis to ensure that the solar battery can be recycled; in addition, it is difficult for the cells with higher positive and negative compaction to ensure a higher liquid retention, and the liquid retention is the normal cycle or more cycles basics of the cells.
