Cycle performance is critical for solar batteries, and it cannot be stressed. Longer cycle life means less resource usage on a macro level.
Cycle performance is critical for solar batteries, and it cannot be stressed. Longer cycle life means less resource usage on a macro level. As a result, everyone involved in the power storage industry is a factor affecting the cycle performance of solar batteries. There are a number of issues that must be examined.
Excessive water will cause negative and positive active materials to react negatively, destroying their structure and affecting circulation. At the same time, too much water will prevent the SEI film from forming. While trace water is difficult to eliminate, the performance of the battery can be guaranteed to a degree.
Compaction of positive and negative electrodes
Excessive compaction of the positive and negative electrodes can enhance the cell’s energy density, but it can also degrade the material’s cycle performance to some amount. According to a theoretical analysis, the higher the positive and negative compaction, the greater the structural de to the material, which is the basis for ensuring that the solar battery can be recycled; additionally, it is difficult for cells with higher positive and negative compaction to ensure a higher liquid retention, which is the normal cycle or more cycles basics of the cells.
