The capacity ratio between the negative and positive electrodes (N/P ratio) is a simple but important factor in designing high-performance and safe lithium-ion batteries. However, existing research on N/P ratios focuses mainly on the experimental phenomena of various N/P ratios.

How do NP ratios affect the degradation rate of batteries?

For batteries with relatively fast positive degradation, the N/P value will gradually increase with cycling; on the contrary, for batteries with relatively fast negative degradation, the N/P value will gradually decrease. Therefore, the design of the final NP ratios needs to consider the degradation rate of PE and NE materials as well.

What happens if a positive electrode has a high n/p ratio?

By contrast, the positive electrode of cell with N/P ratio of 1.2 exhibits severe polarization with cycling, which implies that the degradation of the cell with high N/P ratio is dominated by cathode-driven side reaction.
