6 FAQs about [New energy battery attenuation technology principle]

What causes attenuation of battery power performance?

The attenuation of battery power performance results from capacity decay and impedance growth . In the battery community, empirical models are mainly used to predict the aging of the cell.

Is battery-lifespan attenuation a hybrid optimization method for battery/pumped hydro energy storage?

What happens if a battery runs without a lifespan attenuation?

Therefore, if the battery operates without considering lifespan attenuation, the cost of replacing the battery beyond the project period must be considered, thereby resulting in a considerably high overall system cost.

Does attenuation of battery capacity change electrode OCV?

In our previous work , we found that the attenuation of battery capacity will lead to the change of electrode OCV.

How to identify the aging mechanism of a battery?

To identify the aging mechanism of the battery by using the OCV curve of electrodes, it is necessary to establish the correlation model between the aging and the OCV curves. Besides, considering that the SOC i of the electrode can not be measured directly, it is necessary to map the SOC of the whole battery to the electrode SOC i.
