6 FAQs about [Residual value of flow batteries]

How do you determine the residual value of a battery?

Battery appearance [7, 8], charge/discharge curves [, , ], open-circuit voltage [10, 11], capacity , and internal resistance [13, 14] are all typical methods for determining the residual value and categorizing batteries.

Why is a battery not suitable for a residual value assessment?

However, because they are external features of the battery, capturing its internal electrochemical state in depth is difficult, and obtaining features such as charge/discharge curves and capacity takes a long time, making them unsuitable for residual value assessment of large-scale RBs.

How to maximize residual value of retired batteries before Cascade utilization?

Cascade utilization of retired batteries is considered one of the most promising disposal methods. However, to maximize the residual value of these batteries before cascade utilization, it is necessary to estimate their residual capacity and perform consistency sorting.

What are the methods for estimating residual capacity of retired batteries?

Currently, the methods for estimating the residual capacity of retired batteries are mainly classified into two main categories: direct and indirect estimation methods. Direct estimation methods include (i) CC; (ii) OCV; and (iii) Electrochemical impedance spectroscopy (EIS).
