Here, Zhou et al. use real-world data from retired lithium-ion batteries and develop a neural network for capacity estimation with reduced need for charge-discharge testing.
With the large-scale retirement of power lithium-ion batteries in electric vehicles, the appropriate disposal of retired batteries (RBs) has become an important concern. Evaluating the residual value and exploring secondary applications for RBs are considered promising technical approaches.
From both theoretical and practical aspects, the cells with average voltage in the battery pack are selected as representative cells and their residual energy is estimated as the residual energy of the battery pack at the current moment.
As electric vehicles (EVs) become increasingly mainstream, the question of battery longevity and its impact on vehicle residual value is often raised. Batteries, which constitute 20–30% of an EV’s cost, are seen as a critical component determining the long-term economic feasibility of these vehicles.
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.
Hydrometallurgical, pyrometallurgical, and direct recycling considering battery residual values are evaluated at the end-of-life stage. For the optimized pathway, lithium iron phosphate (LFP) batteries improve profits by 58% and reduce emissions by 18% compared to hydrometallurgical recycling without reuse.
