Use advice for data set
The dataset for Process D should be implemented for Life Cycle Assessment (LCA) purposes with careful consideration of its limitations. Users need to be aware that the process data is derived from an average of reported literature data from 2013 to 2017, and may not include certain environmental impacts, labor costs, and infrastructure expenses. Recycling or treatment of plastics and metal casings are excluded from this study. Additionally, the data has regional specificity; it is adapted to Chinese conditions and may not reflect other geographic contexts accurately. The data should not be used indiscriminately for industries or regions other than those it was intended for, without appropriate adjustments for local circumstances. The baseline period for the referenced data is a 4-year average from 2013 to 2016, and may require updating for accuracy in future applications.

General comment
The leaching of waste electrode materials with strong acid and reducing agent is characterized by low price, but the strong acid is not selective for the leaching of various metals in the electrodes, and the subsequent separation process is difficult and the purity of the products is low, resulting in the waste of part of the valuable resources.

Technical purpose
This hydrometallurgical process (Process D) utilizes a combination of strong inorganic acids and reducing agents to leach waste electrode materials from lithium-ion batteries (LIBs). Although the process is economical, it lacks selectivity in the leaching of metals from the electrodes, leading to challenging separation stages and lower purity of final products. The data set characterizes this process for its use in recycling and resource recovery industries, specifically applied to the recycling of LIB electrode materials. As such, Process D may serve as a feasible, though non-optimal, solution for businesses or facilities interested in cost-effective but less efficient resource recovery options.
