However, according to the physical meaning, reaction energy can only represent whether the reaction is thermodynamically favorable, but not the kinetically feasibility. What''s more, in the Arrhenius equation, the activation energy (reaction barrier) should be the determinant of the reaction rate. Secondly, electrically conductive products in

The battery energy at the end-of-life depends greatly on the energy status at the as-assembled states, material utilization, and energy efficiency. Some of the battery chemistries still can have a significant amount of energy at the final life cycle, and special care is needed to transfer, dispose of, and recycle these batteries.
However, a rough estimation of the battery energy evolution as shown in Figure 1 is sufficient to draw general conclusions: The battery energy at the end-of-life depends greatly on the energy status at the as-assembled states, material utilization, and energy efficiency.
Regeneration, if successful, doubles the battery’s lifespan, potentially allowing for multiple regeneration cycles. If regeneration becomes unviable, the battery can be repurposed or recycled, contributing to a substantial extension of its life cycle and mitigating material usage and waste at the end of its operational life.
A portion of the energy is either lost through the inevitable heat generation during charge/discharge or retained as irreversible electrochemical energy in the battery through parasitic chemical/electrochemical reactions of electrolyte and formation of side products.
The passage of an electric current even when the battery-operated device is turned off may be the result of leakage caused , for example, by electronically slightly conductive residues of dirt on the battery surface, the battery holder, or mechanical and chemical processes inside the battery .
