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.
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.
As a battery operates, a major portion of the battery energy (related with reversible capacity) can be reversibly increased or decreased by converting from or back to electricity.
The continued investment in new battery materials, novel battery structures, advanced manufacturing processes, and accelerated testing/validation of battery performance has led to significant progress in battery development and deployment.
State-of-health is one set of the key data metrics used for determining end-of-life for a battery. In addition to energy, battery power is another important parameter to consider in battery aging.
(1) As a battery degrades, its power fades along with the capacity/energy, while the fading may be at different rates because of the different degradation mechanisms of various battery chemistries. Similar to battery energy, the power fade in a battery is also a critical parameter in determining the battery’s specific applications and lifetime.
