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.
The accumulated energy potentially can reach a certain percentage (<∼20%) of the maximum energy of a rechargeable battery at the end of its lifetime if no voltage decrease is assumed when the battery capacity reaches 80% of the initial maximum capacity.
This is not a good way to predict the life expectancy of EV batteries, especially for people who own EVs for everyday commuting, according to the study published Dec. 9 in Nature Energy. While battery prices have plummeted about 90% over the past 15 years, batteries still account for almost a third of the price of a new EV.
Consumers’ real-world stop-and-go driving of electric vehicles benefits batteries more than the steady use simulated in almost all laboratory tests of new battery designs, Stanford-SLAC study finds. The way people actually drive and charge their electric vehicles may make batteries last longer than researchers have estimated. | Cube3D
(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.
Do Electric Cars Lose Charge When Parked? (Beware Vampire Drain!)
In light of the explanation I gave above, the simple answer is that most likely yes, your EV is losing some amount of charge while parked and idle.If you''re still plugging your car in each day and maintaining the charge level between 20 and 80 percent, then the amount you''ll lose to vampire drain will be minimal can only happen when the car is sitting and not …

How Do Batteries Lose Their Energy? (Answered With Explanation)
Batteries will lose energy even when not in use due to the self-discharge rate of the battery. Heat and cold can also contribute to the rate of energy loss. Batteries can be recharged to restore their energy, but over time the battery will lose its capacity to hold a charge. To extend the life of a battery, be sure to properly store the battery ...

Energy and Power Evolution Over the Lifetime of a Battery
Most batteries have <∼95% energy efficiency in one charge/discharge cycle. (3)) The latter portion, as the irreversible electrochemical energy, is part of the round-trip energy loss and it accumulates in a battery with continuous cycling (accumulation of the side products at cathodes and anodes).
