Currently, the main drivers for developing Li-ion batteries for efficient energy applications include energy density, cost, calendar life, and safety. The high energy/capacity anodes and cathodes needed for these applications are hindered by challenges like: (1) aging and degradation; (2) improved safety; (3) material costs, and (4) recyclability.
This discovery could improve the performance and life expectancy of a range of rechargeable batteries. Lithium-ion batteries power everything from smart phones and laptops to electric cars and large-scale energy storage facilities. Batteries lose capacity over time even when they are not in use, and older cellphones run out of power more quickly.
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.
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.
Almost always, battery scientists and engineers have tested the cycle lives of new battery designs in laboratories using a constant rate of discharge followed by recharging. They repeat this cycle rapidly many times to learn quickly if a new design is good or not for life expectancy, among other qualities.
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.
For the degradation, current EV batteries normally have a cycle life for more than 1000 cycles for deep charge and discharge, and a much longer cycle life for less than 100 % charge and discharge (Fig. 8 c) . For most storage applications over 1 day, one needs to ensure a shallow charge-discharge protocol is followed.

These should have more energy and performance, and be manufactured on a sustainable material basis. They should also be safer and more cost-effective and should already consider end-of-life aspects and recycling in the design. Therefore, it is necessary to accelerate the further development of new and improved battery chemistries and cells.
