Onori and her colleagues determined, however, that this is not an ideal approach for predicting the life expectancy of EV batteries — a find of particular importance, since batteries still account for about a third the of price of a new EV.
Battery scientists and engineers have typically tested the cycles of new batteries in laboratories, using a constant rate of discharge, followed by recharge, the authors explained. They then repeat this approach many times to learn if a new design could benefit the battery’s longevity.
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.
They then evaluated 92 commercial lithium-ion batteries for more than two years across these profiles. The more realistic the profiles, the higher the EV life expectancy rose, according to the study.
Going forward, the researchers said that carmakers could update their EV management software to take advantage of the new findings — helping maximize battery life in real-world settings.
The culprit behind the degradation of lithium-ion batteries over time is not lithium, but hydrogen emerging from the electrolyte, a new study finds. This discovery could improve the performance and life expectancy of a range of rechargeable batteries.
