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.
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.
Then there might be improved lithium-ion batteries, maybe using silicon anodes or rocksalt cathodes, for mid-range vehicles, or perhaps solid-state lithium batteries will take over that class. Then there might be LiS or even lithium–air cells for high-end cars — or flying taxis. But there’s a lot of work yet to be done.
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.
New energy vehicles (NEVs) are considered to ease energy and environmental pressures. China actively formulates the implementation of NEVs development plans to promote sustainable development of the automotive industry. In view of the diversity of vehicle pollutants, NEV may show controversial environmental results.
As energy shortage, climate change, and pollutant emissions have posed significant challenges to the sustainable development of the world automotive industry, the development of new energy vehicles, represented by electric vehicles (EVs), has received considerable attention from various countries and has gradually become a worldwide consensus .
