As the core component of EVs, batteries have a significant impact on the environmental performance of EVs. Compared with previous nickel-cadmium (Ni-Cd), lead-acid (Pb-Ac), and nickel-metal hydride (NiMH) batteries (Matheys et al., 2009; Matheys et al., 2007; Steele and Allen, 1998), lithium-ion batteries (LIBs) have the advantages of high energy and …
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.
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.
Prolonging EV battery lifespans plays a major role in determining the EOL EV battery generation in a region. It helps understand the urgency to set up large-scale reuse and recycling infrastructure and strategies to ensure the close loop management of EV batteries.
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.
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

New regulation in China now holds EV makers responsible for the recovery of batteries, requiring them to set up recycling channels and service outlets where old batteries can be collected, stored and transferred to recycling companies.
In this study, we aim at examining the first EOL EV battery generation in Catalonia according to two different battery lifespan scenarios. The ''reduced battery service'' scenario considers that batteries have a constant lifetime of 10 years, the current average EV battery lifespan (EUROSTAT, 2020).
A new study from the SLAC-Stanford Battery Center indicates that electric vehicle (EV) batteries may last significantly longer in real-world conditions than previously anticipated. By testing batteries with dynamic discharge profiles that mimic actual driving scenarios, researchers found that these conditions could extend battery life, debunking some …
