Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed a new lithium metal battery that can be charged and discharged at least 6,000 times — more than any other pouch battery cell — and can be recharged in a matter of minutes.
“It is already competitive with incumbent technologies, and it can save a lot of the cost and pain and environmental issues related to mining the metals that currently go into batteries.” Dincă is the senior author of the study, which appears today in the journal ACS Central Science.
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.
Lithium-sulfur batteries have never lived up to their potential as the next generation of renewable batteries for electric vehicles and other devices. But ?SMU mechanical engineer Donghai Wang and his research team have found a way to make these Li-S batteries last longer -- with higher energy levels -- than existing renewable batteries.
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
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.
MIT researchers have now designed a battery material that could offer a more sustainable way to power electric cars. The new lithium-ion battery includes a cathode based on organic materials, instead of cobalt or nickel (another metal often used in lithium-ion batteries).

The company has scaled up the technology to build a ...
In thermodynamic terms, a brand-new main battery and a charged secondary battery are in an energetically greater condition, implying that the corresponding absolute value of free enthalpy (Gibb''s free energy) is higher [222, 223]. Distinguishing statements must take into account the fact that discharge is a spontaneous process, which results in values carrying a negative sign. The …
