The study shows that the buildup on battery electrodes is a side effect, not the root cause, of performance loss.
Researchers found that the solid electrolyte interphase layer is semi-conductive, allowing electron leakage and impacting battery life.
This research could lead to the development of better batteries with extended lifecycles and minimized capacity losses.
“Even slight variations of the rate of conduction through the SEI can result in dramatic differences in efficiency and battery cycling stability,” Wang added.
I take it the leakage means increased self-discharge?
And the 'efficiency' referred to is ratio of stored charge to Ampere-hours recharging current?

It's out of PNNL and is MAJOR news for battery researchers and manufacturers and OEMs who use them.https://oilprice.com/Energy/Energy-General/Breakthrough-Research-Unveils-True-Cause-of-Battery-Degradation.htmlSloman Rating: "on-topic" - science, 0

It's out of PNNL and is MAJOR news for battery researchers and manufacturers and OEMs who use them.It's not major news - nobody has used it to make better batteries yet, and while the inventors are hopeful that it might be exploited to do that, it may just be a much of an irrelevant distraction as the interest in dendritic lithium deposits was
It is science - rather than electronicis - so less "on-topic" and helpful rather than useful, so +1.

Characterizing and quantifying the conductance of the SEI has been an open question for over a decade. Since a more complete understanding contributes directly to battery performance, the lab finally cut loose about a million bucks for the reportedresearch. You can get an idea of what's going on by scoping out 'references' in the sidebar. You don't need a subscription to see them.
I'm assuming the myriad of people interested in this SEI are not doing it as an avocation, but because they're actually designing batteries.
