And that’s basically it!
every cycle of charge and discharge causes batteries to expand and contract, similar to human breathing. This action causes battery components to warp just a tiny amount, putting strain on the battery and weakening it over time.
I like when scientists have fun with describing things.
When my door sticks on humid days I should say it's because my doorframe is breathing.
'Breathing' is already used for the exchange of outside and inside air for homes. In many contexts it is about the difference in internal and external humidity!
The door frame moving as part of that exchange is close, but not quite accurate.
the door and doorframe swelling from humidity is literally like certain body parts swelling from additional liquids, so you could tell them your foor frame is in heat.

I don't know if they'll appreciate it, but they need to know!

Woodworkers will tell you wood is a living material
Woodworker here. If your wood is still alive, try hitting it with a hammer to put it out of it's misery.
i believe this is the job of science communicators who try to explain complicated processes and ideas so that people outside of that specific scientific field can also understand what's going on
Definitely!
The research team from The University of Texas at Austin, Northeastern University, Stanford University and Argonne National Laboratory found that every cycle of charge and discharge causes batteries to expand and contract, similar to human breathing. This action causes battery components to warp just a tiny amount, putting strain on the battery and weakening it over time. This phenomenon, known as “chemomechanical degradation,” leads to reduced performance and lifespan.
Wasn't this already widely known? I knew about this phenomenon since long ago, it doesn't feel like new discovery
Known in the industry for decades, not independently researched bcs it doesn't matter if you aren't manufacturing it? Maybe they documented it a bit more in the parts that were irrelevant to the industry? Idk, I'm guessing.
Wasn't this widely known already?
They definitely knew batteries cycling causes degradation, but I think this is saying they found additional information on how it happens which might lead to future designs possibly mitigating this cause.
One of the key discoveries was the identification of “strain cascades” —a chain reaction in which stress builds up in one part of the electrode and spreads to neighboring regions.
Yeah I wish the article went into more of those details instead of trying to create an analogy to breathing and the widely known facts about expansion during charging.
There are hints in the article that the study was more detailed, so hopefully this is just a poorly written article trying to “dumb it down” too much
That's basically all scientific journalism. If it was geared only towards people who have advanced knowledge, it would just be the journal article. It has to be dumbed down at least a little bit.
The problem is when the author either doesn't have the advanced knowledge to effectively dumb it down so it's inaccurate, or knowingly misrepresents the study to push an agenda (I see this one a lot)
me lik wen dumb down
What device is that
