Did anyone question the existence of this asymmetry? Where?
I have questioned this claim and asked you to provide any evidence:
As we have seen, the graphs in the referenced study do NOT provide such evidence (if one looks at the RELEVANT cases, with DOUBLE charge rate). Any other study you...
The problem is, you made specific quantifiable claim which is not supported by this graph. You said: "In extreme cases doubling the charge rate can reduce life by a factor of 10 or more". Therefore, in the graph, we are looking to compare cases marked "C charge" with "C/2 charge", and "C/5...
I have pretty strong idea what lies at the source of your confusion, but I am going to keep it to myself out of politeness. Who exactly (besides yourself) considers cells end-of-life when they reach 80% nominal capacity?
I read that study long time ago. It is very interesting, but It contains NOTHING to substantiate your claim.
Please provide exact quote from the study which you think supports your claim.
Or is it too much to ask?
Where did I say scientific studies are based on intuition?
The study you referenced is great, but it contains NOTHING to substantiate your claim:
So, once again, can you substantiate your claim in any way?
I suggest that in addition to reading studies, we should refrain from making definitive statements if the only thing we can back them up with is "intuition".
Beautiful argument! The statement is wrong, because if it were right, someone would have made it earlier :-)
