I am using "x" to mean that the line item is addressed by the article. Sorry, I guess that's backwards from the original intent of the checklist.

I am saying that the article addresses every reason for doubt that the checklist raises (save for the last, which it can't). Whether the technology actually addresses that shortcoming is another question, but the article does claim to have solved every single one of those common drawbacks.

As for the item about li-ion advances, I think the claimed capabilities are well beyond what li-ion could reasonably be expected to reach in the short remaining timeframe claimed.

tl;dr: the checklist is a cynical but normally accurate way of spotting fatal flaws in newly announced battery technology. Based on the announcement, this technology suffers from none of the flaws listed therein.
