Follow-on. Here is an article on all the wonderful advances that are "just around the corner." I read this SAME stuff in an article dated 8 YEARS ago. It's all pie-in-the-sky, and no one seems to know why none of the hurdles can be crossed. It's like the farce that is hydrogen fuel cells. 50 years of work, and virtually no real progress. Or progress in cracking water using lower energies.

Why do you talk about things you know nothing about?

Fuel cells have advanced dramatically in the last 20 years and electrolysis energy has dropped from around 80kWh per kg to around 50.

No , the problem is that you don't see and can't see.

So tell me then why no substantive progress has been made in nearly a decade?

It has - 5-7% a year or so.

The batteries I had in DSLRs that long ago were as good or better in-terms of storage than the stuff I see now.

Nope...a bit worse.

10 years, 1865mAh vs 1390mAh, exact same size

Voltage is different (higher in old one) and there simply could be more material in the battery, so not a good  example.

Right. You realise that you have not offered a reasonable contradiction, but a bald denial with no actual information?

You just don't know anything about batteries.

These are both lithium-ion batteries.  Such batteries generally have a voltage range of 3.6V (when nearly dead) to 4.2V (when at 100%).  Some are rated nominally at 3.6V, some at 3.7V, but this is an arbitrary rating since the chemistry is the same.

I offered one real and one plausible reason for why the battery might be capable of delivering more power.

Nope. You offered uniformed speculation, there is actually a difference.
