Memory foam battery concept fits all devices

What you didn’t make clear to the layman is what ‘concept’ means; it’s not in market production, yet. So it may not even be viable.

I’m surprised nobody has yet mentioned the inherent dangerousness of this product. You ever pull a freshly-charged battery out of its charger? It’s warm, isn’t it? Now imagine putting a thick foam blanket around the battery, then charge it. It would probably get very hot, possibly hot enough to melt the foam and quite likely start a fire if the internals explode. Not a good “concept” at all.
