Plus these would be coin sized, but 100X more dense as I understand.

100x their current solid state batteries, not Lithium Ion. Maybe only 2x.

Still, doubling an Apple Watch’s battery life or 1.5x but making it smaller would still be great.

Apple Watch's battery life is the biggest negative by far for the device in my books. Any thing to improve it would be welcomed by pretty much anyone. Extra points for being able to replace existing battery--yeah right
