I did wonder about charge-discharge cycles.

Brenton, I had not heard about the Li-S work.

I am hoping someone finds a better battery. 

Has anyone heard any positive news about Hydrogen Fuel Cells recently?

I keep hearing how "one day" it will be the way forward. 

I guess Hydrogen Fuel Cells are not going to help rovers and drones get around on Mars though, "The estimated mean volume ratio of molecular oxygen (O2) in the Martian atmosphere is 0.174%"
