I'm an actual battery scientist. They wear out much more slowly if you don't charge them all the way

This research was focused on the lithium battery anode. Ideally we could just put a chunk of lithium in there but the stripping and deposition chemistry doesn't work well long term. Modern batteries use graphite instead. But of course you waste a significant amount of cell volume and weight with all of that carbon, and the potential is lower than Li metal. Alloying Li with silicon gets you properties more similar to Li.

So this paper talks about their efforts to make LiSi more viable as an anode. They gave it a coating to protect it from electrolyte side reactions and created a new gel electrolyte formation reaction. The capacity they report isn't remarkably higher than what's out there now since the cathode is the heaviest part of the cell.

As to the results I do have to say 60% capacity retention after 200 cycles is not nearly good enough for real world use. And I have no clue where they got the "1000 mile range" headline from.

More efficient compact X-ray generators would be pretty huge for science work. We run the diffractometer in my lab at 2 kW and it still takes hours to get a good quality scan

Short times are always given in scales of 10 for seconds (ms, μs, ns). And long ones can be too.

The second is one of the 7 fundamental units

fibers carry light particles I guess

You would need to keep track of how high airplanes fly if you did argue semantics

Elevators don't travel any distance so if anyone is hurt by one they immediately lose by your metrics
