Accelerating demand for renewable energy and electric vehicles is sparking a high demand for the batteries that store generated energy and power engines. But the batteries behind these sustainability solutions aren’t always sustainable themselves. In a paper publishing September 1 in the journal Matter, scientists create a zinc battery with a biodegradable electrolyte from an unexpected source—crab shells.

:p
Best!! Thanks
I just used some minutes ago
1,000 cycles does not seem like much to me.
Make that at least 100,000 and I may begin to be interested.
For a cell phone, that’s almost three years. Most cell phones are probably only able to recharge half its potential in three years.
If they combine this with a battery Instead about that was made out of common materials, you may have something that is worth looking at.

It’s got Electrolytes!
The weather!
A little warm for pocket carry? :)
Maybe able to bolster the heater in an EV?
“They can not only operate at high temperatures of up to 200 °C (392 °F) but they actually work better when hotter – at 110 °C (230 °F), the batteries charged 25 times faster than they did at 25 °C (77 °F)”.
Would that be too warm for an E-car battery?
Still much cooler than Li batteries when they catch fire. :)
A clever engineer would find ways to capitalize on that heat, as I mentioned it might be useful to supplement heating the interior in winter.
Pipe water around it for the on-board espresso machine?
Or more seriously, use the heat to drive the AC in summer.
Should not be a major barrier to EV use so long as it is not rushed into production like a certain vaccine.
