Charge less, power more: Zinc-bromine battery tech hits record 10,000 charge cycles

Summary

The novel electrodes prevent self-discharge and boost performance in flowless zinc-bromine batteries by stopping bromine crossover. It’s a nitrogen-doped mesoporous carbon-coated thick graphite felt (NMC/GF) electrode.

The research was published in the Chemical Engineering Journal. With safer, more stable, and longer-lasting FLZBBs on the horizon, the path to a clean and sustainable energy future seems a little brighter. The research waspublished in the chemical engineering journal.

Seems like these might have a smaller density than regular lithium-ion. Probably will be fine when weight and space aren't issue but not for things like electric vehicles.

What are the relative densities for each?

60 - 85 Wh/kg vs 200 - 300 Wh/kg, so much lower.

Then yea, that's not going to be good any time soon for consumer devices

Yea, I'm seeing this for a larger use case where we are doing large scale energy storage

I think with everything we've seen with performance, devs just take advantage of the new stuff to pack in more stuff and not actually let it improve quality

I think we're a ways off with the density difference the other comment mentioned
