I don't know about this. Countless times researchers discover the next battery so much better than the current state-of-the-art being deployed, only to find out they just can't scale it. New battery technology is really hard.
I wonder how safe this will be with hydrogen gas being a part of it. Sounds promising but you’d want it extra safe considering a mini Hindenburg would be attached to your house. Edit. I suppose I read it incorrectly as this is being invented for the utility scale.
With adequate seals this is no more dangerous than existing chemical energy storage, such as gasoline and natural gas. The researchers state (in the paper itself) that they carefully control the charging voltage to avoid oxygen production in the same cell. Oxygen and hydrogen in the same device is dangerous, only hydrogen not so much.
Unfortunately, history shows that new battery chemistries are a dime a dozen. It's commercialization and manufacturing at scale that's the real bottleneck. Look at what happened to Aquion, which raised $190 million for their salt water battery: https://www.greentechmedia.com/articles/read/Aquion-the-Bill...
>Cui estimated that, given the water-based battery’s expected lifespan, it would cost a penny to store enough electricity to power a 100-watt lightbulb for twelve hours. Oh dear, I hate university news "journalism" with a passion. For the life of me I cannot understand why they feel the need to dumb down parts of the content while other parts remain decidedly technical. Is it to have something that laymen can quote?…
I've often criticized people for ignoring the cost of storage when talking about wind/solar prices, but at a penny per kWh it's pretty insignificant.
Could someone ELI5 how the recharge cycle works? On charging it evolves H2 gas; how does that get put back on recharge? This is very much NOT explained by the paragraph, > The researchers did this by re-attaching their power source to the depleted prototype, this time with the goal of inducing the manganese dioxide particles clinging to the electrode to combine with water, replenishing the manganese sulfate salt. Onc…
The work sounds interesting, but the article is painfully written.
Lead acid batteries produce hydrogen too. I think the insight is that this can’t produce electricity directly, so the chemistry can be much more stable.

Uh, doesn't hydrogen have a history of leaking through most materials due to its small atomic size?

Ouch. And they later sold for $9.2 million. I sure have some questions about what they spent the money on.
