You’re right, the current sulfuric acid and potassium hydroxide we use right now are just flowers are roses compared to… water
You’re worried about the amount of liquid present in a battery that fits on a motherboard? Or are you talking about laptop batteries?
The last time something like this was posted (by a less reputable source admittedly) I was hopeful and defensive. From what I’ve read since then, essentially, show me the battery.
The managing director of Deakin University’s Battery Research and Innovation Hub, Dr Timothy Khoo, who was not involved in the research, said he was sceptical about any claims water batteries may one day replace lithium-ion, but said the protective layer developed by the RMIT-led team represents a “novel and quite unique” approach that solves “a key stability issue” with battery technology.
Pretty much my thoughts exactly when I read the article. The lead researcher of this project is bigging it up well beyond any rational scope, but they do have a novel invention here for dealing with dendrites in batteries.
Perhaps their technique could be applied to more conventional batteries, though I’m somewhat doubtful. Bismuth isn’t exactly cheap, which is why lead acid dominates for most things.
Finally! Are these ones I can swallow?
Seems like Gatorade, a water based electrolyte, instead of an acid based electrolyte. It’s mostly about less toxic and cheaper which are pluses, but nothing really about how well they work
but nothing really about how well they work
There was a brief mention in the article about how they used a bismuth oxide layer to prevent dendrites from forming, that’s novel and cool. However I think the bigger issue is material cost - bismuth costs much more than lead acid.
