A Billion-Hole Battery

Dean Sigler Electric Powerplants, Sustainable Aviation 0 Comments

Battery companies and academic researchers keep finding ways to make ions flow quickly and efficiently within batteries. One way is to reduce the size of a cell so that the ions don’t have to travel far.  University of Maryland researchers may have achieved a miniaturization that boggles the mind. Their claim, that they’ve created a “single tiny structure that includes all the components of a battery that they say could bring about the ultimate miniaturization of energy storage components, comes from a story by Martha Heil in UMD Right Now. The structure is based on a nanopore, an incredibly tiny hole in a ceramic sheet 80,000 times thinner than a human hair.  The holes can hold electrolyte that carries a …

Ohio State’s Solar-Air Potassium Battery

Ohio State University researchers have come up with a two-in-one solar cell/battery combination that promises great efficiency and low costs.  What’s not to like? Unfortunately for readers of the blog, it’s initially only a stationary system that will make energy storage a viable circumstance for large power plants, but it seems that the technology could be adapted to lighter, portable applications, such as electric vehicles. Ohio State is keeping somewhat mum about the patent-pending device, which they are developing as a commercial entity under the auspices of their spin-off, Kair (K for potassium, plus air and pronounced “care”).  We’ve heard a great deal about upcoming lithium-air batteries, but potassium-air is unique.  Even more unique, this battery stores energy from its …
