Power/Performance Bits: Feb. 23


Apple core batteries Apple waste could help reduce the cost of energy storage, say researchers seeking an improved sodium-ion at the Helmholtz Institute Ulm of Karlsruhe Institute of Technology. Sodium-ion batteries are not only far more powerful than nickel-metal hydride or lead acid accumulators, but also represent an alternative to lithium-ion technology, as the initial materials neede... » read more

Insect robots on the water Taking inspiration from water beetles and other swimming insects, academics at the Bristol Robotics Laboratory have developed the "Row-bot," a robot that thrives in dirty water. The Row-bot mimics the way that one aquatic insect, the water boatman, moves and the way that it feeds on rich organic matter in the dirty water it swims in. The Row-bot project aims to ... » read more

Single material batteries Engineers at the University of Maryland created a battery made entirely out of a single material that, by incorporating the properties of both the electrodes and electrolyte, can both move electricity and store it. The reason the new battery is revolutionary is because it solves the problem of what happens at the interface between the electrolyte and the electrod... » read more

What can snails teach us about creating batteries? Evgenia Barannikova, a graduate student at University of Maryland, Baltimore County presented the current state of research in using biology to improve the properties of lithium ion batteries at the 59th annual meeting of the Biophysical Society, held Feb. 7-11 in Baltimore, Maryland. One of the inspirations for her research was the way t... » read more
