New Li-Ion Technology Charges 10x Faster, Holds 10x More

graphene

Inside Li-ion there are innumerable layers of graphene, a one-atom-thick sheet of carbon atoms. Lithium ions fill the spaces between these layers and when the bettery is being charged the atoms make their way to the edge of the sheet in order to get down to the next layer and make room for more ions. The speed of recharging is limited by how quickly these ions can get from layer to layer.

Researchers from Northwestern University and the University of Illinois at Urbana-Champaign have developed a camera based on the human eye. The researchers boast of the eye camera’s superiority over human eyes – it can zoom. While it only has a 3.5x optical zoom, the researchers said a higher zoom will come as the technology advances.

Researchers at Northwestern’s McCormick School of Engineering and Applied Science have made a robotic fish that can swim in all directions. The robot, nicknamed Ghostbot, was inspired by the Black Ghost Knifefish that lives in the Amazon basin; a nocturnal fish that has poor eyesight and relies on a weak electric field to hunt for food. It can move both vertically and horizontally using either one or two waves alongside its single long fin.
