‘Nano-shish-kebabs’ are a recipe for better lithium-ion batteries

Powerful energy storage devices of the future may trace their roots back to a research lab that cooked up “nano-shish-kebabs” out of germanium sulfide, a semiconductor material.

Unlike the skewered meats and assorted veggies grilled on backyard barbeques, these kebabs are single, three-dimensional structures that consist of sheets of the semiconductor material grown along a nanowire. Each wire is about 100 nanometers long.
