Abstract

original image

Elements with potential: A silicon–air battery using an alkaline solution as electrolyte is comprised of only environmentally friendly and widely available elements, including silicon, potassium, oxygen, and hydrogen. The assembled battery exhibits an average working potential between 0.9 to 1.2 V at variable discharge current densities, and high specific capacities are achieved.
