(PhysOrg.com) -- It turns out you can be too thin -- especially if you're a nanoscale battery. Researchers from the National Institute of Standards and Technology, the University of Maryland, College Park, and Sandia National Laboratories built a series of nanowire batteries to demonstrate that the thickness of the electrolyte layer can dramatically affect the performance of the battery, effectively setting a lower limit to the size of the tiny power sources. The results are important because battery size and performance are key to the development of autonomous MEMS—microelectromechanical machines—which have potentially revolutionary applications in a wide range of fields.
