Abstract

original image

A high-throughput optical screen designed to reduce costs and accelerate the screening of libraries of electroactive materials, in particular fuel-cell electrocatalysts and battery materials, is presented. The methodology uses an electrochromic film as a counter electrode, and makes use of spatially varying color change across this screening counter electrode as differing amounts of charge are passed across the array during a test reaction (see figure).
