A team of scientists at Argonne National Laboratory has developed a powerful technique for probing in three dimensions the crystalline structure of cathode materials at the nanoscale inside a battery. In particular, the technique probes what happens during the process of "intercalation" — the insertion of ions between the layers of a cathode when a battery generates electricity.
