Lithium-ion
batteries have become an indispensable power source for our
proliferating gadgets. They have also, on occasion, been known to catch
fire. To yield insight into what goes wrong when batteries fail and how
to address the safety hazard, scientists report that they have found a
potential way to track lithium ions as they travel in a battery.
In essence, rechargeable batteries
work by shuttling ions back and forth between electrodes through an
electrolyte. Often, failure occurs when lithium ions stray from their
intended path. To better understand how this happens, scientists have
looked for ways to track the ions. Several methods have been proposed,
but so far, they have been limited for various reasons, including poor
spatial resolution. Fluorescence microscopy, which is often used to
probe materials and biological systems, could potentially fill this
void. But first, scientists would need to find a fluorescent label that
is sensitive to lithium ions. Randall H. Goldsmith and colleagues at the
University of Wisconsin-Madison set out to do this.
The researchers worked with 2-(2-hydroxyphenyl)naphthoxazole, or HPNO, a molecule that fluoresces when it attaches to lithium ions. They added a "visible pump" to help prevent photobleaching and other damage. In a battery-like environment, the system could image and track lithium ions. The researchers note that their next step would be to test the molecule in a more realistic analog of a battery cell.
