Nanodiamonds May Make Lithium Batteries Safer

In the A.J. Drexel Nanomaterials Institute, diamonds are not just for jewelry and drill bits.

According to Drexel University professor Yury Gogotsi and his team of researchers, diamonds — nanodiamonds, specifically — might just be the key to making certain types of batteries more energy efficient.

When a person thinks of rechargeable batteries, they are likely picturing lithium ion batteries, which power most portable devices such as cell phones and laptops. They generate energy by transferring ions of a lightweight metal called lithium back and forth between the two ends, or electrodes, of the battery. One of these electrodes is made of a carbon-based compound called graphite, which serves as a host for the lithium. Read the full article here.
