Nanodiamonds Found to Prevent Lithium Battery Fires

Our work on nanodiamond additive suppressing lithium dendrites keeps attracting attention of news media. This article titled “Nanodiamonds Found to Prevent Lithium Battery Fires” was published in EE Times this week.

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.

2017 Energy Storage Materials Award

Professor Yury Gogotsi has won the 2017 Energy Storage Materials Award, which is awarded by the journal Energy Storage Materials. The Award will be presented to Professor Gogotsi at the ICEnSM 2017 (2017 International Conference on Energy Storage Materials), which will be held in Shenzhen, China, on Nov. 18-21, 2017. The award, which is sponsored by Elsevier, gives special recognition to a person who has accomplished outstanding achievements in energy storage materials and devices.

Just Squeeze In — Drexel Researchers Discover When Spaces Are Tight, Nature Loosens Its Laws

It turns out that when they’re in a hurry and space is limited, ions, like people, will find a way to cram in — even if that means defying nature’s norms. Recently published research from an international team of scientists, including Drexel University’s Yury Gogotsi, PhD, shows that the charged particles will actually forgo their “opposites attract” behavior, called Coulombic ordering, when confined in the tiny pores of a nanomaterial. This discovery could be a pivotal development for energy storage, water treatment and alternative energy production technologies, which all involve ions packing into nanoporous materials.

In their paper, which was recently published in the journal Nature Materials, the researchers explain how Coulombic ordering in liquid salts starts to break down when ions are confined in small spaces — specifically carbon pores less than a nanometer in diameter. And the narrower the pore, the less the ions adhere to Coulombic ordering. Read the full press release here.

Recipe for Safer Batteries — Just Add Diamonds

While lithium-ion batteries, widely used in mobile devices from cell phones to laptops, have one of the longest lifespans of commercial batteries today, they also have been behind a number of recent meltdowns and fires due to short-circuiting in mobile devices. In hopes of preventing more of these hazardous malfunctions researchers at Drexel University have developed a recipe that can turn electrolyte solution — a key component of most batteries — into a safeguard against the chemical process that leads to battery-related disasters.

Yury Gogotsi, PhD, Distinguished University and Bach professor in the College of Engineering, and his research team from the Department of Materials Science and Engineering, recently published their work — entitled “Nanodiamonds Suppress Growth of Lithium Dendrites” — in the journal Nature Communications. In it, they describe a process by which nanodiamonds — tiny diamond particles 10,000 times smaller than the diameter of a hair — curtail the electrochemical deposition, called plating, that can lead to hazardous short-circuiting of lithium ion batteries.
