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.

Entering the Fast Lane — MXene Electrodes Push Charging Rate Limits in Energy Storage

Can you imagine fully charging your cell phone in just a few seconds? Researchers in Drexel University’s College of Engineering can, and they took a big step toward making it a reality with their recent work unveiling of a new battery electrode design in the journal Nature Energy.

The team, led by Yury Gogotsi, PhD,Distinguished University and Bach professor in Drexel’s College of Engineering, in the Department of Materials Science and Engineering, created the new electrode designs from a highly conductive, two-dimensional material called MXene. Their design could make energy storage devices like batteries, viewed as the plodding tanker truck of energy storage technology, just as fast as the speedy supercapacitors that are used to provide energy in a pinch — often as a battery back-up or to provide quick bursts of energy for things like camera flashes.
