Lithium-ion

Lithium-ion batteries degrade over time, but there are ways you can make them last longer. A team at the University of Michigan, Ann Arbor, has put together a list of best practices to preserve the life of lithium-ion batteries as long as possible.

In a quest for safer lithium-ion batteries, a team of engineers at the University of Illinois have come up with a solid polymer-based electrolyte that can not only heal itself but is recyclable without the need for high temperatures or strong acids.

Researchers at Australia's Deakin University say they've managed to use common industrial polymers to create solid electrolytes, opening the door to double-density solid state lithium batteries that won't explode or catch fire if they overheat.

The 2019 Nobel Prize in Chemistry has been awarded to three scientists for the invention and development of the lithium-ion battery.

Batteries have become much more efficient, but gauging their service life is still extremely difficult and time-consuming. To better predict how long a battery will last, MIT and Toyota have teamed up to employ artificial intelligence to accurately determine battery life without years of testing.

Engineers have developed a new type of hybrid cathode for a lithium-sulfur battery that seems to boast better energy density than existing versions of both lithium-ion and lithium-sulfur batteries.

It what seems like a paradox, engineers have been blowing up batteries in hopes of cleaning up space debris. In a series of severe "abuse" tests at the test bunkers of France’s CEA, lithium-ion batteries were tortured to better understand catastrophic battery failures and prevent battery explosions.

A new study shows how fluoride might be put to work in better batteries. Researchers at Caltech, JPL, Lawrence Berkeley National Lab and the Honda Research Institute have developed fluoride-based batteries that could potentially last much longer than existing lithium-ion-based devices.

Scientists have come up with a way to stop damaged lithium-ion batteries catching fire. The batteries effectively harden on impact, preventing the electrodes making contact and starting a fire.

​​So much of focus from researchers in lithium battery circles rests centers on the electrodes. Among them are scientists at Carnegie Mellon University, who have come up with a new way of 3D printing latticed electrodes they say result in an "unprecedented improvement."​

Researchers have found that materials known as niobium tungsten oxides form microscopic structures that let lithium ions flow through them at much greater rates than current technology allows. The finding could be the key to building safe lithium-ion cells that charge in minutes rather than hours.

Striking a balance between common materials and efficiency is important for batteries, and regular old salt looks like it could fit the bill – after a few kinks are ironed out. Now, KAUST researchers have developed a way to make disordered graphene that can improve the sodium-ion battery recipe.
