Lithium-ion batteries impressed by kids’s slime will not catch hearth and explode


The slimy kids’s goo often known as oobleck, constituted of cornstarch and water, has impressed researchers to create a lithium-ion battery that’s much less susceptible to harmful fires.

Lithium-ion batteries are indispensable to our tech-filled lives — they energy principally all of our digital units, from laptops to headphones to smartphones. Sadly, they can explode when broken (as one main cell producer is well aware).

A lithium-ion battery has two electrodes which are by no means meant to return involved with one another. Most units use a separating layer of plastic to stop this from occurring. Nonetheless, if that plastic turns into broken or the electrodes are bent in such a approach that they’ll contact…


On Wednesday, researchers introduced another, cheap methodology to stop these fires from occurring on the 256th Nationwide Assembly & Exposition of the American Chemical Society — and revealed they had been impressed by the properties of oobleck.

Gabriel Veith, the venture’s principal investigator, defined that his concept was born when he noticed his youngsters enjoying with oobleck. Oobleck, which is named after a Dr. Seuss book, acts very similar to a liquid till it’s touched. Should you transfer it or attempt to hit it, it acts extra like a stable.

Utilizing that philosophy, Veith and colleagues suspended silica particles in a liquid and added them to the batteries, giving them comparable traits to the slime. When the batteries are impacted, the silica particles clot collectively and harden, stopping the stream of fluids or ions. Which means no extra fires.

The crew patented the know-how below the identify ‘Secure Affect Resistant Electrolyte’, reports Science. Sooner or later, Veith hopes to enhance the system and apply it to batteries in drones and finally within the armed forces, the place troopers usually carry heavy batteries on their particular person.
