Lithium-ion batteries that don't explode...

... a step closer with new water-based technology

Exploding lithium-ion batteries may soon be a thing of the past with the development of a safer, lighter version that matches the power level needed to run everyday devices.

Lithium-ion rechargeable batteries, which are found in smartphones, e-cigarettes, hoverboards and electric vehicles, earned their reputation for volatility after a series of high-profile explosive failures that led to the recall of Samsung's Galaxy Note 7 smartphone.
The main problem with existing lithium-ion batteries is the conducting liquid — through which ions are exchanged between positive and negative electrodes — is flammable. So, if the battery overheats or shorts out, there's a risk the liquid can ignite.

Now a team of researchers from the University of Maryland and the US Army Research Laboratory have found a way around this, by developing a battery that contains a water-based salt solution instead of a flammable liquid.

The PBS TV show Nova here in the US aired an episode on various forms of energy storage, including a segment The Battery That Refuses to Explode https://www.youtube.com/watch?v=m9-cNNYb1Ik which features Mike Zimmerman at Tufts University that has designed a lithium ion battery with a solid polymer serving as the electrolyte. He apparently has founded a company named Ionic Materials to commercialize it. It's pretty impressive, but I don't know about the relative costs and efficiency tradeoffs of various alternatives.

Boffins develop lithium-ion batteries that can't catch fire

Boffins have developed what they claim is a potential solution to stop lithium-ion device batteries, such as those found in smartphones, from combusting.

However, after studying practical and inexpensive ways to help prevent device battery fires, scientists from the Oak Ridge National Laboratory and the University of Rochester claim to have devised a solution.

[...] the researchers mixed an additive into the conventional electrolyte to create an impact-resistant electrolyte.
According to Veith, this solidifies on impact and prevents the electrodes from touching if the battery is damaged during a fall or crash. Put simply, if the electrodes don't touch each other, the battery shouldn't catch fire.

Thanks for a link to that Documentary episode of these.

In my work travels while transporting loads of these as a hauler, I never experienced a defect in transit but always wondered how volatile a bulk cargo bunch of those was since they were highly decorated with all sorts of warnings and I had to sign off on a Tip and Tell agreement if they got shifted beyond a certain predetermined threshold. Loved my work being the industrial head I always have been.
