Could the World's Strongest battery help build credit-card-thin mobile phones?

The world’s strongest battery, developed by researchers at the Chalmers University of Technology in Sweden, is paving the way for massless energy storage that could help build credit-card-thin mobile phones or even increase the range of electric vehicles by as much as 70 percent, a press release said.

How strong is a battery cell?

When it comes to vehicles, of course, there are high demands on the design to be sufficiently strong to meet safety requirements. There, the research team's structural battery cell has significantly increased its stiffness, or more specifically, the elastic modulus, which is measured in gigapascal (GPa), from 25 to 70.

Are batteries the 'best battery chemistry'?

Batteries are everywhere. They’re in a seemingly endless number of devices we use, from cell phones, remotes, Bluetooth speakers, golf carts and the growing category of LSEVs. While batteries are nothing new, advancements and the race for the “best battery chemistry” is as ferocious as ever.

Are structural batteries better than aluminium?

This means that the material can carry loads just as well as aluminium, but with a lower weight. "In terms of multifunctional properties, the new battery is twice as good as its predecessor – and actually the best ever made in the world," says Leif Asp, who has been researching structural batteries since 2007.

Are structural batteries a good solution?

Structural batteries are a possible solution to the problem since they shoulder load-bearing functions in a device and are no longer deadweights that must be carried around. In the case of a vehicle, this also reduces energy consumption, which translates into a higher range.

Which metal-air battery is the most attractive?

I'm glad it was mentioned as I hadn't thought of it. "Of the various metal-air battery chemical couples (Table 1), the Li-air battery is the most attractive since the cell discharge reaction between Li and oxygen to yield Li2O, according to 4Li + O2 → 2Li2O, has an open-circuit voltage of 2.91 V and a theoretical specific energy of 5210 Wh/kg.
