    New Carbon Fiber Batteries Could Form the Actual Framework of Cars and Airplanes

    Cars and planes could soon be built from the world’s strongest batteries, thanks to a ground-breaking innovation from Chalmers University of Technology in Sweden.

    Researchers detailed the advance of so-called massless energy storage—and a structural battery that could cut the weight of a laptop by 50%, make mobile phones as thin as a credit card, or increase the driving range of an EV by up to 70 percent on a single charge.

    Structural batteries are materials that, in addition to storing energy, can carry loads. Stiff, strong carbon fibers could store electrical energy chemically and, in this way, the battery material can become part of the actual construction material of a product.

    And, when cars, planes, ships, or computers are built from a material that functions as both a battery and a load-bearing structure, the weight and energy consumption are radically reduced.

    “We have succeeded in creating a battery made of carbon fibre composite that is as stiff as aluminum and energy-dense enough to be used commercially,” says Chalmers researcher Richa Chaudhary, the first author of a paper recently published in Advanced Materials. “Just like a human skeleton, the battery has several functions at the same time.”

    When it comes to vehicles 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. This means that the material can carry loads just as well as aluminum, 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,” said research leader Leif Asp, professor at the Department of Industrial and Materials Science at Chalmers.

    “Investing in light, energy-efficient vehicles is a matter of course if we are to economize on energy and think about future generations. We have made calculations on electric cars that show that they could drive for up to 70 percent longer than today if they had competitive structural batteries.”

    The team said the goal was always to achieve a performance that makes it possible to commercialize the technology. The link to the market has been forged through the newly started Chalmers Venture company called Sinonus. And, they’ve received “a great deal of interest from the automotive and aerospace industries”.

    However, there is still a lot of engineering work to be done before the battery cells have taken the step from lab manufacturing on a small scale to being produced on a large scale for our vehicles.

    “It will require large investments to meet the transport industry’s challenging energy needs, but this is also where the technology could make the most difference,” added Professor Asp.
