6 FAQs about [Battery cell weightlessness concept]
Why are car batteries weightless?
Unlike a conventional battery pack embedded in the chassis, these structural batteries are invisible. The electrical storage happens in the thin layers of composite materials that make up the car’s frame. In a sense, they’re weightless because the car is the battery. “It’s making the material do two things simultaneously,” says Greenhalgh.
Could a new structural battery reduce the weight of electronic devices?
Credit: Chalmers University of Technology | Henrik Sandsjö A new structural battery by Chalmers University could drastically reduce the weight of electronic devices and vehicles by combining load-bearing and energy storage capabilities, offering a leap in efficiency and design potential.
Can a structural battery cell carry more weight than aluminum?
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.
Can a lithium-ion battery increase stiffness and energy density?
Since then, the research group has further developed its concept to increase both stiffness and energy density. The previous milestone was reached in 2021 when the battery had an energy density of 24 watt-hours per kilogram (Wh/kg), which means roughly 20 percent capacity of a comparable lithium-ion battery. Now it’s up to 30 Wh/kg.
