Electric vehicles get major boost from new ultra-powerful lightweight battery
- Structural batteries merge energy storage with load-bearing capabilities, revolutionizing material science in electric vehicles and gadgets.
- These batteries integrated into the structure eliminate the need for separate support systems, reducing weight and enhancing performance.
- By using advanced materials like carbon fibers, researchers achieve a balance between strength and electrochemical properties.
- Innovations include carbon fibers as anode or cathode, leading to improved energy densities and mechanical robustness.
- Carbon fiber composite batteries offer energy densities comparable to aluminum but at a fraction of the weight.
- Chalmers University of Technology leads in structural battery research, aiming for a 70% boost in energy efficiency for electric cars.
- Commercialization efforts are underway, with applications expected in portable electronics, aerospace, and automotive industries.
- Challenges like transitioning to semi-solid electrolytes for better safety and power densities need to be addressed for wider adoption.
- Structural batteries offer environmental benefits by reducing material usage and eliminating conflict metals like cobalt.
- Future directions involve overcoming limitations of liquid electrolytes and maximizing the potential of all-carbon-fiber structural batteries.
