A groundbreaking advancement in structural battery technology promises to create lighter and more efficient vehicles and devices.

Scientists at Oak Ridge National Laboratory have developed a solid-state battery that could potentially double the energy density in electric vehicles, enhancing their range significantly.

To facilitate commercialization, Chalmers University has launched a spin-off company, Sinonus AB, aimed at moving from lab-scale production to large-scale manufacturing of these structural batteries.

Calculations indicate that electric cars equipped with these innovative structural batteries could achieve driving ranges up to 70% longer than current models.

Led by Professor Leif Asp, the research team has successfully increased the stiffness of the battery cells, making them as strong as aluminum while remaining lightweight.

This new technology integrates energy storage directly into the material's structure, functioning similarly to a human skeleton by providing both support and energy storage.

The use of a semi-solid electrolyte in the battery enhances safety by reducing fire risks associated with traditional liquid electrolytes.

Despite the promising advancements, challenges such as scaling production and improving energy density remain, but there is optimism about the technology's future impact.

The new battery design separates the positive and negative electrodes to prevent short circuits and utilizes sulfide solid-state electrolytes, offering performance comparable to liquid electrolytes.

Professor Asp emphasizes the critical need for investment in light and energy-efficient vehicles to ensure sustainability for future generations.

The research was supported by the Wallenberg Initiative Materials Science for Sustainability programme, highlighting a significant commitment to sustainable technology development.

Current lithium-ion batteries pose fire risks and can release hazardous chemicals, while the new structural battery technology aims to mitigate these dangers.
