How will battery technology impact the future of EVs?

Projections are that more than 60% of all vehicles sold by 2030 will be EVs, and battery technology is instrumental in supporting that growth. Batteries also play a vital role in enhancing power-grid resilience by providing backup power during outages and improving stability in the face of intermittent solar or wind generation.

When will CATL's second-generation sodium battery be released?

On November 18, CATL announced its second-generation sodium battery. Addressing the World Young Scientists Summit, chief scientist Wu Kai said the new battery will be launched next year – four years after the release of CATL’s first sodium-ion battery in 2021.

How can lithium-sulfur chemistry unlock the potential of solid-state battery technology?

Collaboration across industries along with ongoing research and development efforts will be vital for unlocking the full potential of solid-state battery technology. With its promise of unprecedented energy density, lithium-sulfur chemistry stands at the threshold of transformative applications.

How does a solid state battery work?

But, in a solid state battery, the ions on the surface of the silicon are constricted and undergo the dynamic process of lithiation to form lithium metal plating around the core of silicon. “In our design, lithium metal gets wrapped around the silicon particle, like a hard chocolate shell around a hazelnut core in a chocolate truffle,” said Li.

What is a solid-state battery?

Solid-state batteries (Figure 1A) are a new type of battery technology that aims to overcome the safety concerns associated with traditional batteries that use liquid electrolytes (Janek and Zeier, 2023). They offer higher energy density, which is a significant advantage.

Will AI and supercomputing help battery researchers predict new high-performing materials?

"AI and supercomputing will become crucial tools for battery researchers in the upcoming years to help predict new high-performing materials," she said. But Dr Edward Brightman, lecturer in chemical engineering at the University of Strathclyde, said the tech would need to be "treated with a bit of caution".
