Efficient and cheap batteries that can also capture harmful emissions could be right around the corner, thanks to a new system that speeds up the development of catalysts for lithium-CO₂(Li-CO₂) batteries.

The technology has been developed by the University of Surrey, Imperial College London, and Peking University to address the slow and inefficient methods currently used to produce catalysts for Li-CO₂batteries.

In the study, researchers used their tool to test and screen materials like platinum, gold, silver, copper, iron and nickel to easily investigate whether they would be suitable candidates for developing high-performing Li-CO₂batteries.

Dr Kai Yang, corresponding author of this work, project co-leader and Lecturer from the Advanced Technology Institute at the University of Surrey, explained:

"We have created a cutting-edge lab-on-a-chip electrochemical testing platform that can do multiple things at the same time. It helps evaluate electrocatalysts, optimise operation conditions, and study CO₂conversion in high-performance lithium-CO₂batteries. This new method is more cost-effective, efficient, and controllable than traditional ways of making these materials."

Li-CO₂batteries are a promising new type of battery that work by combining lithium and carbon dioxide; they not only store energy effectively but also offer a way to capture CO₂, potentially making a dual-contribution to the fight against climate change.

Dr Yunlong Zhao, the lead corresponding author of this study and a Senior Lecturer at Imperial College London, the National Physical Laboratory, and visiting academic from the University of Surrey, said:

“这是我们开发新的负面emissi至关重要ons technologies. Our lab-on-a-chip platform will play a crucial role in advancing this goal. It will not only enhance our understanding of novel batteries, but it can also be applied to other systems like metal-air batteries, fuel cells, and photoelectrochemical cells.

"This new tool will enable quick screening of catalysts, studying reaction mechanisms, and practical applications, from nanoscience to cutting-edge carbon removal technologies."
