Fuels synthesized using sunlight offer a sustainable solution for chemical energy storage, but inefficient utilization of the solar spectrum has limited their broader viability. This Review looks at how approaches that are complementary to one another can be employed to better exploit solar energy for sunlight-to-fuel conversion.
Irreversibility is one of the biggest obstacles in realizing practical Li-metal batteries. This Review surveys the trends in Coulombic efficiency (CE)—a reversibility indicator—reported for Li-metal batteries over the last five decades, abstracts key CE descriptors and analyses promising strategies to improve CE.
The energy-saving impact of energy-efficient technologies can be diminished by rebound resulting from post-adoption behaviour. This Review examines how behavioural regularities affect energy-relevant decisions and associated rebound effects
The promising performance of low-platinum-loading oxygen reduction reaction catalysts in preliminary electrochemical tests is rarely translated into similarly impressive performance in real fuel cells. In this Review, Li and colleagues explore the underlying reasons for this issue and outline strategies to overcome it.
Fuel cells are increasingly being considered for powertrains of heavy-duty transportation. Cullen et al. survey the technical challenges of fuel cells at both the system and materials level for transportation application and outline the roadmap for future development.
Carbon dioxide electroreduction is a promising approach to synthesize chemicals and fuels using renewable energy. This Review explores our understanding of anion exchange membranes — a key component of certain carbon dioxide electrolysers — and outlines approaches to design improved materials.
High-performance solid-state electrolytes are key to enabling solid-state batteries that hold great promise for future energy storage. The authors survey the fabrication process of thin-film versus thick oxide-based solid-state electrolytes and discuss their material design and processing options.
Tremendous research progress has been made in the development of post-lithium-ion batteries (PLIBs), yet there is little discussion on the manufacturing of these upcoming technologies. In this Review, the authors survey the current production status of several representative PLIBs and offer an industrial-scale manufacturing outlook.
