New carbon-stabilized Li-Si anodes for all-solid-state Li-ion batteries
All-solid-state batteries (ASSBs)—battery technologies with solid electrodes and solid electrolytes—have become the focus in an increasing number of research studies. This is primarily because they could significantly outperform batteries with liquid or polymer-based...
A strategy to reduce defects in inverted perovskite solar cells and improve their performance
Perovskites, a class of materials with a characteristic crystal structure, have proved to be very promising for the fabrication of solar cells and photovoltaics. One of these materials is lead triodide (FAPbI3), a perovskite that exhibits a long carrier lifetime and a...
A strategy to create highly performing cobalt-free cathodes for lithium-ion batteries
Lithium-ion (Li-ion) batteries, rechargeable batteries that can store energy via the reversible reduction of lithium ions, are among the most widespread battery technologies, due to their remarkable performance and extended life cycle. Many existing and emerging...
Grooved electrodes could improve the performance of proton-exchange membrane fuel cells
Proton-exchange membrane fuel cells (PEMFCs) are a promising energy solution for reducing carbon emissions in the transport sector. As suggested by their name, these cells contain a proton-conducting membrane based on polymer materials that serves as an electrolyte....
A strategy to induce the formation of a stable salt-derived solid electrolyte interphase in lithium metal batteries
Lithium metal batteries are promising battery solutions that use metallic lithium as an anode. Instead of containing electrode materials that store lithium ions, like commonly employed lithium-ion batteries (LiBs), they use a single layer of lithium near the anode,...
New design strategies to improve the stability and efficiency of bifacial perovskite solar cells
Solar cells based on perovskites, calcium titanium oxide minerals or compounds with similar structures, are among the most promising emerging energy solutions. Over the past few years, engineers and material scientists have been exploring the potential of solar...
New hybrid photocatalysts for water splitting with an internal quantum efficiency above 100%
As hydrogen inside fuel cells can generate electrical power, scalable methods to reliably split water into hydrogen and oxygen could have valuable implications for the energy industry. These methods could help to produce large amounts of hydrogen for more sustainable...
New inorganic wide-bandgap perovskite subcells that are both efficient and stable
All-perovskite tandem solar cells, stacks of p-n junctions formed from perovskites with different energy bandgaps, have the potential of achieving higher efficiencies than conventional single-junction solar cells. So far, however, most proposed all-perovskite tandem...
Study defines a crucial parameter for the suppression of lithium dendrites in all-solid-state LiBs
All-solid-state lithium batteries (ASSLiBs), lithium batteries with solid electrolytes, are highly promising battery solutions, as they are often more stable than cells based on liquid electrolytes and have a higher capacity. However, the deposition of lithium inside...
