■ Release Date: 2023.5.22

■ Published by: University of Technology Sydney

■ Keywords: hydrogen, renewable energy, fuel

■ Abstract:

A team of researchers has created a new supply chain model which could empower the international hydrogen renewable energy industry.

Headline: New invention: The oxygen-ion battery

■ Release Date: 2023.5.22

■ Published by: Vienna University of Technology

■ Keywords: ceramic, oxygen-ion-battery, energy storage

■ Abstract:

An oxygen-ion-battery has been invented, based on ceramic materials. If it degrades, it can be regenerated, therefore it potentially has an extremely long lifespan. Also, it does not require any rare elements and it is incombustible. For large energy storage systems, this could be an optimal solution.

Headline: Calcium rechargeable battery with long cycle life

■ Release Date: 2023.5.23

■ Published by: Tohoku University

■ Keywords: calcium, battery, lithium-ion

■ Abstract:

With the use of electric vehicles and grid-scale energy storage systems on the rise, the need to explore alternatives to lithium-ion batteries has never been greater. Researchers have recently developed a prototype calcium metal rechargeable battery capable of 500 cycles of repeated charge-discharge -- the benchmark for practical use. The breakthrough was made thanks to the development of a copper sulfide nanoparticle/carbon composite cathode and a hydride-based electrolyte.

Headline: Flexing crystalline structures provide path to a solid energy future

■ Release Date: 2023.5.23

■ Published by: Duke University

■ Keywords: battery, energy storage, argyrodites

■ Abstract:

Researchers have uncovered the atomic mechanisms that make a class of compounds called argyrodites attractive candidates for both solid-state battery electrolytes and thermoelectric energy converters. The discoveries -- and the machine learning approach used to make them -- could help usher in a new era of energy storage for applications such as household battery walls and fast-charging electric vehicles.

Headline: Engineers harvest abundant clean energy from thin air, 24/7

■ Release Date: 2023.5.24

■ Published by: University of Massachusetts Amherst

■ Keywords: electricity, clean energy, battery

■ Abstract:

A team of engineers has recently shown that nearly any material can be turned into a device that continuously harvests electricity from humidity in the air. Researchers describe the 'generic Air-gen effect'-- nearly any material can be engineered with nanopores to harvest, cost effective, scalable, interruption-free electricity. The secret lies in being able to pepper the material with nanopores less than 100 nanometers in diameter.

Headline: Twisting under the stroboscope -- Controlling crystal lattices of hybrid solar cell materials with terahertz light

■ Release Date: 2023.5.25

■ Published by: Fritz Haber Institute of the Max Planck Society

■ Keywords: solar cell, lead, perovskite

■ Abstract:

To overcome global energy challenges and fight the looming environmental crisis, researchers around the world investigate new materials for converting sunlight into electricity. Some of the most promising candidates for high-efficiency low-cost solar cell applications are based on lead halide perovskite (LHP) semiconductors. Despite record-breaking solar cell prototypes, the microscopic origin of the surprisingly excellent optoelectronic performance of this material class is still not completely understood. Now, an international team of physicists and chemists has demonstrated laser-driven control of fundamental motions of the LHP atomic lattice.

Headline: Absolute vs. relative efficiency: How efficient are blue LEDs, actually?

■ Release Date: 2023.5.26

■ Published by: Beckman Institute for Advanced Science and Technology

■ Keywords: indium, gallium, light-emitting diodes

■ Abstract:

The absolute internal quantum efficiency (IQE) of indium gallium nitride (InGaN) based blue light-emitting diodes (LEDs) at low temperatures is often assumed to be 100%. However, a new study has found that the assumption of always perfect IQE is wrong: the IQE of an LED can be as low as 27.5%.
