Key Highlights
•
Researchers have developed a new type of zinc-iodine battery that works without a physical separator, which is a component that usually keeps the battery’s parts from touching but also slows down energy flow. This breakthrough allows the battery to store more energy in a smaller space while preventing the chemical “shuttle” effect that normally degrades its performance, paving the way for more compact and efficient energy storage.

A new material designed with stacked layers of porous and non-porous carbon sheets loaded with cobalt nanoparticles achieves record-breaking absorption of electromagnetic waves. This structure creates multiple points of energy conversion, allowing it to effectively convert unwanted electromagnetic energy into heat across a very wide range of frequencies, which is crucial for improving electronic shielding and energy efficiency.

A lab-scale study of a single-well geothermal system has identified the optimal conditions for pulling heat from the ground, finding that a specific flow rate, injection temperature, and spacing between wells provides the best balance of high heat output and stable operation. This work provides a practical blueprint for designing more efficient and sustainable geothermal energy systems that can provide consistent, clean heat.
