Nature Communications, Published online: 25 May 2026; doi:10.1038/s41467-026-72531-4 Direct recycling of spent lithium-ion batteries is a promising and essential approach to address challenges related to energy security and resource sustainability. Herein, authors report an upcycling strategy that reconstructs degraded ternary layered oxide cathode materials into Li-rich oxides. The strategy is s…

Every year, millions of lithium batteries travel across the world inside electric vehicles, e-bikes, power banks, laptops, and drones. Most of them arrive safely. But when a battery gets crushed — whether in a car accident, a shipping container, or even from being dropped or hit by something heavy — the situation can become dangerous very fast. This is why the UN38.3 crush test was created. UN38.…

Birmingham researchers have developed a new method for producing hydrogen fuel that costs less than existing approaches. Hydrogen has long been hailed as a key fuel for a low-carbon future, capable of powering everything from heavy industry to transportation without producing carbon emissions at the point of use. Yet there is a major contradiction at [...]

A breakthrough lithium-extraction method could help solve one of clean energy’s dirtiest problems. Researchers at Columbia Engineering have developed a fast new technique that pulls lithium directly from salty underground brines using a temperature-sensitive solvent, avoiding the giant evaporation ponds that can take years and drain precious water supplies. Even better, the method works on low-qu…

oakridgelabnews posted a photo: Waste heat from the Frontier supercomputer is extracted from circulating water through a closed loop system. Large evaporative cooling towers eject the equivalent of up to 20MW of heat, or 6000 tons, from the primary loop to the atmosphere. This waste heat ejection is the final step in the heat removal process for Frontier and other supercomputers using warm-water …

NASA’s 2025 ISS research reveals breakthroughs in space medicine, materials science, and energy storage, paving the way for lunar and Martian exploration.

American Journal of Engineering and Applied Sciences, Published online: 22 May 2026; doi:10.3844/ajeassp.2026.73.87 Cesium tin chloride (CsSnCl3) has drawn considerable interest as a non-toxic absorber candidate for next-generation photovoltaic devices, offering an attractive combination of affordability, thermal r...

Scientists in Australia have developed a new battery technology that could dramatically reduce the charging time of electric vehicles while still maintaining strong battery performance and lifespan. The advance may help solve one of the biggest concerns many drivers still have about electric cars: long charging times. Researchers from the University of Adelaide created experimental […] The post N…

Nature Communications, Published online: 22 May 2026; doi:10.1038/s41467-026-73484-4 Calcium metal batteries are limited by low reversibility and slow interfacial kinetics. Here, authors design an eccentric solvation structure by introducing monovalent cations and strongly coordinating organoborate anion, which enables fast desolvation and reversible calcium deposition.

Figure: Yearly interprovincial and interregional transmission for ECG, 2022. China’s East China Grid (ECG)—covering Shanghai, Jiangsu, Zhejiang, Anhui, and Fujian—sits at the center of one of the country’s most economically important and electricity-intensive regions. As demand continues to grow, renewable penetration increases, and extreme weather risks become more frequent, policymakers face a …

This paper presents a comprehensive techno-economic and environmental assessment of a grid-connected hybrid renewable energy system (HRES) integrating photovoltaic (PV), wind turbine (WT), and fuel cell (FC) technologies for a case study in Dakhla, Morocco. A detailed modeling framework is developed, including renewable generation, electrolyzer operation, hydrogen storage, and fuel cell conversio…

Aluminum-air (Al-air) batteries are considered promising candidates for electrochemical energy storage due to their theoretical energy density (∼8,100 Wh kg-1), specific capacity (∼3000 mAh·g-1), low cost and the natural abundance of aluminum. However, several hurdles must be overcome before their widespread application. Notably, the aluminum anode is prone to passivation and corrosion, which red…

The next phase of America’s energy future made its Wall Street debut this spring with resounding success. Within just a few weeks, two of the country’s most promising next-generation energy companies made their entrances to the public markets through initial public offerings (IPOs) of their corporate stock. X-energy, a Maryland-based designer of high-temperature gas reactors […]
