A New, Inexpensive Catalyst Speeds The Production Of Oxygen From Water by David L. Chandler

An electrochemical reaction that splits apart water molecules to produce oxygen is at the heart of multiple approaches aiming to produce alternative fuels for transportation. But this reaction has to be facilitated by a catalyst material, and today’s versions require the use of rare and expensive elements such as iridium, limiting the potential of such […]

This Compressed Air Grid ‘Battery’ Is An Energy Storage Game Changer by Caroline Delbert

Pumped hydropower is great. This method might be even better. Two new compressed air storage plants will soon rival the world’s largest non-hydroelectric facilities and hold up to 10 gigawatt hours of energy. But what is advanced compressed air energy storage (A-CAES), exactly, and why is the method about to have a moment? Compressed air […]

A High-Energy Density And Long-Life Initial-Anode-Free Lithium Battery by Ingrid Fadelli

Lithium-metal batteries (LMBs), an emerging type of rechargeable lithium-based batteries made of solid-state metal instead of lithium-ions, are among the most promising high-energy-density rechargeable battery technologies. Although they have some advantageous characteristics, these batteries have several limitations, including a poor energy density and safety-related issues. In recent years, researchers have tried to overcome these limitations […]

Reviewing Recent Advancements In The Development Of Solid-State Batteries by Ingrid Fadelli

Solid state batteries (SSBs) are an emerging battery technology with high energy densities that could compete with lithium-ion batteries (LIBs), which power a wide range of electronic devices on the market today. In contrast with classic LIBs, SSBs have a solid ‘ceramic’-based electrolyte that separates the anode and cathode inside the battery. In some batteries, […]
