Researchers reveal new mechanisms governing the storage and the movement of sodium ions in hard carbon nanopore anodes.

One alternative electrolysis technology being researched is anion exchange membranes (AEMs), in which the separating membrane allows negatively-charged OH- ions to pass through instead. These are ...

Cations are ions that are positively charged. Anions are ions that are negatively charged. Ions are charged atoms or molecules. If a balanced atom loses one or more electrons, it will become a ...

Dual-ion batteries (DIBs), in which both cations and anions are involved in the electrochemical redox reaction, are one of the most promising candidates to meet the low-cost requirements of commercial ...

Researchers at Columbia Engineering have developed a new gel electrolyte that both improves the lifetime and safety of ...

The most preferred form of energy storage is metal-ion batteries, like lithium-ion batteries. Because of their great energy density and adaptability, they dominate the markets for portable consumer ...

Lithium-ion batteries (LiBs) remain the most widely used rechargeable batteries worldwide, due to their light weight, high energy densities and their short charging times. Energy engineers have been ...
