Charging ahead towards future low-cost polymer zinc-ion batteries

With global demand for lithium-ion batteries fast depleting reserves of raw materials, experts are seeking safe, affordable and reliable alternatives for rechargeable batteries. Aqueous zinc-ion batteries (AZIBs) could be the answer to producing low-cost alternatives from abundant feedstocks, and scientists are paving the way for the production of simple and practical polymer AZIBs using organic cathodes for more sustainable energy storage technology.

New proteins involved in regulating the cell membrane

Scientists have uncovered new details about how cells manage the distribution of lipids in their cell membrane. These lipids, known as phospholipids, are arranged in a bilayer of membranes, regulating entry and exit of certain molecules to maintain a stable internal environment.

Folded or cut, this lithium-sulfur battery keeps going

Most rechargeable batteries that power portable devices, such as toys, handheld vacuums and e-bikes, use lithium-ion technology. But these batteries can have short lifetimes and may catch fire when damaged. To address stability and safety issues, researchers have designed a lithium-sulfur (Li-S) battery that features an improved iron sulfide cathode. One prototype remains highly stable over 300 charge-discharge cycles, and another provides power even after being folded or cut.
