Rising demand for electronic devices and electric vehicles has increased the dependence on secondary ion batteries. While lithium-ion batteries are already popular, a promising alternative sodium-ion batteries (SIB) are struggling to get wider acceptance due to slow ion kinetics affecting their performance. A new polymer-based binder called PMAI addresses this issue by forming a functionalized solid electrolyte interphase. The study demonstrated that SIB with PMAI as an anode binder can have exceptional performance and cyclic stability.

Renewable energy sources like wind and solar are critical to sustaining our planet, but they come with a big challenge: they don't always generate power when it's needed. To make the most of them, we need efficient and affordable ways to store the energy they produce, so we have power even when the wind isn't blowing or the sun isn't shining.

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.

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.

When cars, planes, ships or computers are built from a material that functions as both a battery and a load-bearing structure, the weight and energy consumption are radically reduced. A research group is now presenting an advance in so-called massless energy storage -- a structural battery that could halve the weight of a laptop, make the mobile phone as thin as a credit card or increase the driving range of an electric car by up to 70 percent on a single charge.
