Conceived by scientists in China, the battery was built with a special hydrogel electrolyte made of polyacrylamide (PAM), zinc sulfate (ZnSO4), glycerol (GL), and acetonitrile (AN). The device showed ...

For many years, cesium atomic clocks have been reliably keeping time around the world. But the future belongs to even more accurate clocks: optical atomic clocks. In a few years' time, they could ...

Researchers in Japan have adopted a new calcium-doping strategy to improve the stability and electrochemical properties of NFM, a cathode material used in sodium-ion batteries. The new technique ...

As the global demand for sustainable and cost-effective energy solutions continues to rise, the development of advanced energy storage materials becomes increasingly important. Solid-state sodium-ion ...

(Nanowerk Spotlight) Lithium-ion batteries, with their high energy density and long lifetimes, have dominated the rechargeable battery market for decades. However, lithium's scarcity and rising cost ...

Sodium-ion batteries are being investigated as a viable cost-effective, more environmentally friendly, and easier-to-source alternative to lithium-ion. 60% capacity is retained after 300 cycles.
