Dendrites are a problem in lithium-based rechargeable batteries. Over the many charge/discharge cycles, these tiny crystal growths form naturally on the lithium surface and create a kind of branching ...

Scientists have uncovered a root cause of the growth of needle-like structures -- known as dendrites and whiskers -- that plague lithium batteries, sometimes causing a short circuit, failure, or even ...

Battery dendrites are not caused by electrical origins, but instead have mechanical sources. The dendrites propagate due to fracture of the electrolyte and subsequent crack filling-in. Stresses on the ...

Metal batteries, with active metals as anodes, are considered as one of the most promising solutions to achieve the energy upgrade of battery technologies, yet their practical applications are ...

Lithium-ion batteries have revolutionized the way we power our gadgets, and they even nabbed the Nobel Prize in Chemistry this year. But scientists want to make even more powerful versions. Replacing ...

The novel nanoscale network structure of these solid polymer electrolytes dramatically improved network mechanical properties, which was demonstrated to be critical to lithium dendrite resistance. The ...
