The rapid development of wearable electronics has stimulated the pursuit of advanced stretchable power sources. As a promising candidate, stretchable aqueous zinc‐ion batteries (AZIBs), have attracted unprecedented attention owing to their intrinsic safety, low cost, environmental benignity, and high performance, and can be endowed with additional functionalities to broaden the applications of wearable...
Solid‐State Electrolytes
Compressive stress is caused in Li6.4La3Zr1.4Ta0.6O12 by implanting Ag ions into the near surface region. This compressive stress enables the deflection of mechanically induced cracks, created via nano‐indentation as well as growing dendrites during galvanostatic cycling experiments. This demonstrates ion implantation as a viable technique to design “dendrite‐free” solid‐state...
For supporting active metal, the cavity confinement and mass transfer facilitation lie not in one sack, a trade‐off between high activity and good stability of the catalyst is present.
