Zinc-ion hybrid capacitors with ideal anions in the electrolyte show extra-long performance
18-Nov-2020
Metal-ion hybrid capacitors combine the properties of capacitors and batteries. One electrode uses the capacitive mechanism, the other the battery-type redox processes. Scientists have now scrutinized the role of anions in the electrolyte. The results, which have been published in the journal ...

Researchers led by Profs. LI Xianfeng from the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences recently developed a composite membranefor long-life zinc-based flow batteries. The zinc-based flow battery (ZFB) has capturedmuch attention as a stationary energy ...
Better prediction of degradation rate of magnesium implants
28-Oct-2019
ETH researchers have recently been able to monitor the corrosion of bioresorbable magnesium alloys at the nanoscale over a time scale of a few seconds to many hours. This is an important step towards accurately predicting how fast implants are resorbed by the body to enable the development of ...
