Filled Sb-Based Skutterudites from 1996–2022

Crystals, 2022
In the present review the focus is set on filled antimony-based skutterudites as they are among the most promising TE materials. Thermoelectric properties (at 300 K and 800 K) of more than 1200 compositions from more than 250 publications from 1996 to ...

A Figure of Merit for Fast-Charging Li-ion Battery Materials.

ACS Nano, 2022
Rate capability is characterized necessarily in almost all battery-related reports, while there is no universal metric for quantitative comparison. Here, we proposed the characteristic time of diffusion, which mainly combines the effects of diffusion ...
