- Abstract:
- ... Li-Se battery is a promising energy storage candidate owing to its high theoretical volumetric capacity and safe operating condition. In this work, for the first time, we report using the whole organic Melamine-based porous polymer networks (MPNs) as a precursor to synthesize a N, O, S co-doped hierarchically porous carbon nanobelts (HPCNBs) for both Li-ion and Li-Se battery. The N, O, S co-doping ...

P-type elemental Te has exhibited a high thermoelectric (TE) figure of merit zT of ∼1.0 around 600 K, but its performance near room temperature is much deteriorated due to grain boundary scattering. In this work, the average zT of Te₀.₉₈As₀.₀₂ alloys is remarkably enhanced via increasing the grain size. Through increasing the grain size, the room temperature power factor is boosted from 0.44 × 10⁻ ...
