Polyrotaxane‐Assembled Semi‐Interpenetrating Polymer Electrolytes Enabling High‐Voltage Lithium Metal Batteries

Advanced Science, EarlyView.
This work develops a polyrotaxane‐based supramolecular semi‐interpenetrating network electrolyte. Its unique architecture decouples ion transport, achieving high ionic conductivity (0.18 mS cm−1), a superior Li+ transference number (> 0.73), and an extended electrochemical window (> 4.9 V), thereby significantly enhancing the performance of high ...

Alloying Cu, Fe, and Co in Ni/YSZ Electrodes for High‐Temperature CO2 Electrolysis: Impact on TPB Density, Activity, and Carbon Deposition Resistance

Carbon Energy, EarlyView.
Systematic alloying of Ni with Cu, Fe, and Co in Ni/YSZ electrodes modifies active site density up to 43%, decreases activation energies by up to 44%, and reduces carbon deposition fourfold. Cu–Ni alloy is among the most promising alloy catalysts for electrochemical CO2 reduction in SOECs.

Oxygen transfer properties of ion-implanted yttria-stabilized zirconia [PDF]

Solid State Ionics, 1992
The influence of surface modification by ion implantation on oxygen transfer in yttria-stabilized zirconia (YSZ) has been studied. Implantation of 15 keV 56Fe in YSZ with a maximum dose of 8×1016 atoms cm−2 yields reproducible surface layers of approximately 20 nm deep with a maximum Fe cation fraction of 0.5 at the surface.

Design of High‐Performance MnCo1.5Cu0.5O4 Spinel Contact Material with Optimized Electrical Conductivity and Thermal Stability for Solid Oxide Electrolysis Cells by Cu Doping

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Cu‐doped spinel MnCo1.5Cu0.5O4 exhibits excellent conductivity and stability as SOC contact material. After 1000‐h aging at 850 °C, the contact layer maintains a 10 mΩ cm2 ASR value, and a single‐cell stack achieves a H2O/CO2 co‐electrolysis power density of 0.52 W cm−2.
