Covalent Carbide Interconnects Enable Robust Interfaces and Thin SEI for Graphite Anode Stability under Extreme Fast Charging.

Carbonaceous and carbon-coated electrodes are ubiquitous in electrochemical energy storage and conversion technologies due to their electrochemical stability, lightweight nature, and relatively low cost. However, traditional reliance on conductive additives and binders leads to impermanent electrical pathways. Here, a general approach is presented to fabricate robust electrodes with a progressive failure mechanism by introducing carbide-based interconnects grown via carbothermal conversion of (5 wt%) titanium hydride nanoparticles.

Thermoelectric and Mechanical Properties of Environmentally Friendly MgSiSnBi/SiC Composites.

In this work, polycrystalline n-type MgSiSnBi dispersed with wt % β-SiC nanoparticles ( = 0, 0.5, 1.0, 1.

BaCuSiTe: A Noncentrosymmetric Semiconductor with CuTe Tetrahedra and Ethane-like SiTe Units.

BaCuSiTe was prepared from the elements in a solid-state reaction at 973 K, followed by slow cooling to room temperature. This telluride adopts a new, hitherto unknown structure type, crystallizing in the noncentrosymmetric space group with = 7.5824(1) Å, = 8.

Effect of mixed occupancies on the thermoelectric properties of BaCuSeTe polychalcogenides.

The title materials have been reported earlier to be p-type thermoelectrics when x = 0.1 and y = 0. Here, we studied the properties after varying the Cu and the Se/Te concentrations.
