Lightweight Metallic MgB2 Mediates Polysulfide Redox and Promises High-Energy-Density Lithium-Sulfur Batteries

Joule, 2019
Summary The lithium-sulfur battery, despite possessing high theoretical specific energy, faces practical challenges of polysulfide shuttling and low cell-level energy density and hence requires significant functional advances over porous carbon for the ...

Review on high-performance bulk MgB2 superconductors

Journal of Physics D: Applied Physics, 2023
Although the fascinating effect of superconductivity was discovered more than 100 years ago, only a few low-temperature superconductors, especially Nb3Sn and NbTi, have reached everyday-life use.

Ultrathin MgB2 nanosheet-modified polypropylene separator for high-efficiency lithium-sulfur batteries.

Journal of Colloid and Interface Science, 2023
The separator is an important component in lithium-sulfur (Li-S) batteries. However, the conventional polypropylene (PP) separators have the problem of easy shuttling of lithium polysulfide (LiPSs).

MgB2 thin films and MgB2/AlN/MgB2 SIS junctions

Physica C: Superconductivity and its Applications, 2006
Abstract As-grown MgB 2 thin films were fabricated by a sputtering method and a co-evaporation method. We found that the critical temperatures strongly depended on the deposition rate. The MgB 2 thin films showed critical temperatures of 29 K for the sputtering method and 35 K for the co-evaporation method with relatively low substrate temperatures.

Predicting doped MgB2 superconductor critical temperature from lattice parameters using Gaussian process regression

, 2020
Magnesium boride, MgB2, has attracted much attention since the discovery of its superconductivity in 2001. The absence of weak-links in grain boundaries, less prominent anisotropy, rather simple powder-in-tube wire fabrication techniques, and much lower ...

A record-high trapped field of 5.6 T in the stacking of MgB2/TiB2 composite bulks prepared by an in-situ hot isostatic pressing method

Superconductors Science and Technology, 2020
We have studied the trapped field properties of triple and double stacking of MgB2/TiB2 composite superconductor bulks magnetized by field-cooled magnetization. The triple-stacked MgB2/TiB2 bulks trapped a magnetic field of 5.58 T successfully at 11.3 K,
