Tuning Pore Size in Graphene in the Angstrom Regime for Highly Selective Ion-Ion Separation

Kumar Varoon Agrawal, Kuang-Jung Hsu, Kangning Zhao, Luis Francisco Villalobos Vazquez de la Parra, Shaoxian Li, Heng-Yu Chi, Wan-Chi Lee, Yuyang Zhang

Zero-dimensional pores spanning only a few angstroms in size in two-dimensional materials such as graphene are some of the most promising systems for designing ion-ion selective membranes. However, the key challenge in the field is that so far a crack-free ...

A pre-fatigue training strategy to stabilize LiCoO2 at high voltage

Lei Zhang, Kangning Zhao, Rui Xia

Layered cathodes are among the most promising cathodes for high-energy-density Li-ion batteries, yet hindered by the structural degradation from both bulk strain and surface oxygen loss at high voltage (above 4.5 V). Herein, we report a pre-fatigue trainin ...
