Effect of fluorination and Li-excess on the Li migration barrier in Mn-based cathode materials
Zinab Jadidi,Zinab Jadidi,Tina Chen,Tina Chen,Penghao Xiao,Alexander Urban,Gerbrand Ceder,Gerbrand Ceder +7 more
TL;DR: In this paper, the authors investigated the effects of both F substitution and the accompanying Li-excess on Li migration barriers using first-principles calculations and showed that F substitution has a small negative effect on Li mobility while Li-Excess decreases Li migration barrier.

Tan Shi,Tan Shi,Penghao Xiao,Deok-Hwang Kwon,Gopalakrishnan Sai Gautam,Khetpakorn Chakarawet,Hyunchul Kim,Shou-Hang Bo,Shou-Hang Bo,Gerbrand Ceder,Gerbrand Ceder +10 more
TL;DR: In this article, the synthesis of cation-disordered rocksalt NaMO2 (M = 3D transition metal) via a martensitic-like phase transformation from β-NaFeO2 was reported.
Journal ArticleDOI
Coupling of Graphene Quantum Dots with MnO2 Nanosheets for Boosting Capacitive Storage in Ionic Liquid Electrolyte
TL;DR: In this paper , a new design of graphene quantum dots (GQDs) integrated with MnO 2 nanosheets is proposed to construct a GQDs@MnO 2 composite electrode for IL-based supercapacitor.
Journal ArticleDOI
Superior Oxygen Electrocatalysis on RuSex Nanoparticles for Rechargeable Air Cathodes
Ji-Hoon Jang,Eunjik Lee,Penghao Xiao,Kyusung Park,In Young Kim,Graeme Henkelman,Seong Ju Hwang,Young-Uk Kwon,John B. Goodenough +8 more
TL;DR: In this paper, a supercritical-ethanol-fluid synthesis of Se-modified Ru nanoparticles nucleated on carbon defects is reported, and it is demonstrated that these nanoparticles provide, with >70% efficiency at 1 A g−1, a highly active and reversible oxygen-reduction/oxygen-evolution reaction on an air cathode in a nonaqueous electrolyte.
