Shunsuke Yagi,Ikuya Yamada,Hirofumi Tsukasaki,Akihiro Seno,Makoto Murakami,Hiroshi Fujii,Hungru Chen,Naoto Umezawa,Hideki Abe,Norimasa Nishiyama,Shigeo Mori +10 more
TL;DR: It is reported that the Fe4+-based quadruple perovskite CaCu3Fe4O12 has high activity, which is comparable to or exceeding those of state-of-the-art catalysts such as Ba 0.5Sr0.5Co0.8Fe0.2O3−δ and the gold standard RuO2.
Journal ArticleDOI
Lithium Extraction Mechanism in Li-Rich Li2MnO3 Involving Oxygen Hole Formation and Dimerization
Hungru Chen,M. Saiful Islam +1 more
TL;DR: In this paper, Li extraction is charge-compensated by oxidation of the oxide anion, so that the overall delithiation reaction involves lattice oxygen loss and localized holes on oxygen (O) are formed as the first step but are not stable leading to oxygen dimerization and eventually to the formation of molecular O2.
Journal ArticleDOI
The influence of large cations on the electrochemical properties of tunnel-structured metal oxides
Yifei Yuan,Yifei Yuan,Chun Zhan,Kun He,Hungru Chen,Wentao Yao,Soroosh Sharifi-Asl,Boao Song,Zhenzhen Yang,Anmin Nie,Anmin Nie,Xiangyi Luo,Hui Wang,Stephen M. Wood,Khalil Amine,M. Saiful Islam,Jun Lu,Reza Shahbazian-Yassar,Reza Shahbazian-Yassar +18 more
TL;DR: The role of tunnel cations in governing the electrochemical properties of electrode materials is reported by focusing on potassium ions in α-MnO2, and the presence of cations inside 2 × 2 tunnels of manganese dioxide increases the electronic conductivity, and improves lithium ion diffusivity.
Journal ArticleDOI
High voltage structural evolution and enhanced Na-ion diffusion in P2-Na2/3Ni1/3-xMgxMn2/3O2 (0 < x < 0.2) cathodes from diffraction, electrochemical and ab initio studies
Nuria Tapia-Ruiz,Wesley M. Dose,Neeraj Sharma,Hungru Chen,Jennifer Heath,James W. Somerville,Urmimala Maitra,M. Saiful Islam,Peter G. Bruce +8 more
TL;DR: In this paper, the effects of Mg substitution on the structure, electrochemical performance and Na-ion diffusion in high voltage P2-type Na2/3Ni1/3−xMgxMn 2/3O2 (0 < x < 0.2) cathode materials for Naion batteries were investigated.
Journal ArticleDOI
Effects of cationic substitution on structural defects in layered cathode materials LiNiO2
TL;DR: In this article, the effect of Co, Mn and Al substitution on defect formation in LiNiO2-based compounds was investigated. And the presence of Ni2+ in the Li layer can be rationalized using ideas of superexchange interactions, which explains the better thermal stability obtained by early transition metal or Al substitution.
