P2-type Na2/3Ni1/3Mn2/3O2 (PNNMO) has been extensively studied because of its desirable electrochemical properties as a positive electrode for sodium-ion batteries. PNNMO exhibits intralayer transition-metal ordering Ni and Mn Na+/vacancy ordering. The is often considered major impediment to fast Na+ transport can be affected by We show neutron/X-ray diffraction density functional theory (DFT) calculations that Li doping (Na2/3Li0.05Ni1/3Mn2/3O2, LFN5) promotes ABC-type interplanar Ni/Mn...
The structure-property relationships of metal-organic framework (MOF) based solid-state electrolytes are not well understood. Herein, a systematic investigation twelve Zr(IV)-based UiO-66 MOFs with varying ether-chain functional groups was carried out to elucidate the critical microscopic interactions that facilitate improved electrolyte performance. Enhanced sampling molecular dynamics (MD) simulations were employed and revealed three-tier ion hopping mechanism: linker-linker hopping,...
