Sodium Nickel Manganese Oxide Hmoov

 

Sodium Nickel Manganese Oxide (NaNi_0.5Mn_1.5O₄) Hmoov rau Sodium Ion Roj Teeb Cathode

 

Sodium-ion batteries (SIBs) tau lees paub tias yog ib qho ntawm cov cuab yeej siv tau zoo tshaj plaws rau cov roj teeb uas muaj nqi qis dua vim muaj cov peev txheej ntau ntawm sodium los ntawm dej hiav txwv lossis hlau xuab zeb. SIBs muaj cov txheej txheem ntawm tes zoo sib xws thiab kev ua haujlwm rau lub zog cia nrog lithium-ion roj teeb (LIBs). Txawm li cas los xij, sodium ion (Na^ntxiv) intercalation thiab khaws cia, vim qhov loj dua ionic vojvoog ntawm 1.02 Å thiab hnyav dua ntawm 22.99 g·mol⁻¹piv nrog Li^ntxiv(0.76 Å & 6.94 g·mol⁻¹), yog qhov nyuaj dua li Li-ion roj teeb.

Sodium nickel manganese oxide (NaNi_0.5Mn_1.5O₄) yog cov khoom muaj peev xwm SIB cathode. NaNi_0.5Mn_1.5O₄muaj cov qauv spinel rau sodium ntxig / rho tawm txheej txheem nrog Mn^{4 plus ib}/Mn^{3 plus ib}thiab Ni^{4 plus ib}/Ni^{3 plus ib}redox ob peb.
