Sodium-ion roj teeb yog tsim los ntawm cov ntaub ntawv zoo sib xws hauv kev ua haujlwm rau cov siv hauv lithium-ion roj teeb, tab sis nrogsodium (Na⁺) ionsraws li tus nqi thauj khoom siv lithium (Li⁺). Ntawm no yog ib qho kev faib tawm ntawm lawv cov yam ntxwv:
1. Cathode (zoo electrode)
Qhov no yog qhov chaw sodium ions khaws cia thaum tso tawm.
Cov khoom siv cathode:
-
Sodium manganese oxide (NaMnO₂)
-
Sodium hlau phosphate (NaFePO₄)- zoo ib yam li LiFePO₄
-
Sodium nickel manganese cobalt oxide (NaNMC)
-
Prussian Blue los yog Prussian Dawbanalogues - nqi tsawg, cov khoom siv ceev ceev
2. Anode (tsis zoo electrode)
Qhov no yog qhov chaw sodium ions khaws cia thaum them nyiaj.
Cov khoom siv anode:
-
Cov pa roj carbon- cov khoom siv anode siv dav tshaj plaws
-
Tin (Sn)-raws li alloys
-
Phosphorus los yog antimony-based cov ntaub ntawv
-
Titanium-based oxides (piv txwv li, NaTi₂(PO₄)₃)
Nco tseg:Graphite, dav siv nyob rau hauv lithium-ion roj teeb, tsis ua hauj lwm zoo nrog sodium vim nws loj ionic loj.
3. Electrolyte
Qhov nruab nrab uas tso cai rau sodium ions txav ntawm cathode thiab anode.
-
Feem ntau asodium ntsev(zoo li NaPF₆, NaClO₄) yaj hauv ib qhoorganic kuab tshuaj(xws li ethylene carbonate (EC) thiab dimethyl carbonate (DMC))
-
Qee qhov kev tsim tawm tshiab sivsolid-state electrolytes
4. Separator
Ib daim nyias nyias uas ua kom cov anode thiab cathode tsis txhob kov tab sis tso cai rau ion ntws.
-
Feem ntau ua los ntawmpolypropylene (PP) or polyethylene (PE)Summary Table:
| Cheebtsam | Cov khoom piv txwv |
|---|---|
| Cathode | NaMnO₂, NaFePO₄, Prussian Blue |
| Anode | Hard Carbon, Tin, Phosphorus |
| Electrolyte | NaPF₆ hauv EC/DMC |
| Separator | Polypropylene los yog Polyethylene membrane |
Qhia rau kuv paub yog tias koj xav tau kev sib piv ntawm sodium-ion thiab lithium-ion roj teeb.
