Sodium-ion mabhatiri anogadzirwa nezvinhu zvakafanana mukushanda kune anoshandiswa mumabhatiri e lithium-ion, asi ainesodium (Na⁺) ionssevanotakura vatakuri panzvimbo yelithium (Li⁺). Heino kupatsanurwa kwezvakajairwa zvikamu zvavo:
1. Cathode (Positive Electrode)
Apa ndipo panochengetwa sodium ions panguva yekubuda.
Common cathode zvinhu:
-
Sodium manganese oxide (NaMnO₂)
-
Sodium iron phosphate (NaFePO₄)- zvakafanana neLiFePO₄
-
Sodium nickel manganese cobalt oxide (NaNMC)
-
Prussian Blue kana Prussian Whiteanalogs - yakaderera-inodhura, inokurumidza-kuchaja zvinhu
2. Anode (Negative Electrode)
Apa ndipo panochengetwa sodium ions panguva yekuchaja.
Common anode zvinhu:
-
Hard carbon- iyo inonyanya kushandiswa anode zvinhu
-
Tin (Sn)-based alloys
-
Phosphorus kana antimony-based materials
-
Titanium-based oxides (semuenzaniso, NaTi₂(PO₄)₃)
Cherechedza:Graphite, inoshandiswa zvakanyanya mumabhatiri e-lithium-ion, haishande zvakanaka ne sodium nekuda kwehukuru hwayo ionic.
3. Electrolyte
Iyo yepakati inobvumira sodium ions kufamba pakati pe cathode uye anode.
-
Kazhinji asodium munyu(seNaPF₆, NaClO₄) yakanyungudutswa muneorganic solvent(zvakadai se ethylene carbonate (EC) uye dimethyl carbonate (DMC))
-
Mamwe madhizaini ari kubuda anoshandisayakasimba-state electrolytes
4. Separator
Iyo porous membrane inochengetedza anode uye cathode kubva pakubata asi inobvumira ion kuyerera.
-
Kazhinji yakagadzirwapolypropylene (PP) or polyethylene (PE)Summary Table:
| Chikamu | Mienzaniso Yezvinhu |
|---|---|
| Cathode | NaMnO₂, NaFePO₄, Prussian Blue |
| Anode | Yakaoma Carbon, Tin, Phosphorus |
| Electrolyte | NaPF₆ muEC/DMC |
| Separator | Polypropylene kana Polyethylene membrane |
Ndizivise kana iwe uchida kuenzanisa pakati pe sodium-ion uye lithium-ion mabhatiri.
