O ma'a Sodium-ion e faia i mea e tutusa ma mea e fa'aogaina i ma'a lithium-ion, ae fa'atasiniona o le sodium (Na⁺).e pei o le ave taavale ae le o le lithium (Li⁺). O se fa'avasegaga lea o latou vaega masani:
1. Cathode (Electrode Lelei)
O le mea lea e teu ai ion sodium i le taimi e alu ese ai.
Mea masani cathode:
-
Sodium manganese oxide (NaMnO₂)
-
Sodium iron phosphate (NaFePO₄)- tutusa ma le LiFePO₄
-
Sodium nickel manganese cobalt oxide (NaNMC)
-
Prussian Blue po'o Prussian Whiteanalogs - taugofie, mea faʻapipiʻi vave
2. Anode (Electrode Leaga)
O le mea lea e teu ai ion sodium i le taimi o le fa'atumuina.
Mea masani anode:
-
Kaponi malo- o le anode mea sili ona faʻaaogaina
-
Fa'amea fa'avae apa (Sn).
-
Phosphorus poʻo mea faʻavae antimony
-
Omea fa'avae titanium (fa'ata'ita'iga, NaTi₂(PO₄)₃)
Fa'aaliga:Graphite, fa'aaogaina lautele i maa lithium-ion, e le lelei le sodium ona o le tele o le ionic.
3. Electrolyte
Le ala lea e mafai ai ona fealua'i ion sodium i le va o le cathode ma le anode.
-
E masani amasima masima(pei o NaPF₆, NaClO₄) fa'amavae i sesolvent organic(pei o le ethylene carbonate (EC) ma le dimethyl carbonate (DMC))
-
O nisi o mamanu fa'asolosolo fa'aaogaeletise eletise
4. Separatore
O se porous membrane e taofia ai le anode ma le cathode mai le paʻi ae faʻatagaina le tafe o le ion.
-
E masani ona faia ipolypropylene (PP) or polyethylene (PE)Aotelega Laulau:
| Vaega | Mea Fa'ata'ita'iga |
|---|---|
| Cathode | NaMnO₂, NaFePO₄, Prussian Blue |
| Anode | Kaponi Malosi, Apa, Phosphorus |
| Electrolyte | NaPF₆ ile EC/DMC |
| Separatore | Polypropylene poʻo Polyethylene membrane |
Ta'u mai pe e te mana'o i se fa'atusatusaga i le va o ma'a sodium-ion ma ma'a lithium-ion.
