Iibhetri zesodium-ion zenziwe ngezinto ezifana nokusebenza kwezo zisetyenziswa kwiibhetri ze-lithium-ion, kodwasodium (Na⁺) ionsnjengabathwali bentlawulo endaweni ye-lithium (Li⁺). Nalu ulwahlulo lwamacandelo awo aqhelekileyo:
1. I-Cathode (i-Electrode ePositive)
Yilapho i-sodium ion igcinwa khona ngexesha lokukhutshwa.
Izixhobo eziqhelekileyo ze-cathode:
-
Isodium manganese oxide (NaMnO₂)
-
I-sodium iron phosphate (NaFePO₄)- iyafana neLiFePO₄
-
Nickel yesodium manganese cobalt oxide (NaNMC)
-
I-Prussian Blue okanye iPrussian Whiteama-analogues - amaxabiso aphantsi, izinto zokutshaja ngokukhawuleza
2. I-Anode (I-Electrode eNegative)
Yilapho i-ion zesodium zigcinwa khona ngexesha lokutshaja.
Izixhobo eziqhelekileyo ze-anode:
-
Ikhabhoni enzima- eyona nto isetyenziswa kakhulu kwi-anode
-
I-Tin (Sn)-based alloys
-
Iphosphorus okanye izinto ezisekelwe kwi-antimony
-
I-Titanium-based oxides (umz., NaTi₂(PO₄)₃)
Phawula:I-graphite, esetyenziswa ngokubanzi kwiibhetri ze-lithium-ion, ayisebenzi kakuhle kunye nesodium ngenxa yobukhulu bayo be-ionic.
3. Electrolyte
I-medium evumela i-ion yesodium ukuba ihambe phakathi kwe-cathode kunye ne-anode.
-
Ngokuqhelekileyo aityuwa yesodium(njenge-NaPF₆, NaClO₄) inyibilikiswe kwi-i-solvent ephilayo(ezifana ne-ethylene carbonate (EC) kunye ne-dimethyl carbonate (DMC))
-
Uyilo olusakhulayo lusebenzisai-electrolytes eqinile
4. Umahluli
I-membrane ene-porous egcina i-anode kunye ne-cathode ukuba ingachukumisi kodwa ivumela ukuhamba kwe-ion.
-
Ngokuqhelekileyo yenziwei-polypropylene (PP) or i-polyethylene (PE)Itheyibhile yesiShwankathelo:
| Icandelo | Imizekelo yezinto eziphathekayo |
|---|---|
| Cathode | NaMnO₂, NaFePO₄, Prussian Blue |
| Anode | Ikhabhoni enzima, iTin, iPhosphorus |
| Electrolyte | I-NaPF₆ kwi-EC/DMC |
| Umahluli | Polypropylene okanye Polyethylene inwebu |
Ndazise ukuba ufuna uthelekiso phakathi kwe-sodium-ion kunye neebhetri ze-lithium-ion.
