Zenziwe ngantoni iibhetri ze-sodium ion?

Iibhetri zeSodium-ion zenziwe ngezinto ezifana nezo zisetyenziswa kwiibhetri zeLithium-ion, kodwa zineii-ion zesodium (Na⁺)njengezithwali zetshaja endaweni ye-lithium (Li⁺). Nantsi indlela ezichazwa ngayo izinto zazo eziqhelekileyo:

1. I-Cathode (i-Electrode Elungileyo)

Kulapho kugcinwa khona ii-ion ze-sodium ngexesha lokukhupha.

Izinto eziqhelekileyo ze-cathode:

• I-sodium manganese oxide (NaMnO₂)

• I-phosphate yesinyithi yesodiyam (NaFePO₄)— ifana neLiFePO₄

• I-sodium nickel manganese cobalt oxide (NaNMC)

• I-Prussian Blue okanye i-Prussian Whiteii-analogs — izixhobo ezibiza kancinci, ezitshaja ngokukhawuleza

2. I-Anode (i-Electrode engalunganga)

Kulapho kugcinwa khona ii-ion zesodium ngexesha lokutshaja.

Izinto eziqhelekileyo ze-anode:

• Ikhabhoni eqinileyo— eyona nto isetyenziswa kakhulu kwi-anode

• Iialloy ezisekwe kwiTin (Sn)

• Izinto ezisekwe kwiPhosphorus okanye kwi-antimony

• Ii-oxides ezisekelwe kwi-titanium (umz., NaTi₂(PO₄)₃)

Phawula:I-Graphite, esetyenziswa kakhulu kwiibhetri ze-lithium-ion, ayisebenzi kakuhle ne-sodium ngenxa yobukhulu bayo obukhulu be-ionic.

3. I-Electrolyte

Isixhobo esivumela ii-ion zesodium ukuba zihambe phakathi kwe-cathode kunye ne-anode.

• Ngokwesiqheloityuwa yesodiyam(njengeNaPF₆, NaClO₄) inyibilikiswe kwiisinyibilikisi sendalo(ezifana ne-ethylene carbonate (EC) kunye ne-dimethyl carbonate (DMC))

• Ezinye iindlela zoyilo ezisandula ukuveliswa ziyasetyenziswaii-electrolytes zesimo esiqinileyo

4. Isahluli

I-membrane enemingxuma egcina i-anode kunye ne-cathode zingachukumisi kodwa ivumela ukuhamba kwee-ion.

• Ngokwesiqhelo zenziwe ngei-polypropylene (PP) or i-polyethylene (PE)Itheyibhile yesishwankathelo:

Ndixelele ukuba ufuna uthelekiso phakathi kweebhetri ze-sodium-ion kunye ne-lithium-ion.
