Akhiwe ngani amabhethri e-sodium ion?

Amabhethri e-sodium-ion enziwe ngezinto ezifana nalezo ezisetshenziswa kumabhethri e-lithium-ion, kodwasodium (Na⁺) ionsnjengabathwali bokushaja esikhundleni se-lithium (Li⁺). Nakhu ukuhlukaniswa kwezingxenye zabo ezijwayelekile:

1. I-Cathode (Positive Electrode)

Yilapho i-sodium ion igcinwa khona ngesikhathi sokukhishwa.

Izinto ezijwayelekile ze-cathode:

  • I-Sodium manganese oxide (NaMnO₂)

  • I-sodium iron phosphate (NaFePO₄)- efana ne-LiFePO₄

  • I-sodium nickel manganese cobalt oxide (NaNMC)

  • I-Prussian Blue noma i-Prussian Whiteama-analogues — izinto ezingabizi kakhulu, ezishaja ngokushesha

2. I-Anode (Negative Electrode)

Yilapho ama-ion sodium agcinwa khona ngesikhathi sokushaja.

Izinto ezijwayelekile ze-anode:

  • Ikhabhoni eqinile- i-anode esetshenziswa kakhulu

  • Ama-alloys asekelwe kuthayela (Sn).

  • Izinto ezisekelwe ku-phosphorus noma ze-antimony

  • I-Titanium-based oxides (isb, i-NaTi₂(PO₄)₃)

Qaphela:I-graphite, esetshenziswa kakhulu kumabhethri e-lithium-ion, ayisebenzi kahle nge-sodium ngenxa yobukhulu bayo be-ionic.

3. I-Electrolyte

I-medium evumela ama-ion e-sodium ukuthi ahambe phakathi kwe-cathode ne-anode.

  • Ngokuvamile ausawoti we-sodium(njenge-NaPF₆, NaClO₄) incibilike ku-i-solvent ye-organic(njenge-ethylene carbonate (EC) ne-dimethyl carbonate (DMC))

  • Eminye imiklamo evelayo iyasetshenziswaama-electrolyte aqinile

4. Isihlukanisi

I-membrane enezimbotshana egcina i-anode ne-cathode ukuthi ingathinteki kodwa ivumela ukugeleza kwe-ion.

  • Ivamise ukwenziwai-polypropylene (PP) or i-polyethylene (PE)Ithebula lesifinyezo:

Isakhi Izibonelo Zempahla
I-Cathode NaMnO₂, NaFePO₄, Prussian Blue
I-Anode Ikhabhoni eqinile, ithini, iPhosphorus
I-Electrolyte I-NaPF₆ ku-EC/DMC
Isihlukanisi I-Polypropylene noma i-Polyethylene membrane
 

Ngazise uma ufuna ukuqhathanisa phakathi kwebhethri le-sodium-ion ne-lithium-ion.
