Amabhethri e-sodium ion enziwe ngani?

Amabhethri e-Sodium-ion enziwe ngezinto ezifana nokusebenza kwalezo ezisetshenziswa kumabhethri e-lithium-ion, kodwaama-ion e-sodium (Na⁺)njengezithwali zokushaja esikhundleni se-lithium (Li⁺). Nasi incazelo yezingxenye zazo ezijwayelekile:

1. I-Cathode (I-Electrode Enhle)

Yilapho kugcinwa khona ama-ion e-sodium ngesikhathi sokukhishwa.

Izinto ezivamile ze-cathode:

• I-sodium manganese oxide (NaMnO₂)

• I-phosphate yensimbi ye-sodium (NaFePO₄)— okufana ne-LiFePO₄

• I-sodium nickel manganese cobalt oxide (NaNMC)

• I-Prussian Blue noma i-Prussian Whiteama-analog — izinto ezishibhile, ezishaja ngokushesha

2. I-Anode (i-Electrode Engalungile)

Yilapho kugcinwa khona ama-ion e-sodium ngesikhathi sokushaja.

Izinto ezivamile ze-anode:

• Ikhabhoni eqinile— into esetshenziswa kakhulu ye-anode

• Ama-alloy asekelwe ku-Tin (Sn)

• Izinto ezisekelwe ku-phosphorus noma ku-antimony

• Ama-oxide asekelwe ku-titanium (isb., NaTi₂(PO₄)₃)

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

3. I-Electrolyte

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

• Ngokuvamileusawoti we-sodium(njenge-NaPF₆, i-NaClO₄) encibilikisiwe ku-isinyibilikisi se-organic(njenge-ethylene carbonate (EC) kanye ne-dimethyl carbonate (DMC))

• Amanye amadizayini asanda kuvela asebenzisaama-electrolyte e-solid-state

4. Isihlukanisi

I-membrane enezimbobo evimbela i-anode ne-cathode ukuthintana kodwa ivumela ukugeleza kwe-ion.

• Ngokuvamile kwenziwa ngei-polypropylene (PP) or i-polyethylene (PE)Ithebula Elifingqiwe:

Ngitshele uma ufuna ukuqhathanisa phakathi kwamabhethri e-sodium-ion namabhethri e-lithium-ion.
