Mabhatiri e sodium ion anogadzirwa nei?

Mabhatiri eSodium-ion anogadzirwa nezvinhu zvakafanana neanoshandiswa mumabhatiri eLithium-ion, asi anemaayoni e sodium (Na⁺)sezvinhu zvinotakura chaji pachinzvimbo che lithium (Li⁺). Heino kupatsanurwa kwezvikamu zvavo zvakajairika:

1. Cathode (Electrode Yakanaka)

Apa ndipo panochengetwa ma sodium ions panguva yekubuda kweropa.

Zvinhu zvakajairika zve cathode:

• Sodium manganese oxide (NaMnO₂)

• Sodium iron phosphate (NaFePO₄)— zvakafanana neLiFePO₄

• Sodium nickel manganese cobalt oxide (NaNMC)

• Bhuruu rePrussia kana kuti Chena rePrussiaanalogi — zvinhu zvinodhura zvishoma, zvinochaja nekukurumidza

2. Anode (Electrode Isina Kunaka)

Apa ndipo panochengetwa ma sodium ions panguva yekuchaja.

Zvinhu zvakajairika zveanode:

• Kabhoni yakaoma— chinhu chinoshandiswa zvakanyanya cheanode

• Zvishongo zvakagadzirwa neTin (Sn)

• Zvinhu zvakagadzirwa nephosphorus kana antimony

• Ma oxides akavakirwa pa titanium (semuenzaniso, NaTi₂(PO₄)₃)

Cherechedza:Graphite, inoshandiswa zvakanyanya mumabhatiri e lithium-ion, haishande zvakanaka ne sodium nekuda kwehukuru hwayo hwe ionic.

3. Electrolyte

Iyi nzira inobvumira maion e sodium kufamba pakati pe cathode ne anode.

• Kazhinji amunyu wesodium(seNaPF₆, NaClO₄) yakanyungudutswa muorganic solvent(senge ethylene carbonate (EC) uye dimethyl carbonate (DMC))

• Mamwe magadzirirwo matsva anoshandisamaelectrolyte emamiriro akasimba

4. Musiyanisi

Kamudzira kane maburi kanodzivirira anode ne cathode kuti zvisabatane asi kachibvumira maion kuyerera.

• Kazhinji zvakagadzirwa nepolypropylene (PP) or polyethylene (PE)Tafura Yepfupiso:

Ndiudzei kana muchida kuenzanisa mabhatiri e sodium-ion ne lithium-ion.
