Kedu ihe eji eme batrị sodium ion?

A na-eme batrị sodium-ion nke ihe ndị yiri nke a na-eji na batrị lithium-ion, mana ya.sodium (na) iondị ka ndị na-ebu ụgwọ kama lithium (Li⁺). Nke a bụ nbibi nke ihe ndị a na-ahụkarị:

1. Cathode (Electrode dị mma)

Nke a bụ ebe a na-echekwa ion sodium n'oge mwepu.

Ngwa cathode nkịtị:

• Sodium manganese oxide (NaMnO₂)

• Sodium iron phosphate (NaFePO₄)- yiri LiFePO₄

• Sodium nickel manganese cobalt oxide (NaNMC)

• Prussian Blue ma ọ bụ Prussian Whiteanalogs - ọnụ ala, ihe na-ebu ngwa ngwa

2. Anode (Negative Electrode)

Nke a bụ ebe a na-echekwa ion sodium n'oge ịchaji.

Ngwa anode nkịtị:

• Carbon siri ike- ihe kachasị eji anode eme ihe

• Alloys dabere na Tin (Sn).

• Phosphorus ma ọ bụ ihe ndị sitere na antimony

• oxides dabere Titanium (dịka, NaTi₂(PO₄)₃)

Mara:Graphite, nke a na-ejikarị na batrị lithium-ion, anaghị arụ ọrụ nke ọma na sodium n'ihi nnukwu ionic size.

3. Electrolyt

Usoro nke na-enye ion sodium ohere ịkwaga n'etiti cathode na anode.

• Na-emekarị annu sodium(dị ka NaPF₆, NaClO₄) gbazere n'ime iheihe mgbaze organic(dị ka ethylene carbonate (EC) na dimethyl carbonate (DMC))

• Ụfọdụ atụmatụ na-apụta na-ejisiri ike-ala electrolytes

4. Nkewa

Akpụkpọ anụ nwere oghere nke na-eme ka anode na cathode ghara imetụ aka mana na-enye ohere ka ion na-asọba.

• A na-emekarị nkepolypropylene (PP) or Polyethylene (PE)Okpokoro nchịkọta

Mee ka m mata ma ọ bụrụ na ịchọrọ ntụnyere n'etiti batrị sodium-ion na lithium-ion batrị.
