Kedu ihe e ji mee batrị sodium ion?

Emebere batrị sodium-ion site na ihe ndị yiri nke eji na batrị lithium-ion, mana ọ nweresodium (Na⁺) iondị ka ndị na-ebu chaja kama lithium (Li⁺). Lee nkọwa nke ihe ndị ha na-ejikarị eme ihe:

1. Katọde (Elektrode Dị Mma)

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

Ihe ndị a na-ahụkarị na kathode:

• Sodium manganese oxide (NaMnO₂)

• Sodium iron phosphate (NaFe2PO₄)— yiri LiFePO₄

• Sodium nickel manganese cobalt oxide (NaNMC)

• Ọcha Prussian ma ọ bụ Prussiananalogues - ihe dị ọnụ ala, na-ebu ibu ngwa ngwa

2. Anode (Electrode na-adịghị mma)

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

Ihe anode a na-ahụkarị:

• Kabọn siri ike- ihe anode kachasị eji eme ihe

• Ihe ndị e ji tin (Sn) mee

• Ihe ndị e ji phosphorus ma ọ bụ antimony mee

• Oxide ndị e ji titanium mee (dịka ọmụmaatụ, NaTi₂(PO₄)₃)

Rịba ama:Graphite, nke a na-ejikarị eme ihe na batrị lithium-ion, anaghị arụ ọrụ nke ọma na sodium n'ihi nnukwu nha ionic ya.

3. Electrolyte

Ihe na-eme ka sodium ion na-agagharị n'etiti katode na anode.

• N'ozuzu, annu sodium(dịka NaPF₆, NaClO₄) gbazere naihe mgbaze organic(dịka ethylene carbonate (EC) na dimethyl carbonate (DMC))

• Ụfọdụ atụmatụ ndị na-apụta na-ejieletrọlitị siri ike

4. Ihe nkewa

Akpụkpọ ahụ nwere oghere nke na-egbochi anode na kathode imetụ aka mana ọ na-ekwe ka ion na-asọ.

• A na-ejikarị ya eme ihepolypropylene (PP) or polyethylene (PE)Tebụl Nchịkọta:

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