Pehea e hana ai ka pākaukau sodium ion?

A pākahiko sodium-ion (pākahi Na-ion)hana like ia me ka pākahi lithium-ion, akā hoʻohana ianā iona sodium (Na⁺)ma kahi onā iona litiuma (Li⁺)e mālama a hoʻokuʻu i ka ikehu.

Eia kahi wehewehe maʻalahi o ke ʻano o kāna hana:

Nā ʻĀpana Kumu:

1. Anode (ʻElekoda Maikaʻi ʻole)- Hana pinepine ʻia me ke kalapona paʻakikī a i ʻole nā ​​​​mea ʻē aʻe e hiki ke hoʻokipa i nā iona sodium.
2. Cathode (ʻElekode Maikaʻi)– Hana ʻia me ka ʻoxide metala i loaʻa ka sodium (e like me ka sodium manganese oxide a i ʻole ka sodium iron phosphate).
3. ʻElektrolita– He mea wai a paʻa paha e hiki ai i nā ion sodium ke neʻe ma waena o ka anode a me ka cathode.
4. Mea hoʻokaʻawale– He membrane e pale ai i ka hoʻopili pololei ʻana ma waena o ka anode a me ka cathode akā e ʻae i nā ions e hele.

Pehea e hana ai:

I ka wā e hoʻouka ai:

1. Neʻe nā iona sodiummai ka cathode a i ka anodema o ka electrolyte.
2. Holo nā electrons ma o ke kaapuni waho (charger) i ka anode.
3. Mālama ʻia nā iona sodium (intercalated) i loko o ka mea anode.

I ka wā e hoʻokuʻu ai:

1. Neʻe nā iona sodiummai ka anode a i ka cathodema o ka electrolyte.
2. Ke kahe nei nā electrons ma o ke kaapuni waho (e hoʻoikaika ana i kahi hāmeʻa) mai ka anode a i ka cathode.
3. Hoʻokuʻu ʻia ka ikehu e hoʻoikaika i kāu hāmeʻa.

Nā Manaʻo Koʻikoʻi:

• Ka mālama ʻana a me ka hoʻokuʻu ʻana i ka ikehuhilinaʻi ma luna o kaka neʻe ʻana o nā iona sodium i mua a i muama waena o nā electrodes ʻelua.
• ʻO ke kaʻina hanahiki ke hoʻohuli ʻia, e ʻae ana i nā pōʻaiapuni hoʻouka/hoʻokuʻu he nui.

Nā Pono o nā Pākahi Sodium-Ion:

• ʻOi aku ka makepononā mea maka (nui ka sodium).
• Palekanama kekahi mau kūlana (ʻoi aku ka pane ʻole ma mua o ka lithium).
• Hana maikaʻi i nā mahana anuanu(no kekahi mau kemika).

Nā mea ʻino:

• ʻO ka nui o ka ikehu haʻahaʻa i hoʻohālikelike ʻia me ka lithium-ion (emi ka ikehu i mālama ʻia no kg).
• I kēia manawaʻaʻole i oʻoʻenehana—emi nā huahana kalepa.
