Pehea ka hana ʻana o ka pākaukau sodium ion?

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

Eia kahi wehewehe maʻalahi o ka hana ʻana:

Nā ʻāpana kumu:

1. Anode (Negative Electrode)- Hana pinepine ʻia me ke kalapona paʻakikī a i ʻole nā ​​mea ʻē aʻe e hiki ke hoʻokipa i nā ion sodium.
2. Cathode (Positive Electrode)– Hana maʻamau me ka sodium metala oxide (e laʻa, ka sodium manganese oxide a i ʻole ka sodium iron phosphate).
3. Electrolyte- He 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 ana i ka pili pono ma waena o ka anode a me ka cathode akā hiki ke hele i nā ion.

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 ke kaapuni waho (charger) i ka anode.
3. Mālama ʻia nā ion sodium (intercalated) i loko o ka mea anode.

I ka wā o ka hoʻokuʻu ʻana:

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

Nā mea nui:

• E mālama a hoʻokuʻu i ka ikehuhilinai i kaka neʻe ʻana i hope a me nā iona sodiumma waena o nā electrodes ʻelua.
• ʻO ke kaʻina hanahiki ke hoohuli, e ʻae ana i nā pōʻai he nui / hoʻokuʻu.

ʻO nā mea maikaʻi o nā Bateri Sodium-Ion:

• Maikaʻinā mea maka (he nui ka sodium).
• ʻOi aku ka palekanai kekahi mau kūlana (emi liʻiliʻi ma mua o ka lithium).
• ʻOi aku ka maikaʻi o ka hana ma nā mahana anuanu(no kekahi mau kemika).

Cons:

• ʻOi aku ka liʻiliʻi o ka ikehu i hoʻohālikelike ʻia me ka lithium-ion (emi ka ikehu i mālama ʻia i kēlā me kēia kg).
• I kēia manawaemi ooʻenehana—ʻuʻuku nā huahana kalepa.
