He aha nā mea i hana ʻia ai nā pila sodium ion?

Hana ʻia nā pila sodium-ion me nā mea like ka hana me nā mea i hoʻohana ʻia i nā pila lithium-ion, akā menā iona sodium (Na⁺)ma ke ʻano he mau mea lawe ukana ma kahi o ka lithium (Li⁺). Eia kahi wehewehe ʻana o kā lākou mau ʻāpana maʻamau:

1. Cathode (ʻElekode Maikaʻi)

ʻO kēia kahi e mālama ʻia ai nā iona sodium i ka wā e hoʻokuʻu ʻia ai.

Nā mea cathode maʻamau:

• ʻO ka sodium manganese oxide (NaMnO₂)

• Sodium hao phosphate (NaFePO₄)— like me LiFePO₄

• ʻO ka sodium nickel manganese cobalt oxide (NaNMC)

• Polū Prussian a i ʻole keʻokeʻo Prussiannā analogs - nā mea hana haʻahaʻa ke kumukūʻai, hoʻouka wikiwiki

2. Anode (ʻElekoda Maikaʻi ʻole)

ʻO kēia kahi e mālama ʻia ai nā iona sodium i ka wā e hoʻouka ai.

Nā mea anode maʻamau:

• Kalapona paʻakikī— ka mea anode i hoʻohana nui ʻia

• Nā mea hoʻohuihui i hoʻokumu ʻia me ka tin (Sn)

• Nā mea Phosphorus a i ʻole nā ​​​​mea i hoʻokumu ʻia i ka antimony

• Nā ʻokikene i hoʻokumu ʻia i ka titanium (e laʻa, NaTi₂(PO₄)₃)

Hoʻomaopopo:ʻO ka Graphite, i hoʻohana nui ʻia i nā pila lithium-ion, ʻaʻole hana maikaʻi me ka sodium ma muli o kona nui ionic nui.

3. ʻElektrolita

ʻO ke ʻano hana e hiki ai i nā ion sodium ke neʻe ma waena o ka cathode a me ka anode.

• ʻO ka maʻamau hepaʻakai sodium(e like me NaPF₆, NaClO₄) i hoʻoheheʻe ʻia i loko o kahimea hoʻoheheʻe organik(e like me ka ethylene carbonate (EC) a me ka dimethyl carbonate (DMC))

• Hoʻohana kekahi mau hoʻolālā hounā electrolytes paʻa-kūlana

4. Mea hoʻokaʻawale

He membrane porous e pale ai i ka hoʻopā ʻana o ka anode a me ka cathode akā e ʻae i ke kahe ʻana o ka ion.

• Hana pinepine ʻia mepolypropylene (PP) or polyethylene (PE)Papa Hōʻuluʻulu Manaʻo:

E haʻi mai iaʻu inā makemake ʻoe i ka hoʻohālikelike ʻana ma waena o nā pila sodium-ion a me nā pila lithium-ion.
