He aha ka hana ʻana o nā pākahiko sodium ion?

Hana ʻia nā pāpaʻi sodium-ion me nā mea e like me ka hana me nā mea i hoʻohana ʻia i nā pā lithium-ion, akā menā iona sodium (Na⁺).e like me nā mea lawe uku ma kahi o ka lithium (Li⁺). Eia ka haʻihaʻi ʻana o kā lākou mau ʻāpana maʻamau:

1. Cathode (Positive Electrode)

ʻO kēia kahi e mālama ʻia ai nā ion sodium i ka wā o ka hoʻokuʻu ʻana.

Nā mea cathode maʻamau:

• ʻO ka sodium manganese oxide (NaMnO₂)

• ʻO ka hao hao phosphate (NaFePO₄)— like me ka LiFePO₄

• ʻO ka sodium nickel manganese cobalt oxide (NaNMC)

• Prussian Blue a i ʻole Prussian Whitenā mea hoʻohālikelike - nā kumu kūʻai haʻahaʻa, wikiwiki wikiwiki

2. Anode (Negative Electrode)

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

Mea anode maʻamau:

• Kalapona paʻakikī- ka mea anode i hoʻohana nui ʻia

• Pākuʻi kiʻekiʻe kiʻekiʻe (Sn).

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

• ʻO nā oxides ma muli o ka Titanium (e laʻa, NaTi₂(PO₄)₃)

Nānā:ʻO ka graphite, hoʻohana nui ʻia i nā pā lithium-ion, ʻaʻole hana maikaʻi me ka sodium ma muli o kona nui ionic nui.

3. Electrolyte

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

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

• Hoʻohana ʻia kekahi mau hoʻolālā e puka mai neipaʻa-ʻano electrolytes

4. Mea hoʻokaʻawale

He membrane porous e mālama i ka anode a me ka cathode mai ka hoʻopā ʻana akā hiki ke kahe ion.

• Hana mau ʻiapolypropylene (PP) or polyethylene (PE)Papa Hōʻuluʻulu:

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