He loiloi kumukūʻai a me nā kumuwaiwai o nā pila sodium-ion?

1. Nā kumukūʻai o nā mea maka

Sodium (Na)

• Ka nuiʻO ka sodium ka mea nui ʻeono ma ka ʻili o ka Honua a loaʻa koke ia i loko o nā waihona wai kai a me ka paʻakai.
• KumukūʻaiHaʻahaʻa loa i ka hoʻohālikelike ʻia me ka lithium — ʻo ka sodium carbonate ka mea maʻamau$40–$60 no ke tona, ʻoiai ʻo ka lithium carbonate$13,000–$20,000 no ke tona(e like me ka ʻikepili mākeke hou).
• HopenaʻO ka pōmaikaʻi nui o ke kumukūʻai i ka loaʻa ʻana o nā mea maka.

Nā Mea Cathode

• ʻO ka maʻamau, hoʻohana nā pila sodium-ion i kēia mau mea:
  • Nā analog polū Prussian (PBAs)
  • Sodium hao phosphate (NaFePO₄)
  • ʻO nā ʻokikene i hoʻopaʻa ʻia (e laʻa, Na₀.₆₇[Mn₀.₅Ni₀.₃Fe₀.₂]O₂)
• ʻO kēia mau meaʻoi aku ka maʻalahi ma mua o ka lithium cobalt oxide a i ʻole ka nickel manganese cobalt (NMC)Hoʻohana ʻia i loko o nā pila Li-ion.

Nā Mea Anode

• Kalapona paʻakikīʻo ia ka mea anode maʻamau.
• KumukūʻaiʻOi aku ka makepono ma mua o ka graphite a i ʻole silicon i hoʻohana ʻia i loko o nā pila Li-ion, no ka mea hiki ke loaʻa mai ka biomass (e laʻa me nā pūpū niu, ka lāʻau).

2. Nā kumukūʻai hana

Nā Lako a me nā ʻOihana

• HoʻohālikelikeʻO ka hana ʻana o ka pila sodium-ionkūlike ka hapa nui me nā laina hana pākahi lithium-ion e kū nei, e hoʻēmi ana i ka CAPEX (Capital Expenditure) no nā mea hana e hoʻololi ana a hoʻonui paha.
• Nā kumukūʻai electrolyte a me ka mea hoʻokaʻawaleUa like me Li-ion, ʻoiai ke holomua nei ka hoʻonui ʻana no ka Na-ion.

Ka Hopena o ka Ikehu

• Loaʻa i nā pila sodium-ionhaʻahaʻa ka nui o ka ikehu(~100–160 Wh/kg vs. 180–250 Wh/kg no Li-ion), kahi e hoʻonui ai i ke kumukūʻaino kēlā me kēia anakahi o ka ikehu i mālama ʻia.
• Eia naʻe,ola pōʻaiapunia mepalekanahiki i nā ʻano hana ke uku i nā kumukūʻai hana lōʻihi.

3. Loaʻa nā kumuwaiwai a me ke kūpaʻa

Sodium

• Kūlike ʻole o ka GeopoliticalHoʻolaha ʻia ka sodium ma ka honua holoʻokoʻa a ʻaʻole i hoʻonui ʻia ma nā wahi i pilikia i ka hakakā a i ʻole nā ​​​​wahi i hoʻokahi wale ʻia e like me ka lithium, cobalt, a i ʻole nickel.
• Ka hoʻomau ʻanaKiʻekiʻe - loaʻa ka unuhi ʻana a me ka hoʻomaʻemaʻe ʻanaka hopena liʻiliʻi o ke kaiapunima mua o ka hana ʻeli ʻana o ka lithium (ʻoi aku hoʻi mai nā kumu pōhaku paʻakikī).

Litiuma

• Ka pilikia o nā kumuwaiwaiNā helehelena Lithiumka loli ʻana o ke kumukūʻai, nā kaulahao lako i kaupalena ʻia, a menā kumukūʻai kaiapuni kiʻekiʻe(ka unuhi ʻana i ka wai mai nā brine, nā hoʻokuʻu ʻana o CO₂).

4. Ka Scalability a me ka hopena o ke kaulahao lako

• ʻO ka ʻenehana sodium-ionhiki ke hoʻonui nui ʻiama muli oka loaʻa ʻana o nā mea maka, kumukūʻai haʻahaʻa, a meua hoʻemi ʻia nā palena o ke kaulahao lako.
• Hoʻokama nui ʻiahiki ke hōʻoluʻolu i ke kaomi ma nā kaulahao hoʻolako lithium, ʻoi aku hoʻi noka mālama ikehu paʻa, nā kaʻa huila ʻelua, a me nā EV haʻahaʻa.

Hopena

• Nā pila sodium-ionhāʻawi i kahikūpono ke kumukūʻai, hoʻomauhe koho ʻē aʻe i nā pila lithium-ion, kūpono loa nowaihona pūnaewele, nā EV haʻahaʻa ke kumukūʻai, a menā mākeke e ulu ana.
• I ka wā e ulu ai ka ʻenehana,ka pono o ka hana ʻanaa menā hoʻomaikaʻi ʻana o ka nui o ka ikehumanaʻo ʻia e hoʻemi hou aku i nā kumukūʻai a hoʻonui i nā noi.

Makemake ʻoe e ʻike i kahiwānanao nā ʻano kumukūʻai pākaukau sodium-ion i nā makahiki 5-10 e hiki mai ana a i ʻoleka loiloi hihia hoʻohanano nā ʻoihana kikoʻī (e laʻa, nā EV, nā wahi mālama paʻa)?
