Ọnụ ego na nyocha akụrụngwa nke batrị sodium-ion?

1. Ọnụ ihe eji eme ihe

Sodium (Na)

• Uru: Sodium bụ ihe nke isii kachasị na mbara ụwa ma dị ngwa ngwa na mmiri mmiri na nnu.
• Ọnụ: Dị oke ala ma e jiri ya tụnyere lithium - sodium carbonate na-abụkarị$40- $60 kwa ton, mgbe lithium carbonate bụ$13,000–$20,000 kwa ton(dị ka nke data ahịa na nso nso a).
• Mmetụta: Isi uru na-eri na nnweta akụrụngwa.

Ihe onwunwe Cathode

• Batrị sodium-ion na-ejikarị:
  • Analogs blue Prussian (PBAs)
  • Sodium iron phosphate (NaFePO₄)
  • Oxides dị n'ụdị (dịka, Na₀.₆₇[Mn₀.₅Ni₀.₃Fe₀.₂] O₂)
• Ihe ndị a bụdị ọnụ ala karịa lithium cobalt oxide ma ọ bụ nickel manganese cobalt (NMC)eji na batrị Li-ion.

Ihe eji eme anode

• Carbon siri ikebụ ihe na-emekarị anode.
• Ọnụ: Dị ọnụ ala karịa graphite ma ọ bụ silicon eji na batrị Li-ion, n'ihi na ọ nwere ike si na biomass (dịka ọmụmaatụ, shells aki oyibo, osisi).

Akụrụngwa na akụrụngwa

• Ndakọrịta: Sodium-ion batrị nrụpụta bụdakọtara na ahịrị mmepụta batrị lithium-ion dị ugbu a, Na-ebelata CAPEX (Akụkụ Isi Obodo) maka ndị na-emepụta mgbanwe ma ọ bụ scaling.
• Electrolyte na Separator akwụ ụgwọ: Yiri Li-ion, ọ bụ ezie na njikarịcha maka Na-ion ka na-agbanwe.

Mmetụta Njupụta Ike

• Batrị sodium-ion nwereobere ike njupụta(~ 100–160 Wh/kg vs. 180–250 Wh/kg maka Li-ion), nke nwere ike ịbawanye ọnụ ahịakwa nkeji nke ike echekwara.

Sodium

• Nnọpụiche Geopolitical: A na-ekesa sodium n'ụwa niile, ọ naghị etinyekwa ya na mpaghara esemokwu ma ọ bụ nke nwere naanị ya dị ka lithium, cobalt, ma ọ bụ nickel.
• Ndogide: High - mmịpụta na ucha nwereobere mmetụta gburugburu ebe obibikarịa ngwuputa lithium (karịsịa site na isi mmalite nkume siri ike).

Lithium

• Ihe ize ndụ akụrụngwa: Ihu lithiummgbanwe ọnụahịa, ụdọ ọkọnọ mmachi, naọnụ ahịa gburugburu ebe obibi dị elu(mmiri na-agbasi ike site na brines, ikuku CO₂).
