Kev tshuaj xyuas tus nqi thiab cov peev txheej ntawm cov roj teeb sodium-ion?

1. Cov Nqi Khoom Siv Raw

Sodium (Na)

• Kev nplua miasSodium yog qhov muaj ntau tshaj plaws thib 6 hauv lub ntiaj teb lub plhaub thiab muaj nyob rau hauv dej hiav txwv thiab cov ntsev.
• Tus nqiQis heev piv rau lithium — sodium carbonate feem ntau yog$40–$60 ib tujthaum lithium carbonate yog$13,000–$20,000 ib tuj(raws li cov ntaub ntawv ua lag luam tsis ntev los no).
• Kev cuam tshuam: Qhov zoo tshaj plaws ntawm tus nqi hauv kev yuav khoom siv raw.

Cov Khoom Siv Cathode

• Cov roj teeb sodium-ion feem ntau siv:
  • Cov tshuaj Prussian xiav analogs (PBAs)
  • Sodium hlau phosphate (NaFePO4)
  • Txheej oxides (piv txwv li, Na₀.₆₇[Mn₀.₅Ni₀.₃Fe₀.₂]O₂)
• Cov ntaub ntawv no yogpheej yig dua li lithium cobalt oxide lossis nickel manganese cobalt (NMC)siv rau hauv cov roj teeb Li-ion.

Cov Khoom Siv Anode

• Cov pa roj carbon tawvyog cov khoom siv anode feem ntau.
• Tus nqiPheej yig dua li graphite lossis silicon siv rau hauv cov roj teeb Li-ion, vim nws tuaj yeem tau los ntawm biomass (piv txwv li, txiv maj phaub plhaub, ntoo).

2. Cov Nqi Tsim Khoom

Cov Khoom Siv thiab Cov Chaw Tsim Kho Vaj Tse

• Kev Sib Haum Xeeb: Kev tsim cov roj teeb sodium-ion yogfeem ntau sib xws nrog cov kab tsim roj teeb lithium-ion uas twb muaj lawm, txo qis CAPEX (Capital Expenditure) rau cov chaw tsim khoom hloov pauv lossis nthuav dav.
• Cov Nqi Electrolyte thiab SeparatorZoo ib yam li Li-ion, txawm hais tias kev ua kom zoo dua rau Na-ion tseem tab tom hloov zuj zus.

Kev Cuam Tshuam ntawm Lub Zog

• Cov roj teeb sodium-ion muajqis zog ceev(~100–160 Wh/kg piv rau 180–250 Wh/kg rau Li-ion), uas yuav ua rau tus nqi nce ntxivib chav ntawm lub zog khaws cia.
• Txawm li cas los xij,lub neej voj voogthiabkev nyab xeebcov yam ntxwv tuaj yeem them taus cov nqi ua haujlwm mus sij hawm ntev.

3. Kev Muaj Peev Xwm thiab Kev Ruaj Khov

Sodium

• Kev tsis koom nrog hauv kev nom kev tswv hauv ntiaj tebSodium muaj nyob thoob plaws ntiaj teb thiab tsis muaj ntau nyob rau hauv cov cheeb tsam uas muaj kev tsis sib haum xeeb lossis kev tswj hwm ib leeg xws li lithium, cobalt, lossis nickel.
• Kev ruaj khov: Muaj kev rho tawm thiab kev ua kom zoo dua qubtsawg dua qhov cuam tshuam rau ib puag ncigdua li kev khawb lithium (tshwj xeeb tshaj yog los ntawm cov pob zeb tawv).

Lithium

• Kev Pheej Hmoo ntawm Cov Khoom Siv: Cov ntsej muag lithiumkev hloov pauv ntawm tus nqi, cov saw hlau muab khoom tsawg, thiabcov nqi ib puag ncig siab(kev rho tawm ntawm cov dej ntsev uas siv dej ntau, cov pa CO₂).

4. Kev nthuav dav thiab kev cuam tshuam ntawm cov khoom xa tuaj

• Kev siv tshuab sodium-ion yogmuaj peev xwm nthuav dav heevvim yogmuaj cov khoom siv raw, pheej yig, thiabtxo cov kev txwv ntawm cov khoom xa tuaj.
• Kev saws txais ua pawg coobyuav txo qhov kev nyuaj siab rau cov saw hlau lithium, tshwj xeeb tshaj yog raukev khaws cia hluav taws xob nyob ruaj khov, tsheb ob lub log, thiab EVs qis qis.

Xaus lus

• Cov roj teeb Sodium-ionmuab ib qhopheej yig, ruaj khovlwm txoj hauv kev rau cov roj teeb lithium-ion, tshwj xeeb tshaj yog raukev cia khoom hauv grid, cov tsheb fais fab pheej yig, thiabkev lag luam uas tab tom loj hlob.
• Thaum thev naus laus zis loj hlob tuaj,kev ua haujlwm zoo ntawm kev tsim khoomthiabkev txhim kho zog ceevyuav tsum txo cov nqi ntxiv thiab nthuav cov ntawv thov.

Koj puas xav pom ib qhokev kwv yeesntawm cov nqi roj teeb sodium-ion hauv 5-10 xyoo tom ntej lossis ib qhokev tshuaj xyuas cov ntaub ntawv sivrau cov lag luam tshwj xeeb (piv txwv li, EVs, chaw cia khoom ruaj khov)?
