Tawm tsam keeb kwm yav dhau los ntawm kev hloov pauv hluav taws xob thoob ntiaj teb thiab "dual-carbon" cov hom phiaj, roj teeb thev naus laus zis, ua lub zog tseem ceeb ntawm lub zog cia, tau txais kev saib xyuas tseem ceeb. Nyob rau hauv xyoo tas los no, cov roj teeb sodium-ion (SIBs) tau tshwm sim los ntawm lub chaw soj nstuam mus rau industrialization, dhau los ua ib qho kev cia siab ntawm lub zog cia tom qab lithium-ion roj teeb.
Cov ntaub ntawv tseem ceeb ntawm Sodium-ion roj teeb
Sodium-ion roj teeb yog ib hom roj teeb nruab nrab (rechargeable) uas siv sodium ions (Na⁺) ua cov khoom thauj. Lawv txoj hauv kev ua haujlwm zoo ib yam li cov roj teeb lithium-ion: thaum lub sijhawm them thiab tawm, sodium ions shuttle ntawm cathode thiab anode los ntawm electrolyte, ua kom lub zog cia thiab tso tawm.
·Cov ntaub ntawv tseem ceeb: Cov cathode feem ntau yog siv cov txheej txheej oxides, polyanionic compounds, los yog Prussian xiav analogs; lub anode feem ntau yog tsim los ntawm cov roj carbon tawv lossis cov roj carbon mos; cov electrolyte yog sodium ntsev tov.
·Tshuab maturity: Kev tshawb fawb tau pib nyob rau xyoo 1980s, thiab kev nce qib hauv cov ntaub ntawv thiab cov txheej txheem tsis ntev los no tau txhim kho lub zog ceev thiab lub voj voog lub neej, ua rau kev lag luam nce ntxiv.
Sodium-ion roj teeb vs. Lithium-ion roj teeb: Qhov txawv thiab qhov zoo
Txawm hais tias cov roj teeb sodium-ion muaj cov qauv zoo sib xws nrog cov roj teeb lithium-ion, lawv sib txawv hauv cov khoom siv thiab cov xwm txheej:
| Sib piv Dimension | Sodium-ion roj teeb | Lithium-ion roj teeb |
| Kev Muaj Peev Xwm Ntau | Sodium muaj ntau (2.75% nyob rau hauv lub ntiaj teb crust) thiab dav faib | Lithium tsis tshua muaj (0.0065%) thiab geographically concentrated |
| Nqi | Tsawg tus nqi raw khoom, cov saw hlau ruaj khov dua | Tus nqi siab volatility rau lithium, cobalt, thiab lwm yam ntaub ntawv, cia siab rau imports |
| Zog Ceev | Tsawg (120-160 Wh / kg) | Siab (200-300 Wh / kg) |
| Low-Temperature Performance | Lub peev xwm tuav tau> 80% ntawm -20 ℃ | Kev ua haujlwm tsis zoo hauv qhov kub thiab txias, muaj peev xwm degrades yooj yim |
| Kev nyab xeeb | High thermal stability, ntau resistant rau overcharge / tawm | Yuav tsum muaj kev tswj xyuas nruj ntawm thermal runaway txaus ntshai |
Core Advantages ntawm Sodium-ion roj teeb:
1.Tus nqi qis thiab cov peev txheej Sustainability: Sodium muaj dav hauv cov dej hiav txwv thiab cov zaub mov, txo kev cia siab ntawm cov hlau tsis tshua muaj thiab txo cov nqi mus sij hawm ntev los ntawm 30% -40%.
2. Kev nyab xeeb siab thiab Environmental Friendliness: Dawb los ntawm hnyav hlau muaj kuab paug, sib xws nrog kev ruaj ntseg electrolyte systems, thiab haum rau loj-scale cia.
3. Wide Temperature Range Adaptability: Kev ua tau zoo heev nyob rau hauv ib puag ncig uas tsis tshua muaj kub, zoo tagnrho rau cov cheeb tsam txias lossis sab nraum zoov lub zog cia.
Daim ntawv thov Prospects ntawm Sodium-ion roj teeb
Nrog rau kev txhim kho thev naus laus zis, cov roj teeb sodium-ion qhia tau tias muaj peev xwm zoo hauv cov hauv qab no:
1. Loj-Scale Energy Storage Systems (ESS):
Raws li kev daws teeb meem ntxiv rau cua thiab hnub ci zog, cov roj teeb sodium-ion 'tus nqi qis thiab kev ua neej ntev tuaj yeem txo qis tus nqi hluav taws xob (LCOE) thiab pab txhawb cov phiajcim ncov shaving.
2. Tsawg-Speed Electric Tsheb thiab Ob-Wheelers:
Hauv cov xwm txheej uas yuav tsum muaj lub zog qis dua (piv txwv li, lub tsheb kauj vab hluav taws xob, tsheb thauj khoom), cov roj teeb sodium-ion tuaj yeem hloov cov roj lead-acid, muab cov txiaj ntsig ib puag ncig thiab kev lag luam.
3. Thaub qab fais fab thiab Base chaw nres tsheb zog cia:
Lawv qhov kev ua tau zoo ntawm qhov kub thiab txias ua rau lawv haum rau cov kev xav tau ntawm lub zog thaub qab hauv cov ntawv thov kub-sensitive xws li kev sib txuas lus hauv paus chaw nres tsheb thiab cov chaw khaws ntaub ntawv.
Kev Txhim Kho Yav Tom Ntej
Kev lag luam kwv yees kwv yees tias kev lag luam thoob ntiaj teb sodium-ion roj teeb yuav tshaj $ 5 nphom los ntawm 2025 thiab ncav cuag 10% -15% ntawm lithium-ion roj teeb kev lag luam los ntawm 2030. Cov lus qhia yav tom ntej muaj xws li:
·Material Innovation: Tsim cov cathodes muaj peev xwm (piv txwv li, O3-hom txheej txheej oxides) thiab cov khoom siv lub neej ntev anode kom muaj zog ceev tshaj 200 Wh / kg.
·Txheej txheem Optimization: Leveraging mature lithium-ion roj teeb cov kab ntau lawm kom scale li sodium-ion roj teeb raug thiab txo nqi ntxiv.
