Tawm tsam lub backdrop ntawm lub ntiaj teb hluav taws xob hloov thiab cov hom phiaj ntaulbon ", raws li lub zog sib xyaw, tau nce siab. Nyob rau hauv xyoo tsis ntev los no, sodium-ion roj teeb (cov nqi) tau tawm los ntawm chaw soj ntsuam kev lag luam ua raws li cov roj teeb lithium-ion.
Cov Ntaub Ntawv Yooj Yim Txog Sodium-ion roj teeb
Sodium-ion roj teeb yog hom roj teeb thib ob (rechargeable) uas siv Sodium ions (NACH) ua cov neeg nqa khoom noj (naiv) ua tus nqa khoom them nyiaj. Lawv lub ntsiab cai ua haujlwm zoo ib yam li cov roj teeb lithium-ion: thaum them nyiaj thiab anode ntawm electrolyte, enabling zog cia thiab tso tawm.
·Cov Ntaub Ntawv Tseem Ceeb
·Tshuab Paub Txog Kev Loj Hlob: Kev tshawb fawb pib thaum xyoo 1980s, thiab cov txheej txheem tsis ntev los no tau txhim kho lub zog thiab lub voj voog ua haujlwm, ua rau kev ua haujlwm nce ntxiv.
Sodium-ion roj teeb thiab cov roj teeb lithium-ion: sib txawv ntawm qhov sib txawv thiab cov txiaj ntsig zoo
Txawm hais tias sodium-ion teeb meem qhia cov teeb meem zoo sib xws nrog cov roj teeb lithium-ion, lawv txawv hauv cov khoom siv thiab cov ntawv thov kev xaiv:
| Kev Sib Piv | Sodium-ion roj teeb | Lithium-ion roj teeb |
| Kev muaj peev xwm muaj ntau | Sodium yog muaj ntau (2.75% nyob rau hauv lub ntiaj teb crust) thiab dav faib | Lithium yog tsawg (0.0065%) thiab thaj chaw muaj ntau |
| Tus nqi | Cov khoom siv raw qis, cov khoom siv tsis khov | Cov nqi siab luv rau cov lithium, cobalt, thiab lwm yam ntaub ntawv, nce siab rau kev txawv teb chaws |
| Lub Zog Ntiab | Qis dua (120-160 wh / kg) | Siab dua (200-300 wh / kg) |
| Tsawg-qhov kub ua tau zoo | Kev muaj peev xwm khaws cia> 80% ntawm -20 ℃ | Tsis zoo ua tau zoo nyob rau hauv tsawg kub, muaj peev xwm degrades yooj yim |
| Kev xyuas xim | Siab thermal stability, ntau tiv taus ntau dhau / tawm | Yuav tsum tau tswj nruj ntawm kev tswj hwm thermal khiav tawm |
Cov tub ntxhais zoo ntawm sodium-ion roj teeb:
1.Tus nqi qis thiab cov khoom siv nyob rau hauv: Sodium yog dav nyob rau hauv seaterater thiab zaub mov, txo kev cia siab rau cov me me thiab txo qis nqi los ntawm 30% -40%.
2. Kev nyab xeeb thiab ib puag ncig ua phooj ywg: Pub dawb los ntawm cov khoom muaj kuab paug hnyav, sib xws nrog kev nyab xeeb electrolyte system, thiab haum rau loj-teev lub zog cia.
3. POTERE HEEV NTSIAB: Kev ua tau zoo heev nyob rau hauv qis-kub ib puag ncig, zoo tagnrho rau cov cheeb tsam txias lossis sab nraum zoov cia lub zog.
Daim Ntawv Thov Kev Pab Cuam ntawm Sodium-ion roj teeb
Nrog cov txheej txheem thev naus laus zis, sodium-ion roj teeb qhia cov peev xwm zoo hauv cov chaw hauv qab no:
1. :
Raws li kev daws teeb meem haub rau cua thiab hnub ci zog, sodium-ion roj teeb thiab ntev npaum li cas txo tus nqi hluav taws xob (ntsws) thiab pab txhawb phiaj hniav.
2. Tsawg-ceev hluav taws xob tsheb thiab ob lub log tsheb:
Hauv cov xwm txheej nrog cov nqi hluav taws xob qis dua (piv txwv li, cov tsheb hluav taws xob, cov roj teeb hluav taws xob ntxiv tuaj yeem hloov roj teeb thiab kev khwv nyiaj txiag ib puag ncig thiab nyiaj txiag ib puag ncig thiab nyiaj txiag ib puag ncig thiab kev khwv nyiaj txiag.
3. Backup Lub Zog Thiab Cov Chaw Nres Tsheb Hluav Taws Xob Chaw Cia:
Lawv qhov kev ua tau ntau qhov kev ua tau ua rau lawv haum rau kev siv hluav taws xob rov qab xav tau kev sib txuas lus hauv paus thiab cov ntaub ntawv cov chaw.
Kev tsim kho yav tom ntej
Kev lag luam kev lag luam kwv yees tias kev lag luam tshaj plaws hauv ntiaj teb
·Cov Khoom Siv Tawm Tshiab: Tsim cov khoom siv hluav taws xob siab (piv txwv li, o3-hom txheej txheem oxidesed oxides) thiab ntev-lub neej anode cov khoom siv kom nce lub zog ntom ntom saum 200 wh / kg.
·Txheej txheem optimization: Siv roj teeb cov roj teeb ntau lawm los ntsuas cov khoom siv roj teeb sodium-ion thiab ntxiv txo cov nqi.
·Daim Ntawv Thov nthuav dav: Ua kom tiav cov roj teeb lithium-ion los tsim lub zog sib txawv cia tshuab hluav taws xob cia tshuab.
