Tam sim no, tsis muaj kev daws teeb meem rau qhov teeb meem ntawm lub xeev cov roj teeb tsis sib txuas vim lawv qhov kev tshawb fawb thiab kev loj hlob tsis tu ncua, uas nthuav tawm ntau yam kev daws teeb meem tsis tau daws teeb meem, kev lag luam, thiab kev lag luam. Muab cov kev txwv tam sim no, kev tsim khoom loj tseem yog lub hom phiaj nyob deb, thiab cov roj teeb uas muaj zog tseem tsis tau muaj nyob hauv khw.
Dab tsi yog qhov cuam tshuam rau Solid State Battery Development?
Cov roj teeb hauv lub xeevSiv cov khoom siv electrolyte es tsis txhob siv cov kua electrolyte pom hauv ib txwm muajlithium-ion roj teeb. Cov roj teeb lithium ua kua muaj xws li plaub yam tseem ceeb: qhov zoo electrode, tsis zoo electrode, electrolyte, thiab cov separator. Hauv qhov sib piv, cov roj teeb hauv lub xeev siv cov khoom siv electrolyte es tsis txhob siv cov kua sib xyaw ua ke.
Muab lub peev xwm zoo ntawm cov khoom siv hluav taws xob hauv lub xeev no, vim li cas ho tsis tau qhia rau lub khw? Vim tias kev hloov pauv ntawm chav kuaj mus rau kev lag luam ntsib ob qho kev sib tw:technical feasibilitythiabeconomic viability.
- 1. Technical Feasibility: Lub hauv paus ntawm lub roj teeb uas muaj zog yog hloov cov kua electrolyte nrog cov khoom electrolyte. Txawm li cas los xij, kev tswj xyuas kev ruaj ntseg ntawm qhov sib cuam tshuam ntawm cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob ua rau muaj kev sib tw tseem ceeb. Kev sib cuag tsis txaus tuaj yeem ua rau muaj zog tiv thaiv, yog li txo cov roj teeb ua haujlwm. Tsis tas li ntawd, cov khoom electrolytes raug kev txom nyem los ntawm qis ionic conductivity thiab qeeb qeeblithium ionkev txav mus los, ua rau qeeb qeeb thiab tso tawm nrawm.
- Ntxiv mus, cov txheej txheem tsim khoom yog complex. Piv txwv li, sulfide khoom electrolytes yuav tsum tau tsim nyob rau hauv inert gas tiv thaiv kom tsis txhob ya raws nyob rau hauv cov huab cua uas tsim cov pa phem. Tus nqi siab thiab cov txheej txheem technically nyuaj tam sim no cuam tshuam qhov ua tau ntawm kev tsim khoom loj. Tsis tas li ntawd, kev sim kuaj mob feem ntau txawv ntawm qhov chaw nyob hauv ntiaj teb tiag tiag, ua rau ntau lub thev naus laus zis tsis tuaj yeem ua tiav cov txiaj ntsig xav tau.
- 2. Economic Viability:Txhua lub xeev cov roj teeb nqi yog ob peb zaug ntau dua li cov roj teeb lithium ib txwm muaj thiab txoj hauv kev rau kev lag luam yog fraught nrog teeb meem. Txawm hais tias nws muaj kev nyab xeeb dua hauv txoj kev xav, hauv kev xyaum, cov khoom siv electrolyte tuaj yeem tawg ntawm qhov kub thiab txias, ua rau txo qis kev ua haujlwm ntawm roj teeb lossis txawm tias tsis ua haujlwm.
- Tsis tas li ntawd, dendrites tuaj yeem tsim thaum lub sij hawm them nyiaj thiab tso tawm cov txheej txheem, tho qhov sib cais, ua rau luv luv, thiab txawm tias tawg, ua rau kev nyab xeeb thiab kev ntseeg siab yog qhov teeb meem tseem ceeb. Tsis tas li ntawd, thaum cov txheej txheem tsim khoom me me tau nce rau kev tsim khoom, cov nqi yuav nce siab.
Thaum twg Cov Roj Teeb Tseem Ceeb Yuav Tuaj Txog?
Cov roj teeb hauv lub xeev tau xav tias yuav pom cov ntawv thov tseem ceeb hauv cov khoom siv hluav taws xob high-end, tsheb hluav taws xob me me (EVs), thiab kev lag luam nrog kev ua haujlwm nruj thiab kev nyab xeeb, xws li aerospace. Txawm li cas los xij, cov roj teeb-lub xeev tam sim no muaj nyob rau hauv kev ua lag luam tseem nyob rau theem pib ntawm lub tswv yim kev lag luam.
Cov tuam txhab tsheb tseem ceeb thiablithium roj teeb manufacturerszoo li SAIC Motor, GAC-Toyota, BMW, CATL, BYD, thiab EVE tau nquag tsim cov roj teeb uas muaj zog. Txawm li cas los xij, raws li lawv cov sijhawm tsim tawm tshiab, nws tsis zoo li tias tag nrho cov khoom loj ntawm cov roj teeb hauv lub xeev yuav pib ua ntej 2026-2027 thaum ntxov. Txawm tias Toyota yuav tsum tau hloov kho nws lub sijhawm ntau zaus thiab tam sim no npaj yuav pib ntau lawm hauv 2030.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias lub sijhawm muaj rau cov roj teeb uas muaj zog tuaj yeem sib txawv vim muaj ntau yam xws li cov teeb meem thev naus laus zis thiab kev pom zoo rau kev tswj hwm.
Cov ntsiab lus tseem ceeb rau cov neeg siv khoom
Thaum ze saib xyuas kev nce qib hauv covsolid state lithium roj teebteb, nws yog ib qho tseem ceeb rau cov neeg siv khoom kom ceev faj thiab tsis txhob swayed los ntawm superficially dazzling cov ntaub ntawv. Txawm hais tias kev tsim kho tshiab tiag tiag thiab kev ua haujlwm thev naus laus zis yog tsim nyog xav txog, lawv xav tau sijhawm rau kev txheeb xyuas. Cia peb cia siab tias thaum thev naus laus zis nce qib thiab kev lag luam loj hlob tuaj, kev ruaj ntseg thiab pheej yig dua tshiab zog daws teeb meem yuav tshwm sim yav tom ntej.
