Cov roj teeb khov kho yog ib hom roj teeb uas siv cov electrodes khov kho thiab electrolytes, tsis zoo li cov kua lossis polymer gel electrolytes siv rau hauv cov roj teeb lithium-ion ib txwm muaj. Lawv muaj zog ntau dua, lub sijhawm them sai dua, thiab kev nyab xeeb zoo dua piv rau cov roj teeb ib txwm muaj.
Cov roj teeb khov kho puas siv lithium?
Yog lawm, tam sim no feem ntau cov roj teeb solid-state uas tam sim no tab tom tsim kho siv lithium ua lub ntsiab lus tseem ceeb.
Muaj tseeb tiag, cov roj teeb solid-state siv tau ntau yam khoom siv ua electrolyte, suav nrog lithium. Txawm li cas los xij, cov roj teeb solid-state kuj siv tau lwm yam khoom siv xws li sodium, sulfur, lossis ceramics ua electrolyte.
Feem ntau, kev xaiv cov khoom siv electrolyte nyob ntawm ntau yam xws li kev ua tau zoo, kev nyab xeeb, tus nqi, thiab kev muaj. Cov roj teeb lithium solid-state yog cov thev naus laus zis zoo rau kev khaws cia lub zog tiam tom ntej vim lawv lub zog ceev ceev, lub neej ntev, thiab kev nyab xeeb zoo dua.
Cov roj teeb khov kho ua haujlwm li cas?
Cov roj teeb khov kho siv cov electrolyte khov kho es tsis yog cov electrolyte kua los hloov cov ions ntawm cov electrodes (anode thiab cathode) ntawm lub roj teeb. Cov electrolyte feem ntau yog ua los ntawm cov khoom siv ceramic, iav lossis polymer uas ruaj khov thiab conductive.
Thaum lub roj teeb solid-state raug them, cov electrons raug rub tawm ntawm cathode thiab thauj mus los ntawm cov electrolyte solid mus rau qhov anode, tsim kom muaj kev ntws ntawm tam sim no. Thaum lub roj teeb raug tso tawm, qhov kev ntws ntawm tam sim no raug thim rov qab, nrog cov electrons txav mus los ntawm qhov anode mus rau cathode.
Cov roj teeb khov kho muaj ntau qhov zoo dua li cov roj teeb ib txwm muaj. Lawv muaj kev nyab xeeb dua, vim tias cov electrolyte khov kho tsis yooj yim xau lossis tawg dua li cov electrolytes kua. Lawv kuj muaj zog ntau dua, txhais tau tias lawv tuaj yeem khaws cia ntau lub zog hauv qhov ntim me dua.
Txawm li cas los xij, tseem muaj qee qhov teeb meem uas yuav tsum tau daws nrog cov roj teeb khov kho, suav nrog cov nqi tsim khoom siab thiab muaj peev xwm tsawg. Kev tshawb fawb tseem tab tom ua kom tsim cov khoom siv electrolyte khov kho zoo dua thiab txhim kho kev ua haujlwm thiab lub neej ntawm cov roj teeb khov kho.
Muaj pes tsawg lub tuam txhab roj teeb khov kho tam sim no hauv kev ua lag luam?
Muaj ntau lub tuam txhab uas tam sim no tab tom tsim cov roj teeb khov kho:
1. Quantum Scape:Ib lub tuam txhab tshiab uas tau tsim tsa xyoo 2010 thiab tau txais kev nqis peev los ntawm Volkswagen thiab Bill Gates. Lawv hais tias lawv tau tsim lub roj teeb khov kho uas tuaj yeem ua rau lub tsheb fais fab khiav tau ntau dua 80%.
2. Toyota:Lub tuam txhab tsim tsheb Nyij Pooj tau ua haujlwm rau cov roj teeb khov kho tau ntau xyoo thiab lub hom phiaj yog kom muaj lawv hauv kev tsim khoom thaum ntxov xyoo 2020.
3. Fisker:Ib lub tuam txhab pib tsim tsheb fais fab khoom kim heev uas koom tes nrog cov kws tshawb fawb ntawm UCLA los tsim cov roj teeb khov kho uas lawv hais tias yuav ua rau lawv lub tsheb muaj zog dua.
4. BMW:Lub tuam txhab tsim tsheb German kuj tseem tab tom ua haujlwm rau cov roj teeb khov kho thiab tau koom tes nrog Solid Power, lub tuam txhab pib ua lag luam hauv Colorado, los tsim lawv.
5. Samsung:Lub tuam txhab hluav taws xob Kauslim loj tab tom tsim cov roj teeb khov kho rau kev siv hauv cov xov tooj ntse thiab lwm yam khoom siv hluav taws xob.
Yog tias cov roj teeb khov kho yuav raug siv rau kev khaws cia hnub ci yav tom ntej?
Cov roj teeb khov kho muaj peev xwm hloov pauv lub zog cia rau kev siv lub hnub ci. Piv rau cov roj teeb lithium-ion ib txwm muaj, cov roj teeb khov kho muaj zog ntau dua, lub sijhawm them sai dua, thiab kev nyab xeeb ntau dua. Lawv siv rau hauv cov txheej txheem cia lub hnub ci tuaj yeem txhim kho kev ua haujlwm zoo, txo cov nqi, thiab ua rau lub zog rov ua dua tshiab yooj yim dua. Kev tshawb fawb thiab kev txhim kho hauv cov thev naus laus zis roj teeb khov kho tseem tab tom ua, thiab nws muaj peev xwm hais tias cov roj teeb no yuav dhau los ua qhov kev daws teeb meem tseem ceeb rau kev cia lub hnub ci yav tom ntej. Tab sis tam sim no, cov roj teeb khov kho yog tsim tshwj xeeb rau kev siv EV.
Toyota tab tom tsim cov roj teeb solid-state los ntawm Prime Planet Energy & Solutions Inc., ib qho kev koom tes nrog Panasonic uas tau pib ua haujlwm thaum lub Plaub Hlis 2020 thiab muaj kwv yees li 5,100 tus neeg ua haujlwm, suav nrog 2,400 tus ntawm ib lub tuam txhab hauv Suav teb tab sis tseem muaj kev tsim khoom tsawg heev tam sim no thiab vam tias yuav muaj ntau dua los ntawm xyoo 2025 thaum lub sijhawm zoo.
Cov roj teeb khov kho yuav muaj thaum twg?
Peb tsis muaj xov xwm tshiab thiab cov xov xwm tshiab txog kev muaj cov roj teeb solid-state. Txawm li cas los xij, ntau lub tuam txhab tab tom ua haujlwm los tsim cov roj teeb solid-state, thiab qee lub tau tshaj tawm tias lawv npaj yuav tso tawm lawv los ntawm xyoo 2025 lossis tom qab ntawd. Txawm li cas los xij, nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias lub sijhawm rau kev muaj cov roj teeb solid-state yuav txawv nyob ntawm ntau yam, xws li kev cov nyom ntawm thev naus laus zis thiab kev pom zoo los ntawm cov cai.
