Wow, qhov kev tsim kho no tuaj yeem hloov pauv tag nrho cov cai ntawm kev ua si hauv lub ntiaj teb tshiab lub zog kev lag luam! Thaum Lub Ob Hlis 12, 2025, cov ntawv xov xwm thoob ntiaj teb sab saum toj Nature tau luam tawm kev hloov pauv hloov pauv. Pab neeg ntawm Peng Huisheng / Gao Yue los ntawm Fudan University hauv Suav teb tau tsim ib qho tshiablithium roj teeb "rejuvenation" technology, rhuav tshem cov qauv tsim qauv ntawm cov roj teeb lithium rau ntau tshaj 30 xyoo, uas tuaj yeem txuas lub roj teeb lub neej ntau dua 10 zaug! Lub roj teeb lithium hlau phosphate zoo tib yam tseem tuav 96% ntawm nws lub peev xwm tom qab 11,818 tus nqi thiab tawm mus! Koj paub, cov roj teeb lithium tam sim no nyob rau hauv kev ua lag luam yog siv rau 1000-2000 zaug.
Qhov no txhais li cas? Tesla tau siv los hloov nws lub roj teeb txhua 6-8 xyoo, tab sis tam sim no nws tuaj yeem tsav tau 60 xyoo yam tsis tas yuav hloov nws! Koj lub iPhone tuaj yeem raug them thiab tso tawm 10,000 zaug yam tsis poob lub zog!
Kev tshoov siab rau kev kho roj teeb thev naus laus zis los ntawm kev kho tib neeg
Qhov kev tshawb pom txuj ci tseem ceeb no tau yug los li cas?
Ib yam li kev kho tib neeg cov kab mob, peb tsom mus rau kev kho cov teeb meem tseem ceeb ntawm cov roj teeb thaum tiv thaiv lawv cov khoom noj qab haus huv, "piav qhia Gao Yue, tus kws tshawb fawb ntawm Fudan University.
Keeb kwm, qhov laj thawj tseem ceeb rau "kev laus" ntawm lithium roj teeb yog qhov poob ntawm lithium ions. Ib yam li qhov tsis muaj qee yam khoom noj hauv tib neeg lub cev tuaj yeem ua rau muaj mob, cov roj teeb kuj tuaj yeem ua rau muaj kev poob qis vim kev noj zaub mov tsis txaus. Lub tswv yim zoo ntawm pab pawg yog: Peb puas tuaj yeem ntxiv cov lithium ions ploj hauv lub roj teeb zoo li muab kev txhaj tshuaj rau tus neeg mob?
AI pab cuam tshuam los ntawm cov roj teeb tseem ceeb ntsuas thev naus laus zis
Txawm li cas los xij, nrhiav qhov tsim nyog "txhaj tshuaj" tsis yog ib txoj haujlwm yooj yim. Cov cab kuj molecule no yuav tsum ua kom tau raws li yuav luag nruj zog ntawm lub cev thiab cov khoom siv tshuaj:
- Muaj qhov tsim nyog electrochemical kev ua si thiab decomposition voltage ntau yam.
- Tsim nyog solubility hauv electrolyte.
- Nws muaj huab cua ruaj khov thiab tshuaj lom neeg ruaj khov.
- Tsim nyog acidity, alkalinity, thiab cov tshuaj tiv thaiv kinetics.
- Cov khoom decomposition yuav tsum muaj kev nyab xeeb thiab tsis muaj mob.
- Qhov tseem ceeb tshaj plaws, nws yuav tsum pheej yig thiab yooj yim rau scale nce ntau lawm.
Artificial txawj ntse nrhiav tau cov ntaub ntawv tseem ceeb
Tsis muaj qhov ua ntej ua raws, pab pawg tshawb fawb tau tig mus rau kev txawj ntse. Lawv digitized cov khoom molecular thiab siv tshuab kev kawm los nrhiav cov lus teb los ntawm ntau cov organic chemistry, electrochemistry thiab cov ntaub ntawv engineering cov ntaub ntawv.
Txoj hauj lwm nyuaj tau them! Tom qab 4 xyoos ntawm kev ua haujlwm nyuaj, lawv thaum kawg pom cov tshuaj zoo tshaj plaws: CF3SO2Li (lithium trifluoromethanesulfonate). Cov molecule no zoo li cov khoom thauj me me, nqa lithium electrons ntawm ib qho kawg thiab tso tawm kom zoo li cov pa roj ntawm lwm qhov kawg tom qab kev thauj mus los tiav.
Cov txiaj ntsig kev sim yog qhov xav tsis thoob!
Hauv kev sim, lub roj teeb uas tau txais qhov "kev kho qhov tseeb" tseem muaj qhov ua tau zoo nyob ze ntawm lub Hoobkas txawm tias tom qab 12000 txog 60000 tus nqi thiab tawm mus. Qhov no tsis tsuas yog txuas lub roj teeb lub neej, tab sis kuj tseem muab cov kev daws teeb meem ua tau los daws qhov teeb meem ntawm cov roj teeb loj loj uas muaj kuab paug.
Qhov zoo siab tshaj plaws yog tias qhov thev naus laus zis no tau qhib tag nrho cov peev txheej tshiab:
Ua raws li cov roj teeb lithium dawb cathode nrog lub zog ntawm 3.0V thiab lub zog ceev txog li 1192 Wh / kg.
Tsim cov organic sulfurized polyacrylonitrile cathode hnab roj teeb nrog lub zog ceev ntawm 388 Wh / kg.
Revolutionary cuam tshuam
Qhov kev ua txhaum no yuav hloov tag nrho cov cai ntawm kev ua si hauv kev lag luam hluav taws xob tshiab:
Nws yuav txo tau tus nqi ntawm kev siv lub tsheb fais fab, txo cov pa phem ib puag ncig los ntawm cov roj teeb scrapping, thiab qhib cov tswv yim tshiab rau kev tsim cov roj teeb tshiab; Qhov zoo siab tshaj plaws yog tias tus nqi ntawm cov thev naus laus zis no yog qhov tseem ceeb heev - nws yuav tsum suav nrog tsawg dua 10% ntawm tag nrho cov nqi roj teeb, uas txhais tau tias nws muaj peev xwm rau kev lag luam loj siv!
Raws li tus kws tshawb fawb Gao Yue tau hais tias: Txawm hais tias nws yuav txuas ntxiv roj teeb lub neej lossis tiv thaiv kev tso tseg loj thiab ib puag ncig muaj kuab paug, qhov "kev kho kom raug" no muab cov kev daws teeb meem ua tau. Qhov kev tshawb fawb no tsis tsuas yog qhia txog Tuam Tshoj lub zog tshiab hauv kev ua haujlwm ntawm lub zog tshiab, tab sis kuj qhia txog kev tuaj txog ntawm lub sijhawm tshiab. Nyob rau yav tom ntej, "kev ntxhov siab ntawm roj teeb" yuav dhau los ua keeb kwm. Cia peb tos ntsoov rau kev lag luam ntawm cov thev naus laus zis no kom sai li sai tau!
