Wow, qhov kev tsim tawm no yuav dhau los ua cov cai ntawm kev ua si hauv ntiaj teb kev lag luam tshiab kev lag luam! Lub Ob Hlis 12, 2025, the International Cov Ntawv Xov Xwm Thoob Ntiaj Teb tshaj tawm kev sib tawg tawm. Pab neeg ntawm Peng Huisheng / Gao Yue los ntawm Fudan University hauv Suav Teb tsim cov tshiabLithium roj teeb "rejuvenation" thev naus laus zis, Rhuav cov qauv tsim qauv ntawm cov roj teeb lithium rau ntau tshaj 30 xyoo, uas tuaj yeem txuas lub roj teeb lub neej los ntawm ntau dua 10 zaug! Ib qho zoo tib yam lithium iron phosium hlau phosphate roj teeb tseem muaj kev tswj hwm 96% ntawm nws lub peev xwm tom qab 11,818 tus nqi thiab tawm mus ncig! Koj paub, cov roj teeb lithium tam sim no ntawm kev ua lag luam yog siv rau 1000-2000 zaug.
Qhov no txhais tau li cas? Ib teela siv los hloov nws lub roj teeb txhua 6-8 xyoos, tab sis tam sim no nws tuaj yeem tsav rau 60 xyoo tsis tas yuav hloov nws! Koj iPhone tuaj yeem them thiab tso tawm 10,000 zaus yam tsis tau poob zog!
Kev tshoov siab rau kev siv roj teeb tshuab los ntawm tib neeg kev kho
Qhov no yog qhov dab tsi tshwm sim tau yug los?
Cia li nyiam kho tib neeg cov kab mob, peb tsom rau cov tub ntxhais cov roj teeb thaum tiv thaiv Gao Yue, tus kws tshawb fawb ntawm Fudan University.
Keeb xeeb, qhov laj thawj tseem ceeb rau "kev laus" ntawm cov roj teeb lithium yog qhov ploj ntawm lithium. Ib yam li qhov tsis muaj qee yam kev noj zaub mov hauv tib neeg lub cev tuaj yeem ua rau muaj mob, roj teeb kuj tseem tuaj yeem ua rau poob qis vim kev ua tsis zoo. Lub tswv yim tawg ntawm pab pawg yog: Peb puas tuaj yeem rov ua dua cov kab mob lim hiam uas ploj lawm hauv lub roj teeb zoo li kev txhaj tshuaj rau tus neeg mob?
AI pab tawg ntawm cov roj teeb tseem ceeb ntsuas thev naus laus zis
Txawm li cas los xij, nrhiav qhov tsim nyog "kev txhaj tshuaj" tsis yog txoj haujlwm yooj yim. Cov cab kuj no yuav tsum tau sib ntsib yuav luag tau raws li yuav luag siv txoj hlua khi thiab tshuaj lom neeg:
- Muaj cov kev ua kom tsim nyog hauv tshuab hluav taws xob thiab kev txiav txim siab voltage ntau.
- Tsim los solubility hauv electrolyte.
- Muaj cov cua zoo thiab tshuaj muaj peev xwm ruaj khov.
- Tsim nyog acidity, alkalinity, thiab tshuaj tiv thaiv kinetics.
- Lub decomposition cov khoom yuav tsum muaj kev nyab xeeb thiab tsis muaj dab tsi.
- Qhov tseem ceeb tshaj plaws, nws yuav tsum yog pheej yig thiab yooj yim ntsuas ntau lawm.
Kev txawj ntse dag ntxias cov khoom tseem ceeb
Tsis muaj ib qho ua ntej ua raws, pab pawg tshawb fawb tig mus rau kev txawj ntse. They digitized the molecular properties and used machine learning to find answers from a huge amount of organic chemistry, electrochemistry and materials engineering data.
Lub zog ua haujlwm tau them tawm! Tom qab 4 xyoo ntawm kev ua haujlwm nyuaj, lawv thaum kawg pom qhov zoo tshaj plaws kev daws teeb meem: CF3YO2LI (Lithium Trifluoromomomomomomomomomomomomimethanate). Cov molecule no zoo li cov neeg thauj me me, nqa cov tshuab hluav taws xob me me ntawm ib qhov kawg thiab kev nyab xeeb rho tawm ntawm lwm qhov kawg tom qab kev thauj mus los.
Qhov kev sim ua rau poob siab!
Hauv kev sim, lub roj teeb uas tau txais txoj kev kho mob no "tseem muaj kev ua tau zoo nyob ze rau lub Hoobkas qib txawm tias yog 60000 tus nqi thiab tawm mus ncig. Qhov no tsis yog txuas ntxiv roj teeb lub neej, tab sis kuj tseem muab kev daws teeb meem kev daws teeb meem los daws cov teeb meem ntawm cov khib nyiab loj.
Txawm hais tias cov thev naus laus zis no tau qhib txhua txoj kev tshiab tshiab:
Ua raws lithium dawb canhode roj teeb system nrog ib qho hluav taws xob ntawm 3.0V thiab lub zog ntom txog li 1192 wh / kg.
Tsim cov organic sulfurized polyacrylonitrile Cathia roj teeb nrog lub zog ntom ntawm 388 wh / kg.
Cuam tshuam ntau dua
Qhov kev sib tsoo no yuav hloov pauv cov cai ntawm kev ua si hauv kev lag luam hluav taws xob tshiab:
Nws yuav txo tus nqi ntawm kev siv cov nqi hluav taws xob, muaj ntau txoj kev paug ib puag ncig los ntawm kev siv roj teeb ib puag ncig, thiab qhib cov tswv yim tshiab rau cov roj teeb tshiab; Qhov kev zoo siab tshaj plaws yog tus nqi ntawm cov thev naus laus zis yog qhov xav tau ntau dua 10% ntawm tag nrho cov roj teeb, uas txhais tau tias nws muaj peev xwm ua lag luam loj.
Raws li cov neeg tshawb fawb Gao Yue hais tias: txawm nws yuav tsum tau ua kom muaj roj teeb loj dua lossis tiv thaiv kom ib puag ncig kev tso tseg thiab ib puag ncig kev kho mob "muab kev daws teeb meem kev daws teeb meem. Qhov kev tshawb fawb no tsis yog qhia txog Tuam Tshoj lub zog tshiab hauv lub cev ntawm lub zog tshiab, tab sis kuj tseem muaj lub zog tshiab los ntawm lub sijhawm tshiab. Nyob rau yav tom ntej ze, "roj teeb ntxhov siab vim" yuav dhau los ua keeb kwm. Cia peb tos ntsoov rau kev ua lag luam ntawm qhov kev hloov thev naus laus zis kom sai li sai tau!
