Beijing, Lub Plaub Hlis 25, 2026 - Pab pawg tshawb fawb coj los ntawm Tus Kws Tshawb Fawb Lu Lei los ntawm Lub Tsev Haujlwm ntawm Kev Tshawb Fawb Hlau, Suav Academy ntawm Kev Tshawb Fawb (IMR CAS), tau ua ib qho kev sib tw loj hauv cov khoom siv tooj liab, ua tiav "super copper foil" uas ua ke nrog ultra-siab zog, siab conductivity thiab zoo thermal stability. Cov khoom siv tshiab no, nrog lub zog tensile txog li 900MPa, tau tawg qhov ntev - sawv ntsug "daim duab peb sab tsis tau" ntawm lub zog, conductivity thiab thermal stability nyob rau hauv cov ntawv ci tooj liab, coj qhov muaj peev xwm tshiab rau kev kho dua tshiab ntawm lub zog cia kev lag luam.
Tooj liab muaj lub zog siab thiab toughness, withstands sab nraud cuam tshuam thiab kev co. Tsis zoo li tsawg- cov ntaub ntawv muaj zog, nws tsis txhob xoob lossis tawg, ua kom lub zog ruaj khov. Cov ntawv ci super tooj liab tsim tshiab siv cov txiaj ntsig no mus rau qib tshiab, ua tsaug rau nws qhov tshwj xeeb "gradient xaj nano-domain" microstructure tsim.
Qhov tseem ceeb ntawm kev tsim kho tshiab ntawm cov ntawv nyiaj super tooj liab yog nyob rau hauv kev tsim microstructural: pab pawg tshawb fawb tau tsim siab -density nano-domains nrog qhov nruab nrab loj ntawm tsuas yog 3 nanometers ntawm 10-micron tuab siab- purity tooj liab foil substrate los ntawm kev lag luam -compatible electrotic. Cov nano-domains no tau muab faib rau hauv ib ntus raws li qhov tuab ntawm cov ntawv ci tooj liab, zoo li "nano steel mesh" hauv cov khoom, uas ua kom muaj zog zoo thaum ua kom muaj kev ua tau zoo.
Cov ntaub ntawv ntsuam xyuas qhia tau hais tias lub zog tensile ntawm super tooj liab ntawv ci nce mus txog 900MPa, uas yog 1.5 mus rau 2 npaug ntawm cov ntawv ci tooj liab zoo tib yam (300-600MPa). Nyob rau tib lub sijhawm, nws cov hluav taws xob conductivity tseem nyob ntawm 90% IACS, uas yog kwv yees li ob zaug ntawm cov tsoos tooj liab alloys nrog tib lub zog. Qhov tseem ceeb tshaj, cov khoom siv qhia tau zoo heev thermal stability- nws qhov kev ua tau zoo yuav luag tsis hloov tom qab muab tso rau hauv chav sov li 180 hnub, daws qhov teeb meem ntawm kev ua tau zoo attenuation ntawm siab - cov khoom siv tooj liab vim nws tus kheej annealing.
Rau lub zog cia kev lag luam, uas muaj cov kev cai nruj ntawm cov khoom siv kev ntseeg siab, super tooj liab ntawv ci cov khoom siv zoo heev thiab ruaj khov muaj qhov zoo ntawm daim ntawv thov. Tooj liab muaj lub zog siab thiab toughness, withstands sab nraud cuam tshuam thiab kev co. Tsis zoo li tsawg- cov ntaub ntawv muaj zog, nws tsis txhob xoob lossis tawg, ua kom lub zog ruaj khov. Cov yam ntxwv no tshwj xeeb yog qhov tseem ceeb rau lub zog cia cov tshuab uas yuav tsum tau ua haujlwm ruaj khov rau lub sijhawm ntev, vim tias nws tuaj yeem tiv thaiv kev ntxhov siab los ntawm kev thauj mus los, kev teeb tsa thiab kev ua haujlwm txhua hnub, thiab zam kev nyab xeeb xws li lub davhlau ya nyob twg xoob, tawg thiab kub dhau los ntawm cov khoom siv tsis ua haujlwm.
Ntxiv nrog rau nws cov khoom siv kho tshuab zoo heev, cov ntawv nyiaj super tooj liab kuj muaj cov ntawv thov dav dav. Nws tuaj yeem siv dav hauv lub zog cia roj teeb tam sim no cov khoom siv hluav taws xob, cov roj teeb terminals, tooj liab busbars thiab lwm yam tseem ceeb, pab txhim kho lub zog ceev, kev them nqi thiab kev nyab xeeb ntawm lub zog cia. Nws yog ib qho tsim nyog hais tias cov khoom siv tau paub tas li muaj peev xwm tsim tau, tso lub hauv paus ruaj khov rau nws qhov loj - daim ntawv thov hauv lub zog cia.
Cov kws tshaj lij kev lag luam tau taw qhia tias kev yug me nyuam ntawm super tooj liab ntawv ci tsis tsuas yog muab lub tswv yim tsim tshiab rau kev npaj siab - cov ntaub ntawv tooj liab ua tau zoo, tab sis kuj tseem cuam tshuam lub zog loj rau hauv siab - kev loj hlob zoo ntawm lub ntiaj teb lub zog cia kev lag luam. Raws li cov ntaub ntawv tseem ceeb txuas mus rau sab saud thiab qis ntawm lub zog cia kev lag luam saw, kev nrov npe thiab kev siv cov ntawv nyiaj super tooj liab yuav ntxiv txhawb kev txhim kho cov khoom siv hluav taws xob thiab pab txhawb kev hloov pauv hluav taws xob thoob ntiaj teb.
