Cov kev ua tau zoo ntawm lub cev roj teeb lithium hluav taws xob yog qhov lom zem ntau rau kev tswj hwm qhov kev tsim qauv kev tsim khoom. Cov tuam txhab ua lag luam thoob ntiaj teb tau ua tiav cov txiaj ntsig kev ua tiav hauv kev tswj hwm tus tswj hwm qhov tseeb ntawm qib me me los ntawm qib me me mus rau theem nanometer. Qhov no "precision tau" muaj peev xwm tau dhau los ua lub cim tseem ceeb ntawm lub tuam txhab kev sib tw tseem ceeb.
1 Txheejogenization Txheej Txheem: Kev Ua Si Qhov Kawg Ntawm Qib Molecular Cov
Tuam Tshoj txhais "ultra -} kub siab homogenization" thev naus laus zis. Lub roj teeb muaj teeb meem tau txais 300mpa ultra- qhov kev faib tawm kom loj me me hauv lub siab luv (D90 / D10) yog tswj tsis pub dhau 1.2. Qhov no "qib molecular sib xyaw ua ke" cov neeg sawv cev ua haujlwm tsis zoo, thiab cov ntawv sib txawv ntawm cov ntawv me me, uas yog 60% qis dua cov txheej txheem ib txwm muaj. Kev sim ntawm lub zog roj teeb qhia tias cov thev naus laus zis txo cov peev xwm sib txawv ntawm 5% rau 1%, thiab txhim kho lub voj voog muaj 20%.
Lub teb chaws Yelemees "hauv online viscoor soj ntsuam" system. Thaum lub sijhawm homogenization, laser scattering txoj kev yog siv los saib xyuas lub viscosity ntawm lub sij hawm tiag tiag (nrog rau kev sib cav sib ceg ntawm cov kab sib txawv yog tsawg dua 3%. Ua ke nrog lub "ntxaib {4 4}}} download muaj peev xwm ntau lawm ntawm 5 tons / teev), nws ua kom sib xyaw ua ke thiab nce ntau lawm kev ua haujlwm los ntawm peb zaug. Tom qab thov cov thev naus laus zis hauv qee qhov chaw khaws hluav taws xob cia roj teeb hauv qab ntawm 2% mus rau 0.5%, txuag Yuan.
2 txheej thiab dov nias: geometric tswj nrog micron precision
Nyiv lub "Tsoo Slit Extrusion Txheej" txheej txheem. Lub tshuab ua lag luam ntawm ib qho kev lag luam zoo li Adinised precision ntsia hlau (sib xyaw ua ke nrog laser thuv nto li ± 1g / m ². Nws "cua kub + infrared" Composite Drying system (ntsuas kub Hauv kev tsim cov khoom siv roj teeb, cov txheej txheem no txo cov kev ua yuam kev thaum lub ntsej muag ntawm tus ncej puab tsawg dua 0.5mm / m.
Tus "adaptive roller nias" thev naus laus zis hauv Tebchaws Meskas. Cov menyuam xovxwm yog nruab nrog lub siab sensor (qhov tseeb {} Lub sijhawm sib txawv ntawm cov polarizer) Los ntawm kev siv "segmented cov menyuam nias" (lub teeb nias " Tom qab cov txheej txheem hauv qab no, lub peev xwm khaws cov ncej ntawm cov ncej ntawm ib qho xwm txheej square roj teeb nce los ntawm 8% tom qab 500 txog.
3 Los Ua Ke thiab Kev Txhaj Tshuaj: Ntim cov lav lav rau Nanoscale Vaps
Precision tswj ntawm "Laser vuam" hauv Kaus Lim Qab Teb. Nyob rau hauv lub vuam ntawm cov roj teeb ntawm sab saum toj npog npog sab saum toj (wavelength) yog siv, nrog ib qho chaw inch monstrolled ntawm 50 μ m, ib tug vuam qhov kawg sib txawv ntawm<5 μ m, and a uniform weld width (± 3 μ m). The airtightness reaches 1 × 10 ⁻⁸ Pa · m ³/s (helium mass spectrometry leak detection). This high-precision welding ensures that the battery cell does not leak during high-temperature cycling at 100 ℃, which is 10 times more reliable than traditional ultrasonic welding. After being applied in a certain power battery factory, the defect rate of battery cells decreased from 100ppm to 10ppm.
Tuam Tshoj txoj kev tsim kho hauv "Ntau Lawm Txhaj". Txais cov "hnyav + lub tshuab nqus tsev" hnyav kev txhaj tshuaj: thawj zaug ntsuas hluav taws xob ua kom muaj kev sib luag ntawm 0.5% hauv kev txhaj tshuaj ntim. Ua ke nrog "ntau theem kev tso ua ke" (lwm txoj kev ntsuas lub tshuab hluav taws xob, ua kom muaj kev txuag hluav taws xob, ua kom muaj kev txuag hluav taws xob tau nce mus rau 92%, uas yog 3% ntau dua li kev txhaj tshuaj ua kua. Ib lub zog cia roj teeb lub Hoobkas tau ua kom luv dua cov txheej txheem kev txhaj tshuaj ntawm 2 teev mus rau 1 teev los ntawm cov thev naus laus zis.
Kev tsim qauv kev tsim qauv ntawm lub cev roj teeb lithium roj teeb yog tsav tsheb rau kev lag luam los ntawm "teev nthuav dav" rau "kev sib tw" kom zoo ". Nyob rau yav tom ntej, nrog rau daim ntawv thov ntawm cov thev naus laus zis xws li cov txheej txheem sib tw ntawm nanoscale txhim kho) thiab ua tiav "qhov chaw tshiab ua kom tiav), thiab kev ntseeg tau ntawm lub roj teeb lithium.
