Composite copper foil factories yog secretive heev txog cov cim tseem ceeb thiab kev txiav txim raws li txoj cai ntawm lawv cov khoom, ua rau lub lag luam theem nrab muaj kev kub ntxhov los ntawm ib ntus vim "cov ntawv me me". Nyob rau xyoo 2023 Gaogong Lithium Battery Conference, Dr. Sun Yaoming, tus thawj coj ntawm Jinmei New Materials Application Center, kwv yees tias tus nqi ntawm cov ntaub ntawv tooj liab sib xyaw yuav zoo ib yam li cov ntawv ci tooj liab electrolytic hauv lub quarter thib plaub ntawm xyoo tom ntej.
Tsis tas li ntawd, raws li kev sib txuas lus offline ntawm Cailian News reporters thiab composite copper foil factories, upstream khoom factories thiab lwm yam kev lag luam saw cov neeg ua hauj lwm, feem ntau ntawm cov technical routes ntawm composite tooj liab foil factories tau hloov los ntawm PET mus rau los yog ib txhij tsim PP txoj kev. Txawm li cas los xij, raws li ib tus neeg muaj feem cuam tshuam nrog cov ntawv ci tooj liab, qhov nyuaj ntawm txoj kev PP yog li ntawm 2-3 zaug nyuaj dua li ntawm PET.
Xyoo tom ntej Q4 tus nqi yuav nyob twj ywm zoo ib yam li cov ntawv ci tooj liab
Jinmei Cov Khoom Tshiab yog cov chaw tsim khoom tseem ceeb ntawm cov khoom siv tam sim no hauv Suav teb. Nws tau ntxim nyiam ntawm kev lag luam peev vim nws txoj kev loj hlob sai hauv PP txoj kev thiab nws txoj kev sib raug zoo nrog CATL. Dr. Sun Yaoming, tus thawj coj ntawm nws qhov chaw thov, tau qhia tawm ntawm 2023 Gaogong Lithium Roj Teeb Lub Rooj Sib Tham Txhua Xyoo hais tias cov khoom tsim tawm thiab cov txheej txheem ntau lawm feem ntau muab faib ua ABCD qauv.
Thawj theem yog lub tswv yim tsim theem, uas feem ntau txiav txim siab seb yam khoom twg xav tau thiab txhim kho thiab txheeb xyuas seb cov txheej txheem khoom puas ua tau. Cov txheej txheem no feem ntau tsim cov qauv B, thiab cov qauv AB yog cov khoom tsim khoom, uas yog, theem 0-1.
Nws tau hais ntxiv tias nyob rau theem kev txhim kho, lub tuam txhab yuav muaj cov khoom lag luam batch, cov txheej txheem ruaj khov, thiab thaum kawg tsim cov qauv C, uas yog cov khoom theem. Hauv kev nthuav dav ntxiv tom ntej, muaj cov khoom lag luam ruaj khov uas tau txheeb xyuas los ntawm cov neeg siv khoom, suav nrog cov txheej txheem tsim khoom thiab khoom siv. Lub sijhawm no, lub tuam txhab yuav them nyiaj ntau dua rau kev lag luam theem ntawm kev sib xws, muaj peev xwm ntau lawm, kev ua tau zoo thiab tus nqi. Lub sijhawm no, D Sample. Los ntawm tus qauv C mus rau tus qauv D yog txheej txheem ntawm 1-100.
Raws li Dr. Sun Yaoming, lub tuam txhab tau nyob rau hauv A-hom theem hauv 2015, B-hom theem hauv 2018, C-hom hauv 2022, thiab D-hom theem hauv 2023 thaum lub tuam txhab nthuav tawm kev tsim tawm. Pib txij xyoo 2020, cov txheej txheem tsim qauv ntawm MC (cov ntawv ci tooj liab sib xyaw) tau raug kho, los ntawm cov qauv hloov mus rau theem khoom, thiab tau nce zuj zus tuaj.
Raws li cov ntaub ntawv pej xeem, Jinmei Cov Khoom Tshiab tam sim no ua qauv qhia hauv Qijiang, Chongqing tuaj yeem ua tiav txhua xyoo muaj peev xwm ntawm kwv yees li 100 lab square meters. Nyob rau lub Tsib Hlis xyoo no, Jinmei Cov Khoom Siv Tshiab 'cov khoom siv ntau yam tam sim no sib xyaw ua ke nthuav tawm qhov project tau raug kos npe thiab nyob hauv Nanxi District, Yibin City, Sichuan Province. Lub hauv paus muaj tag nrho cov peev ntawm 5.5 billion yuan thiab npaj tsim muaj peev xwm ntawm 1.2 billion square metres, uas yuav tau ua nyob rau hauv theem.
Hais txog tus nqi, Dr. Sun Yaoming tau hais tias kev lag luam yog kev txhawj xeeb tshaj plaws txog tus nqi. Lub tuam txhab tau txais cov txheej txheem kev siv nyiaj zoo tshaj plaws. Cov theem tom ntej yuav tsum yog qhov pib zoo ib yam li cov ntaub ntawv electrolytic tooj liab, thiab cov theem tom ntej yuav tsum yog nyob rau lub quarter thib plaub ntawm xyoo tom ntej.
Txog tam sim no, cov neeg sau xov xwm los ntawm Cailian Xov Xwm sib tham offline nrog cov neeg muaj feem cuam tshuam los ntawm ob lub chaw tsim khoom siv tooj liab thiab tau kawm tias tus nqi muag khoom ntawm cov ntawv ci tooj liab yog li 10% mus rau 20% siab dua li cov roj teeb lithium tooj liab. Ib tug ntawm cov neeg sab hauv kev lag luam tau hais tias cov nqi yuav poob qis rau yav tom ntej. Tam sim no, lub tuam txhab feem ntau yog xyuas kom muaj nuj nqis, thiab lub tuam txhab tseem xav tau kev txhim kho txuas ntxiv, tsis tau them nyiaj ntau rau cov txiaj ntsig.
Lwm cov neeg sab hauv kev lag luam tau hais rau cov neeg sau xov xwm los ntawm Lub Tsev Haujlwm Saib Xyuas Nyiaj Txiag tias thaum cov txiaj ntsig ntawm cov ntaub ntawv tooj liab sib xyaw nce mus txog ntau dua 80%, tus nqi yuav zoo ib yam li cov roj teeb lithium tooj liab. Tom qab ncav cuag ntau dua 90%, tus nqi yuav qis dua li cov roj teeb lithium tooj liab ntawv ci.
Dr. Sun Yaoming tau tshaj tawm cov ntaub ntawv ua tau zoo tshaj plaws, hais tias lub tuam txhab cov txheej txheem MC cov txiaj ntsig tam sim no ntau dua 85%, thiab qhov yob ntev tau nce mus rau 10, 000 meters. Raws li ib tus neeg koom nrog ntawm cov khoom sib xyaw tooj liab ntawv ci, ib tus neeg sau xov xwm los ntawm Financial Associated Press tau hais tias qhov teeb meem tam sim no ntawm kev sib xyaw tooj liab ntawv ci sawb tawg yog qhov pib daig ntawm 1000-2000 meters.
Dr. Sun Yaoming kuj tau qhia txog qhov xav tau ntawm cov ntawv txhuas sib xyaw (MA). Nws hais tias tam sim no cov khoom tsis txaus. Nyob rau theem tom ntej, lub tuam txhab yuav txuas ntxiv nthuav ntau lawm thiab nce cov khoom xa tuaj. Nyob rau theem tom ntej, kev xa khoom yuav nce 50%. Tus nqi yuav raug txo los ntawm 50%.
Ntawm qhov tod tes, cov neeg nyob hauv cov saw hlau cuam tshuam kev lag luam kuj tau hais txog kev txhawj xeeb. Lawv ntseeg tias cov khoom sib xyaw tam sim no tseem muaj teeb meem, thiab sab hauv lawv tab tom xav txog seb lawv puas yog cov khoom hloov pauv, vim tias tom qab cov roj teeb mus txog cov khoom lag luam ib nrab / tag nrho lub xeev, cov teeb meem kev nyab xeeb yuav raug daws. Txawm li cas los xij, yog tias siv cov khoom siv sib xyaw ua ke tam sim no, ob qho tib si lub Hoobkas thiab cov khoom siv roj teeb yuav xav tau kev sib koom ua ke los txiav txim seb qhov kev siv peev nyiaj puas yuav raug nqi.
Txoj kev PP tej zaum yuav muaj sab tes xis
Cov khoom sib xyaw tam sim no yog ib hom tshiab ntawm cov khoom siv tam sim no nrog cov qauv sandwich ntawm "hlau conductive txheej-polymer khoom txhawb txheej-hlau conductive txheej". Raws li txoj cai, cov ntawv txhuas sib xyaw tooj liab muaj qhov zoo ntawm kev nyab xeeb siab, tus nqi qis thiab lub zog siab ntom ntom piv rau cov ntawv ci tooj liab. Tam sim no, txoj hauv kev tseem ceeb yog PP puag zaj duab xis thiab PET puag zaj duab xis.
Yu Can, tus kws tshuaj xyuas tooj liab, sawb thiab ntawv ci ntawm Shanghai Ganglian Copper Division, tau hais rau tus neeg sau xov xwm los ntawm Lub Koom Haum Xov Xwm thaum ntxov tias PET tooj liab ntawv ci muaj teeb meem dhia dhia, PP zaj duab xis muaj qhov qis melting point, tsis zoo tensile. lub zog, thiab tam sim no tsis muaj lub hom phiaj kev txhim kho. PP copper foil Cov txheej txheem fwj yog siab heev, feem ntau yog pom hauv cov teeb meem adhesion ntawm PP thiab tooj liab txheej, tensile zog thiab kub tsis kam.
Ib tus neeg sau xov xwm los ntawm Cailian Xov Xwm tau pom tias cov tsev lag luam A-kev sib xyaw tooj liab ntawv ci xws li Baoming Technology, Yinglian Co., Ltd. thiab Putilai feem ntau tsom rau txoj kev PET hauv kev tshawb fawb thiab kev tsim cov ntawv ci tooj liab sib xyaw ua ke thaum ntxov, tab sis tom qab ntawd. lawv txhua tus tig mus rau lossis ib txhij tsim PP. txoj kev.
Ib tug neeg los ntawm PP txoj kev sib xyaw tooj liab ntawv ci Hoobkas tau hais rau tus neeg sau xov xwm los ntawm Financial Associated Press tias qhov teeb meem dhia dej ntawm PET yog qhov hnyav heev. Qhov tseeb tsis muaj dab tsi los tham txog ntawm ntau yam kev ua tau zoo ntawm PET thiab PP, vim tias qhov tseem ceeb tshaj plaws rau cov khoom sib xyaw tam sim no yog los daws qhov teeb meem ntawm kev nyab xeeb. , tab sis tom qab siv PET cov khoom siv tam sim no tau ntau xyoo, qhov kev pheej hmoo tseem ntau dua thiab nws pom tseeb tias siv tsis tau.
Nws piav qhia tias cov phooj ywg xaiv txoj kev PET thaum ntxov vim tias PET yooj yim heev rau kev ua. Tsis tsuas yog nws muaj zog adhesion, tab sis nws kuj zoo dua PP nyob rau hauv cov nqe lus ntawm kub kub kuj thiab tensile zog. Qhov no kuj yog vim li cas cov tuam txhab tshiab nyiam PET vim tias nws yooj yim siv thiab siv tau yooj yim. Haum rau cov neeg tuaj tshiab los pib.
Tus neeg hais saum toj no kuj tau hais tias kev hloov ntawm PET rau PP tsis yog qhov yooj yim. Cov txheej txheem PP nyuaj dua li PET, txog 2-3 zaug. Raws li tus neeg sau xov xwm los ntawm Cailian Xov Xwm, lub Hoobkas sib xyaw tooj liab ntawv ci uas tus neeg no ua haujlwm tau muaj ob qhov kev teeb tsa ntawm PET thiab PP thaum ntxov, tab sis tau muab tso rau ntawm txoj kev PET.
Kev lag luam ntseeg hais tias nws yog ib qho teeb meem ntawm cyclic diving. Ib tus neeg muaj feem cuam tshuam los ntawm cov khoom siv tooj liab sib xyaw ua ke tau hais rau cov neeg sau xov xwm los ntawm Kev Sib Tham Nyiaj Txiag tias ntau tus neeg siv khoom tau nug txog PET cov kab ntau lawm, tab sis tam sim no yeej tsis muaj cov neeg siv khoom, thiab lawv txhua tus tau tig mus rau txoj kev PP.
Thaum lub rooj sib tham, tus neeg sau xov xwm los ntawm Cailian Xov Xwm tau sib tham nrog ib tus neeg uas tau nthuav tawm lub rooj muag khoom PET cov tooj liab tooj liab. Nws tau lees paub tias PET muaj teeb meem dhia dej, tab sis ntseeg tias PET cov ntawv ci tooj liab tseem muaj qhov zoo ntawm cov neeg siv khoom thiab kev lag luam tsheb ob lub log. Nyob rau tib lub sijhawm, nws kuj tau hais tias lub tuam txhab yuav muaj cov khoom PP tshiab ntawm kev ua lag luam yav tom ntej.
Txawm li cas los xij, Wang Rongfu, tus thawj coj ntawm kev sib xyaw tooj liab ntawv ci Hoobkas Hanxi Cov Khoom Siv Tshiab, "platformed" txoj kev PET ntawm 2023 Senior Engineer Lithium Roj teeb Lub Rooj Sib Tham Txhua Xyoo. Hais txog qhov xwm txheej uas cov ntaub ntawv PET tau tsau rau hauv cov cua sov electrolytes thiab dhia mus rau hauv kev ntsuas kev voj voog, Wang Rongfu ntseeg tias "nws tuaj yeem ua rau electrolyte resistant los ntawm kev hloov kho, thiab tsawg kawg ntawm cov voj voog tuaj yeem nce ntxiv."
Wang Rongfu tseem ntseeg tias tam sim no, peb tseem yuav tsum tau txav mus rau PET hloov kho, vim tias cov ntaub ntawv PP nyuaj rau yuav; thib ob, cov txheej txheem yog qhov nyuaj. Nws tau hais tias txawm tias kev txhim kho PP daws qhov teeb meem uas tsis tsom rau, tus nqi txo qis.
