Cov Roj Teeb Lithium-Ion Hauv Hnab: Kev Txheeb Xyuas Tag Nrho

Cov tabs yog cov khoom tseem ceeb hauv cov roj teeb lithium-ion, ua haujlwm ua cov choj conductive ntawm lub roj teeb sab hauv electrodes thiab cov circuits sab nraud. Ntau tshaj li cov connectors yooj yim, lawv ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj kev nyab xeeb ntawm lub roj teeb, kev ua haujlwm sealing, thiab kev ua haujlwm zoo tag nrho. Tsab xov xwm no tshawb nrhiav cov hom, cov ntaub ntawv, cov yam ntxwv kev ua tau zoo, thiab kev siv ntawm cov khoom tseem ceeb no, muab cov kev nkag siab zoo rau cov chaw tsim khoom thiab cov engineers.

Cov Tabs Roj Teeb Yog Dab Tsi?

Hauv lawv lub plawv, cov ntawv nplaum roj teeb yog cov qauv sib xyaw ua ke uas muaj ob ntu tseem ceeb: ib daim hlau thiab ib daim yas (cov ntawv nplaum). Daim hlau ua haujlwm ua tus neeg xa hluav taws xob, xa cov hluav taws xob ntawm cov electrodes zoo / tsis zoo ntawm lub roj teeb thiab cov khoom siv sab nraud. Lub sijhawm no, daim yas muab lub foob kom tiv thaiv cov electrolyte xau thiab rwb thaiv cov hlau ntawm cov hluav taws xob luv luv.

1. Cov tabs zoofeem ntau yog ua los ntawm txhuas (Al) vim nws cov hluav taws xob zoo heev thiab tiv taus corrosion.
2. Cov tabs tsis zoosiv cov npib tsib xee (Ni) lossis tooj liab uas muaj npib tsib xee (Ni-Cu). Cov npib tsib xee feem ntau siv rau hauv cov khoom siv digital me me, thaum cov npib tsib xee uas muaj npib tsib xee—uas muaj nqis rau lawv lub peev xwm nqa hluav taws xob siab—yog cov uas nyiam siv rau cov roj teeb fais fab thiab cov ntawv thov uas siv hluav taws xob ntau.

Kev faib tawm ntawm Tabs

Cov tabs raug cais raws li lawv cov khoom siv, hom nplaum, thiab ntim khoom, txhua qhov haum rau cov xwm txheej siv tshwj xeeb:

1. Los ntawm Cov Khoom Siv Hlau

1. Cov ntawv txhuas (Al)Feem ntau siv rau cov electrodes zoo. Lawv kuj tseem siv tau ua cov electrodes tsis zoo hauv cov roj teeb uas muaj lithium titanate anodes.
2. Cov ntawv cim Nickel (Ni)Tsuas yog siv rau cov electrodes tsis zoo hauv cov khoom siv hluav taws xob tsawg xws li smartphones, ntsiav tshuaj, thiab cov txhab nyiaj fais fab.
3. Nickel-plated tooj liab (Ni-Cu) tabsTsim los rau cov electrodes tsis zoo hauv cov roj teeb fais fab (piv txwv li, tsheb fais fab) thiab cov roj teeb siab, sib txuas cov tooj liab txoj kev ua hluav taws xob nrog nickel txoj kev tiv thaiv xeb.

2. Los ntawm Tab Adhesive Hom

Cov lag luam hauv tebchaws faib cov nplaum raws li xim, qhia txog qhov sib txawv ntawm qhov zoo thiab kev siv:

1. Cov ntawv nplaum dubSiv rau hauv cov roj teeb digital qis-rau-nruab nrab. Lawv cov qauv (lub plawv zaj duab xis PEN nrog cov txheej PP hloov kho) muaj kev pheej hmoo ntawm kev tawg raws sijhawm.
2. Cov ntawv nplaum dajFeem ntau siv rau cov roj teeb fais fab nruab nrab. Txawm hais tias yooj yim dua rau kev kaw, lawv cov tub ntxhais tsis-woven tuaj yeem nqus cov dej noo, ua rau lub roj teeb o.
3. Cov ntawv nplaum dawb: Zoo siv rau cov khoom siv digital zoo, cov roj teeb fais fab, thiab cov roj teeb kim. Muaj nyob rau hauv ib txheej, peb txheej, lossis tsib txheej, cov nplaum dawb peb txheej (nrog PP cores) muab kev sib khi zoo dua thiab tsis muaj kev pheej hmoo ntawm kev tawg.
4. Cov ntawv dov: Cov kab txuas ntxiv mus ua yob, zoo tagnrho rau cov kab ntau lawm tsis siv neeg.
5. Cov ntawv tabs: Cov ntawv nyias nyias uas muab tso rau ntawm cov ntawv yas, tsim rau kev ua tes lossis cov txheej txheem semi-automated.

3. Los ntawm Kev Ntim Khoom

1. Cov ntawv dov: Cov kab txuas ntxiv mus ua yob, zoo tagnrho rau cov kab ntau lawm tsis siv neeg.
2. Cov ntawv tabs: Cov ntawv nyias nyias uas muab tso rau ntawm cov ntawv yas, tsim rau kev ua tes lossis cov txheej txheem semi-automated.

Cov Khoom Siv Tseem Ceeb thiab Kev Ua Tau Zoo

Kev ua tau zoo ntawm cov tabs nyob ntawm seb lawv cov khoom siv li cas:

1. Cov hlau strips: Txhuas (AL1050 alloy) thiab tooj liab (TU1 oxygen-free copper) yog cov khoom siv uas nyiam siv rau lawv txoj kev ua hluav taws xob, kev yoog tau yooj yim, thiab kev tiv taus xeb. Kev plating nickel rau ntawm cov hlau tooj liab tiv thaiv kev oxidation thiab txhim kho kev sib txuas.
2. Cov nplaum rau ntawm daim ntawv nplaumFeem ntau cov nplaum yog xa los ntawm Nyiv Pooj teb, vim tias cov khoom siv PP hauv tebchaws nyuaj rau ua kom tau raws li qhov yuav tsum tau ua kom nruj. Cov nplaum zoo (piv txwv li, cov nplaum dawb peb txheej) sib npaug qhov tiv taus cua sov (qhov chaw yaj ~ 147 ° C) thiab kev ywj pheej, ua kom ntseeg tau tias kev sib khi zoo nrog cov yas txhuas.

Kev Tsim Khoom thiab Kev Tswj Xyuas Zoo

Kev tsim cov ntawv nplaum ua haujlwm tau zoo yuav tsum muaj kev ua tib zoo:

1. Cov txheej txheem platingCov ntawv tooj liab uas muaj nickel plated siv electroplating (1.8±0.3μm tuab) lossis electroless plating (1.0±0.3μm tuab) kom ntseeg tau tias muaj kev npog sib npaug.
2. Kev txiav ntugCov hlau uas tuab dua 0.2 hli yuav tsum tau txiav ntug kom tsis txhob muaj teeb meem rwb thaiv tsev thiab kev pheej hmoo ntawm kev xau.
3. Kev kuaj xyuas nruj:
   1. Kev ntsuam xyuas electrolyte immersionCov ntawv nplaum yuav tsum tswj tau lub zog foob > 15N/15mm tom qab 24 teev ntawm 85°C.
   2. Kev ntsuam xyuas khoovCov tabs yuav tsum tiv taus 5-7 qhov khoov (nyob ntawm seb tuab npaum li cas) kom ntseeg tau tias ruaj khov hauv qhov chaw co (piv txwv li, tsheb fais fab).

Cov Kev Sib Txuas Tab

Kev txuas cov tabs rau cov circuits sab nraud muaj ntau txoj kev:

1. Kev sib txuas ua ke: Kev tho thiab ntsia hlau muab cov kev sib txuas pheej yig, muaj zog tab sis yuav tsum tau tswj qhov tuab kom zoo.
2. Kev siv vuam: Cov khoom siv M51 uas kub tsawg ua haujlwm rau cov hlau sib txawv (piv txwv li, tooj liab thiab txhuas) tab sis kim heev.
3. Kev vuam ultrasonicTxoj kev zoo tshaj plaws rau cov roj teeb fais fab, siv cov kev co siab los txuas cov ntawv ci nyias nyias (0.01mm) yam tsis muaj cua sov ntau dhau.

Xaus lus

Cov ntawv nplaum tej zaum yuav me me, tab sis lawv tus qauv tsim thiab qhov zoo cuam tshuam ncaj qha rau kev ua haujlwm ntawm lub roj teeb hauv hnab. Thaum qhov kev thov rau cov roj teeb muaj kev nyab xeeb dua, ua haujlwm tau zoo dua hauv cov tsheb fais fab thiab kev khaws cia hluav taws xob, kev nce qib hauv cov ntaub ntawv ntawv nplaum (piv txwv li, cov nplaum ntau txheej) thiab kev tsim khoom (piv txwv li, kev plating meej) yuav tseem ceeb heev. Kev nkag siab txog cov yam ntxwv ntawm ntawv nplaum yog qhov tseem ceeb rau kev ua kom lub roj teeb muaj kev ntseeg siab thiab siv tau ntev hauv ntau yam kev siv.
