mabatire a ithium-ion ali ndi ntchito zosiyanasiyana. Malinga ndi kagawidwe ka madera ogwiritsira ntchito, imatha kugawidwa mu batri yosungiramo mphamvu, batire yamagetsi ndi batire yamagetsi ogula.
- Battery yosungirako mphamvu imakwirira kusungirako mphamvu zoyankhulirana, kusungirako mphamvu zamagetsi, machitidwe ogawa mphamvu, ndi zina zotero;
- Batire yamagetsi imagwiritsidwa ntchito makamaka m'munda wamagetsi, kutumizira msika kuphatikiza magalimoto amagetsi atsopano, ma forklift amagetsi, etc.;
- Battery yamagetsi ogula imakhudza gawo la ogula ndi mafakitale, kuphatikiza metering yanzeru, chitetezo chanzeru, mayendedwe anzeru, intaneti ya Zinthu, ndi zina zambiri.
Lifiyamu-ion batire ndi dongosolo zovuta, makamaka wopangidwa ndi anode, cathode, electrolyte, olekanitsa, wokhometsa panopa, binder, conductive wothandizila ndi zina zotero, kuphatikizapo zochita kuphatikizapo electrochemical anachita anode ndi cathode, lifiyamu ion conduction ndi conduction pakompyuta, komanso kutentha kufalitsa.
Njira yopangira mabatire a lithiamu ndi yayitali, ndipo njira zopitilira 50 zimakhudzidwa.
Mabatire a lithiamu amatha kugawidwa m'mabatire a cylindrical, mabatire a aluminiyamu a square, mabatire a thumba ndi mabatire atsamba malinga ndi mawonekedwe. Pali kusiyana mu ndondomeko yawo yopanga, koma chonse cha lifiyamu batire kupanga ndondomeko akhoza kugawidwa mu ndondomeko kutsogolo-mapeto (electrode kupanga), ndondomeko yapakati-gawo (maselo kaphatikizidwe), ndi ndondomeko kumbuyo-mapeto (mapangidwe ndi ma CD).
Njira yakutsogolo yakupanga batire ya lithiamu idzafotokozedwa m'nkhaniyi.
Cholinga chopangira njira yakutsogolo ndikumaliza kupanga ma elekitirodi (anode ndi cathode). Njira yake yayikulu ndi: slurrying/kusakaniza, kupaka, calendering, slitting, ndi kufa kudula.
Kusakaniza / Kusakaniza
Slurrying/kusakaniza ndi kusakaniza olimba batire zipangizo anode ndi cathode wogawana ndiyeno kuwonjezera zosungunulira kuti slurry. Kusanganikirana kwa slurry ndiko poyambira kumapeto kwa mzere, ndipo ndiye chiyambi cha kumaliza kwa zokutira, kalendala ndi njira zina.
Lithium batire slurry imagawidwa mu zabwino electrode slurry ndi negative electrode slurry. Ikani yogwira zinthu, conductive mpweya, thickener, binder, zowonjezera, zosungunulira, etc. mu chosakanizira mu gawo, Posakaniza, kupeza yunifolomu kubalalitsidwa kwa olimba-zamadzimadzi kuyimitsidwa slurry kwa ❖ kuyanika.
Kusakaniza kwapamwamba kwambiri ndiko maziko a kutsirizitsa kwapamwamba kwa ndondomeko yotsatira, yomwe idzakhudza mwachindunji kapena mosadziwika bwino ntchito ya chitetezo ndi electrochemical ntchito ya batri.
Kupaka
Kuphimba ndi ndondomeko ❖ kuyanika zabwino yogwira zakuthupi ndi zoipa yogwira zinthu pa aluminiyamu ndi mkuwa zojambula motero, ndi kaphatikizidwe ndi wothandizira conductive ndi binder kupanga elekitirodi pepala. The zosungunulira ndiye kuchotsedwa ndi kuyanika mu uvuni kuti olimba zinthu ndi bonded ku gawo lapansi kupanga zabwino ndi zoipa elekitirodi pepala koyilo.
Kupaka cathode ndi anode
Zida za Cathode: Pali mitundu itatu ya zipangizo: kapangidwe ka laminated, kapangidwe ka spinel ndi kapangidwe ka olivine, zomwe zimagwirizana ndi zipangizo za ternary (ndi lithiamu cobaltate), lithiamu manganate (LiMn2O4) ndi lithiamu iron phosphate (LiFePO4) motsatira.
Zipangizo za anode: Pakali pano, zinthu za anode zomwe zimagwiritsidwa ntchito mu batri ya lithiamu-ion makamaka zimaphatikizapo zinthu za carbon ndi zinthu zopanda mpweya. Pakati pawo, zida za kaboni zikuphatikizapo graphite anode, yomwe imagwiritsidwa ntchito kwambiri pakalipano, ndi carbon anode yosokonezeka, carbon carbon, carbon soft, etc.; zinthu zopanda mpweya monga silicon-based anode, lithiamu titanate (LTO) ndi zina zotero.
Monga ulalo wapakatikati wa njira yakutsogolo, kuphatikizika kwa njira zokutira kumakhudza kwambiri kusasinthika, chitetezo ndi moyo wa batri yomalizidwa.
Calendar
The elekitirodi TACHIMATA ndi zina tikaumbike ndi wodzigudubuza, kuti yogwira mankhwala ndi wokhometsa ali pafupi kukhudzana wina ndi mzake, kuchepetsa kayendedwe mtunda wa ma elekitironi, kutsitsa makulidwe a elekitirodi, kuwonjezera Mumakonda mphamvu. Nthawi yomweyo, imatha kutsitsa kukana kwamkati kwa batri, kukulitsa madulidwe, ndikukweza kuchuluka kwa magwiritsidwe ntchito a batri kuti awonjezere mphamvu ya batri.
The flatness wa elekitirodi pambuyo calendering ndondomeko mwachindunji zimakhudza zotsatira slitting ndondomeko wotsatira. Kufanana kwa chinthu chogwira ntchito cha elekitirodi kudzakhudzanso magwiridwe antchito a cell.
Kudula
Slitting ndi kudula kosalekeza kwa koyilo ya elekitirodi m'magawo opapatiza a m'lifupi mwake. Mu slitting, electrode ikukumana ndi kumeta ubweya wa ubweya ndikusweka, Mphepete mwa nthiti pambuyo podula (palibe burr ndi kusinthasintha) ndiye chinsinsi chowunika momwe ntchitoyo ikuyendera.
Njira yopangira ma elekitirodi imaphatikizapo kuwotcherera ma elekitirodi tabu, kugwiritsa ntchito pepala lomatira zoteteza, kukulunga tabu ya elekitirodi ndikugwiritsa ntchito laser kudula tabu ya elekitirodi panjira yokhotakhota. Kudula-kufa ndikudinda ndikusintha ma elekitirodi ophimbidwa kuti azitha kuchita.
Chifukwa cha zofunikira kwambiri pachitetezo chachitetezo cha batri la lithiamu-ion, kulondola, kukhazikika komanso kukhazikika kwa zida zimafunidwa kwambiri pakupanga batire ya lithiamu.
Monga mtsogoleri wa zida zoyezera ma electrode a lithiamu, Dacheng Precision yakhazikitsa mndandanda wazinthu zoyezera ma electrode kutsogolo-kumapeto kwa kupanga batri ya lithiamu, monga X / β-ray areal density gauge, CDM makulidwe ndi areal density gauge, laser makulidwe gauge ndi zina zotero.
- Super X-ray areal density gauge
Imasinthasintha ndi muyeso wa zokutira zopitilira 1600 mm, imathandizira kusanthula kothamanga kwambiri, ndipo imazindikira zatsatanetsatane monga madera owonda, zokopa, ndi m'mphepete mwa ceramic. Zingathandize ndi zokutira zotsekedwa.
- X/β-ray areal density gauge
Imagwiritsidwa ntchito munjira yopaka ma electrode ya batri ndi njira yopaka yolekanitsa ya ceramic poyesa pa intaneti pakuchulukira kwa chinthu chomwe chayezedwa.
- Makulidwe a CDM & Areal Density Gauge
Itha kugwiritsidwa ntchito pakupanga ❖ kuyanika: kuzindikira kwatsatanetsatane kwa maelekitirodi pa intaneti, monga zokutira zomwe zaphonya, kusowa kwa zinthu, zokopa, makulidwe a madera owonda, kuzindikira makulidwe a AT9, etc.;
- Multi-frame synchronous tracking measurement system
Amagwiritsidwa ntchito popaka ma cathode ndi anode ya mabatire a lithiamu. Imagwiritsa ntchito mafelemu ojambulira angapo kuti ipange miyeso yotsatizana yotsatizana pa maelekitirodi. Dongosolo loyezera lotsata mafelemu asanu limatha kuyang'ana filimu yonyowa, kuchuluka kwa zokutira, ndi electrode.
- Laser makulidwe gauge
Amagwiritsidwa ntchito kuti azindikire ma elekitirodi mu njira yokutira kapena calendering ya mabatire a lithiamu.
- Makulidwe a Offline & dimension gauge
Amagwiritsidwa ntchito kuti azindikire makulidwe ndi kukula kwa maelekitirodi mu njira yokutira kapena calendering ya mabatire a lithiamu, zomwe zimapangitsa kuti magwiridwe antchito azikhala osasinthasintha.
