Cov roj teeb lithium tau muab cais raws li daim ntawv ntim khoom, thiab feem ntau muab faib ua peb hom: roj teeb cylindrical, roj teeb prismatic, thiab lub hnab roj teeb.
Lub roj teeb cylindrical tau tsim los ntawm Sony thiab tau siv rau cov neeg siv khoom siv roj teeb thaum ntxov. Tesla nrov rau lawv nyob rau hauv lub tshav pob ntawm hluav taws xob tsheb. Xyoo 1991, Sony tau tsim lub ntiaj teb thawj lub lag luam lithium roj teeb - 18650 cylindrical roj teeb, pib cov txheej txheem lag luam ntawm lithium roj teeb. Thaum lub Cuaj Hlis 2020, Tesla tau tso tawm 4680 lub roj teeb loj cylindrical, uas muaj lub peev xwm ntawm tes uas yog tsib zaug siab dua li ntawm 21700 roj teeb, thiab tus nqi tau ua kom zoo dua ntxiv. Cov roj teeb cylindrical tau siv dav hauv kev lag luam tsheb hluav taws xob txawv teb chaws: tshwj tsis yog Tesla, ntau lub tuam txhab tsheb tau nruab nrog cov roj teeb cylindrical tam sim no.
Cylindrical roj teeb shells thiab zoo electrode caps feem ntau yog ua los ntawm npib tsib xee-hlau alloy los yog txhuas alloy cov ntaub ntawv nrog ib tug tuab ntawm txog 0.3 hli. Daim ntawv thov ntawm laser vuam nyob rau hauv cylindrical roj teeb feem ntau muaj xws li tiv thaiv valve hau vuam & busbar zoo & tsis zoo electrode vuam, Busbar-PACK hauv qab phaj vuam, thiab roj teeb sab hauv tab vuam.
| Vuam Parts | Khoom siv |
| Kev tiv thaiv valve hau vuam & Busbar zoo & tsis zoo electrode vuam | Nickel & Aluminium - Nickel-Fe & Txhuas |
| Busbar-PACK puag phaj vuam | Nickel & Aluminium - Txhuas & Stainless hlau |
| Roj teeb sab hauv tab welding | Nickel & Copper Nickel Composite Sawb - Nickel Hlau & Txhuas |
1, Lub tuam txhab ua raws li R & D thiab kev tsim khoom ntawm cov khoom siv kho qhov muag thiab hauv kev ua haujlwm ntawm cov khoom siv hluav taws xob hauv tsheb, peb pab pawg muaj kev paub dhau los hauv kev siv tshuab scanner vuam taub hau thiab tswj;
2 、 Cov khoom tseem ceeb yog txhua tus ntawm nws tus kheej tsim thiab tsim khoom, nrog lub sijhawm xa khoom luv thiab qis dua cov khoom lag luam zoo sib xws; lub tuam txhab pib hauv optics thiab tuaj yeem kho kho qhov muag scanning taub hau rau cov neeg siv khoom; nws tuaj yeem tsim lub taub hau galvo rau ntau yam kev xav tau sensor;
3 、 Cov lus teb sai tom qab muag; muab tag nrho cov kev daws teeb meem vuam thiab kev txhawb nqa ntawm qhov chaw;
4, Lub tuam txhab muaj ib pab neeg nrog kev nplua nuj nyob rau hauv pem hauv ntej-kab txoj kev txhim kho, khoom debugging thiab daws teeb meem nyob rau hauv lub roj teeb teb; nws tuaj yeem muab cov txheej txheem kev tshawb fawb thiab kev tsim kho, ua qauv pov thawj thiab kev pabcuam OEM.
