Khoom Taw Qhia
BCF, roj teeb copper foil rau roj teeb yog cov ntawv ci tooj liab tsim thiab tsim los ntawmCIVEN METAL tshwj xeeb rau kev lag luam roj teeb lithium. Qhov no electrolytic tooj liab ntawv ci muaj qhov zoo ntawm siab purity, tsis tshua muaj impurities, zoo nto tiav, tiaj tus nto, uniform nro, thiab yooj yim txheej. Nrog cov purity siab dua thiab zoo dua hydrophilic, electrolytic tooj liab ntawv ci rau cov roj teeb tuaj yeem ua kom cov nqi thiab tawm lub sijhawm thiab txuas ntxiv lub neej ntawm cov roj teeb. Tib lub sijhawm,CIVEN METAL tuaj yeem hlais raws li tus neeg yuav tsum tau ua kom tau raws li cov neeg siv khoom xav tau rau cov khoom siv roj teeb sib txawv.
Specifications
CIVEN muaj peev xwm muab ob-sided optical lithium tooj liab ntawv ci nyob rau hauv txawv dav ntawm 4.5 mus rau 20µm nominal thickness.
Kev ua tau zoo
Cov khoom muaj cov yam ntxwv ntawm symmetrical ob-sided qauv, hlau ntom ze rau qhov theoretical ntom ntawm tooj liab, tsis tshua muaj nto profile, siab elongation thiab tensile zog (saib daim duab 1).
Daim ntawv thov
Nws tuaj yeem siv ua anode cab kuj thiab cov khoom siv rau cov roj teeb lithium-ion.
Qhov zoo
Piv nrog rau ib leeg-sab tag nrho thiab ob-sided tag nrho lithium tooj liab ntawv ci, nws qhov chaw sib cuag tau nce exponentially thaum nws tau sib koom nrog cov khoom siv tsis zoo electrode, uas tuaj yeem txo qhov kev sib cuag ntawm cov khoom tsis zoo electrode thiab cov khoom tsis zoo electrode thiab txhim kho cov khoom siv hluav taws xob. symmetry ntawm qhov tsis zoo electrode daim ntawv qauv ntawm lithium-ion roj teeb. Meanwhile, ob-sided lub teeb lithium tooj liab ntawv ci muaj qhov ua tau zoo rau qhov txias thiab kub nthuav dav, thiab cov ntawv tsis zoo electrode tsis yooj yim tawg thaum lub sijhawm them thiab tawm ntawm cov roj teeb, uas tuaj yeem ua rau lub neej ntev ntawm lub roj teeb.
