Muaj ob qho laj thawj rau kev siv cov ntawv txhuas txhuas ua cov cathode tam sim no ntawm cov roj teeb lithium-ion: Ua ntej, aluminium nto muaj cov txheej txheem oxide tuab thiab muaj cov tshuaj muaj zog, uas tuaj yeem tiv thaiv cov khoom tam sim no los ntawm oxidized thiab corroded los ntawm electrolyte, thiab tib lub sijhawm, lithium insertion cov tshuaj tiv thaiv yuav tsis tshwm sim. Thib ob, siv cov ntawv txhuas txhuas ua cov khoom siv tam sim no tuaj yeem txo qhov kev sib cuag ntawm cov khoom siv hluav taws xob zoo / tsis zoo thiab cov khoom siv tam sim no, txhim kho qhov adhesion ntawm ob, thiab txhim kho kev ua haujlwm ntawm lub tsheb fais fab.
Qhov zoo thiab tus nqi ntawm cov roj teeb aluminium ntawv ci yog tsawg, thiab nws yog ib qho zais cia ntawm cov khoom ntawm lithium roj teeb. Qhov hnyav ntawm roj teeb aluminium ntawv nyiaj rau 5%, ua raws li cov khoom siv hluav taws xob zoo, cov khoom tsis zoo electrode, electrolytes, thiab tooj liab ntawv ci; nws cov nqi kwv yees li 3% ntawm tag nrho cov nqi ntawm lithium roj teeb, ua raws li lithium roj teeb zoo electrode cov ntaub ntawv, cov khoom sib cais, cov ntaub ntawv tsis zoo electrode, cov ntawv ci tooj liab, thiab electrolyte, qis qis thiab tus nqi feem ntau ua rau tib neeg tsis quav ntsej nws qhov tseem ceeb.
