Raws li cov khoom siv carbon nrog cov khoom siv hluav taws xob siab thiab cov cheeb tsam tshwj xeeb, cov pa roj carbon nanotubes tuaj yeem txhim kho cov khoom siv thiab kev faib tawm ntawm cov khoom siv, txhim kho cov nqi thiab tawm kev lees paub ntawm electrodes, ua kom lub roj teeb tawm thiab kev ua haujlwm.

Cov txiaj ntsig ntawm kev ntxiv cov ntsiab lus sib txawv ntawm cov pa roj carbon nanotubes (CNT) thiab cov pa roj carbon dub ntawm kev ua haujlwm ntawm electrochemical ntawm cov phaj tsis zoo ntawm cov hlau lead-acid roj teeb tau kawm.Ntxiv qhov tsim nyog ntawm CNTs tuaj yeem ua rau cov pore ntim ntawm qhov tsis zoo electrode, txhim kho cov khoom siv morphology ntawm cov khoom siv, ua kom cov khoom me me ntau dua, thiab txhim kho cov tshuaj tiv thaiv electrochemical kinetic kev ua tau zoo.Thaum 0.5% CNT tau ntxiv, thawj lub peev xwm tawm ntawm 1 C tau nce los ntawm 3%, thiab lub neej ntawm cov phaj electrode ntawm 2C thiab 60s lub voj voog tawm tau ze li ob npaug.Cov teebmeem ntawm ntau hom thiab cov ntsiab lus ntawm cov pa roj carbon nanotubes ntxiv rau qhov tsis zoo electrode ntawm lead-acid roj teeb nyob rau saum npoo morphology ntawm electrode phaj thiab kev ua haujlwm ntawm lub roj teeb tau sim kawm.

Cov kev sim qhia tau hais tias cov pa roj carbon nanotubes tuaj yeem txhawb nqa kev faib tawm ntawm cov ntaub ntawv nquag thiab tsim kom muaj txiaj ntsig zoo ntawm peb-dimensional conductive network;carbon nanotubes tuaj yeem txhim kho cov roj teeb ua haujlwm, thiab lub peev xwm pib ntawm lub roj teeb tuaj yeem nce mus txog 6.8%.Lub peev xwm tuaj yeem nce ntxiv ntawm qhov kub tsis tshua muaj -15 ° C 20.7%.Nws tuaj yeem txhim kho lub peev xwm tuav tau ntawm lub roj teeb.

Cov tshuaj tua kab mob ntau lub phab ntsa carbon nanotubes tau ntxiv rau cov khoom siv anode ntawm cov roj ntsha lead-acid, ua rau hauv electrodes, thiab cov yam ntxwv ntawm lub voj voog nyob rau hauv cov nqi sib txawv thiab tawm tam sim no raug kuaj.Cov nyhuv ntawm cov pa roj carbon nanotubes ntawm lub peev xwm, lub voj voog lub neej thiab kev ua haujlwm tau tshawb xyuas X-ray diffraction tsom xam pom tias tsim PbO2 nyob rau hauv lub phaj anode, thiab qhov sib ntxiv ntawm ntau phab ntsa carbon nanotubes nyob rau hauv lub phaj anode tuaj yeem txhim kho kev siv tus nqi ntawm active. cov ntaub ntawv thiab zoo inhibit qhov txo ntawm efficiency.
