Supercapacitors yog lub zog cia khoom siv uas ceev heev sai thiab tuaj yeem khaws lawv cov peev xwm cia los ntawm kaum ntawm txhiab tus them nyiaj. Lawv cov ntawv sau muaj xws li cov cuab yeej kev tsim kho rau cov tsheb fais fab.Thaum lawv lub khw tsis muaj zog li qub li roj teeb, thiab lawv tsis siv sij hawm ntev rau recharge - tab sis cov kev siv hauv cov tshuab supercapacitor ua rau lawv sib tw nrog cov roj teeb hauv ntau daim ntaub ntawv. Nyob rau hauv kev tshawb nrhiav lub npe hu ua "Cov Ntawv Cuam Tshooj 3D Printed Pseudocapacitive Electrodes nrog Ultrahigh MnO2 Loading," ib pawg neeg soj ntsuam ntawm UC Santa Cruz thiab Lawrence Livermore National Laboratory tau ua tiav kev ua haujlwm ntawm lub tshuab hluav taws xob supercapacitor.The electrode yog tsim los ntawm 3D printable graphene airgel, uas yog siv los ua cov txuam ntxeem ntxoo 3D nrog cov khoom siv fake capacitive.
Cov supercapacitors uas ua los ntawm cov electrodes muaj kev ruaj ntseg cyclic zoo thiab tswj kom muaj ntau tshaj li 90% ntawm thawj zaug ua haujlwm tom qab 20,000 tus nqi thiab tawm mus. Cov ntawv sau electrodes hauv 3D cia kom muaj tus nqi loj tsim, thiab lub graphene-based inks muab ultrahigh deg cheeb tsam, cov khoom hnyav, elasticity, thiab superior hluav taws xob conductivity.
