Cov kws tshawb fawb German tsis tas yuav xav tsis thoob. Karlsruhe Institute of Technology tau tshaj tawm tsab xov xwm tshaj tawm txog kev kawm nthuav dav. Nws hloov tawm tias qhov tsis muaj roj teeb lithium-ion tuaj yeem txhim kho tau zoo siv cov qe zoo tib yam.
Hauv qhov tseeb niaj hnub no, cov qe qe feem ntau mus pov tseg. Nws yog ib feem siv nyob rau hauv perfumery thiab txawm nyob rau hauv lub electronics kev lag luam rau kev tsim khoom ntawm ionistors (supercapacitors), tab sis nyob rau hauv loj qhov ntau nws muab pov rau hauv landfills. Lub caij no, lub plhaub muaj cov ntxeem tau hauv daim ntawv ntawm calcium carbonate (CaCO3) thiab cov yeeb yaj kiab uas muaj protein ntau, thiab cov ntaub ntawv ntxeem tau paub tias muaj kev xav tau ntau hauv kev tsim cov roj teeb lithium-ion.
Lub koom haum Helmholtz Ulm, nyob rau hauv kev txhawb nqa ntawm Karlsruhe Institute of Technology thiab koom tes nrog cov npoj yaig los ntawm Australia, tau teeb tsa kev kawm txog cov khoom ntawm cov qe qe ua cov khoom siv rau electrodes hauv lithium-ion roj teeb. Cov txiaj ntsig kev tshawb fawb tau luam tawm nyob rau hauv phau ntawv journal Dalton Transactions ntawm Royal Society of Chemistry.
Txoj kev tshawb no pom tias crushed egghell electrodes yog zoo haum rau ua cov nqi qis lithium-ion roj teeb siv anhydrous electrolyte. Kev sim roj teeb nrog lub plhaub qe electrode, tom qab 1000 tus nqi thiab tawm mus, poob tsuas yog 8% ntawm nws lub peev xwm qub. Qhov no yog ntau tshaj li tus yam ntxwv zoo rau lub roj teeb. Nws yuav nthuav kom paub tias ib tug neeg yuav siv cov cuab yeej no hauv kev xyaum. Txog tam sim no, cov kws tshawb fawb tseem nyob twj ywm ntawm qhov teeb meem no.
