Grapheneyog cov khoom siv ob qhov ntev uas cov pa roj carbon atoms tau qee lub sijhawm sib xyaw hauv cov ntoo ntxaij ntoo nrog SP2 cov pob zeb sib txuas. Graphene tsuas yog ib qho pa roj carbon atom tuab thiab muaj cov khoom siv zoo heev rau lub cev xws li loj theoretical tshwj xeeb thaj chaw thaj chaw, hluav taws xob muaj hluav taws xob ntau, qhov ntsuas kub siab, siab Hluas' s modulus, thiab lwm yam. ntau daim teb xws li kev kho tshuab, kev txuag hluav taws xob, catalysis, cov khoom siv hluav taws xob thiab kev kho ib puag ncig.
Hnubpoob graphene muaj cov ntu ua haujlwm zoo ib yam li cov pa roj carbon nanotubes thiab muaj cov hluav taws xob zoo zoo ib yam. Nyob rau tib lub sijhawm, ob lub dav hlau qauv tsim ua kom nws tuaj yeem tsim qhov taw tes-taw-rau ntawm qhov kev sib cuag nrog cathode cov khoom tawm. Yog li, nws xav kom hloov cov roj carbon nanotubes lossis siv nrog kev sib xyaw nrog cov roj carbon nanotubes hauv kev ua haujlwm ntawm cov roj teeb lithium-ion, thiab nce lub zog ntawm cov roj teeb uas yog txo cov kev tiv tauj.
Nyob rau qib no, daim ntawv thov ntawm graphene hauv thaj chaw ntawm cov roj ntsha lithium-ion feem ntau yog nyob ntawm cov nruab nrab conductive ntawm qhov zoo electrode sab, ntau dua li cov khoom siv electrode tseem ceeb. Txawm li cas los xij, vim muaj kev lag luam loj heev rau lithium-ion roj teeb rau cov hluav taws xob ntshiab thiab pib roj teeb rau cov hluav taws xob hybrid, qhov kev thov rau graphene hauv daim teb no tseem muaj ntau.
Peb,TOB Tshiab Zog, raws li tus kws tshaj lij cov roj ntsha lithium ion roj teeb tsim tshuab thiab cov khoom siv khoom lag luam, uas tau tshwj xeeb hauv daim teb no rau ntau dua 17 xyoo.if koj nthuav nrog cov khoom siv lithium ion raw khoom tshiab thiab ua tshuab, txais tos hu rau kuv.
