Dab tsi ua rau graphite cov chemistry kom haum rau cov electrodes?
Graphite's fineed crystal qauv (nrog carbon atoms teem rau hauv cov qauv hexagonal) tso cai rau lithium ions kom swb) tsis muaj kev puas tsuaj loj.
Cov qauv kev ruaj khov ua kom ruaj khov uas lub electrode tuaj yeem yeb ntau txhiab tus nqi {{kev tawm mus ncig ua tsis tau muaj kev ua tsis tau zoo. Furthermore, graphite is chemically stable in the non-aqueous electrolytes used in lithium-ion batteries (LIBs) (typically carbonate-based solvents containing lithium salts, such as LiPF₆), and does not react violently with the electrolyte, thereby contributing to improved battery safety and cycle life.
Txawm li cas los xij, Graphite kuj ntsib ob peb qhov kev txwv:
Piv rau cov khoom siv anode tshiab xws li silicon (uas tuaj yeem ncav cuag 4200 mAh / g) lossis lithium hlau, graphite muaj qhov muaj peev xwm tsawg.
Ntawm cov nqi them siab lossis qis dua kub, graphite tuaj yeem nthuav qhia teeb meem xws li lithium plating, uas tuaj yeem txo cov roj teeb kev ua tau zoo thiab kev nyab xeeb.
Kev ua lag luam thiab yav tom ntej sib
Graphite yog cov khoom siv anode feem ntau cov khoom siv hauv kev ua lag luam lithium {{} ion roj teeb, suav rau ntau tshaj 90% ntawm anode siv. Nrog kev loj hlob sai ntawm lub tsheb hluav taws xob kev lag luam thiab lub zog cia kev lag luam, thov kom muaj roj teeb el graphite yog xav kom nce ntxiv hauv lub xyoo dhau los. Qhov no yog kev tsav tsheb nce ntxiv cov peev txheej ntawm graphite mining thiab hluavtaws graphite ntau dua, cov txheej txheem, thiab lwm yam khoom anode.
