18650 lithium-ion roj teeb kev faib tawm
18650 lithium-ion roj teeb ntau lawm yuav tsum muaj cov kab kev tiv thaiv los tiv thaiv lub roj teeb ntawm overcharged thiab overdischarged. Tau kawg qhov no hais txog cov roj teeb lithium-ion yog qhov tsim nyog, uas tseem yog qhov tsis zoo ntawm cov roj teeb lithium-ion, vim tias cov khoom siv hauv cov roj teeb lithium-ion yog cov khoom siv lithium cobaltate, thiab lithium cobaltate cov khoom siv lithium-ion roj teeb tsis tuaj yeem tso tawm. ntawm qhov siab tam sim no, kev nyab xeeb tsis zoo, los ntawm kev faib tawm ntawm 18650 lithium-ion roj teeb tuaj yeem raug cais raws li hauv qab no.
Lub hwj chim hom roj teeb thiab lub zog hom roj teeb. Lub zog hluav taws xob hom roj teeb muaj cov yam ntxwv ntawm lub zog siab ceev thiab tseem ceeb rau cov khoom siv hluav taws xob siab; Lub hwj chim hom roj teeb yog tus cwj pwm los ntawm lub zog siab ceev thiab tseem ceeb heev rau cov khoom siv hluav taws xob sai sai thiab cov zis. Lub zog-zog lithium-ion roj teeb yog nrog los ntawm kev tshwm sim ntawm plug-in hybrid tsheb. Nws yuav tsum muaj lub zog siab dua khaws cia hauv lub roj teeb, uas tuaj yeem txhawb nqa qhov kev ncua deb ntawm kev tsav hluav taws xob ntshiab, tab sis kuj yuav tsum muaj lub zog zoo dua qub, thiab nkag mus rau hom hybrid ntawm lub zog qis.
Kev nkag siab yooj yim, hom hluav taws xob zoo ib yam li cov neeg khiav dej num marathon, kom muaj kev ua siab ntev, yog qhov yuav tsum tau muaj peev xwm, qhov kev ua haujlwm siab tam sim no yuav tsum tsis siab; ces lub hwj chim hom yog cov sprinters, sib ntaus sib tua yog tawg hwj chim, tab sis endurance kuj yuav tsum muaj, txwv tsis pub lub peev xwm yog heev me me yuav tsis khiav deb.
Cov roj teeb lithium-ion tau muab faib ua kua lithium-ion roj teeb (LIB) thiab polymer lithium-ion roj teeb (PLB).
Cov roj teeb lithium-ion ua kua siv cov kua electrolyte (uas feem ntau yog siv hauv cov roj teeb hluav taws xob niaj hnub no). Polymer lithium-ion roj teeb siv cov khoom siv hluav taws xob polymer hloov pauv, uas tuaj yeem ua rau qhuav lossis gel, thiab feem ntau tam sim no siv polymer gel electrolytes. Hais txog cov roj teeb hauv lub xeev, nruj me ntsis hais lus, nws txhais tau hais tias ob qho tib si electrodes thiab electrolytes yog khoom.
Muab faib ua: cylindrical, mos pob, square.
Cylindrical thiab square txheej ntim feem ntau yog hlau lossis txhuas plhaub. Soft pack txheej ntim yog aluminium yas zaj duab xis, qhov tseeb, pob muag muag kuj yog ib hom square, kev lag luam yog accustomed rau aluminium yas zaj duab xis ntim hu ua mos pob, qee cov neeg kuj hu ua mos pob roj teeb polymer roj teeb.
Txog lub cylindrical lithium-ion roj teeb, nws tus qauv tooj feem ntau yog 5 tus lej. Thawj ob tus lej yog lub cheeb ntawm lub roj teeb, thiab qhov nruab nrab ob tus lej yog qhov siab ntawm lub roj teeb. Chav tsev yog millimeter. Piv txwv li, 18650 lithium-ion roj teeb, uas muaj txoj kab uas hla ntawm 18 hli thiab qhov siab ntawm 65 hli.
Anode cov ntaub ntawv: lithium hlau phosphate ion roj teeb (LFP), lithium cobalt acid ion roj teeb (LCO), lithium manganate ion roj teeb (LMO), (binary roj teeb: lithium nickel manganate / lithium nickel cobalt acid), (ternary: lithium nickel cobalt manganate) ion roj teeb (NCM), lithium nickel cobalt aluminium acid ion roj teeb (NCA)
Cov ntaub ntawv tsis zoo: lithium titanate ion roj teeb (LTO), graphene roj teeb, nano carbon fiber roj teeb.
Lub tswv yim ntawm graphene hauv kev lag luam cuam tshuam yog hais txog cov roj teeb graphene, piv txwv li graphene slurry hauv cov ncej, lossis graphene txheej ntawm lub diaphragm. Lithium nickel-acid thiab magnesium-based roj teeb yog qhov tsis muaj nyob hauv khw.
