Graphene Lithium Battery Technology Ua Tau Lwm Txoj Kev Txhim Kho

Muaj cov ntawv tshaj tawm xov xwm hais tias graphene lithium roj teeb khoom hu ua" Kene King" raug tso tawm hauv Beijing. Daim ntawv tshaj tawm hais tias" cov khoom' s tsaws tau qhib lub hnub nyoog ntawm graphene hauv lub zog hluav taws xob, thiab ua pov thawj tias cov pa roj carbon txhuam lub zog graphene qhov kev vam meej ntawm ob qhov tseem ceeb ntawm kev npaj thiab graphene-coated lithium roj teeb cov ntaub ntawv zoo thiab tsis zoo tau ua tiav qhib qhov chaw thov ntawm graphene hauv kev siv hluav taws xob cov roj ntsha lithium, cov roj teeb lithium thiab cov roj teeb lithium hauv thaj chaw ntawm lub zog cia."

Graphene lithium roj teeb yog lub tswvyim tshiab uas tau rov ua dua tshiab los ntawm kev tshaj xov xwm. Nws tau teeb tsa ib qho tom qab ib qho hauv cov khoom lag luam, uas tau cuam tshuam cov leeg ntawm ntau tus neeg thiab cov nyiam ntawm ntau lub tuam txhab. Cov neeg muaj txuj ci ntsig txog scientific thiab thev naus laus zis thoob plaws ntiaj teb tau sib tham thiab tshawb txog daim ntawv thov ntawm graphene, thiab kev ua tiav ntawm kev tshawb fawb thiab thev naus laus zis thiab cov tswv yim muaj peev xwm tau muab qhia tas li, tshwj xeeb tshaj yog siv cov roj teeb lithium. Muaj ntau dua virtual tab sis tsawg tiag tiag. Txog tam sim no, tsis muaj cov khoom lag luam raug muag muag hauv khw. Cov. Tsawg kawg yog li tam sim no, qhov tawg ntawm cov khoom lag luam technology saum toj saud tso cai rau peb kom pom nrog peb lub qhov muag qhov khoom lag luam tiag tiag uas graphene tau thov rau lithium roj teeb. Nws cia siab tias graphene lithium roj teeb uas peb pom tsis yog piv txwv los ua pov thawj cov ntaub ntawv tshawb fawb txog kev tshawb fawb, tab sis cov khoom lag luam siab siab uas tuaj yeem pib ua kom sai sai rau lub ntiaj teb.

Los ntawm daim duab ntawm cov khoom tso tawm, tuaj yeem pom tias cov khoom lag luam tshiab yog cov khoom siv hluav taws xob nrog lub ntim sib npaug nrog cov roj teeb hluav taws xob dav dav dav (4800mAh). Muaj ntau lub txhab fais fab txhab nyiaj tsim khoom hauv khw muaj peev xwm ntawm 4800 mAh. Bau yuav tsum yog tus me dua. Yuav ua li cas lub zog khoom hluav taws xob pom cov kev cia siab ntawm nws daim ntawv thov hauv hluav taws xob tsheb? Yog tias cov khoom lag luam zoo ib yam li cov khoom siv lithium roj teeb lub zog siv, siv ob lub 18650 roj teeb nrog lub peev xwm ntawm 2400mAh (rau lub sijhawm tsuas yog qhov no tuaj yeem kwv yees), tom qab ntawd nws cov khoom siv loj yuav tsum yooj yim heev kom tiav, thiab cov khoom yuav tsis siv rau hauv cov tsheb fais fab tom qab sib sau ua ke. Qhov teeb meem loj li cas.

Raws li peb paub, rau lub roj teeb 2400mAh 18650, nws lub peev xwm ntim tau ntau dua 500 watt-teev rau ib lim, thiab lub peev txheej tivthaiv muaj peev xwm ncav ntau dua 180 watt-teev rau ib phaus, uas zoo ib yam li Panasonic siv hauv Tesla qhov siab -yog khoom siv hluav taws xob tsheb. Piv nrog 18650 roj teeb nrog lub peev xwm ntawm 3100mAh, lub peev xwm me ntsis qis dua, tab sis lwm peb txoj cai nyob deb tshaj nws. Piv nrog roj teeb lithium iron phosphate siv hauv tsheb hluav taws xob BYD hluav taws xob, qhov feem cuam ntawm lub zog hluav taws xob muaj zog dua. Yog kawg, tib lub roj teeb tau sib koom ua ke. Kuv tsis paub yog tias kuv tuaj yeem ncav cuag tam sim no. Txawm hais tias tus nqi ntawm lwm qhov khoom siv fais fab tuaj yeem ua tau zoo ib yam li cov tuam txhab fais fab uas twb muaj lawm, nws tsis paub meej thaum lub sijhawm sau npe, thiab tus nqi kuj tseem tsis tau paub. Yog tias nws tsis yog tus qauv ntim hom ntawm ob 18650 roj teeb, yuav ua li cas thov lawv rau hluav taws xob tsheb, txoj cai roj teeb tsis meej, thiab nws tsis tuaj yeem tham txog nws tam sim no. Hauv ntej, huab hwm coj ntau lawm thiab teev cov roj teeb yog qhov tseem ceeb. Cov khoom zoo tuaj yeem sawv kev sim ntawm kev ua lag luam thiab dhau los ua txoj moo zoo ntawm cov lag luam thiab cov neeg siv khoom.

Raws li cov lus ceeb toom, piv nrog cov roj teeb zoo tib yam, cov roj teeb lithium-ion tsis tuaj yeem ua tiav xwb tus nqi nrawm thiab tso tawm tsis pub dhau 15 feeb nyob rau hauv qhov xwm txheej ntawm 5C, tab sis kuj tseem muaj cov roj av graphene lithium tuaj yeem ua haujlwm ntawm -30 ~ 80 ℃, thiab cov kev pab cuam lub neej yog li Txog 3500 zaug. Los ntawm kev sim ntawm thaj chaw ntawm lub rooj sib tham xovxwm, lub sijhawm them ntawm" King" yog 15 feeb, uas yog 1/24 ntawm cov khoom siv them nqi dav dav. Peb txoj cai tswjfwm ntawm King En' s cov khoom siv yog qhov tseem ceeb cov cai tseem ceeb uas lub tsheb hluav taws xob xav tau los nrog kev nrawm thaum lub sijhawm. Qhov tsuas yog ib qho uas yuav tsum tau kuaj hauv lub rooj sib tham nrog xovxwm tau them ceev. Lub siab thiab tsis kub nyob ib puag ncig them thiab lub peev xwm thiab lub neej ntawm 3,500 zaug tsis muaj nyob ntawm qhov chaw. Ua qauv qhia, lub vas nthiv them cov txiaj ntsig yog qhov tseeb ntseeg. Koj yuav tsum paub tias 2A daim roj teeb siv ntawm peb lub xov tooj txawb' s lub zog hluav taws xob hluav taws xob muaj qhov kub heev thaum them nyiaj. Qhov no 4800 mAh lithium roj teeb lub zog hluav taws xob cov khoom siv 5C rau them. Thaum nws nce mus txog ntau tshaj 20 amperes, tsawg kawg Kuv tsis tau' t pom tias kub npaum li cas. Hais lus nruj me ntsis, 15 feeb them nyiaj tsuas yog ua tiav 4C yam kev mob, 5C yuav tsum yog 12 feeb. 10C yuav tsum ncav cuag 6 feeb. Rau lub tsheb fais fab, nws yog qhov dag kom ua txhaum 6-feeb them tas nrho. Vim li cas koj thiaj li yuav tsum sib piv lub sijhawm roj ntxiv nrog roj tsheb. Yog tias nws' s sijhawm rov qab them rau tom qab nres tsheb, koj puas xav tias nws tsim nyog los sib piv lub sijhawm roj ntxiv nrog roj tsheb? Ntawm chav kawm, rau cov tsheb ntiav thiab tsheb npav, lub sijhawm them yuav tsum luv li sai tau. Cov neeg yuav khoom yuav tos koj kom them li ib nrab teev. Tsis muaj ib tug twg los tos. Qhov no yog qhov kev zam.

Piv nrog kev them nyiaj ceev ntawm lithium roj teeb rau hluav taws xob tsheb, cov tib neeg muaj kev cia siab ntau dua uas graphene tuaj yeem ua rau muaj peev xwm ntau ntxiv ntawm lithium roj teeb. Hauv xyoo 2015, tsab ntawv tshaj tawm txog kev vam meej ntawm kev txhim kho graphene super roj teeb hauv Spain tau lees tias lub sijhawm them tag nrho hauv 8 feeb tuaj yeem tso cai rau lub tsheb fais fab mus ncig 1,000 mais nrog lub zog siv txog li tsib mus rau rau pua teev nyob rau ib teev. Txog tam sim no, lub ntsej muag tseeb ntawm cov khoom tsis tau pom dua. Tsis hais txog 8 feeb, nws yog qhov zoo dua los khiav 1000 mais nrog lub zog tag nrho rau sijhawm ntxiv! Suav haj yam haj yam muaj plhus hais tias. Hauv peb lub teb chaws 13 Txoj Kev Npaj Thib Tsib, lub zog hluav taws xob ntawm lithium roj teeb cia siab tshaj 300 watt-teev rau ib phaus hauv xyoo 2020, thiab cov roj teeb cia siab tias tsawg dua 0.6 yuan ib watt-teev. Kev txiav txim siab los ntawm cov ntaub ntawv luam tawm ntawm cov lag luam roj teeb roj teeb hauv tuam txhab, xws li txoj cai tuaj yeem ua tiav. Tam sim no koj tuaj yeem pom hluav taws xob tsheb uas tuaj yeem taug kev deb 400 mais ntawm ib zaug xwb, thiab los ntawm ntawd, koj tuaj yeem pom lub tsheb fais fab tuaj yeem taug kev 800 km ntawm ib tus nqi.

Lub neej ntev ntawm cov roj av ntawm graphene lithium roj teeb kuj coj kev cia siab rau daim ntawv thov lub zog ntawm lub tsheb hluav taws xob. Yog tias nws tau them tag nrho hauv 30 feeb, nws lub neej kev ua haujlwm yuav ntau dua 3,500 zaug. Kuv cia siab tias nws yuav siv tau rau hluav taws xob tsheb sai li sai tau, kom hluav taws xob tsheb nrog lub zog txuag hluav taws xob muaj peev xwm khiav tau thoob lub teb chaws, kom tus nqi siv hluav taws xob tsheb tau txais qis dua thiab qis dua, ua rau lub tsheb hluav taws xob muaj dav dua , thiab ua kev them nqi nres tsheb yooj yim dua txhua lub sijhawm, nyob qhov twg. Muaj kev yooj yim, ua rau lub xov tooj txawb hluav taws xob thiab lub zog txuag hluav taws xob ua cov qauv khoom siv rau lub tsheb fais fab, ua kom them thiab khaws cov hluav taws xob tsheb thiab lub zog siv hluav taws xob, muaj tswv yim, thiab tsis siv neeg cov txheej txheem los tswj lub suab sib luag. Qhov no yog ncaj qha los ntawm graphene lithium roj teeb Hauv nqe lus ntawm cov khoom' s ultra-siab mus los lub neej muaj nuj nqi, peb feem ntau xav pom cov ntawv thov kev cia siab.
