Taw qhia:
Ternary lithium roj teeb thiablithium hlau phosphate roj teebyog ob yam tseem ceeb ntawm lithium roj teeb tam sim no siv dav hauv tsheb fais fab, lub zog cia thiab lwm yam khoom siv hluav taws xob. Tab sis koj puas tau nkag siab lawv cov yam ntxwv thiab qhov sib txawv? Lawv cov tshuaj muaj pes tsawg leeg, cov yam ntxwv ntawm kev ua tau zoo thiab daim ntawv thov teb yog qhov sib txawv. Cia peb kawm ntxiv txog lawv nrog Heltec.
Khoom muaj pes tsawg leeg:
Ternary lithium roj teeb: Cov khoom siv electrode zoo feem ntau yog npib tsib xee cobalt manganese oxide (NCM) lossis npib tsib xee cobalt aluminium oxide (NCA), uas yog tsim los ntawm npib tsib xee, cobalt, manganese lossis npib tsib xee, cobalt, txhuas thiab lwm yam hlau oxides, thiab qhov tsis zoo. electrode feem ntau yog graphite. Ntawm lawv, qhov piv ntawm nickel, cobalt, manganese (los yog txhuas) tuaj yeem hloov kho raws li qhov xav tau tiag tiag.
Lithium hlau phosphate roj teeb: lithium hlau phosphate (LiFePO₄) yog siv los ua cov khoom siv hluav taws xob zoo, thiab graphite kuj siv rau qhov tsis zoo electrode. Nws cov tshuaj muaj pes tsawg leeg yog qhov ruaj khov, thiab nws tsis muaj cov hlau hnyav thiab cov hlau tsis tshua muaj, uas yog ib puag ncig zoo.
Charge thiab tawm kev ua haujlwm:
Ternary lithium roj teeb: them ceev ceev thiab tso tawm ceev, tuaj yeem hloov mus rau qhov siab tam sim no thiab tawm, haum rau cov khoom siv thiab cov xwm txheej uas yuav tsum tau ua kom ceev ceev, xws li cov tsheb fais fab uas txhawb nqa ceev ceev. Nyob rau hauv qhov kub thiab txias ib puag ncig, nws cov nqi thiab kev ua haujlwm tawm kuj yog qhov zoo, thiab lub peev xwm poob yog me me.
Lithium hlau phosphate roj teeb: tus nqi qeeb qeeb thiab tso tawm nrawm, tab sis lub voj voog ruaj khov thiab kev ua haujlwm tawm. Nws tuaj yeem txhawb nqa tus nqi siab thiab tuaj yeem them tag nrho hauv 1 teev ntawm qhov ceev tshaj plaws, tab sis tus nqi thiab kev ua haujlwm tawm feem ntau yog nyob ib puag ncig 80%, uas yog qis dua li ntawm ternary lithium roj teeb. Nyob rau hauv qhov kub thiab txias, nws qhov kev ua tau zoo poob qis, thiab lub roj teeb muaj peev xwm tuav tau tsuas yog 50% -60%.
Zog ceev:
Ternary lithium roj teeb: Lub zog ceev yog qhov siab, feem ntau ncav cuag ntau tshaj 200Wh / kg, thiab qee cov khoom siab tshaj tuaj yeem tshaj 260Wh / kg. Qhov no tso cai rau ternary lithium roj teeb khaws cia ntau lub zog ntawm tib lub ntim lossis qhov hnyav, muab kev tsav tsheb ntev dua rau cov khoom siv, xws li hauv tsheb fais fab, uas tuaj yeem txhawb nqa tsheb mus ntev dua.
Lithium hlau phosphate roj teeb: Lub zog ceev yog qhov tsawg, feem ntau nyob ib ncig ntawm 110-150Wh / kg. Yog li ntawd, txhawm rau ua kom tiav qhov kev tsav tsheb zoo ib yam li ternary lithium roj teeb, lithium hlau phosphate roj teeb yuav xav tau lub ntim loj dua lossis hnyav dua.
Lub neej voj voog:
Ternary lithium roj teeb: Lub voj voog lub neej luv luv, nrog lub voj voog theoretical txog li 2,000 zaug. Hauv kev siv tiag tiag, lub peev xwm yuav tau lwj mus txog 60% tom qab 1,000 lub voj voog. Kev siv tsis raug, xws li overcharging los yog tso tawm, thiab siv nyob rau hauv ib puag ncig kub, yuav ua rau kom lub roj teeb puas.
Lithium hlau phosphate roj teeb: Lub neej ntev lub neej, nrog ntau tshaj 3,500 lub sij hawm them thiab tawm mus, thiab qee lub roj teeb zoo tuaj yeem ncav cuag ntau dua 5,000 zaug, uas yog sib npaug rau ntau tshaj 10 xyoo ntawm kev siv. Nws muaj kev ruaj ntseg zoo lattice, thiab kev ntxig thiab tshem tawm ntawm lithium ions muaj kev cuam tshuam me ntsis ntawm cov lattice, thiab muaj kev rov qab zoo.
Kev nyab xeeb:
Ternary lithium roj teeb: tsis zoo thermal stability, yooj yim ua rau thermal runaway nyob rau hauv siab kub, overcharge, luv luv Circuit Court thiab lwm yam kev mob, ua rau muaj kev pheej hmoo ntawm combustion los yog txawm tawg. Txawm li cas los xij, nrog kev nce qib ntawm kev siv thev naus laus zis thiab kev ntxiv dag zog rau kev ntsuas kev nyab xeeb, xws li kev siv cov roj teeb ntau dua thiab kev ua kom zoo ntawm cov qauv roj teeb, nws txoj kev nyab xeeb kuj tseem txhim kho tas li.
Lithium hlau phosphate roj teeb: zoo thermal stability, cov khoom zoo electrode tsis yooj yim rau tso pa tawm ntawm qhov kub thiab txias, thiab yuav tsis pib decompose kom txog rau thaum 700-800 ℃, thiab yuav tsis tso oxygen molecules thaum muaj kev cuam tshuam, puncture, luv Circuit Court thiab Lwm qhov xwm txheej, thiab tsis yog qhov ua rau muaj kev kub ntxhov, nrog rau kev ua haujlwm siab.
Tus nqi:
Ternary lithium roj teeb: vim tias cov khoom siv hluav taws xob zoo muaj cov khoom siv hlau kim xws li npib tsib xee thiab cobalt, thiab cov txheej txheem tsim khoom yuav tsum siab, thiab cov kev cai ib puag ncig kuj nruj dua, yog li tus nqi kuj tseem siab.
Lithium hlau phosphate roj teeb: tus nqi ntawm cov khoom siv raw yog qhov tsawg, cov txheej txheem tsim khoom yog qhov yooj yim, thiab tus nqi tag nrho muaj qee qhov zoo. Piv txwv li, nyob rau hauv lub zog tshiab tsheb, cov qauv nruab nrog lithium hlau phosphate roj teeb feem ntau kuj tsis tshua muaj nqi.
Xaus
Kev xaiv roj teeb nyob ntawm qhov tshwj xeeb ntawm daim ntawv thov. Yog tias xav tau lub zog ntau dua thiab lub roj teeb ntev dua, cov roj teeb lithium ternary yuav yog qhov kev xaiv zoo dua; Yog tias muaj kev nyab xeeb, ua haujlwm ntev thiab lub neej ntev yog qhov tseem ceeb, cov roj teeb lithium hlau phosphate yog qhov tsim nyog dua.
