Kev Taw Qhia:
Cov roj teeb lithium ternary thiabroj teeb lithium hlau phosphatePuas yog ob hom roj teeb lithium tseem ceeb uas tam sim no siv dav hauv cov tsheb fais fab, cov tshuab khaws cia hluav taws xob thiab lwm yam khoom siv hluav taws xob. Tab sis koj puas tau nkag siab txog lawv cov yam ntxwv thiab qhov sib txawv? Lawv cov tshuaj lom neeg sib xyaw, cov yam ntxwv kev ua tau zoo thiab cov teb siv sib txawv heev. Cia peb kawm ntxiv txog lawv nrog Heltec.
Cov khoom siv sib xyaw:
Lub roj teeb lithium ternary: Cov khoom siv electrode zoo feem ntau yog nickel cobalt manganese oxide (NCM) lossis nickel cobalt txhuas oxide (NCA), uas yog tsim los ntawm nickel, cobalt, manganese lossis nickel, cobalt, txhuas thiab lwm yam hlau oxides, thiab cov electrode tsis zoo feem ntau yog graphite. Ntawm lawv, qhov piv ntawm nickel, cobalt, manganese (lossis txhuas) tuaj yeem hloov kho raws li qhov xav tau tiag tiag.
Lub roj teeb lithium hlau phosphate: lithium hlau phosphate (LiFePO₄) yog siv ua cov khoom siv electrode zoo, thiab graphite kuj siv ua cov electrode tsis zoo. Nws cov tshuaj lom neeg muaj pes tsawg leeg ruaj khov, thiab nws tsis muaj cov hlau hnyav thiab cov hlau tsis tshua muaj, uas yog tus phooj ywg zoo rau ib puag ncig.
Kev them nqi thiab kev tso tawm kev ua tau zoo:
Lub roj teeb lithium ternary: them sai thiab tawm sai, tuaj yeem hloov kho rau qhov them thiab tawm tam sim no siab, tsim rau cov khoom siv thiab cov xwm txheej uas muaj qhov xav tau siab rau kev them ceev, xws li cov tsheb fais fab uas txhawb nqa kev them ceev. Hauv qhov chaw kub qis, nws qhov kev ua haujlwm them thiab tawm kuj zoo heev, thiab qhov poob peev xwm me me.
Lub roj teeb lithium hlau phosphate: qhov them thiab tso tawm qeeb qeeb, tab sis kev ua haujlwm ntawm lub voj voog them thiab tso tawm ruaj khov. Nws tuaj yeem txhawb nqa kev them nqi siab thiab tuaj yeem them tag nrho hauv 1 teev ntawm qhov ceev tshaj plaws, tab sis qhov kev them thiab tso tawm zoo feem ntau yog li ntawm 80%, uas qis dua me ntsis ntawm cov roj teeb lithium ternary. Nyob rau hauv qhov kub qis, nws cov kev ua tau zoo poob qis heev, thiab lub roj teeb muaj peev xwm khaws cia tsuas yog 50% -60%.
Lub zog ceev:
Lub roj teeb lithium ternary: Lub zog ceev yog qhov siab heev, feem ntau ncav cuag ntau dua 200Wh / kg, thiab qee cov khoom siv siab heev tuaj yeem tshaj 260Wh / kg. Qhov no tso cai rau cov roj teeb lithium ternary khaws cia ntau lub zog ntawm tib qhov ntim lossis qhov hnyav, muab kev tsav tsheb ntev dua rau cov khoom siv, xws li hauv cov tsheb fais fab, uas tuaj yeem txhawb nqa cov tsheb kom mus deb dua.
Lub roj teeb lithium hlau phosphate: Lub zog ceev yog qhov tsawg, feem ntau nyob ib puag ncig 110-150Wh / kg. Yog li ntawd, txhawm rau kom ua tiav qhov kev tsav tsheb zoo ib yam li cov roj teeb lithium ternary, cov roj teeb lithium hlau phosphate yuav xav tau qhov ntim lossis qhov hnyav dua.
Lub neej voj voog:
Lub roj teeb lithium peb txheej: Lub neej voj voog luv luv, nrog rau tus lej voj voog theoretical ntawm kwv yees li 2,000 zaug. Thaum siv tiag tiag, lub peev xwm yuav tau poob qis mus txog li 60% tom qab 1,000 lub voj voog. Kev siv tsis raug, xws li overcharging lossis discharge, thiab siv rau hauv qhov chaw kub siab, yuav ua rau lub roj teeb puas sai dua.
Lub roj teeb lithium hlau phosphate: Lub neej ntev, nrog ntau dua 3,500 lub sijhawm them thiab tso tawm, thiab qee lub roj teeb zoo tuaj yeem ncav cuag ntau dua 5,000 zaug, uas yog sib npaug rau ntau dua 10 xyoo ntawm kev siv. Nws muaj kev ruaj khov zoo, thiab kev ntxig thiab tshem tawm ntawm lithium ions muaj qhov cuam tshuam me ntsis rau lub lattice, thiab muaj kev thim rov qab zoo
Kev Nyab Xeeb:
Lub roj teeb lithium ternary: tsis ruaj khov thermal, yooj yim ua rau thermal khiav tawm hauv qhov kub siab, overcharge, luv luv Circuit Court thiab lwm yam mob, ua rau muaj kev pheej hmoo siab ntawm kev kub hnyiab lossis txawm tias tawg. Txawm li cas los xij, nrog rau kev nce qib ntawm thev naus laus zis thiab kev txhawb nqa ntawm kev ntsuas kev nyab xeeb, xws li kev siv cov txheej txheem tswj roj teeb siab dua thiab kev ua kom zoo dua ntawm cov qauv roj teeb, nws txoj kev nyab xeeb kuj tseem txhim kho tas li.
Lub roj teeb lithium hlau phosphate: kev ruaj khov zoo thermal, cov khoom siv electrode zoo tsis yooj yim tso cov pa oxygen ntawm qhov kub siab, thiab yuav tsis pib lwj mus txog 700-800 ℃, thiab yuav tsis tso cov pa oxygen thaum ntsib kev cuam tshuam, kev tho, luv luv Circuit Court thiab lwm yam xwm txheej, thiab tsis yooj yim rau kev kub hnyiab, nrog kev ua haujlwm nyab xeeb siab.
Tus nqi:
Lub roj teeb lithium ternary: vim tias cov khoom siv electrode zoo muaj cov khoom siv hlau kim xws li nickel thiab cobalt, thiab cov txheej txheem ntau lawm xav tau siab, thiab cov kev cai ib puag ncig kuj nruj dua, yog li tus nqi kuj siab.
Lub roj teeb lithium hlau phosphate: tus nqi ntawm cov khoom siv raw yog qis dua, cov txheej txheem tsim khoom yog yooj yim, thiab tag nrho cov nqi muaj qee qhov zoo. Piv txwv li, hauv cov tsheb fais fab tshiab, cov qauv uas muaj roj teeb lithium hlau phosphate feem ntau tus nqi qis dua.
