Raws li lub ntiaj teb xav tau lub zog txuas ntxiv mus ntxiv, Hnub Ci ntawm tes yog txav mus rau kev ua haujlwm siab dua, tus nqi qis dua thiab ntau tus nqi ntawm ib puag ncig. Lithium iron phosphate (LFP) cov hlwb hlwb tau maj mam dhau los ua qhov kev nyab xeeb tshaj plaws hauv kev nyab xeeb rau lawv txoj kev nyab xeeb heev, lub neej ntev thiab ruaj khov. Hauv kev tshawb nrhiav thiab kev tsim khoom thiab kev tsim khoom thiab kev xaiv cov khoom siv solar, cov khoom siv ncaj qha txiav txim siab tag nrho cov kev ua tau zoo ntawm lub roj teeb. Kab lus no yuav xaiv cov peev txheej tseem ceeb ntawm Lithium Iron phosphate cov ntaub ntawv hauv nruab hnub ci los ntawm cov ntaub ntawv ntawm cov khoom siv hluav taws xob hnub ci, electrolytes, diaphragms, ntaub ntawv ntim khoom.
Cov Khoom Siv Hluav Taws Xob Cov Khoom Siv Hluav Taws Xob: Cov ntsiab lus tseem ceeb ntawm Lithium Iron Phosphate
Lithium Iron phosphate (LIFEPOO₄), raws li cov khoom siv hluav taws xob zoo ntawm LFP roj teeb, muaj siab tshaj plaws lub peev xwm (txog 170mAh / g), lub neej zoo heev. Piv nrog cov tsoos cov khoom siv (xws li NCM, NCA), LFP tsis tau muaj kev khiav tawm hauv qhov chaw kub nyob ib puag ncig, thiab nws txoj kev nyab xeeb tau txhim kho. Tsis tas li ntawd, LFP muaj ntau cov khoom siv raw thiab tus nqi qis, uas ua tau raws li qhov xav tau ntawm loj- ntsuas cov ntawv thov kev lag luam loj. Yog li ntawd, nyob rau hauv lub hnub ci zog cia siv lub zog, LFP cov ntaub ntawv electrode tau dhau los ua qhov kev xaiv tseem ceeb.
Electrolyte: High Ionic conductivity thiab ruaj khov
Electrolyte yog qhov tseem ceeb rau ion thauj hauv lub roj teeb, uas cuam tshuam ncaj qha cuam tshuam nrog kev them nyiaj thiab kev tawm tsam thiab kev nyab xeeb ntawm lub roj teeb. Nyob rau tam sim no, LFP cov hlwb hnub ci feem ntau siv cov kua electrolytes, xws li cov tshuaj carbonate nrog cov ntsev lithium (xws li lipf₆). Txawm li cas los xij, kua electrolytes muaj kev pheej hmoo ntawm to thiab flammability, yog li khoom electrolytes lossis oxide khoom electrolytes) tau dhau los ua cov kev tshawb fawb hauv nruab nrab. Cov khoom siv hluav taws xob tsis tuaj yeem txhim kho kev nyab xeeb ntawm cov roj teeb, tab sis tseem ua kom yooj yim lub roj teeb thiab nce lub zog ntom ntom ntom.
Diaphragm: ib qho kev cuam tshuam tseem ceeb kom ntseeg tau roj teeb
Lub diaphragm plays lub luag haujlwm ntawm kev cais cov hluav taws xob zoo thiab tsis muaj kev tiv thaiv luv luv hauv lub roj teeb, thaum tso cai lithium ions kom dhau dawb paug. LFP cov hlwb hnub ci feem ntau siv Polyolefas Diaphragms (xws li PE, PP) vim tias lawv cov tshuaj ruaj khov thiab tshuab muaj zog. Nyob rau hauv xyoo tsis ntev los no, ceramic co siv dia dia dia dia dia dia dia dia dia dia lub zog cia khoom siv roj teeb nrog kev nyab xeeb kev nyab xeeb txog lawv qhov kev kub siab ua tau thiab kev tawm tsam siab.
Ntim Khoom: Tus yuam sij kom txuas ntxiv roj teeb lub neej
Cov ntaub ntawv ntim ntim ntawm cov yeeb yaj kiab ci ncaj qha cuam tshuam lawv cov huab cua tsis kam thiab lub neej pabcuam. LFP roj teeb feem ntau encapsulated nrog aluminium {1} Yas yeeb yaj kiab lossis iav los tawm tsam tus txheej txheem ntawm ultraviolet rays, noo thiab ntsuas kub. Ntawm lawv, iav ntim tau dav hauv cov tshuab sab nraum zoov photovoltaic vim nws cov huab cua zoo heev thiab muaj zog dua.
Hauv cov ntsiab lus, cov khoom xaiv ntawm Lithium Iron Phosium phosphote solar hlwb yuav tsum tau txiav txim siab kev nyab xeeb, nqi thiab kev ua tau zoo. Nrog kev nce qib ntawm cov ntaub ntawv txuj ci, LFP roj teeb yuav tsum ua lub luag haujlwm ntau dua hauv lub neej yav tom ntej thiab txhawb kev hloov pauv ntiaj teb.
