Indlela iibhetri zeLFP zisebenza ngayo
Iibhetri ze-LFP zisebenza ngokuhamba kwee-ion ze-lithium phakathi kwe-electrode ngexesha lokutshaja kunye nokukhupha imijikelezo. I-cathode iqukethe i-lithium iron phosphate, ngelixa i-anode isebenzisa i-graphic carbon kunye ne-metallic backing. Ngokungafaniyo nezinye iikhemistri ze-lithium -i-ion, i-LFP's polyanion structure yenza uthungelwano - olune-dimensional olunika uzinzo olukhethekileyo lwesakhiwo.
Isakhiwo sekristale ye-olivine ye-lithium iron phosphate inika ezi bhetri iinzuzo zazo zeempawu. Xa i-lithium ion iphuma ngexesha lokukhutshwa, izinto eziphathekayo zigcina ingqibelelo yayo yesakhiwo ngokuphawulekayo. Oku kuchasa kabukhali kunye ne-cobalt{2}esekelwe kwi-cathodes, ethi itshintshe umthamo obalulekileyo onokubeka esichengeni ulwakhiwo lweeseli ekuhambeni kwexesha.
Ngexesha lokusebenza, iibhetri ze-LFP zigcina amandla ombane angama-3.2V ngeseli nganye, xa kuthelekiswa ne-3.7V ye-nickel{2}}esekelwe kwi-chemistries. Ngelixa lo mbane usezantsi uthetha iiseli ezine ze-LFP zinokuthatha indawo ye-lead ezintandathu{4}}iiseli zeasidi kwinkqubo ye-12V, ikwanegalelo kuxinano lwamandla olusezantsi oluchaza le chemistry. Ibhondi yephosphate (P{7}}O) kwi-LFP yomelele kakhulu kuneentsimbi{8}}ibhondi zeoksijini kwezinye iikhemistri, eziguqulela ngokuthe ngqo ukuzinza kwe-thermal.
Izinto ezilungileyo eziphambili zeLFP Technology
Iprofayile yoKhuseleko ekhethekileyo
Iibhetri ze-LFP zibonisa uzinzo olumangalisayo lwe-thermal, kunye nokubola okwenzeka malunga ne-270℃xa kuthelekiswa ne-210℃yeebhetri ze-NMC. Uphando lubonisa ukubaleka kwe-thermal yi-80% ngaphantsi kwe-chemistry ye-LFP. Xa ziphantsi kokufudumala kwangaphandle, iiseli ze-LFP zihlala zizinzile ukuya kwi-230 degree, ngelixa iiseli ze-NMC zingazinzi kwi-degree ye-160 kuphela. Nangexesha lokungaphumeleli kwentlekele, iibhetri ze-LFP zifikelela kumaqondo obushushu aphezulu angama-620 xa kuthelekiswa ne-800 yeeseli ze-NMC.
Olu ncedo lokhuseleko luvela kuzinzo lwe-iron phosphate. Ngokungafaniyo ne-cobalt okanye i-nickel-esekelwe kwi-cathodes, i-LFP ayikhuphi ioksijini ngexesha lokusilela, isusa umthombo wepetroli ogcina ukubaleka kwe-thermal kwezinye iikhemistri. Ukuxhathisa kwesixhobo sokubola kwe-thermal kwenza kube nzima kakhulu ukuqalisa ukusabela okuyingozi, naphantsi kweemeko zokuxhatshazwa.
Ubomi Obongezelelweyo
Iibhetri ze-LFP zikholisa ukuzisa i-2,000 ukuya ku-5,000 intlawulo epheleleyo{4}}imijikelo yokukhupha phambi kokuba ithotywe ukuya kwi-80% yomthamo wokuqala. -iiseli ezikumgangatho ophezulu zingadlula 6,000 imijikelo phantsi kweemeko ezifanelekileyo. Oku kubonisa uphuculo olumandla ngaphezulu kweebhetri ze-NMC, ezilawula i-1,000 ukuya kwi-1,500 yeebhayisikile, kwaye ikhuphe ngokupheleleyo iibhetri zeasidi ezinokufikelela kuma-300 ukuya kuma-500 imijikelo.
Uzinzo lwesakhiwo se-LFP ngexesha lokujikeleza kwe-lithiation kunye ne-delithiation ichaza obu bude obude. Xa ihlawulwe ngokupheleleyo kwaye ikhutshwe ngokupheleleyo, i-LFP igcina izakhiwo ze-crystalline ezifanayo, ukuphepha ukuxinzezeleka komatshini okuphazamisa ezinye iikhemistri. Ibhanki yebhetri ye-10kWh ye-LFP esetyenziswa yonke imihla inokuhlala iminyaka eyi-12 ukuya kweli-15, xa kuthelekiswa neminyaka emi-6 ukuya kwe-8 kwiinkqubo ezilinganayo ze-NMC.
Ukusebenza kweendleko
Iibhetri ze-LFP zisebenzisa imathiriyeli eninzi-intsimbi yeyona nto yesine ixhaphakileyo kumhlaba, kwaye iiphosphates zifumaneka lula. Oku kuphelisa ukuxhomekeka kwizinto ezinqabileyo nezixabisa kakhulu njenge-cobalt kunye ne-nickel. Ukusukela ngo-2024, iipakethi zebhetri ze-LFP zibiza malunga ne-20% ngaphantsi kwe-kWh nganye kunezinye iindlela ze-NMC, kunye noqikelelo olumalunga ne-55 ye-€ ($64) nge-kWh{7}}yemveliso ephezulu yevolumu.
Inzuzo yeendleko idlulela ngaphaya kwexabiso lokuqala lokuthenga. Xa iindleko zomjikelo wobomi zibaliwe-ifactoring kubude obuyi-3x ubude kunye neemfuneko zogcino oluncinci{3}}Iibhetri ze-LFP zinikezela ngexabiso elingcono kakhulu. Ukungabikho kwe-cobalt kukwasusa iinkxalabo ezisesikweni malunga nezenzo zemigodi kunye neengxaki zekhonkco lokubonelela ezithwaxa i-nickel{5}}echemistries ezityebileyo.
UkuTshaja ngokukhawuleza ukukwazi ukuTshaja
Ngaphandle koxinano lwamandla aphantsi, iibhetri ze-LFP zixhasa amaxabiso okuhlawula ngokukhawuleza. Ukuphunyezwa kukaTesla kweeseli ze-BYD LFP kwiimoto zeModel Y zifikelela kwi-10% ukuya kwi-80% ukutshaja malunga nemizuzu engama-20 kunye ne-preconditioning efanelekileyo yebhetri, idlula iinkqubo ezininzi ze-NMC. Ubume bekristale obuqinileyo bunyamezela amaxabiso aphezulu entlawulo ngaphandle kokuthotywa okukhawulezileyo okubonwa kwezinye iikhemistri.
Iiseli ze-LFP zigcina amandla okutshaja ixesha elide ngexesha lokutshaja xa kuthelekiswa ne-nickel-esekelwe kwiibhetri. Ngelixa zombini zinokubonelela ngexabiso elifanayo eliphezulu lentlawulo, i-LFP igcina loo maxabiso ngemeko ebanzi-ye{3}}yefestile yentlawulo, okukhokelela kumaxesha okwenene{4}ehlabathi okutshaja kwiiseshini zentlawulo eqhelekileyo.
Unyino kunye noRhwebo{0}}nokupheliswa
Uxinzelelo lwaMandla asezantsi
