I-LFP vs iibhetri ze-NMC: I-Dive eNzulu yezicelo zokuGcina amandla

Imakethi yokugcina amandla iyanda, iqhutywa yimfuneko yozinzo lwegridi, ukudityaniswa kwamandla ahlaziyekayo, kunye nezisombululo zamandla okugcina. Kwintliziyo yeenkqubo ezininzi zokugcina amandla ebhetri (BESS) ilele iteknoloji ye-lithium-ion, kunye ne-Lithium Iron Phosphate (LFP) kunye ne-Nickel Manganese Cobalt (NMC) zimbini zekhemistri ezibalaseleyo.

Ukukhetha i-chemistry efanelekileyo yebhetri sisigqibo esibalulekileyo kuyo nayiphi na iprojekthi yokugcina amandla, impembelelo yokusebenza, ukhuseleko, ixesha lokuphila kunye neendleko. Ngelixa zombini i-LFP kunye ne-NMC ziye zangqina iirekhodi, iimpawu zazo ezahlukileyo zizenza zilungele usetyenziso olwahlukeneyo ngaphakathi kwendawo enkulu yokugcina amandla.

Eli nqaku lihlalutya uthelekiso olucacileyo lweebhetri ze-LFP kunye ne-NMC, ngokukodwa ekugxininiseni ukufaneleka kwazo kunye nokusebenza kwiinkqubo zokugcina amandla (ESS).

Ukuqonda iSiseko: Yintoni iibhetri ze-LFP kunye ne-NMC?

Bobabini i-LFP kunye ne-NMC ziintlobo zeebhetri ze-lithium-ion, oku kuthetha ukuba zigcina kwaye zikhulule amandla ngokuhamba kwe-lithium ion phakathi kwe-electrode enhle (i-cathode) kunye ne-electrode negative (anode). Umahluko ophambili ulele kwizinto ze-cathode.

I-LFP (i-Lithium Iron Phosphate): Isebenzisa i-LiFePO4 njengesixhobo se-cathode. Esi sakhiwo saziwa ngozinzo lwaso olukhethekileyo.
I-NMC (Nickel Manganese Cobalt): Isebenzisa umxube wenickel, manganese, kunye necobalt oxides ngokwemilinganiselo eyahlukeneyo (umz., NMC 111, 532, 622, 811) njengecathode. Ngokuhlengahlengisa umlinganiselo, abavelisi banokulungiselela iipropathi ezahlukeneyo ezifana nokuxinana kwamandla okanye ubomi bomjikelezo.

Ngoku, masizithelekise ngokusekwe kwizinto ezibaluleke kakhulu kwizicelo zokugcina amandla.

Izalathisi zokuSebenza eziphambili: LFP vs NMC kwi-ESS

Xa uvavanya iibhetri ze-BESS, iiparitha ezininzi zobugcisa zithatha indawo esembindini.

Ukhuseleko

I-LFP: Ngokuqhelekileyo ithathwa njengekhuselekile ngenxa yesakhiwo sayo se-olivine esizinzile. Ibhondi ye-PO kwi-LiFePO4 yomelele kuneebhondi ze-metal-oxide kwi-NMC, iyenza ukuba ingabikho lula ekubalekeni kwe-thermal naphantsi kweemeko ezinzima njengokutshaja kakhulu okanye umonakalo womzimba. Olu khuseleko lwendalo luyinzuzo enkulu kwizistim ezinkulu, ezimileyo zokugcina amandla apho ukhuseleko lubaluleke kakhulu.

I-NMC: Ngelixa uphuculo olubalulekileyo lwenziwe, iibhetri ze-NMC, ingakumbi iintlobo ze-nickel eziphezulu, azihlali kakuhle ngokwe-LFP kwaye zisesichengeni sokubaleka kwe-thermal ukuba azilawulwa kakuhle. IiNkqubo zoLawulo lweBatri ekwiNgxaki (i-BMS) kunye nolawulo lobushushu zibalulekile ekuqinisekiseni ukhuseleko lwe-NMC.

[Phawula i-ESS]:Kugcino olumileyo, iprofayile yokhuseleko ephezulu ye-LFP lulutho olubalulekileyo, olunokubakho ukwenza lula uyilo lwenkqubo kunye nokunciphisa iindleko zeziseko ezingundoqo zokhuseleko xa kuthelekiswa ne-NMC.

Ubomi bomjikelo

I-LFP: Ngokuqhelekileyo inika ubomi bomjikelo obude xa kuthelekiswa namachiza amaninzi e-NMC. Iibhetri ze-LFP zihlala zimelana namawaka emijikelo yokukhupha intlawulo (umzekelo, imijikelo eyi-6,000+ kwi-80% DOD) ngokuthotywa okuncinci. Oku kuqina kubangelwa yi-crystal structure ezinzileyo kunye noxinzelelo oluncinci lomatshini ngexesha lokuhamba ngebhayisikili.

I-NMC: Ubomi bomjikelo buyahluka kakhulu ngokuxhomekeke kulwakhiwo oluthile lwe-NMC (umzekelo, umxholo we-nickel osezantsi njenge-NMC 111 unokuba nobomi obude kune-nickel ephezulu ye-NMC 811). Ngelixa uqulunqo lwe-NMC luphumeza ubomi bomjikelo obulungileyo, i-LFP ibamba ngokubanzi udini lwezicelo ezifuna ukukhwela ibhayisekile rhoqo kwiminyaka emininzi, into eqhelekileyo kugcino lwegridi kunye nolawulo lwamaza.

[Phawula i-ESS]:Ubomi bomjikelo omde buguqulela ngokuthe ngqo kwixesha elide lokusebenza kwi-ESS, ukunciphisa iindleko ezipheleleyo zobunini ngexesha leprojekthi. Unyamezelo lwe-LFP yeyona nto iphambili ekukhuleni kwayo ekukhuleni kogcino oluluncedo.

Uxinzelelo lwamandla (Wh/kg & Wh/L)

I-LFP: Inoxinano lwamandla olusezantsi xa kuthelekiswa nokwenziwa kwe-NMC ezininzi. Oku kuthetha ukuba ibhetri ye-LFP iya kuba nzima kwaye ibe nkulu kunebhetri ye-NMC yomthamo wamandla ofanayo.

I-NMC: Inikezela ngamandla oxinaniso lwamandla, ngakumbi iintlobo zenickel eziphezulu (njenge-NMC 811). Olu phawu luxabiswa kakhulu kwizicelo apho indawo kunye nobunzima bubaluleke kakhulu, njengezithuthi zombane (EVs) ukunyusa uluhlu lokuqhuba.

[Phawula i-ESS]:Ngelixa kubalulekile, uxinaniso lwamandla oluphezulu luhlala lungabalulekanga kangako kugcino lwamandla amileyo (BESS) xa kuthelekiswa nezicelo eziphathwayo (EVs). Kwiiprojekthi ezininzi zegridi-scale okanye ugcino lwentengiso, indawo ekhoyo ingaphantsi komqobo kunesithuthi, okwenza uxinano lwamandla olusezantsi lwe-LFP lube ngaphantsi kokubi. Ukhuseleko kunye nobomi bomjikelo buhlala buba kwindawo yokuqala.

Iindleko

I-LFP: Ngokuqhelekileyo inexabiso eliphantsi lokuvelisa ngenxa yobuninzi kunye neendleko eziphantsi zentsimbi kunye ne-phosphate xa kuthelekiswa ne-nickel kunye ne-cobalt. I-LFP ihlala i-cobalt-free, inqanda ukuguquguquka kwexabiso kunye neenkxalabo zokuziphatha ezihambelana nokumbiwa kwe-cobalt.

I-NMC: Ithanda ukubiza kakhulu, ikakhulu ngenxa yokuguquguquka kwamaxabiso e-nickel ngakumbi i-cobalt. Ixabiso elithile lixhomekeke kumlinganiselo we-Ni:Mn:Co.

[Phawula i-ESS]:Ukusebenza kakuhle kweendleko kubalulekile kugcino lwamandla amakhulu. Iindleko zokuqala eziphantsi ze-LFP kunye nobomi bomjikelo omde negalelo kwiNdleko ekumgangatho ophantsi woGcino (LCOS), iyenza ibe nomtsalane ngokwezoqoqosho kwiiprojekthi ezininzi ze-BESS.

Ubunakho boMbane (inqanaba le-C)

I-LFP: Inokubonelela ngesakhono samandla esilungileyo, esilungele uluhlu lwentlawulo / ukukhutshwa. Ngelixa ingasoloko iyilelwe amazinga e-C aphezulu kakhulu (>5C), i-LFP iqhuba kakuhle kumazinga e-BESS C (umzekelo, i-0.5C ukuya ku-2C) efunekayo kumgangatho womthwalo, ukucheba okuphezulu, kunye nolawulo oluthile lwamaza.

I-NMC: I-nickel ephezulu ye-NMC ngamanye amaxesha inokubonelela ngesakhono samandla esiphezulu kancinci kwizicelo ze-pulse ezibango kakhulu, kodwa i-NMC eqhelekileyo nayo iqhuba kakuhle kwiimfuno zamandla ze-BESS.

[Phawula i-ESS]:Zombini iikhemistri zinokuhlangabezana neemfuno zamandla uninzi lwezicelo ze-BESS. Umlinganiselo othile we-C ofunekayo uxhomekeke kwisicelo (umzekelo, ukulawulwa kwamaza okuphindaphinda kufuna i-C-rate ephezulu kune-peak shaving).

Ubushushu bokusebenza

I-LFP: Ngokuqhelekileyo yenza ngcono kwaye izinzile ngakumbi kwi-thermal kumaqondo obushushu aphezulu xa kuthelekiswa ne-NMC, eyenza lula ulawulo lwe-thermal kwezinye iindawo. Nangona kunjalo, ukusebenza kwe-LFP kunokunciphisa ngokukhawuleza kune-NMC kumaqondo aphantsi kakhulu.

I-NMC: Inikezela ngentsebenzo engcono kumaqondo obushushu aphantsi kakhulu kune-LFP. Nangona kunjalo, kumaqondo obushushu aphezulu, umngcipheko wokubaleka kwe-thermal mkhulu, kufuna iinkqubo zokupholisa ezinamandla.

[Phawula i-ESS]:Uluhlu lweqondo lokushisa lokusingqongileyo lubalulekile. Zombini iikhemistri zifuna iinkqubo ezifanelekileyo zolawulo lwe-thermal (ukufudumeza kunye nokupholisa) ukugcina ukusebenza kakuhle kunye nobomi, kodwa iimfuno ezithile zinokwahluka.
