Ukusebenza kwebhetri ye-Ternary Lithium kunye nebhetri yeLithium yeIron Phosphate kwimithombo yaMandla ephathwayo yangaphandle
Kwimarike yomthombo wamandla ophathwayo wangaphandle, iibhetri zeLithium Iron Phosphate (LiFePO4) kunye neebhetri zeTernary Lithium ziintlobo ezimbini eziphambili zeeseli zebhetri. Zombini iibhetri zeTernary Lithium kunye neebhetri zeLithium Iron Phosphate zibonisa iingenelo ezahlukeneyo kunye nokungonakali ekusebenziseni imithombo yamandla ephathekayo yangaphandle.
Ibhetri yeLithium yeTernary, ekwaziwa ngokuba yiLithium-ion ternary battery, luhlobo lwebhetri ye-lithium-ion equka iLithium Nickel Manganese Cobalt Oxide (NMC) okanye iLithium Nickel Cobalt Aluminium Oxide (NCA). Ngakolunye uhlangothi, iibhetri ze-Lithium Iron Phosphate zenziwe ngokukodwa ngee-electrode ezilungileyo kunye nezingalunganga, izahluli, i-electrolytes, kunye nee-casings zangaphandle. I-electrode efanelekileyo, ekhonza njengeyunithi yokugcina amandla kwiibhetri ze-lithium-ion, iquka izinto ezisebenzayo, i-conductive agents, i-binders, phakathi kwabanye. Kwiibhetri ze-Lithium Iron Phosphate, izinto ezisebenzayo ze-electrode yi-Lithium Iron Phosphate (LiFePO4), eyaziwayo ngokuzinza komjikelo obalaseleyo, ukumelana nobushushu obuphezulu, kunye neempawu zokhuseleko. Ezi zakhiwo zahlukeneyo zikhokelela kwiimpawu zokusebenza ezahlukileyo.
Ukhuseleko: Iibhetri ze-Lithium Iron Phosphate zibonisa ukuzinza okuphezulu kwe-thermal kwaye azifaneli ukutsha okanye ukuqhuma phantsi kweemeko zobushushu obuphezulu. Oku kungenxa yobushushu babo bokubola kwe 800°C, iphezulu kakhulu kune 200°C yeebhetri zeTernary Lithium. Ke, iibhetri zeLithium Iron Phosphate zibambe inzuzo enkulu kukhuseleko.
Nangona kunjalo, oku akuthethi ukuba ukhuseleko oluphantsi kwiibhetri ze-Ternary Lithium. Ngapha koko, ngenkqubela kuyilo lokhuseleko ngaphakathi kwenkqubo yebhetri yamandla kunye nophuculo lwenkqubo eyohlukeneyo efana nokhuseleko lokutshajiswa ngaphezulu, ukhuseleko lokukhupha ngaphezulu, ukhuseleko lobushushu obugqithisileyo, ukhuseleko lwangoku, njl. njl., ukusebenza kokhuseleko lweebhetri zeTernary Lithium zinako. qinisekiswa. Iibhetri zeLithium Iron Phosphate zibonisa ukhuseleko oluphezulu, alufanelwanga kukuqhushumba okanye imililo. Iimvavanyo kunye novavanyo lubonise ukuba ukumelana nobushushu obuphezulu kunye nokuzinza kweekhemikhali zeLithium Iron Phosphate kubangela umngcipheko ophantsi wokubaleka kwe-thermal xa kuthelekiswa neebhetri ze-Ternary Lithium. Ke ngoko, kwiindawo ezirhabaxa zangaphandle, iLithium Iron
Iibhetri zePhosphate zibonelela ngeziqinisekiso zokhuseleko eziphezulu.
Ngaphezu koko, kwizicelo ezisebenzayo, iibhetri ze-Ternary Lithium zinokuxinwa kwamandla aphezulu, zibonelela ngezantya zokutshaja ezikhawulezayo kunye nokuphuma kwamandla anamandla, alungele iimeko ezineemfuno eziphezulu zokunyamezela, njengezithuthi zombane. Okwangoku, iibhetri ze-Lithium Iron Phosphate zifumana izicelo ezibanzi ngakumbi kwindawo yokugcina amandla ngenxa yobomi babo bomjikelezo omde kunye neendleko eziphantsi.
Ubomi beNkonzo: Iibhetri ze-Ternary Lithium zibonisa ukulahlekelwa kwamandla okuzinzile ngaphezu kokusetyenziswa. Ngokukodwa, emva kwemijikelo engaphezu kwe-1000 yokukhupha intlawulo, banokugcina i-80% yokusebenza kwebhetri. Nangona kunjalo, imveliso yabo yamandla kwindawo yobushushu obuphantsi ithande ukungazinzi, igcina malunga ne-80% yomthamo oqhelekileyo ku- -20°C. Oku kuthetha ukuba kwiimeko ezinzima, ezifana nokuhlolwa kwangaphandle kwasebusika okanye imisebenzi yokunyuka, iibhetri ze-Ternary Lithium zisenokunganikeli amandla aneleyo. Iibhetri zeLithium Iron Phosphate, kwelinye icala, zibonisa ukusebenza okuzinzile ngokubhekiselele ekuthotyweni kwebhetri. Nangona emva kwe-3000 + imijikelezo yokukhupha intlawulo, banokugcina i-80% yokusebenza kwebhetri. Ngokuthelekisa, imveliso yabo yamandla ihlala izinzile kwiindawo ezinobushushu obuphantsi, igcina malunga ne-50% yomthamo oqhelekileyo -20°C. Ke ngoko, iibhetri zeLithium Iron Phosphate zifaneleke ngakumbi kwimisebenzi yangaphandle yemihla ngemihla efana nenkampu, ukufota, njl.
Uxinano lwamandla kunye nesantya sokutshaja: Okwangoku, iibhetri zeTernary Lithium ngokubanzi zinoxinano lwamandla aphezulu kuneebhetri zeLithium Iron Phosphate. Ngokwezinye iinkcukacha zovavanyo, iibhetri ze-Ternary Lithium zinokufikelela kubuninzi bamandla obuyi-200Wh/kg, ngelixa iibhetri ze-Lithium Iron Phosphate zihlala zijikeleza malunga ne-150Wh/kg. Oku kuthetha ukuba, phantsi kobunzima obufanayo, iibhetri ze-Ternary Lithium zinokubonelela ngemveliso ephezulu yamandla. Ukujonga isantya sokutshaja, iibhetri zeTernary Lithium zihlala zikhawuleza xa zithelekiswa neebhetri zeLithium Iron Phosphate. Enye idatha yovavanyo ibonisa ukuba iibhetri ze-Ternary Lithium zikulungele ukutshaja ngokukhawuleza kunye nokutshaja ngokukhawuleza, ngelixa iibhetri ze-Lithium Iron Phosphate zibonisa amazinga okutshaja acothayo. Oku kungenxa yokuba iibhetri ze-Ternary Lithium zinezantya zokufuduka ezikhawulezayo ze-ion, ezivumela iinkqubo zokutshaja ngokukhawuleza. "
