Inzuzo
1. Ukuphuculwa kokusebenza kokhuseleko
I-PO bond kwi-lithium iron phosphate crystal izinzile kwaye inzima ukubola.Nangona kubushushu obuphezulu okanye ukugqithisa, akuyi kudilika kwaye kuvelise ukushisa okanye ukwenza izinto ezinamandla ze-oxidizing kwisakhiwo esifanayo ne-lithium cobalt oxide, ngoko inokhuseleko oluhle.Ingxelo yabonisa ukuba ekusebenzeni kwangempela, inxalenye encinci yeesampuli zafunyanwa ukuba zitshise kwi-acupuncture okanye iimvavanyo ze-short-circuit, kodwa akukho kuqhuma kwenzeka.Kuvavanyo lokutshaja okugqithisileyo, ukutshajiswa kwamandla ombane aphezulu okuphindwe kaninzi ngaphezulu kombane ozikhuphayo osetyenzisiweyo, kwaye kwafunyaniswa ukuba kusekho i-Explosion phenomenon.Nangona kunjalo, ukhuseleko lwayo lwe-overcharge luphuculwe kakhulu xa kuthelekiswa nolwelo oluqhelekileyo lwe-electrolyte lithium cobalt oxide iibhetri.
2. Ukuphuculwa kobude bobomi
Lithium iron phosphate ibhetriibhekisela kwibhetri ye-lithium ion usebenzisa i-lithium iron phosphate njengento efanelekileyo ye-electrode.
Ubomi bomjikelezo webhetri ye-lead-acid yexesha elide malunga namaxesha angama-300, kwaye iphakamileyo ngamaxesha angama-500.I-lithium iron phosphate amandla ibhetri ye-lithium inobomi bomjikelezo wamaxesha angaphezu kwama-2000, kwaye umrhumo oqhelekileyo (izinga leeyure ezi-5) ukusetyenziswa kunokufikelela kumaxesha angama-2000.Iibhetri ze-lead-asidi ezisemgangathweni ofanayo zintsha kwisiqingatha sonyaka, ubudala kwisiqingatha sonyaka, kunye nokugcinwa nokugcinwa kwesiqingatha sonyaka, ubukhulu be-1 ukuya kwi-1.5 yeminyaka, ngelixa iibhetri ze-lithium iron phosphate ezisetyenziswa phantsi kweemeko ezifanayo ziya kuba nazo. ubomi ithiyori 7 ukuya 8 iminyaka.Ukuqwalasela ngokubanzi, umlinganiselo wexabiso lokusebenza ngokwethiyori ungaphezulu kwamaxesha ama-4 kuneebhetri ze-lead-asidi.Ukukhutshwa okuphezulu kwangoku kunokukhawuleza ukuhlawulisa kunye nokukhupha i-2C ephezulu yangoku.Ngetshaja ezinikeleyo, ibhetri inokutshajwa ngokupheleleyo kwimizuzu engama-40 yokutshaja kwe-1.5C.Isiqalo sangoku sinokufikelela kwi-2C, kodwa iibhetri ze-lead-acid azinayo ukusebenza okunjalo.
3. Ukusebenza kakuhle kobushushu obuphezulu
Ixabiso eliphezulu le-lithium iron phosphate ukufudumeza kombane linokufikelela kwi-350 ℃-500 ℃, ngelixa i-lithium manganate kunye ne-lithium cobaltate zijikeleze i-200 ℃ kuphela.Uluhlu olubanzi lobushushu bokusebenza (-20C-75C), kunye nokumelana nobushushu obuphezulu, i-lithium iron phosphate electric heat heat inokufikelela kwi-350℃-500 ℃, ngelixa i-lithium manganate kunye ne-lithium cobaltate zijikeleze i-200 ℃ kuphela.
4. Umthamo omkhulu
∩Xa ibhetri egcwalisekayo isoloko igcwaliswe ngokupheleleyo kwaye ingakhutshwa, umthamo uya kuwela ngokukhawuleza ngaphantsi kwexabiso lomthamo olinganisiweyo.Le nto ibizwa ngokuba yinkumbulo yesiphumo.Njenge-nickel-metal hydride kunye neebhetri ze-nickel-cadmium, kukho imemori, kodwa iibhetri ze-lithium iron phosphate azinayo le nto.Nokuba ibhetri ikwimeko enjani, inokutshajwa kwaye isetyenziswe nje ukuba itshajiwe.
6, ubunzima obulula
Umthamo webhetri ye-lithium yentsimbi ye-phosphate yenkcazo efanayo kunye nomthamo ngu-2/3 wevolumu yebhetri ye-lead-acid, kunye nobunzima be-1/3 yebhetri ye-lead-acid.
7. Ukhuseleko lokusingqongileyo
Iibhetri zeLithium iron phosphate ngokubanzi zithathwa njengezingenazo naziphi na iintsimbi ezinzima kunye neentsimbi ezinqabileyo (ibhetri yenickel-hydrogen ifuna isinyithi esinqabileyo), engeyiyo ityhefu (isiqinisekiso se-SGS), engangcolisi, ngokuhambelana nemigaqo ye-RoHS yaseYurophu, kwaye iphelele. isatifikethi sebhetri eluhlaza.Ke ngoko, isizathu sokuba iibhetri ze-lithium-ion zithandwa lishishini libalulekile ngenxa yokuqwalaselwa kokusingqongileyo.Ngoko ke, ibhetri ibandakanyiwe kwiSicwangciso soPhuhliso seSizwe sobuGcisa obuPhezulu beSizwe ngexesha leSicwangciso seMinyaka emiHlanu kwaye iye yaba yiprojekthi yenkxaso nenkuthazo yesizwe engundoqo.Ngokungena kwelizwe lam kwi-WTO, ilizwe lam elithumela iibhayisikile zombane kumazwe angaphandle liza kunyuka ngokukhawuleza, kwaye iibhayisekile zombane ezingena eYurophu nase-United States kuye kwafuneka ukuba zixhotyiswe ngeebhetri ezingangcolisekiyo.
Noko ke, ezinye iingcali zathi ungcoliso lwemekobume olubangelwa ziibhetri ezineasidi yelothe ubukhulu becala lwenzeka kwinkqubo yokuvelisa engaqhelekanga yenkampani kunye nenkqubo yokuhlaziya.Ngendlela efanayo, iibhetri ze-lithium-ion ziyinxalenye yeshishini elitsha lamandla, kodwa azikwazi ukuthintela ukungcoliseka kwesinyithi esinzima.Ilothe, i-arsenic, i-cadmium, i-mercury, i-chromium, njl. njlIbhetri ngokwayo luhlobo lwento yeekhemikhali, ngoko ke kunokubakho iintlobo ezimbini zokungcola: enye kukungcoliseka kwenkqubo yokungcola kubunjineli bemveliso;enye kukungcoliseka kwebhetri emva kokuba ichithwe.
Iibhetri ze-lithium ye-phosphate ye-iron phosphate nazo zineentsilelo zazo: umzekelo, ukusebenza kakubi kobushushu obuphantsi, ukuxinana kwempompo ye-cathode ephantsi, kunye nomthamo webhetri ye-lithium ye-iron phosphate enomthamo olinganayo mkhulu kuneebhetri ze-lithium-ion ezifana ne-lithium cobalt oxide. ngoko abanayo inzuzo kwiibhetri ezincinci.Xa isetyenziswa kumandla ebhetri ye-lithium, iibhetri ze-lithium iron phosphate ziyafana nezinye iibhetri, kwaye kufuneka zijongane neengxaki zokungaguquguquki kwebhetri.
