Izinto eziluncedo kwiibhetri ze-lithium iron phosphate
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 okufana ne-lithium cobalt oxide okanye yenze izinto ezinamandla ze-oxidizing, ngoko inokhuseleko oluhle.Ingxelo yabonisa ukuba ekusebenzeni kwangempela, inani elincinci leesampuli zafunyanwa zivutha kwi-acupuncture okanye iimvavanyo ezifutshane zesekethe, kodwa kwakungekho kuqhuma.ugqabhuko-dubulo.Nangona kunjalo, ukhuseleko lwayo lwe-overcharge luphuculwe kakhulu xa kuthelekiswa nolwelo oluqhelekileyo lwe-electrolyte lithium cobalt oxide iibhetri.
2. Ukuphuculwa kwexesha lokuphila
Ibhetri ye-lithium ye-iron phosphate ibhekisela kwibhetri ye-lithium ion esebenzisa i-lithium iron phosphate njengento efanelekileyo ye-electrode.
Ubomi bomjikelezo wobomi obude beebhetri ze-lead-acid malunga namaxesha angama-300, kwaye ubuninzi bumaxesha angama-500, ngelixa ubomi bomjikelezo we-lithium iron phosphate amandla ebhetri bunokufikelela ngaphezu kwamaxesha e-2,000, kunye nokutshaja okusemgangathweni (izinga le-5-yure) ukusetyenziswa kunokufikelela amaxesha angama-2,000.Ibhetri ye-lead-acid yomgangatho ofanayo "unyaka omtsha wesiqingatha, umnyaka wesiqingatha esidala, kunye nokugcinwa kunye nokugcinwa kwesiqingatha sonyaka", okuyi-1 ~ 1.5 iminyaka kakhulu, kwaye ibhetri ye-lithium iron phosphate isetyenziswa phantsi kweemeko ezifanayo, ubomi bethiyori buya kufikelela kwi-7 ~ 8 iminyaka.Uqwalaselo olubanzi, umlinganiselo wexabiso lokusebenza ngokwethiyori ungaphezulu kwamaxesha ama-4 kuneebhetri ze-lead-asidi.Ukukhutshwa okuphezulu kwangoku kunokukhawuleza ukuhlawulisa kunye nokukhupha i-2C ephezulu yangoku.Ngaphantsi kweshaja ekhethekileyo, ibhetri inokuhlawulwa ngokupheleleyo ngaphakathi kwemizuzu engama-40 ye-1.5C ukutshaja, kwaye isiqalo sangoku sinokufikelela kwi-2C, kodwa iibhetri ze-lead-acid azinayo le ntsebenzo.
3. Ukusebenza kakuhle kobushushu obuphezulu
Incopho yokufudumala yombane ye-lithium iron phosphate inokufikelela 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-peak yokufudumala yombane ye-lithium iron phosphate inokufikelela kwi-350 ℃-500 ℃, ngelixa i-lithium manganate kunye ne-lithium cobaltate ijikeleze i-200 ℃ kuphela.
4. Umthamo omkhulu
Iibhetri zihlala zisebenza phantsi kweemeko zokuhlawulwa ngokupheleleyo, kwaye umthamo uya kuhla ngokukhawuleza ngaphantsi komthamo olinganisiweyo.Le nto ibizwa ngokuba yimemori effect.Njenge-nickel-metal hydride kunye neebhetri ze-nickel-cadmium, kukho imemori, kodwa iibhetri ze-lithium iron phosphate azinayo le nto.Nokuba ibhetri ikwimeko enjani, inokusetyenziswa nangaliphi na ixesha ngaphandle kokuyikhupha phambi kokutshaja.
5. Ubunzima obulula
Umthamo webhetri ye-lithium yentsimbi ye-phosphate eneenkcukacha ezifanayo kunye nomthamo ngu-2/3 wevolumu yebhetri ye-lead-acid, kunye nobunzima be-1/3 yebhetri ye-lead-acid.
6. Ukhuseleko lokusingqongileyo
Iibhetri zeLithium iron phosphate ngokubanzi zithathwa njengezingenazo naziphi na iintsimbi ezinzima kunye neentsimbi ezinqabileyo (ibhetri yenickel-metal hydride ifuna iintsimbi ezinqabileyo), ezingenayo ityhefu (i-SGS eqinisekisiweyo), engangcolisi, ithobela imimiselo ye-RoHS yaseYurophu, kwaye iyinto epheleleyo. isatifikethi sebhetri eluhlaza.Ke ngoko, isizathu sokuba ibhetri ye-lithium ithandwa lishishini ikakhulu ngenxa yokuqwalaselwa kokusingqongileyo.Ngoko ke, ibhetri ifakwe kwi-"863" isicwangciso sesizwe sophuhliso lobuchwepheshe obuphezulu ngexesha le "Iplani yeShumi yeMinyaka emihlanu", kwaye ibe yiprojekthi ephambili exhaswayo kwaye ikhuthazwa ngurhulumente.Ngokungena kweTshayina kwi-WTO, umthamo wokuthumela ngaphandle kweebhayisikile zombane zaseTshayina uza kunyuka ngokukhawuleza, kwaye iibhayisekile zombane ezingena eYurophu nase-United States kuye kwafuneka ukuba zixhotyiswe ngeebhetri ezingangcolisi.
Nangona kunjalo, ezinye iingcali zathi ungcoliseko lwemekobume olubangelwa ziibhetri ze-lead-acid ubukhulu becala lwenzeka kwinkqubo yokuvelisa engekho mgangathweni kunye nenkqubo yokuhlaziya amashishini.Ngendlela efanayo, iibhetri ze-lithium ziyinxalenye yeshishini elitsha lamandla, kodwa ayikwazi ukuphepha ingxaki yokungcola kwensimbi enzima.Ilothe, i-arsenic, i-cadmium, i-mercury, i-chromium, njl.Ibhetri ngokwayo iyinto yeekhemikhali, ngoko inokubangela iindidi ezimbini zongcoliseko: enye yinkqubo yongcoliseko lwenkunkuma kwiprojekthi yokuvelisa;enye kukungcoliseka kwebhetri emva kokuchithwa.
Iibhetri ze-lithium iron phosphate nazo zineziphene zazo: umzekelo, ukusebenza kweqondo lobushushu eliphantsi limbi, ukuxinana kwempompo yezixhobo ze-electrode ezilungileyo kuphantsi, kwaye umthamo webhetri ye-lithium iron phosphate enomthamo olinganayo mkhulu kuneebhetri ze-lithium ion ezifana ne-lithium. i-cobalt oxide, ngoko ayinayo inzuzo kwiibhetri ezincinci.Xa zisetyenziswa kwiibhetri zamandla, iibhetri ze-lithium iron phosphate, njengezinye iibhetri, kufuneka zijongane nengxaki yokungaguquguquki kwebhetri.
