Igama eliphelele lebhethri ye-lithium iron phosphate lithi ibhethri ye-lithium iron phosphate lithium ion, elibhekisela kubhethri ye-lithium ion esebenzisa i-lithium iron phosphate njengento esebenzayo ye-electrode. Kunezinhlobo eziningi zezinto ze-cathode zamabhethri e-lithium-ion, ikakhulukazi i-lithium cobalt oxide, i-lithium manganate, i-lithium nicklate, izinto ze-ternary, i-lithium iron phosphate nokunye. Phakathi kwazo, i-lithium cobalt oxide okwamanje iyimpahla ye-cathode esetshenziswa kumabhethri amaningi e-lithium-ion, kanti ezinye izinto ze-cathode azizange zikhiqizwe ngobuningi emakethe ngenxa yezizathu ezihlukahlukene. I-lithium iron phosphate nayo ingelinye lamabhethri e-lithium-ion. Ngokomthetho wezinto ezibonakalayo, i-lithium iron phosphate iphinde ibe yinqubo yokuhlanganisa/yokuhlukanisa, efana ncamashi ne-lithium cobaltate ne-lithium manganenate.

Amabhethri e-lithium iron phosphate angamabhethri esibili e-lithium-ion. Okunye ukusetshenziswa kwayo okuyinhloko njengebhethri lamandla. Inezinzuzo ezinhle ngaphezu kwamabhethri e-NI-MH ne-Ni-Cd.

Advantage

1. Ukwenza ngcono ukusebenza kokuphepha

Isibopho se-PO ku-lithium iron phosphate crystal izinzile futhi kunzima ukubola. Ngisho nasezingeni eliphezulu lokushisa noma ukushajwa ngokweqile, ngeke liwe futhi likhiqize ukushisa njenge-lithium cobalt oxide noma lenze izinto eziqinile ze-oxidizing, ngakho linokuphepha okuhle. Umbiko wabonisa ukuthi ekusebenzeni kwangempela kokuhlolwa kwe-acupuncture noma isifunda esifushane, ingxenye encane yamasampula yatholakala ishisa, kodwa akukho kuqhuma okwenzeka. Esivivinyweni sokushajwa kwe-overcharge, kwasetshenziswa ukushajwa kwamandla kagesi aphezulu okwakuphindwe izikhathi ezimbalwa kunogesi ozikhiphayo, futhi kwatholakala ukuthi kwakusenento yokuqhuma. Noma kunjalo, ukuphepha kwayo kokushajwa ngokweqile kuye kwaba ngcono kakhulu uma kuqhathaniswa namabhethri e-electrolyte e-lithium cobalt oxide ajwayelekile.

2, ukuthuthukiswa kwesikhathi sokuphila

“Ibhethri ye-lithium iron phosphate” ibhekisela kubhethri ye-lithium ion esebenzisa i-lithium iron phosphate njengento enhle ye-electrode.

Impilo yomjikelezo webhethri ye-lead-acid yempilo ende cishe izikhathi ezingama-300, futhi ephakeme kakhulu izikhathi ezingama-500, kuyilapho ibhethri lamandla e-lithium iron phosphate linokuphila komjikelezo izikhathi ezingaphezu kuka-2000, futhi lingasetshenziswa izikhathi ezingu-2000 ukushaja okujwayelekile (isilinganiso samahora angu-5). Amabhethri e-lead-acid yekhwalithi efanayo “ayisigamu sonyaka esisha, ingxenye yonyaka ubudala, kanye nengxenye yonyaka ukuze alungiswe”, angathatha iminyaka engu-1 kuya ku-1.5. Uma esetshenziswa ngaphansi kwezimo ezifanayo, amabhethri e-lithium iron phosphate anempilo yethiyori yeminyaka eyi-7 kuye kweyi-8. Ukucatshangelwa okuphelele, isilinganiso senani lokusebenza ngokomqondo singaphezu kokuphindwe ka-4 kunesamabhethri e-lead-asidi. Ukukhishwa kwamanje okuphezulu kungashaja ngokushesha futhi kukhiphe i-2C yamanje ephezulu. Ngeshaja ezinikele, ibhethri lingashajwa ngokugcwele phakathi kwemizuzu engu-40 yokushajwa okungu-1.5C, futhi isimanjemanje esiqalayo singafinyelela ku-2C, kodwa amabhethri e-lead-asidi awanakho ukusebenza okunjalo.

I-3, ukusebenza kahle kokushisa okuphezulu

Isiqongo sokushisisa ngogesi se-lithium iron phosphate singafinyelela ku-350 ℃-500 ℃, kanti i-lithium manganate ne-lithium cobaltate icishe ibe ngu-200 ℃. Ibanga lokushisa elibanzi elisebenzayo (-20C-75C), elinokumelana nokushisa okuphezulu, i-lithium iron phosphate electric heat heat ingafinyelela ku-350 ℃-500 ℃, kanti i-lithium manganate ne-lithium cobaltate icishe ibe ngu-200 ℃.

4, umthamo omkhulu

∩Amandla amabhethri aphinde ashajwe azoba ngaphansi ngokushesha kunomthamo olinganiselwe lapho evame ukushajwa ngokugcwele futhi engashajwa. Lesi simo sibizwa ngokuthi inkumbulo effect. Njengamabhethri e-nickel-metal hydride kanye ne-nickel-cadmium, kukhona inkumbulo, kodwa amabhethri e-lithium iron phosphate awanayo le nto. Kungakhathaliseki ukuthi ibhethri likusiphi isimo, lingashajwa futhi lisetshenziswe ngaphandle kokulikhipha kuqala.

6, isisindo esilula

Ivolumu yebhethri ye-lithium iron phosphate yokucaciswa okufanayo nomthamo ngu-2/3 wevolumu yebhethri le-lead-acid, futhi isisindo siyi-1/3 yebhethri le-lead-acid.

7, ukuvikelwa kwemvelo

Amabhethri e-lithium iron phosphate ngokuvamile athathwa njengangenazo izinsimbi ezisindayo nezinsimbi ezingavamile (ibhethri le-nickel-hydrogen lidinga izinsimbi ezingavamile), okungezona ubuthi (okuqinisekisiwe kwe-SGS), okungangcolisi, ngokuhambisana nemithetho ye-European RoHS, kanye nokuluhlaza ngokuphelele. isitifiketi sebhethri. Ngakho-ke, isizathu sokuthi kungani amabhethri e-lithium ethandwa yimboni ikakhulukazi ngenxa yokucatshangelwa kokuvikelwa kwemvelo. Ngakho-ke, ibhethri lifakiwe ohlelweni lwe-“863” lwezwe lokuthuthukiswa kobuchwepheshe obuphezulu phakathi nesikhathi “soHlelo Lweminyaka Eyishumi Yeminyaka Emihlanu” futhi selube yiphrojekthi esemqoka kazwelonke yokweseka kanye nesikhuthazo. Ngokungena kweChina ku-WTO, umthamo wokuthekelisa waseShayina wamabhayisikili kagesi uzokhula ngokushesha, futhi amabhayisikili kagesi angena e-Europe nase-United States kudingeke ukuthi afakwe amabhethri angangcoli.

Kodwa abanye ochwepheshe bathi ukungcoliswa kwemvelo okubangelwa amabhethri aneasidi yomthofu kwenzeka ikakhulukazi enqubweni yokukhiqiza engavamile yenkampani nenqubo yokugaywa kabusha. Ngendlela efanayo, amabhethri e-lithium ayingxenye yemboni entsha yamandla, kodwa ayikwazi ukugwema inkinga yokungcoliswa kwensimbi esindayo. Umthofu, i-arsenic, i-cadmium, i-mercury, i-chromium, njll. ekucutshungulweni kwezinto zensimbi kungase kukhishwe uthuli namanzi. Ibhethri ngokwayo iwuhlobo lwento yamakhemikhali, ngakho-ke kungenzeka ukukhiqiza izinhlobo ezimbili zokungcola: enye iwukungcoliswa kokungcola kwenqubo kubunjiniyela bokukhiqiza; enye iwukungcoliswa kwebhethri ngemva kokuchithwa.

Amabhethri e-lithium iron phosphate nawo anamaphutha awo: ngokwesibonelo, ukusebenza kahle kwezinga lokushisa eliphansi, ukuminyana okuphansi kompompi we-cathode material, kanye nevolumu yebhethri ye-lithium iron phosphate enomthamo olinganayo mkhulu kunebhethri ye-lithium-ion njenge-lithium. i-cobalt oxide, ngakho-ke ayinayo inzuzo kumabhethri amancane. Uma esetshenziswa kumabhethri wamandla, amabhethri e-lithium iron phosphate, njengamanye amabhethri, adinga ukubhekana nezinkinga zokungaguquguquki kwebhethri.
