Inzuzo

1. Ukwenziwa ngcono kokusebenza kokuphepha
Ibhondi ye-PO ku-lithium iron phosphate crystal izinzile futhi kunzima ukubola.Ngisho nokushisa okuphezulu noma ukukhokhiswa ngokweqile, ngeke kugoqe futhi kukhiqize ukushisa noma ukwakha izinto eziqinile ze-oxidizing esakhiweni esifanayo ne-lithium cobalt oxide, ngakho-ke inokuphepha okuhle.Umbiko wabonisa ukuthi ekusebenzeni kwangempela, ingxenye encane yamasampula yatholakala ishisa ekuhlolweni kwe-acupuncture noma i-short-circuit, kodwa akukho kuqhuma okwenzeka.Esivivinyweni sokushajwa kwe-overcharge, kwasetshenziswa ukushajwa kwamandla kagesi aphezulu okwakuphindwe izikhathi ezimbalwa kunomthamo 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 phosphateibhekisela kubhethri ye-lithium ion esebenzisa i-lithium iron phosphate njengento enhle ye-electrode.
Impilo yomjikelezo webhethri le-lead-acid yempilo ende cishe izikhathi ezingama-300, futhi eliphakeme kakhulu izikhathi ezingama-500.Ibhethri ye-lithium iron phosphate amandla e-lithium inokuphila komjikelezo izikhathi ezingaphezu kuka-2000, futhi ukushaja okujwayelekile (isilinganiso samahora angu-5) ukusetshenziswa kungafinyelela izikhathi ezingu-2000.Amabhethri e-lead-acid ekhwalithi efanayo masha isigamu sonyaka, amadala isigamu sonyaka, futhi ukugcinwa nokugcinwa uhhafu wonyaka, okungenani 1 kuya 1.5 iminyaka, kuyilapho lithium iron phosphate amabhethri asetshenziswa ngaphansi kwezimo ezifanayo bayoba impilo yethiyori yeminyaka eyi-7 kuye kweyisi-8.Uma kucatshangelwa kabanzi, isilinganiso senani lokusebenza ngokombono singaphezu kokuphindwe ka-4 kunesamabhethri e-lead-asidi.Ukukhishwa okuphezulu kwamanje kungashaja ngokushesha futhi kukhiphe i-2C yamanje ephezulu.Ngeshaja ezinikele, ibhethri lingashajwa ngokugcwele phakathi nemizuzu engama-40 yokushajwa okungu-1.5C.Ukuqala kwamanje kungafinyelela ku-2C, kodwa amabhethri e-lead-acid awanakho ukusebenza okunjalo.
3. Ukusebenza okuhle kwezinga lokushisa eliphezulu
Inani eliphakeme lokushisisa ngogesi kwe-lithium iron phosphate lingafinyelela ku-350℃-500 ℃, kuyilapho i-lithium manganate ne-lithium cobaltate izungeze u-200℃ kuphela.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
∩Lapho ibhethri elishajekayo lihlala lishajwe ngokugcwele futhi lingashajwa, umthamo uzokwehla ngokushesha ngaphansi kwevelu yomthamo olinganiselwe.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 ngokushesha nje lapho selishajwe.
6, isisindo esilula
Ivolumu yebhethri ye-lithium iron phosphate yokucaciswa okufanayo kanye 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), okungewona ubuthi (isitifiketi se-SGS), okungangcolisi, ngokuhambisana nemithetho ye-European RoHS, kanye nokuphelele. isitifiketi sebhethri eliluhlaza.Ngakho-ke, isizathu sokuthi kungani amabhethri e-lithium-ion ethandwa yimboni kubalulekile ngenxa yokucatshangelwa kokuvikelwa kwemvelo.Ngakho-ke, ibhethri selifakiwe kuHlelo Lokuthuthukiswa Kobuchwepheshe Bezinga Likazwelonke le-863 phakathi noHlelo Lweminyaka Eyishumi Lweminyaka Emihlanu futhi selube yiphrojekthi esemqoka kazwelonke yokweseka kanye nesikhuthazo.Ngokungena kwezwe lami ku-WTO, ukuthunyelwa kwezwe lami kwamabhayisikili kagesi kuzokwanda ngokushesha, futhi amabhayisikili kagesi angena e-Europe nase-United States kudingeke ukuthi afakwe amabhethri angangcoli.
Nokho, abanye ochwepheshe bathi ukungcoliswa kwemvelo okubangelwa amabhethri aneasidi yomthofu kwenzeka ikakhulukazi enqubweni yokukhiqiza engavamile yenkampani nenqubo yokugaywa kabusha.Ngendlela efanayo, amabhethri e-lithium-ion ayingxenye yemboni entsha yamandla, kodwa awakwazi ukuvimbela ukungcoliswa kwensimbi esindayo.Umthofu, i-arsenic, i-cadmium, i-mercury, i-chromium, njll. ekucutshungulweni kwezinto zensimbi kungase kukhishwe uthuli namanzi.Ibhethri ngokwalo liwuhlobo lwamakhemikhali, ngakho-ke kungase kube nezinhlobo 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 kampompi okuphansi kwezinto ze-cathode, kanye nevolumu yamabhethri e-lithium iron phosphate anamandla alinganayo makhulu kunamabhethri e-lithium-ion afana ne-lithium cobalt oxide, ngakho-ke abanazo izinzuzo kumabhethri amancane.Uma isetshenziswa emabhethri e-lithium amandla, amabhethri e-lithium iron phosphate ayafana namanye amabhethri, futhi kufanele abhekane nezinkinga zokungaguquguquki kwebhethri.
