Izinzuzo zamabhethri e-lithium iron phosphate
1. Ukwenza ngcono ukusebenza kokuphepha
Ibhondi ye-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 uveze ukuthi ekusebenzeni kwangempela, kwatholakala inani elincane lamasampula evutha ekuhlolweni kwe-acupuncture noma i-short-circuit, kodwa akuzange kube khona ukuqhuma.ukuqhuma okwenzekayo.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 esebenzayo ye-electrode.
Impilo yomjikelezo wamabhethri e-lead-acid ephila isikhathi eside cishe izikhathi ezingama-300, futhi umkhawulo uyizikhathi ezingama-500, kuyilapho impilo yomjikelezo wamabhethri wamandla we-lithium iron phosphate ingafinyelela izikhathi ezingaphezu kuka-2,000, kanye nokushaja okujwayelekile (isilinganiso samahora angu-5) ukusetshenziswa kungafinyelela izikhathi ezingu-2,000.Ibhethri le-lead-acid yekhwalithi efanayo "iwunyaka omusha, isigamu sonyaka, nokugcinwa nokugcinwa kwesigamu sonyaka", okuyiminyaka engu-1 ~ 1.5 kakhulu, futhi ibhethri ye-lithium iron phosphate isetshenziswa ngaphansi kwezimo ezifanayo, impilo yethiyori izofinyelela eminyakeni eyi-7 ~ 8.Ukucatshangelwa okuphelele, isilinganiso senani lokusebenza ngokomqondo singaphezu kokuphindwe ka-4 kunesamabhethri e-lead-asidi.Ukukhipha okuphezulu kwamanje kungashaja ngokushesha futhi kukhiphe i-2C yamanje ephezulu.Ngaphansi kweshaja ekhethekile, ibhethri ingashajwa ngokugcwele phakathi kwemizuzu engu-40 yokushajwa okungu-1.5C, futhi imanje eqalayo ingafinyelela ku-2C, kodwa amabhethri e-lead-acid awanakho lokhu kusebenza.
3. Ukusebenza okuhle kwezinga lokushisa eliphezulu
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, ukuphakama kokushisisa kukagesi kwe-lithium iron phosphate kungafinyelela ku-350℃-500 ℃, kanti i-lithium manganate ne-lithium cobaltate icishe ibe ngu-200℃.
4. Umthamo omkhulu
Amabhethri avamise ukusebenza ngaphansi kwesimo sokushajwa ngokugcwele, futhi umthamo uzokwehla ngokushesha ngaphansi komthamo olinganiselwe.Lesi simo sibizwa nge-memory 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, ingasetshenziswa noma nini ngaphandle kokuyikhipha ngaphambi kokushajwa.
5. Isisindo esincane
Ivolumu yebhethri ye-lithium iron phosphate enencazelo efanayo kanye nomthamo ingu-2/3 wevolumu yebhethri le-lead-acid, futhi isisindo siyi-1/3 yebhethri le-lead-acid.
6. Ukuvikelwa kwemvelo
Amabhethri e-lithium iron phosphate ngokuvamile athathwa njengangenazo izinsimbi ezisindayo nezinsimbi ezingavamile (amabhethri e-nickel-metal hydride adinga izinsimbi ezingavamile), angewona ubuthi (aqinisekisiwe we-SGS), angangcolisi, athobela imithetho ye-European RoHS, futhi aphelele. isitifiketi sebhethri eliluhlaza.Ngakho-ke, isizathu sokuthi kungani ibhethri ye-lithium ithandwa yimboni ikakhulukazi ngenxa yokucatshangelwa kokuvikelwa kwemvelo.Ngakho-ke, ibhethri lifakwe kuhlelo lwe-“863″ lukazwelonke lokuthuthukiswa kobuchwepheshe obuphezulu phakathi nesikhathi “soHlelo Lweminyaka Eyishumi Yeminyaka Emihlanu”, futhi seliphenduke iphrojekthi ebalulekile esekelwa futhi ekhuthazwa uhulumeni.Ngokungena kweChina ku-WTO, umthamo wokuthekelisa wamabhayisikili kagesi waseChina uzokhula ngokushesha, futhi amabhayisikili kagesi angena e-Europe nase-United States kudingeke ukuthi afakwe amabhethri angangcolisi.
Nokho, abanye ochwepheshe bathi ukungcoliswa kwemvelo okubangelwa amabhethri aneasidi yomthofu kwenzeka ikakhulukazi enqubweni yokukhiqiza engajwayelekile kanye nenqubo yokugaywa kabusha kwamabhizinisi.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 ngokwalo liyikhemikhali, ngakho lingabangela izinhlobo ezimbili zokungcola: enye inqubo yokungcoliswa kwemfucuza kuphrojekthi yokukhiqiza;enye iwukungcoliswa kwebhethri ngemva kokulahlwa.
Amabhethri e-lithium iron phosphate nawo aneziphambeko zawo: ngokwesibonelo, izinga lokushisa eliphansi liphansi, ukuminyana kompompi wezinto ezisebenza kahle ze-electrode kuphansi, futhi umthamo wamabhethri e-lithium iron phosphate anomthamo olinganayo mkhulu kunebhethri ye-lithium ion njenge-lithium. i-cobalt oxide, ngakho-ke ayinazo izinzuzo kumabhethri amancane.Uma isetshenziswa kumabhethri kagesi, amabhethri e-lithium iron phosphate, njengamanye amabhethri, adinga ukubhekana nenkinga yokungaguquguquki kwebhethri.
