Isitoreji samandla sisebenzisa iphakethe lebhethri le-lithium iron phosphate liphephile noma cha?Uma kuziwa kumabhethri e-lithium iron phosphate, sizoqale sikhathazeke ngokuphepha kwayo, kulandele ukusetshenziswa kwayo kokusebenza.Ekusetshenzisweni okusebenzayo kokugcinwa kwamandla, ukugcinwa kwamandla kudinga ukusebenza okuphezulu kokuphepha, impilo yomjikelezo ophezulu, izindleko eziphansi zamabhethri e-lithium.Ngakho-ke, ibhethri ye-lithium iron phosphate iphephile noma cha?Kuleli phepha, i-XUANLI iphoqa umhleli we-elekthronikhi ukuthi akuhambise ukuze uthole.
E-China, izinqubomgomo zisanda kwethulwa ukukhuthaza nokulawula ukuthuthukiswa kokugcinwa kwamandla kanye nokubeka phambili izidingo zamazinga okuphepha afanelekile.Ukuze kuvinjwe ingozi yomlilo wesitshalo samandla e-electrochemical energy, izidingo ezinemininingwane zibekwe phambili, kuhlanganisa.
(1) isitshalo samandla okugcina amandla e-electrochemical aphakathi nendawo namakhulu akufanele akhethe amabhethri e-lithium e-ternary, amabhethri e-sodium-sulfur, akufanele akhethe ukusetshenziswa kwamabhethri wamandla wesibili;
(2) ukukhethwa kokusetshenziswa kwesibili kwamabhethri wamandla, kufanele kube ukuhlola okungaguquki futhi kuhlanganiswe nedatha yokulandeleka ukuze kuhlolwe ukuphepha;
(3) Igumbi lezinto zebhethri le-lithium-ion kufanele libe uhlelo lwesendlalelo esisodwa, okungcono lisebenzisa uhlobo lwekhabhini elakhiwe ngaphambili.
Kungakhathaliseki ukuthi isistimu yokugcina amandla emhlabeni wonke esebenzisa amabhethri e-lithium e-ternary, noma i-lithium iron phosphate yaseChina eyinhloko, izinhlelo zokugcina amandla kufanele zibuyele ekuphepheni okuyisisekelo kakhulu, isisekelo sentuthuko.
Eminyakeni yamuva, ubuchwepheshe be-lithium iron phosphate buye bavuthwa ngokugcwele, futhi amabhethri e-lithium e-ternary, amabhethri e-lithium iron phosphate awanazo izingozi zokuphepha, eziphakeme kunokuphepha kwamabhethri e-lead-acid.Okulandelayo ukuqhathanisa izakhiwo eziyinhloko ze-lithium iron phosphate materials nezinto ze-ternary.
Njengoba wazi, ibhethri elisetshenziswa endaweni yokugcina amandla lidinga impilo ende, ukuphepha okuphezulu kanye nezindleko eziphansi.Nakuba ukuminyana kwamandla ebhethri ye-lithium iron phosphate iphansi kakhulu, kodwa ukusebenza kwayo okuphezulu kokushisa, into ebaluleke kakhulu ukuzinza okuhle kokushisa ukusebenza okuhle kokuphepha, impilo ende, futhi okwamanje, uma kuqhathaniswa, izindleko zayo ziphansi kune-ternary.
Ngokuphathelene nezinto ezisetshenziswayo ze-ternary, inomthamo omkhulu wegram kanye nesiteji sokukhipha okuphezulu, okusho ukuthi amandla aphezulu aphezulu.Ukusebenza kwayo kokushisa okuphansi kungcono, ukusebenza kokushisa okuphezulu kujwayelekile, ukuzinza kokushisa kujwayelekile, ukusebenza kokuphepha nakho kujwayelekile.
Ngokombono ophelele, kusukela ezidingweni zokugcina amandla okuphepha okuphezulu, impilo ende, izindleko eziphansi, iphakethe lebhethri le-lithium iron phosphate iyisinqumo esingcono kakhulu sezinto zokwakha zokugcina amandla.
Iphakethe lebhethri le-lithium iron phosphate linezinzuzo zokuphepha nokuthembeka, impilo ende yesevisi, indawo encane, ukusebenza okulula nokugcinwa.Umkhiqizo wamukela iseli yebhethri ye-lithium iron phosphate, inqubo yayo yokukhiqiza isebenzisa imishini ezenzakalelayo ngokugcwele, enokuvumelana okungcono komkhiqizo, akukho kuqhuma futhi akukho mlilo, okuyiseli yebhethri ephephe kunazo zonke ebhethri ye-lithium.
Ukushaja nokukhipha yizimo ezimbili eziyisisekelo zokusebenza zamabhethri e-lithium.Lapho ibhethri ye-lithium iron phosphate ishaja futhi ikhipha, ngenxa yokuthi ikhono le-iron ion oxidation lingaqinile, ngeke likhulule umoya-mpilo, kuba nzima ngokwemvelo ukwenzeka ngokusabela kwe-electrolyte redox, okwenza ibhethri ye-lithium iron phosphate ishaje futhi ikhiphe inqubo indawo ephephile.Akukhona lokho kuphela, ibhethri ye-lithium iron phosphate ekukhishweni kwe-multiplier enkulu, ngisho nenqubo yokushaja ngokweqile nokukhipha, kunzima ukwenzeka ekuphenduleni kwe-redox enobudlova.
Ngasikhathi sinye, i-lithium ekushumekeni, i-lattice ishintsha ukuze iseli (iyunithi elincane kakhulu lokubunjwa kwekristalu) ekugcineni linciphe ngosayizi, okuvele kunciphise ukwanda kwevolumu ye-carbon cathode ekuphenduleni, ukushaja nokukhishwa kwebhethri ye-lithium iron phosphate kungagcina ukuqina kwesakhiwo somzimba, kuqede amandla okwanda kwevolumu kanye nokwenzeka kokuqhuma kwebhethri.
Ukuthuthukiswa kobuchwepheshe bebhethri ye-lithium-ion entsha yengqikithi yokuphepha kubalulekile, okuhlobene nokuthuthukiswa kwesikhathi esizayo kwesikali se-lithium yokugcina amandla esikhathi eside.Ukuphepha kwamandla ebhethri ye-lithium iron phosphate ukuphepha okuphezulu, izindleko eziphansi, okusimeme kuwumgomo ovamile wokuthuthukiswa kwamabhizinisi, kodwa futhi imboni yokugcina amandla inesidingo esiphuthumayo sesiqondiso esibalulekile sokuhlasela.
