Ukukhuluma mayelana nezingxenye ezibalulekile zephakethe lebhethri-iseli yebhethri (1)

Iningi lamabhethri asetshenziswa kuma-PACK ajwayelekile emakethe amabhethri e-lithium iron phosphate.

"Lithium iron phosphate battery", igama eligcwele lithium iron phosphate lithium ion battery, igama lide kakhulu, elibizwa ngokuthi lithium iron phosphate battery.Ngenxa yokuthi ukusebenza kwayo kulungele ukusetshenziswa kwamandla, igama elithi "amandla" lengezwa egameni, okungukuthi, ibhethri yamandla e-lithium iron phosphate.Ibizwa nangokuthi "ibhethri ye-lithium iron (LiFe) amandla".

isimiso sokusebenza

Ibhethri ye-lithium iron phosphate ibhekisela kubhethri ye-lithium ion esebenzisa i-lithium iron phosphate njengento esebenzayo ye-electrode.Izinto ze-cathode zamabhethri e-lithium-ion ikakhulukazi zihlanganisa i-lithium cobalt oxide, i-lithium manganate, i-lithium nickel oxide, izinto ze-ternary, i-lithium iron phosphate, njll. .

ukubaluleka

Emakethe yokuhweba ngensimbi, i-cobalt (Co) iyona ebiza kakhulu, futhi akukho sitoreji esiningi, i-nickel (Ni) ne-manganese (Mn) ishibhile, futhi insimbi (Fe) inesitoreji esiningi.Amanani ezinto ze-cathode nawo ahambisana nalawo alezi zinsimbi.Ngakho-ke, amabhethri e-lithium-ion enziwe ngezinto ze-LiFePO4 cathode kufanele ashibhile.Esinye isici sayo ukuthi ayihambisani nemvelo futhi ayingcolisi.

Njengebhethri elishajekayo, izimfuneko yilezi: umthamo omkhulu, amandla kagesi aphezulu, ukusebenza kahle komjikelezo wokushajwa, ugesi ophumayo ozinzile, ukushajwa okuphezulu kwamanje, ukuqina kwe-electrochemical, nokuphepha okusebenzayo (hhayi ngenxa yokushajwa ngokweqile, ukukhipha ngokweqile kanye nokufushane. isifunda).Ingabangela ukusha noma ukuqhuma ngenxa yokusebenza okungalungile), ububanzi bezinga lokushisa lokusebenza, elingenabo ubuthi noma ubuthi obuncane, futhi akukho ukungcoliswa kwemvelo.Amabhethri e-LiFePO4 asebenzisa i-LiFePO4 njenge-electrode enhle anezidingo zokusebenza ezinhle, ikakhulukazi mayelana nokukhishwa kwesilinganiso esikhulu sokukhipha (5 ~ 10C ukukhishwa), i-voltage yokukhishwa okuzinzile, ukuphepha (okungashisi, okungaqhumi), ukuphila (izikhathi zomjikelezo) ), akukho ukungcoliswa kwemvelo, iyona ehamba phambili, futhi okwamanje iyibhethri lamandla aphumayo lamanje elingcono kakhulu.
