Liyini Ibhethri Le-LiFePO4?
Ibhethri ye-LiFePO4 iwuhlobo lwebhethri ye-lithium-ion esebenzisa i-lithium iron phosphate (LiFePO4) ezintweni zayo ze-electrode ezinhle.Leli bhethri lidume ngokuphepha kwalo okuphezulu nokuzinza, ukumelana nezinga lokushisa eliphezulu, nokusebenza kahle komjikelezo.
Ingakanani impilo yephakethe lebhethri le-LiFePO4?
Amabhethri e-lead-acid ngokuvamile anempilo yomjikelezo cishe imijikelezo engama-300, enemijikelezo engu-500 ephezulu.Ngokuphambene, amabhethri wamandla we-LiFePO4 anempilo yomjikelezo engaphezu kwemijikelezo engu-2000.Amabhethri aneasidi yomthofu ngokuvamile ahlala cishe unyaka ongu-1 kuya ku-1.5, achazwa ngokuthi “masha athatha ingxenye yonyaka, amadala ayingxenye yonyaka, futhi anakekele enye ingxenye yonyaka.”Ngaphansi kwezimo ezifanayo, iphakethe lebhethri le-LiFePO4 linokuphila okucatshangelwayo okuyiminyaka eyi-7 kuye kweyi-8.
Amaphakethe ebhethri e-LiFePO4 ngokuvamile ahlala cishe iminyaka eyi-8;nokho, ezindaweni ezifudumele, isikhathi sabo sokuphila singadlulela eminyakeni eyi-8.Impilo yethiyori yephakethe yebhethri ye-LiFePO4 idlula imijikelezo yokushaja engu-2,000, okusho ukuthi noma ngokushajwa kwansuku zonke, ingahlala ngaphezu kweminyaka emihlanu.Ngokusetshenziswa kwasekhaya okuvamile, lapho ukushaja kwenzeka njalo ezinsukwini ezintathu, kungathatha iminyaka eyisishiyagalombili.Ngenxa yokungasebenzi kahle kwezinga lokushisa eliphansi, amabhethri e-LiFePO4 avamise ukuba nesikhathi eside sokuphila ezindaweni ezifudumele.
Impilo yesevisi yephakethe yebhethri ye-LiFePO4 ingafinyelela cishe imijikelezo engu-5,000, kodwa kubalulekile ukuqaphela ukuthi ibhethri ngalinye linenani elicacisiwe lokushaja kanye nemijikelezo yokukhipha (isb, imijikelezo eyi-1,000).Uma le nombolo yeqiwe, ukusebenza kwebhethri kuzokwehla.Ukukhipha okuphelele kuthinta kakhulu impilo yebhethri, ngakho-ke kubalulekile ukugwema ukuchithwa ngokweqile.
Izinzuzo zamaphakethe ebhethri e-LiFePO4 uma kuqhathaniswa namabhethri ane-acid eholayo:
Amandla Aphezulu: Amaseli e-LiFePO4 angasukela ku-5Ah ukuya ku-1000Ah (1Ah = 1000mAh), kuyilapho amabhethri e-lead-asidi ngokuvamile asuka ku-100Ah kuya ku-150Ah ngeseli engu-2V ngayinye, ngokuhlukahluka okulinganiselwe.
Isisindo Esilula: Iphakethe lebhethri le-LiFePO4 lomthamo ofanayo licishe libe izingxenye ezimbili kwezintathu zevolumu kanye nengxenye eyodwa kwezintathu yesisindo sebhethri le-asidi yomthofu.
Amandla Okushaja Ngokushesha Aqinile: Ukuqala kwamanje kwephakethe lebhethri le-LiFePO4 lingafinyelela ku-2C, livumela ukushajwa kwezinga eliphezulu.Ngokuphambene, amabhethri e-lead-acid ngokuvamile adinga amandla akhona phakathi kuka-0.1C no-0.2C, okwenza ukushaja okusheshayo kube nzima.
Ukuvikelwa Kwemvelo: Amabhethri aneasidi yomthofu aqukethe amanani abalulekile omthofu, okhiqiza udoti oyingozi.Amaphakethe ebhethri e-LiFePO4, ngakolunye uhlangothi, awanazo izinsimbi ezinzima futhi awabangeli ukungcola ngesikhathi sokukhiqiza nokusetshenziswa.
Izindleko Ezivamile: Nakuba amabhethri e-lead-asidi ekuqaleni eshibhile ngenxa yezindleko zawo zempahla, amabhethri e-LiFePO4 abonakala eyonga kakhulu ngokuhamba kwesikhathi, uma kucatshangelwa impilo yawo yesevisi ende kanye nezidingo eziphansi zokunakekela.Izinhlelo zokusebenza ezingokoqobo zibonisa ukuthi ukusebenza kahle kwezindleko zamabhethri e-LiFePO4 kungaphezu kokuphindwe kane kunamabhethri e-lead-acid.
