Iyini ibhethri le-LiFePO4?
Ibhethri le-LiFePO4 uhlobo lwebhethri le-lithium-ion elisebenzisa i-lithium iron phosphate (LiFePO4) ukuze likhiqize i-electrode yayo enhle. Leli bhethri lidume ngokuphepha kwalo okuphezulu kanye nokuqina, ukumelana namazinga okushisa aphezulu, kanye nokusebenza kahle komjikelezo.
Iyini isikhathi sokuphila sebhethri le-LiFePO4?
Amabhethri e-lead-acid ngokuvamile anempilo yomjikelezo engaba ngu-300 imijikelezo, enemijikelezo engaphezulu kuka-500. Ngokuphambene nalokho, amabhethri kagesi e-LiFePO4 anempilo yomjikelezo edlula imijikelezo engu-2000. Amabhethri e-lead-acid ngokuvamile ahlala cishe unyaka ongu-1 kuya ku-1.5, achazwa ngokuthi “amasha isigamu sonyaka, amadala isigamu sonyaka, kanye nokugcinwa eminye isigamu sonyaka.” Ngaphansi kwezimo ezifanayo, iphakethe lebhethri le-LiFePO4 linokuphila kweminyaka engu-7 kuya ku-8 ngokwethiyori.
Amabhethri e-LiFePO4 avame ukuhlala iminyaka engaba ngu-8; noma kunjalo, ezindaweni ezifudumele, isikhathi sawo sokuphila singadlula iminyaka engu-8. Isikhathi sokuphila esicatshangelwayo sebhethri le-LiFePO4 sidlula imijikelezo yokushaja engu-2,000, okusho ukuthi ngisho nokushaja kwansuku zonke, kungahlala iminyaka engaphezu kwemihlanu. Ukusetshenziswa okuvamile kwasekhaya, lapho ukushaja kwenzeka njalo ezinsukwini ezintathu, kungahlala iminyaka engaba ngu-8. Ngenxa yokusebenza kabi kwezinga lokushisa eliphansi, amabhethri e-LiFePO4 avame ukuba nesikhathi sokuphila eside ezindaweni ezifudumele.
Isikhathi sesevisi sephakethe lebhethri le-LiFePO4 singafinyelela cishe imijikelezo engu-5,000, kodwa kubalulekile ukuqaphela ukuthi ibhethri ngalinye linenani elithile lemijikelezo yokushaja kanye nokukhipha (isb. imijikelezo engu-1,000). Uma leli nani lidluliwe, ukusebenza kwebhethri kuzokwehla. Ukukhipha okuphelele kuthinta kakhulu isikhathi sokuphila kwebhethri, ngakho-ke kubalulekile ukugwema ukukhipha ngokweqile.
Izinzuzo zama-LiFePO4 Battery Packs Uma kuqhathaniswa nama-Lead-Acid Battery:
Amandla Aphezulu: Amaseli e-LiFePO4 angasukela ku-5Ah kuya ku-1000Ah (1Ah = 1000mAh), kanti amabhethri e-lead-acid ngokuvamile asukela ku-100Ah kuya ku-150Ah ngeseli ngalinye le-2V, ngokuguquguquka okulinganiselwe.
Isisindo Esilula: Iphakethe lebhethri le-LiFePO4 elinomthamo ofanayo lingaba yizingxenye ezimbili kwezintathu zomthamo kanye nengxenye eyodwa kwezintathu zesisindo sebhethri le-lead-acid.
Amandla Okushaja Okusheshayo Aqinile: Ugesi wokuqala wephakethe lebhethri le-LiFePO4 ungafinyelela ku-2C, okwenza kube nokushaja okuphezulu. Ngokuphambene nalokho, amabhethri e-lead-acid ngokuvamile adinga ugesi ophakathi kuka-0.1C no-0.2C, okwenza kube nzima ukushaja okusheshayo.
Ukuvikelwa Kwemvelo: Amabhethri e-lead-acid aqukethe inani elikhulu le-lead, elikhiqiza imfucuza eyingozi. Ngakolunye uhlangothi, amaphakethe ebhethri e-LiFePO4 awanazo izinsimbi ezisindayo futhi awabangeli ukungcola ngesikhathi sokukhiqizwa nokusetshenziswa.
Izindleko Ezisebenzayo: Nakuba amabhethri e-lead-acid ekuqaleni eshibhile ngenxa yezindleko zawo zezinto zokwakha, amabhethri e-LiFePO4 abonakala engabizi kakhulu ngokuhamba kwesikhathi, uma ubheka impilo yawo yesevisi ende kanye nezidingo zokunakekelwa eziphansi. Ukusetshenziswa okusebenzayo kubonisa ukuthi ukusebenza kahle kwamabhethri e-LiFePO4 kungaphezu kokuphindwe kane kunamabhethri e-lead-acid.
