Yiziphi izinzuzo zamabhethri elanga LiFePo4?

Ukwakhiwa kweSolarI-LiFePo4ibhethri Isici esiyingqayizivele seIbhethri ye-solar LiFePo4(ibhethri ye-lithium iron phosphate) ukusetshenziswa kwe-olive crystal structure, icrystal iwumumo ngemva kokucwebezeliswa, ihlukaniswe yaba i-ionic / molecular / atomic / metal crystal, i-lithium-ion battery ionic crystal ithathwa ezintweni zayo ze-cathode ekuhleleni ama-ionic compounds. esimweni sencazelo, okungukuthi, ngeqembu le-ion eliphozithivu nelingemuhle engxenyeni ethile yekristalu eyakhiwe ngokuhlangana kwe-ionic. Ngokuvamile, amakristalu e-ionic ayashwabana futhi aqinile, anezici zamaphuzu ancibilika kakhulu futhi abilayo, futhi angahambisa ugesi lapho encibilikile noma encibilika. Isisekelo sawo wonke amabhethri e-lithium-ion, kuhlanganise nobuchwepheshe be-lithium iron phosphate, i-ionic conductivity. Iningi le-crystal structure yangaphakathi ye-lithium-ion battery cathode ithatha i-"spinel structure", i-lithium manganate, i-lithium cobaltate, i-ternary lithium amabhethri anjalo, lesi sakhiwo siqukethe amayunithi ayisishiyagalombili amancane angama-cubic akhiwa amaseli e-spinel (amayunithi enza phezulu kwekristalu, ingaqondwa ngokoqobo njengamaseli ekristalu), amaseli abe esehlanganiswa abe isakhiwo sekristalu ye-octahedral. Ngokuphambene, ukwakheka komnqumo kwamakristalu e-lithium iron phosphate angamakholomu amafushane. Isakhiwo somgogodla wamabhethri e-lithium angenhla anezici zawo. Amabhethri e-lithium cobalt-acid anokusebenza okuhle kakhulu jikelele, kodwa umthamo ophansi nezinkinga zokuphepha, futhi abiza kakhulu ukumaketha; amabhethri e-lithium manganenate ngenxa yokufinyelela okuhle kwezinto zokwakha, izindleko eziphansi nokuphepha, kodwa ukusebenza komjikelezo ompofu nokusebenza kwesitoreji; I-ternary lithium amabhethri ahloselwe ukuvumelanisa ukushiyeka kwalaba ababili, umthamo unyukile, futhi ukuzinza kwesakhiwo kuye kwathuthukisa ukuphepha, kodwa intengo namanje ibiza kakhulu, ngoba idinga futhi i-cobalt yezinto zokusetshenziswa zamasu. Ukungalungi okujwayelekile komgogodlaibhethri ye-lithium-ionukuthi amandla awawona amakhulu, awafaneleki ngezinga elikhulu. Yiziphi Izimpawu zamabhethri eSolar LiFePo4? Izici zobuchwepheshe bebhethri yeSolar LiFePo4 kanye nezomnotho, ngakolunye uhlangothi, zilungele isimo semakethe yokugcina amandla ekhaya. Ngokuqondile. 1. I-voltage yebhethri ye-solar LiFePo4 ilinganiselwe: i-voltage yegama 3.2V, i-voltage yokushaja yokuqedwa 3.6V, i-termination discharge voltage 2.0V. 2. umthamo wetiyori ophezulu, nokuminyana kwamandla okungu-170mAh/g. 3. ukuzinza okuhle kokushisa nokumelana nokushisa okuphezulu. 4. ukugcinwa kwamandla okumaphakathi, impahla ye-cathode ehambisana nezinhlelo eziningi ze-electrolyte. 5. I-voltage yokuqeda engu-2.0V, engakhipha umthamo owengeziwe, ukukhishwa okukhulu nokulinganiselwe. 6. Izici ezinhle zeplathifomu kagesi kagesi, kanye nebhalansi yesikhulumi samandla kagesi ashajayo kanye nokushajwa kungase kusondele kuleyo yokuphakelwa kwamandla okulawulwayo. Izici zobuchwepheshe ezingenhla zenza amandla aphezulu nokuphepha kube kuhle ukufezwa, okukhuthaza kakhulu ukusetshenziswa kwebhethri ye-LiFePo4 enkulu. Ngaphezu kwezici zobuchwepheshe, amabhethri e-LiFePo4 anezinzuzo ezimbili ezithengiswayo: 1. izinto zokusetshenziswa ezishibhile, izinsiza eziningi; 2. ayinazo izinsimbi eziyigugu, ezingenabuthi, iwumkhiqizo ohambisana nemvelo. Lokhu kwenza ukusetshenziswa kwebhethri ye-lithium iron phosphate emakethe yezimoto zamandla entsha yamanje kukhanye, futhi kube ubuchwepheshe bokugcina amandla obukhethwayo bezinhlelo zokugcina ilanga zasekhaya. I-Solar Lithium iron Phosphate ne-Lithium Manganate, i-Lithium Cobaltate, Ukuqhathaniswa kwebhethri ye-Ternary Lithium I-LiFePo4battery kanye ne-lithium manganate, i-lithium cobaltate, amabhethri e-lithium ternary ayigatsha elifanayo lamabhethri e-lithium-ion, ukusebenza kwawo kusebenza ikakhulukazi ekusetshenzisweni kwamandla elanga, okubizwa ngokuthi amabhethri e-solar lithium iron phosphate, eyaziwa nangokuthi amabhethri e-lithium-iron. Ngakho-ke, izinzuzo zebhethri ye-solar lithium iron phosphate ikakhulukazi ibhekisela ekuqhathaniseni kwayo namanye amabhethri ekusetshenzisweni kokugcina amandla. Ngalo mqondo, izoqhathanisa ikakhulukazi izinzuzo zayo ezihambisanayo namabhethri e-ternary lithium namabhethri e-lead-acid. Okokuqala, inzuzo yokumelana nezinga lokushisa eliphezulu uma kuqhathaniswa namabhethri e-ternary lithium. Amabhethri e-SolarLiFePo4 asebenza kangcono izinga lokushisa eliphezulu, angamelana nezinga lokushisa eliphezulu lika-350 ° C ~ 500 ° C, kuyilapho i-lithium manganate / i-lithium cobaltate ivamise ukuba ngu-200 ° C kuphela, izinto zebhethri ze-lithium eziguquliwe zizoba cishe ukubola okungama-200 ° C. Okwesibili, abathathu phakathi "kwabadala" - inzuzo ephelele yokuphila isikhathi eside. Amabhethri e-lithium iron phosphate kunamabhethri e-lead-acid kanye namabhethri e-ternary lithium anokuphila komjikelezo omude. Amabhethri e-lead-acid "empilweni ende" cishe izikhathi ezingu-300, kuze kube izikhathi ezingu-500; I-ternary lithium amabhethri ngokwethiyori afika ku-2000 izikhathi, isicelo sangempela cishe izikhathi eziyi-1000 umthamo uzobola ukuya ku-60%; kanye nokuphila kwebhethri ye-lithium iron phosphate izikhathi ezingu-2000, lapho kusekhona i-95% yomthamo, umqondo wokuphila komjikelezo kakhudlwana Finyelela izikhathi ezingaphezu kuka-3000. Uma kuqhathaniswa namabhethri e-lead-acid anezinzuzo eziningi 1. Umthamo omkhulu.I-Monomer ingenziwa ibe ngu-5Ah ~ 1000 Ah (1 Ah = 1000m Ah), kuyilapho ibhethri eliholayo elingu-2V monomer livamise ukuba ngu-100Ah ~ 150 Ah, ububanzi bokushintsha buncane. 2. Isisindo esincane.Umthamo ofanayo wevolumu yebhethri ye-solar LiFePo4 ingu-2/3 wevolumu yamabhethri e-lead-acid, isisindo singu-1/3 wakamuva. 3. Ikhono lokushaja ngokushesha.Ibhethri yeSolar LiFePo4 ishaja njengamanje ifika ku-1C, ukufeza izinga elikhulu lokushaja; ibhethri le-lead-acid yamanje iyadingeka ngokuvamile phakathi kuka-0.1C ~ 0.2C, ayikwazi ukufinyelela ukusebenza kokushaja okusheshayo. 4. Ukuvikelwa kwemvelo. Amabhethri e-lead-acid akhona ngobuningi bezinsimbi ezisindayo - umthofu, akhiqiza uketshezi olulahlwayo, kuyilapho amabhethri elanga LiFePo4 engenazo izinsimbi ezinzima, akukho ukungcola ekukhiqizeni nasekusetshenzisweni. 5. Ukusebenza kwezindleko eziphezulu.Nakuba amabhethri e-lead-acid ngenxa yezinto zawo ezishibhile, izindleko zokuthola ziphansi kunebhethri ye-solar LiFePo4, kodwa empilweni yesevisi kanye nokugcinwa kwesimiso somnotho kuphansi kunebhethri ye-solar LiFePo4. Imiphumela yohlelo lokusebenza ibonisa ukuthi: ibhethri ye-solar lithium iron phosphate ingaphezu kokuphindwe kane kunokusebenza kwezindleko zamabhethri e-lead-acid. Izinhlelo ze-Solar LiFePo4battery ngokuqinisekile zibheke kakhuluukugcinwa kwamandla, okunqunywa izinzuzo ezihlukahlukene ezikhonjiswe kulesi siqhathaniso esingenhla, uma ukuminyana kwamandla kanye nesiphindaphindi sokukhipha kanye nezinye izici bese wenza okuthile ukuthuthukisa, i-lithium iron solar phosphate izobaukukhetha kwesitoreji samandla somndeni!
