Amabhethri enziwe nge-lithium iron phosphate (LiFePO4) ahamba phambili kubuchwepheshe bebhethri.Amabhethri ashibhile kunabaningi bezimbangi zawo futhi awanayo i-cobalt yensimbi enobuthi.Azinabo ubuthi futhi zineshalofu lesikhathi eside.Esikhathini esizayo esiseduze, ibhethri ye-LiFePO4 inikeza isithembiso esihle kakhulu.Amabhethri enziwe nge-lithium iron phosphate asebenza kahle kakhulu futhi azinzile.
Uma ingasetshenziswa, ibhethri le-LiFePO4 lizikhipha ngokwalo ngenani elingu-2% nje ngenyanga ngokuqhathaniswa no-30% wamabhethri e-lead-acid.Kuthatha ngaphansi kwamahora amabili ukushaja ngokugcwele.Amabhethri e-Lithium-ion polymer (LFP) anomthamo wamandla ophindwe kane uma eqhathaniswa namabhethri e-lead-acid.Lawa mabhethri angashajwa ngokushesha ngoba atholakala ngo-100% womthamo wawo ogcwele.Lezi zici zifaka isandla ekusebenzeni kahle kwe-electrochemical yamabhethri e-LiFePO4.
Ukusetshenziswa kwempahla yokugcina amandla ebhethri kungenza amabhizinisi asebenzise imali encane kugesi.Amandla avuselelekayo engeziwe agcinwa ezinhlelweni zebhethri ukuze asetshenziswe kamuva ibhizinisi.Uma lungekho uhlelo lokugcina amandla, amabhizinisi ayaphoqeleka ukuthi athenge amandla kugridi kunokuba asebenzise izinsiza zawo ezakhiwe ngaphambilini.
Ibhethri iyaqhubeka nokuletha inani elifanayo likagesi namandla ngisho noma igcwele ngo-50%.Ngokungafani nezimbangi zabo, amabhethri e-LFP angasebenza ezindaweni ezifudumele.I-iron phosphate inesakhiwo sekristalu esiqinile esimelana nokuwohloka lapho ishajwa futhi ikhishwa, okuholela ekukhuthazeleni komjikelezo nempilo ende.
Ukuthuthukiswa kwamabhethri e-LiFePO4 kubangelwa izinto eziningi, okuhlanganisa nesisindo sawo esingasindi.Zinesisindo esingangesigamu samabhethri e-lithium avamile namaphesenti angamashumi ayisikhombisa njengelebhethri lomthofu.Uma ibhethri le-LiFePO4 lisetshenziswa emotweni, ukusetshenziswa kwegesi kuyehla futhi ukulawuleka kuyathuthukiswa.
Ibhethri Elilungele Imvelo
Njengoba ama-electrode amabhethri e-LiFePO4 enziwe ngezinto ezingezona eziyingozi, adala umonakalo omncane kakhulu emvelweni kunamabhethri e-lead-acid.Unyaka ngamunye, amabhethri aneasidi yomthofu anesisindo esingaphezu kwamathani ayizigidi ezintathu.
Amabhethri e-LiFePO4 agaywa kabusha avumela ukutholwa kwezinto ezisetshenziswa kuma-electrode awo, ama-conductor, nama-casings.Ukwengezwa kokunye kwalokhu kungasiza amabhethri e-lithium amasha.Le chemistry ye-lithium ingabekezelela amazinga okushisa aphakeme kakhulu, iyenze ilungele amaphrojekthi wamandla afana nezinhlelo zamandla elanga kanye nezicelo zamandla aphezulu.Amathuba okuthenga amabhethri e-LiFePO4 enziwe ngezinto ezigaywa kabusha ayatholakala kubathengi.Nakuba izinqubo zokugaywa kabusha zisathuthukiswa, inani elikhulu lamabhethri e-lithium asetshenziselwa ukuthuthwa kwamandla nokugcinwa zisasetshenziswa ngenxa yobude bawo obunwetshiwe.
Izicelo eziningi ze-LiFePO4
Lawa mabhethri asetshenziswa ezimweni eziningi ezahlukahlukene, njengamaphaneli elanga, izimoto, izikebhe, nezinye izinjongo.
Ibhethri ye-lithium ethembeke kakhulu futhi evikelekile yokusetshenziswa kwezentengiso yi-LiFePO4.Ngakho-ke alungele ukusetshenziswa kwezohwebo njengama-liftgates nemishini yaphansi.
Ubuchwepheshe be-LiFePO4 busebenza emikhakheni eminingi eyahlukene.Ukudoba kuma-kayak nezikebhe zokudoba kuthatha isikhathi esiningi uma isikhathi sokusebenza nesikhathi sokushaja sisinde futhi sisifushane, ngokulandelana.
Ucwaningo lwakamuva lwamabhethri e-lithium iron phosphate lisebenzisa i-ultrasound.
Unyaka ngamunye, kunamabhethri e-lithium iron phosphate asetshenziswa kakhulu.Uma la mabhethri engalahlwa ngesikhathi esifanele, azodala ukungcoliswa kwemvelo futhi adle izinsiza eziningi zensimbi.
Iningi lezinsimbi ezingena ekwakhiweni kwamabhethri e-lithium iron phosphate atholakala ku-cathode.Isigaba esibalulekile ohlelweni lokubuyisela amabhethri e-LiFePO4 aphelile yindlela ye-ultrasonic.
Ukuthwebula izithombe ngesivinini esikhulu, ukumodela ngokushelelayo, kanye nenqubo yokukhipha isisu kwasetshenziswa ukuze kuphenywe indlela eguquguqukayo yebhamuza lasemoyeni ye-ultrasonic ekuqedeni izinto ze-lithium phosphate cathode ukuze kudlule imikhawulo yendlela yokuvuselela i-LiFePO4.I-LiFePO4 powder etholiwe inezindawo ezivelele ze-electrochemical kanye nokusebenza kahle kwe-lithium iron phosphate recovery kwaba ngu-77.7%.Imfucuza ye-LiFePO4 itholwe kusetshenziswa indlela yokukhipha inoveli edalwe kulo msebenzi.
Ubuchwepheshe Be-Lithium Iron Phosphate Ethuthukisiwe
Amabhethri e-LiFePO4 alungele imvelo ngoba angashajwa kabusha.Uma kuziwa ekugcineni amandla avuselelekayo, amabhethri ayasebenza, athembekile, aphephile, futhi aluhlaza.Inoveli ye-lithium iron phosphate compounds ingase idalwe ngokuqhubekayo kusetshenziswa indlela ye-ultrasonic.
