Iibhetri ezenziwe nge-lithium iron phosphate (LiFePO4) zihamba phambili kwi-teknoloji yebhetri.Iibhetri zinexabiso eliphantsi kunoninzi lwabakhuphisana nabo kwaye azinayo i-cobalt yensimbi enetyhefu.Azinatyhefu kwaye ziphila ixesha elide.Kwixesha elizayo elingekude, ibhetri yeLiFePO4 inika isithembiso esihle.Iibhetri ezenziwe nge-lithium iron phosphate zisebenza kakhulu kwaye zizinzileyo.
Xa ingasetyenziswa, ibhetri ye-LiFePO4 iyazikhupha ngesantya se-2% kuphela ngenyanga ngokuchasene ne-30% yeebhetri ze-lead-acid.Kuthatha ngaphantsi kweeyure ezimbini ukutshaja ngokupheleleyo.Iibhetri ze-Lithium-ion polymer (LFP) zinokuxinwa kwamandla ngokuphindwe kane xa kuthelekiswa neebhetri ze-lead-asidi.Ezi bhetri zinokutshajwa ngokukhawuleza kuba zifumaneka kwi-100% yomthamo wazo opheleleyo.Ezi zinto zinegalelo ekusebenzeni kakuhle kwe-electrochemical ye-LiFePO4 iibhetri.
Ukusetyenziswa kwezixhobo zokugcina amandla ebhetri kunokwenza ukuba amashishini achithe kancinci kumbane.Amandla ahlaziyekayo awongezelelweyo agcinwa kwiinkqubo zebhetri ukuze asetyenziswe kamva lishishini.Ukungabikho kwenkqubo yokugcina amandla, amashishini anyanzelekile ukuba athenge amandla kwigridi kunokusebenzisa izixhobo zabo eziphuhliswe ngaphambili.
Ibhetri iyaqhubeka nokuhambisa umbane kunye namandla afanayo naxa igcwele i-50%.Ngokungafaniyo neentshaba zabo, iibhetri ze-LFP zinokusebenza kwindawo ezifudumeleyo.I-iron phosphate inesakhiwo esiqinileyo sekristale esichasayo ukuphuka ngexesha lokutshaja kunye nokukhupha, okukhokelela ekunyamezelweni komjikelo kunye nobomi obude.
Ukomelezwa kweebhetri zeLiFePO4 kubangelwa zizinto ezininzi, kubandakanywa ubunzima bazo.Banobunzima malunga nesiqingatha njengeebhetri ze-lithium eziqhelekileyo kunye neepesenti ezingamashumi asixhenxe njengeebhetri ezikhokelayo.Xa ibhetri ye-LiFePO4 isetyenziswa kwisithuthi, ukusetyenziswa kwegesi kuyancipha kwaye ukuhanjiswa kuphuculwe.
Ibhetri ehambelana nendalo
Kuba iibhetri ze-LiFePO4 zenziwa ngezinto ezingeyongozi, zenza umonakalo omncinci kwindalo kuneebhetri ze-lead-acid.Nyaka ngamnye, iibhetri ezineasidi yelothe zinobunzima obungaphezu kweetoni ezizizigidi ezithathu.
Ukubuyisela kwakhona iibhetri ze-LiFePO4 zivumela ukubuyiswa kwezinto ezisetyenziswe kwii-electrode zabo, ii-conductors, kunye nee-casings.Ukongezwa kwezinye zezi zinto kunokunceda iibhetri ezintsha ze-lithium.Le chemistry ye-lithium inokunyamezela amaqondo obushushu aphezulu kakhulu, iyenza ilungele iiprojekthi zamandla ezifana neenkqubo zamandla elanga kunye nokusetyenziswa kwamandla aphezulu.Ithuba lokuthenga iibhetri ze-LiFePO4 ezenziwe kwizinto ezinokuphinda zisetyenziswe ziyafumaneka kubathengi.Nangona iinkqubo zokurisayikilishwa zisaphuhliswa, inani elikhulu leebhetri ze-lithium ezisetyenziselwa ukuthutha amandla kunye nokugcinwa zisasebenza ngenxa yobude bazo obude.
Izicelo ezininzi zeLiFePO4
Ezi bhetri zisetyenziswa kwiimeko ezininzi ezahlukeneyo, ezifana neepaneli zelanga, iimoto, izikhephe kunye nezinye iinjongo.
Ibhetri ye-lithium ethembekileyo nekhuselekileyo yokusetyenziswa kwezorhwebo yiLiFePO4.Ke ngoko zigqibelele kusetyenziso lwezorhwebo olufana neelifgates kunye noomatshini bomgangatho.
Itekhnoloji yeLiFePO4 iyasebenza kwiinkalo ezininzi ezahlukeneyo.Ukuloba kwi-kayak kunye nezikhephe zokuloba kuthatha ixesha elingakumbi xa ixesha lokubaleka kunye nexesha lokuhlawula lide kwaye lifutshane, ngokulandelanayo.
Uphononongo lwakutsha nje kwiibhetri ze-lithium iron phosphate zisebenzisa i-ultrasound.
Rhoqo ngonyaka, zininzi kwaye zisetyenziswa ngakumbi iibhetri ze-lithium iron phosphate.Ukuba ezi bhetri azilahlwanga ngexesha elifanelekileyo, ziya kubangela ukungcoliseka kwendalo kwaye zitye izibonelelo ezininzi zetsimbi.
Uninzi lweentsimbi eziya ekwakhiweni kweebhetri ze-lithium iron phosphate zifumaneka kwi-cathode.Isigaba esibalulekileyo kwinkqubo yokubuyisela iibhetri ze-LiFePO4 eziphelileyo yindlela ye-ultrasonic.
Ukufotowa kwe-high-speed, i-Modeling Fluent, kunye nenkqubo yokukhupha isetyenziselwa ukuphanda i-bubble ye-airborne dynamic mechanism ye-ultrasonic ekupheliseni izinto ze-lithium phosphate cathode ukwenzela ukuba kudlule imida yendlela ye-LiFePO4 yokubuyisela kwakhona.I-LiFePO4 powder efunyenweyo ineempawu ezibalaseleyo ze-electrochemical kunye nokusebenza kakuhle kwe-lithium iron phosphate recovery kwaba yi-77.7%.Inkunkuma ye-LiFePO4 yafunyanwa kusetyenziswa indlela entsha yokukhupha ekwenziweni kulo msebenzi.
Itekhnoloji yokuPhucula iLithium yentsimbi yePhosphate
Iibhetri zeLiFePO4 zilungile kwindalo esingqongileyo kuba zinokutshajwa kwakhona.Xa kuziwa ekugcineni amandla avuselelekayo, iibhetri ziyasebenza, zithembekile, zikhuselekile, kwaye ziluhlaza.Inoveli ye-lithium iron phosphate compounds inokudalwa ngakumbi kusetyenziswa indlela ye-ultrasonic.
