Insimu yobuchwepheshe bebhethri iholwa yi-lithium iron phosphate (LiFePO4)amabhethriAmabhethri awafaki i-toxin cobalt futhi ashibhile kakhulu kunezinye izindlela zawo eziningi. Awanabo ubuthi futhi ahlala isikhathi eside eshalofini. Ibhethri le-LiFePO4 linamandla amahle kakhulu esikhathini esizayo esibonakalayo.

Amabhethri e-Lithium Iron Phosphate: Ukukhetha Okusebenzayo Kakhulu Nokuvuselelwa Kabusha

Ibhethri le-LiFePO4 lingashaja kakhulu ngaphansi kwamahora amabili lishaja futhi uma ibhethri lingasetshenziswa. Izinga lokuzikhipha liyi-2% kuphela ngenyanga, kanti izinga lamabhethri e-lead-acid lingu-30%.

Uma kuqhathaniswa namabhethri e-lead-acid, amabhethri e-lithium-ion polymer (LFP) anikeza amandla amaningi ngokuphindwe kane. Lawa mabhethri nawo anomthamo wawo ophelele ongu-100% futhi angalayishwa ngesikhathi esifushane ngenxa yalokho. Ngenxa yalezi ziguquguquko, ukusebenza kwe-electrochemical kweAmabhethri e-LiFePO4 iKusebenza kahle kakhulu.

Amadivayisi okugcina amandla ebhethri angasiza izinkampani ukunciphisa izindleko zazo zikagesi. Izinhlelo zebhethri zigcina amandla avuselelekayo engeziwe ukuze zisetshenziswe kamuva lapho inkampani iwadinga. Uma kungekho uhlelo lokugcina amandla, izinkampani kudingeka zithenge amandla kugridi kunokusebenzisa izinsiza zazo ezakhiwe ngaphambilini.

Ibhethri linamandla ahambisanayo anenani elifanayo lamandla kagesi ngisho noma ibhethri linamandla angu-50%. Amabhethri e-LFP, ngokungafani nabancintisana nawo, angasebenza emazingeni okushisa aphezulu. Isakhiwo sekristalu esiqinile se-iron phosphate ngeke siwohloke lapho sishaja futhi sikhipha, okuholela ekukhuthazeleni komjikelezo walo kanye nokuphila isikhathi eside.

Izinhlobo eziningi zinegalelo ekuthuthukiseni amabhethri e-LiFePO4, okuhlanganisa nesisindo sawo esiphansi. Alula cishe ngamaphesenti angama-50 kunamanye amabhethri e-lithium futhi alula cishe ngamaphesenti angama-70 kunamabhethri e-lead. Ukusebenzisa ibhethri le-LiFePO4 emotweni kuholela ekunciphiseni ukusetshenziswa kwegesi kanye nokuthuthukiswa kokuhamba.

Ibhethri Elilungele Imvelo

Uma kuqhathaniswa namabhethri e-lead-acid, amabhethri e-LiFePO4 amelela usongo oluphansi kakhulu endaweni ezungezile njengoba ama-electrode kulawa mabhethri akhiwe ngezinto ezingeyona ingozi. Njalo ngonyaka, inani lamabhethri e-lead-acid alahlwayo lidlula amathani ayizigidi ezintathu.

Izinto ezisetshenziswa kuma-electrode, izintambo, kanye nezimbobo zamabhethri e-LiFePO4 zingatholakala ngokuphinda zisetshenziswe lawa mabhethri. Amabhethri amasha e-lithium angazuza ngokufakwa kwalesi sici. Le khemikhali ethize ye-lithium ilungele imisebenzi yamandla aphezulu kanye nemiklamo yamandla njengokufakwa kwamandla elanga ngoba ingamelana namazinga okushisa aphezulu kakhulu.

Abathengi banenketho yokuthenga amabhethri e-LiFePO4 enziwe ngezinto zokuvuselela. Ngenxa yokuthi amabhethri e-lithium asetshenziselwa ukuthutha nokugcina amandla ahlala isikhathi eside kangaka, inani elikhulu lawo lihlala lisetshenziswa, naphezu kokuthi izinqubo zokuvuselela zisathuthukiswa.

Uhlu Olubanzi Lwezinhlelo Zokusebenza ze-LiFePO4

Lawa mabhethri adonselwa ukusetshenziswa ezindaweni eziningi ezahlukene, okuhlanganisa amaphaneli elanga, izimoto, izikebhe, nezinye izinhlelo zokusebenza.

I-LiFePO4 iyibhethri le-lithium eliphephe kakhulu nelihlala isikhathi eside elitholakalayo ukuze lisetshenziswe kwezentengiselwano. Ngakho-ke, lilungele ukusetshenziswa kwezimboni njengemishini yaphansi kanye namasango okuphakamisa.

Ubuchwepheshe be-LiFePO4 bungasetshenziswa ezinhlobonhlobo zezicelo. Ukuba nesikhathi eside sokusebenza kanye nesikhathi esifushane sokushaja kusho isikhathi esengeziwe sokudoba kuma-kayak nasezikebheni zokudoba.

Ucwaningo Olusha Lwendlela Yokusebenzisa I-Ultrasonic Kumabhethri E-Lithium Iron Phosphate

Inani lamabhethri e-lithium iron phosphate asetshenzisiwe likhula minyaka yonke; uma lawa mabhethri engasuswa ngesikhathi esifanele, azofaka isandla ekungcolisweni kwemvelo futhi adle inani elikhulu lemithombo yensimbi.

I-cathode yamabhethri e-lithium iron phosphate iqukethe inani elikhulu lezinsimbi ezakha ukwakheka kwawo. Indlela ye-ultrasonic iyisinyathelo esibalulekile enkambisweni yonke yokubuyisa amabhethri e-LiFePO4 akhishwe.

Ukuze kuxazululwe ukungasebenzi kahle kwendlela yokuvuselela kabusha i-LiFePO4, indlela yokusebenza kwe-bubble dynamic ye-ultrasonic ekususeni izinto ze-lithium phosphate cathode yahlolwa kusetshenziswa izithombe ezisheshayo kanye nokumodela okushelelayo, kanye nenqubo yokuzihlukanisa.

Ukusebenza kahle kokubuyisa i-lithium iron phosphate kufinyelele kumaphesenti angu-77.7, kanti i-LiFePO4 powder etholakele ibonise izici ezinhle kakhulu ze-electrochemical. Inqubo entsha yokususa ukubandakanyeka eyakhiwe kulo msebenzi yasetshenziswa ukubuyisa imfucuza ye-LiFePO4.

Intuthuko Entsha ye-Lithium Iron Phosphate

Amabhethri e-LiFePO4 angashajwa kabusha, okwenza abe yimpahla endaweni yethu. Ukusetshenziswa kwamabhethri njengendlela yokugcina amandla avuselelekayo kuyasebenza, kuthembekile, kuphephile, futhi kuyazuzisa indawo ezungezile. Intuthuko eyengeziwe yezinto ezahlukene ze-lithium iron phosphate ingadalwa kusetshenziswa inqubo ye-ultrasonic.
