Iibhetri zemoto yombane kunye neebhetri ze-liium-ion zokugcina amandla zinemilinganiselo eyahlukileyo, ngaphandle kokuba liLithium-ion. Ukuqonda ukungaboni ngasonye kuyanceda ukumisela le ibhetri yemfundo yakho, njengoko kungekho mntu-nto-yonke indlela.
Yintoni ibhetri ye-lithium-ion yogcino lwamandla olwenziwe?
Izicelo zokugcina amandla zifuna iibhetri ezinokuthenjwa, zihlala ixesha elide, kwaye zikhuselekile.
Isisombululo sethu sisebenzisa i-lithium i-inyibilium phosphate (LFP) i-Othode, elungele ezi mfuno. Unxibelelwano oluncinci phakathi kwe-LFP COHODE kunye ne-electrolyte ebangela ukuba igalelo kumjikelo wayo obalaseleyo ubomi kunye nokuzinza komtshato. Oku kuncitshise umngcipheko we ukubaleka kwe-thermal, imeko enokuba yingozi kwezinye iibhetri ze-lithium-ion.
Ngelixa i-LFP ibonelela ngokuthembeka okukhethekileyo kunye nokhuseleko, inoxinano lwamandla xa kuthelekiswa nezinye i-lithium-ion ye-lithium ye-lithium oxide (NMCCE). Ngenxa yoko, iibhetri ze-LFP zihlala zinzima kumgangatho onikiweyo, olona lufanelekileyo kwizithuthi zombane.
Yintoni ibhetri ye-lithium ye-ion yezithuthi zombane ezenziwe?
Izithuthi zombane zidinga iibhetri eziphezulu zokuxinana kwamandla ukulawula zombini iimoto kunye neenkqubo zayo zebhodi.
Uninzi lweemoto zombane zisebenzisa i-lithium-ion-ion-ion kunye ne-nickel kunye ne-cabalt cathodes, ebizwa Iibhetri ze-NMC. Oku kubonelela ngomthombo wamandla omda we-propulsion xa kuthelekiswa neebhetri ze-LFP.
Ulwelo lwezinto eziphilayo kwi-electrolyte kwiibhetri ze-NMC ziyaphendula ngeoksijini, ngakumbi kumaqondo obushushu aphezulu. Oku kuya kukhokelela kuqhumo kunye neminye imiba enokubakho enxulumene nokubaleka kwe-thermal.
Yintoni umahluko phakathi kweebhetri ze-lithium ze-ion yezakhono zokugcina kunye ne-lithium ze-ion yezithuthi zombane?
Iibhetri ze-LFP kunye ne-NMC zizisombululo zamandla ezigqwesileyo, kodwa zinemahluko ophambili ezenza babe zilungele imisebenzi ethile.
Izinto ze-Cathodede
Iibhetri zeLithium-ion Sebenzisa i-Cathode ukuvelisa amandla.
Ibhetri yokugcina amandla Sebenzisa i-LFP, ngelixa iibhetri zemoto zombane zisebenzisa i-NMC.
Iibhetri ze-NMC zinezinto ezixineneyo zamandla, ukuphucula ukukhawulezisa. Iibhetri ze-LFP zibonelela ngogcino lwamandla aphezulu xa kuthelekiswa ne-NMC.
I-OXYGEN ye-OXYGEN
I-NMC kunye ne-LFPTEies zombini ifuna i-electrolyte ukuba iphendule ngeoksijini. Nangona kunjalo, iibhetri ze-NMC zine-ooser yeoksijini ye-Olser ye-Olser, ibenza bathambekele ngakumbi kwi-thermal ebalekayo kunye nokuqhuma okunokwenzeka.
Ngokwahlukileyo, iibhetri ze-LFP zinokuba namandla okubaleka kwe-thermal, kubenzela ukhetho olukhuselekileyo ngokubanzi.
Shaja & Ukuqhuba
Iibhetri ze-NMC zinoxinzelelo lwamandla aphezulu kune-LFP, isebenze ngokukhawuleza ukutshaja nokuwukhuphela.
Inkqubo yokwaluphala kwebhetri
Iibhetri ze-NMC zisebenza kwi-3.7v, ngaphezulu kune-3.2v yeebhetri ze-LFP. Lo volimu uphakamileyo ukhokelela ekuthambekeni okukhawulezileyo njengeminyaka yebhetri.
iibhetri LFP’ I-voltage esezantsi ye-3.2V ibonelela ngozinzo olukhulu ngakumbi, okukhokelela ebomini bebhetri.
Imolekyuli enkulu ye-LFP ikwavumela ukwanda okulula kunye nokuthambeka ngexesha lokuhamba ngebhayisikile, ukuvumela iibhetri ze-LFP ukumelana namawaka emijikelezo yabo.
Iindleko
Iibhetri ze-LFP zihlala zixabisa kakhulu umjikelo ngamnye, zibenza babe nomtsalane ekusebenzeni kweendleko zexesha elide.
Iibhetri ze-NMC zibiza kakhulu ngenxa ye-cathodene ye-cathodene, kodwa zinokuba yindleko apho indawo kwaye ubunzima buyimiqobo, ngenxa yokusebenza kwabo kunye nobungakanani bendlela.
Yeyiphi ivolthi eyenza ibhetri ye-lithium-ion yokugcina amandla esebenza?
Ibhetri yeLithium-ion eyenzelwe ukugcinwa kwamandla isebenza kwi-3.2 volts kwiseli nganye. Eli vollige ihambelana nebhetri ye-Acid, esenza iibhetri ze-LFP zilungele iinkqubo ze-12, ezingama-24, okanye ezingama-48.
Yeyiphi ivostile esebenzisa ibhetri ye-lithium ye-ion yezithuthi zombane?
Iibhetri zemoto yombane isebenza kwi-3.7 volts volts kwiseli nganye, kunye ne-voltages yepakethi malunga nama-400 uVolts. I-voltage ephezulu inyusa intsebenzo phakathi kwe-electrolyte kunye ne-canode, ibonelela ngamandla ngakumbi kodwa inciphise ubomi bebhetri. Olu rhwebo lusenokungabi lulungelwe, kodwa luyifanela iimfuno zokuhambisa izithuthi zombane.
Ukuqukumbela
Ngelixa i-lithium-ion isetyenziselwa ukugcinwa kwamandla kunye nezithuthi zombane, iimfuno zabo ezichaziweyo zikhokelele kwi-chemisties eyahlukileyo.
Iinkqubo zokugcina zamandla zibeka phambili ukuthembeka, ixesha elide, kunye nokhuseleko, ukwenza i-lithium i-phosphate (LFP) i-Bterters efanelekileyo. Izibonelelo zabo zokuzinza kunye nokujikeleza kobomi.
Izithuthi zombane, nangona kunjalo, zifuna ukungcungcutheka kwezandla eziphezulu ukwandisa uluhlu lokuqhuba kunye nokusebenza, abavelisi abakhokelayo kwiibhetri ze-Ion-ion kunye ne-iNOBADS (NMC) baseCathodes (NMC) base-Cathodes. Nangona incinci kancinci kancinci kune-LFP, iibhetri ze-NMC zinokupakisha amandla angaphezulu kwiPhakethi encinci, elula – Elumkele kwizicelo zeselula.
