Izinhlobo Ezimbili Zebhethri Le-Lithium-Ion Ezivamile - i-LFP kanye ne-NMC, Uyini Umehluko?

Ibhethri ye-lithium- LFP Vs NMC

Amagama e-NMC ne-LFP adumile muva nje, njengoba izinhlobo ezimbili zamabhethri zibanga ukuvelela.Lobu akubona ubuchwepheshe obusha obuhlukile kumabhethri e-lithium-ion.I-LFP ne-NMC ngamakhemikhali amabili ahlukene e-lithium-ion.Kodwa kungakanani okwaziyo nge-LFP ne-NMC?Izimpendulo ze-LFP vs NMC zonke zikulesi sihloko!

Uma ufuna ibhethri lomjikelezo ojulile, kunezinto ezimbalwa ezibalulekile okufanele ucabange ngazo, okuhlanganisa ukusebenza kwebhethri, ukuphila isikhathi eside, ukuphepha, intengo, kanye nenani lilonke.

Ake siqhathanise amandla nobuthakathaka bamabhethri e-NMC ne-LFP (Ibhethri le-LFP VS Ibhethri le-NMC).

Liyini ibhethri le-NMC?

Ngamafuphi, amabhethri e-NMC anikezela ngenhlanganisela ye-nickel, manganese, ne-cobalt.Ngezinye izikhathi abizwa ngokuthi amabhethri e-lithium manganese cobalt oxide.

amabhethri akhanyayo anamandla athile aphezulu kakhulu noma amandla.Lo mkhawulo "wamandla" noma "amandla" uwenza asetshenziswe kakhulu kumathuluzi kagesi noma ezimotweni zikagesi.

Nokho, ngokuvamile, zombili izinhlobo ziyingxenye yomndeni we-lithium iron.Kodwa-ke, uma abantu beqhathanisa i-NMC ne-LFP, ngokuvamile babhekisela kumpahla ye-cathode yebhethri ngokwayo.

Izinto ezisetshenziswa ezintweni ze-cathode zingathinta kakhulu izindleko, ukusebenza, kanye nempilo.I-Cobalt iyabiza, futhi i-lithium ibiza kakhulu.Izindleko ze-Cathodic eceleni, ezinikeza uhlelo lokusebenza olungcono kakhulu lulonke?Sibheka izindleko, ukuphepha, nokusebenza kwempilo yonke.Funda futhi wenze imibono yakho.

Yini i-LFP?

Amabhethri e-LFP asebenzisa i-phosphate njenge-cathode material.Isici esibalulekile esenza i-LFP igqame umjikelezo wayo wempilo ende.Abakhiqizi abaningi banikeza amabhethri e-LFP ngempilo yeminyaka eyi-10.Ngokuvamile kubonakala njengenketho engcono yezinhlelo zokusebenza "zokubhala", njengokugcina ibhethri noma omakhalekhukhwini.

Ibhethri elikhanyayo lizinze kakhulu kune-NMC ngenxa yokwengezwa kwe-aluminium.Asebenza emazingeni okushisa acishe abe ngaphansi kakhulu.-4.4 c kuya ku-70 C. Lolu hlu olubanzi lokwehluka kwezinga lokushisa lunwebeka kakhulu kunamanye amabhethri amaningi omjikelezo ojulile, okulenza libe inketho efanelekile kumakhaya amaningi noma amabhizinisi.

Ibhethri ye-LFP futhi ingamelana ne-voltage ephezulu isikhathi eside.Lokhu kuhumusha ekuzinzeni kokushisa okuphezulu.Ukuncipha kokuzinza kwe-thermal, iyanda ingozi yokushoda kwamandla nemililo, njengoba kwenza i-LG Chem.

Ukuphepha kuhlale kuwukucatshangelwa okubalulekile.Udinga ukwenza isiqiniseko sokuthi noma yini oyingezayo ekhaya noma ebhizinisini lakho idlula ekuhlolweni kwamakhemikhali okuqinile ukuze usekele noma yiziphi izimangalo “zokukhangisa”.

Inkulumompikiswano isaqhubeka nokushuba phakathi kochwepheshe bezimboni futhi kungenzeka iqhubeke isikhathi esithile.Lokho kusho ukuthi i-LFP ibhekwa kabanzi njengenketho engcono yokugcina i-solar cell, yingakho abakhiqizi abaningi bebhethri abaphezulu manje bekhetha le khemikhali ngemikhiqizo yabo yokugcina amandla.

I-LFP Vs NMC: Uyini umehluko?

Ngokuvamile, i-NMCS yaziwa ngokuminyana kwayo okukhulu kwamandla, okusho ukuthi inani elifanayo lamabhethri lizokhiqiza amandla engeziwe.Ngokombono wethu, lapho sihlanganisa izingxenyekazi zekhompuyutha nesofthiwe yephrojekthi, lo mehluko uthinta ukwakheka kwegobolondo lethu kanye nezindleko.Ngokuya ngebhethri, ngicabanga ukuthi izindleko zezindlu ze-LFP (ukwakhiwa, ukupholisa, ukuphepha, izingxenye zikagesi ze-BOS, njll.) cishe izikhathi ezingu-1.2-1.5 ngaphezu kwe-NMC.I-LFP yaziwa njengekhemistri ezinzile, okusho ukuthi umkhawulo wezinga lokushisa oshisayo (noma umlilo) uphakeme kune-NCM.Lokhu sikubone mathupha lapho sihlola ibhethri ukuthola isitifiketi se-UL9540a.Kodwa futhi kukhona ukufana okuningi phakathi kwe-LFP ne-NMC.Ukusebenza kahle kohambo olubuyayo kuyafana, kanye nezici ezivamile ezithinta ukusebenza kwebhethri, njengezinga lokushisa kanye nezinga elingu-C (izinga ibhethri elishajwa ngalo noma elikhishwa ngalo).
