Intshayelelo:
Kule mihla yokhuseleko lokusingqongileyo kunye netekhnoloji, izithuthi zombane ziya zithandwa ngakumbi kwaye ziya kuthatha indawo yezithuthi zepetroli zemveli kwixesha elizayo.ibhetri ye-lithiumyintliziyo yesithuthi sombane, esinika amandla afunekayo ukuze isithuthi sombane siqhubeke phambili. Ubomi benkonzo kunye nokhuseleko lweebhetri zesithuthi sombane zezona zinto zixhalabisayo kubanini beemoto. Nangona kunjalo, le micimbi mibini inxulumene kakhulu nendlela echanekileyo yokutshaja. Iibhetri ezisetyenziswa kwizithuthi zombane ngoku ziquka iibhetri ze-ternary lithium kunye neebhetri ze-lithium iron phosphate. Ezi ndlela zimbini ziya kuba naliphi ifuthe kwezi bhetri zimbini? Masixoxe ngazo kunye.
Impembelelo yokusebenzisa iibhetri ze-ternary lithium uze uzitshaje emva koko
1. Ukubola komthamo: Ngalo lonke ixesha amandla ebhetri ye-ternary lithium esetyenziswa aze aphinde atshajwe, kukukhupha okunzulu, okunokubangela ukuba umthamo webhetri ye-ternary lithium ubole kancinci kancinci, ixesha lokutshaja lifutshane, kwaye uluhlu lokuqhuba lunciphe. Umzekelo, umntu wenze uvavanyo. Emva kokuba ibhetri ye-ternary lithium ikhutshwe ngokunzulu izihlandlo ezili-100, umthamo uyancipha ngama-20% ~ 30% xa kuthelekiswa nexabiso lokuqala. Oku kungenxa yokuba ukukhupha okunzulu kubangela umonakalo kwizinto ze-electrode, ukubola kwe-electrolyte, kunye nokuhla kwe-lithium yesinyithi kutshabalalisa ukusebenza kwebhetri kunye nokukhupha, okubangela ukwehla kwamandla, kwaye lo monakalo awunakuguqulwa.
2. Ubomi obufutshane: Ukukhupha okunzulu kuya kukhawulezisa izinga lokuguga kwezinto zangaphakathi zebhetri ye-ternary lithium, kunciphise ukusebenza kokutshaja kunye nokukhupha kwebhetri, kunciphise inani lokutshaja kunye nokukhupha umjikelo, kwaye kunciphise ubomi benkonzo.
3. Ukutshaja okunciphileyo kunye nokusebenza kakuhle kokukhupha: Ukusebenzisa amandla aphezulu uze utshaje kwakhona kuya kubangela ukuba ii-electrode ezilungileyo nezingalunganga zebhetri ye-ternary lithium zi-polarize, zonyuse ukumelana kwangaphakathi kwebhetri, zinciphise ukusebenza kakuhle kokutshaja, zandise ixesha lokutshaja, zinciphise amandla ebhetri, kwaye zinciphise kakhulu ubungakanani bamandla anokuphuma.
4. Iingozi zokhuseleko ezikhulayo: Ukukhupha amanzi anzulu ixesha elide kunokubangela iipleyiti zangaphakathi ze-ternaryibhetri ye-lithiumukuguquguqula okanye ukwaphuka, okubangela ukujikeleza okufutshane ngaphakathi kwebhetri kunye nomngcipheko womlilo nokuqhuma. Ukongeza, ukukhupha ibhetri nzulu kwandisa ukumelana kwayo kwangaphakathi, kunciphisa ukusebenza kakuhle kokutshaja, kwaye kwandisa ukuveliswa kobushushu ngexesha lokutshaja, okunokubangela ukuba ibhetri ye-ternary lithium idumbe kwaye iguquguquke, kwaye ibangele nokubaleka kobushushu, ekugqibeleni okukhokelela ekuqhumeni nasemlilo.
Ibhetri ye-lithium ye-Ternary yeyona bhetri yesithuthi sombane ilula kwaye inamandla kakhulu, kwaye isetyenziswa ngokubanzi kwizithuthi zombane eziphezulu. Ukuze kuthintelwe iziphumo ezimbi zokukhupha umbane ngokunzulu kwibhetri, ibhetri ixhotyiswe ngebhodi yokukhusela. I-voltage yebhetri ye-lithium ye-ternary enye etshajelwe ngokupheleleyo imalunga ne-4.2 volts. Xa i-voltage enye ikhutshelwa kwi-2.8 volts, ibhodi yokukhusela iya kuyinqumla ngokuzenzekelayo i-power supply ukuthintela ibhetri ekukhupheni umbane ngokugqithisileyo.
Impembelelo yokutshaja njengoko usiya kwiibhetri ze-ternary lithium
Inzuzo yokutshaja njengoko uhamba kukuba amandla ebhetri axhomekeke ekutshajeni okuncinci kunye nokukhupha okuncinci, kwaye ahlala egcina inqanaba eliphezulu lamandla ukuze kuthintelwe imiphumo emibi yamandla aphantsi kwibhetri. Ukongeza, ukutshaja okuncinci kunye nokukhupha okuncinci kunokugcina umsebenzi wee-ion ze-lithium ngaphakathi kwe-ternary.ibhetri ye-lithium, ukunciphisa ngempumelelo isantya sokuguga kwebhetri, kwaye kuqinisekiswe ukuba ibhetri inokukhupha amandla ngokuzinzileyo ngexesha lokusetyenziswa kwayo okulandelayo, kwaye inokwandisa ubomi bebhetri. Okokugqibela, ukutshaja njengoko uqhubeka kunokuqinisekisa ukuba ibhetri isoloko ikwimeko yamandla aneleyo kwaye yonyuse uluhlu lokuqhuba.
Impembelelo yokutshaja kwakhona emva kokusetyenziswa kwiibhetri ze-lithium iron phosphate
Ukutshaja kwakhona emva kokusetyenziswa kukukhupha okunzulu, okuya kuba nemiphumo emibi kwisakhiwo sangaphakathi seebhetri ze-lithium iron phosphate, okubangela umonakalo kwizinto zangaphakathi zebhetri, ukukhawulezisa ukuguga kwebhetri, ukwandisa ukumelana kwangaphakathi, ukunciphisa ukusebenza kakuhle kokutshaja nokukhupha, kunye nokwandisa ixesha lokutshaja. Ukongeza, emva kokukhupha okunzulu, impendulo yeekhemikhali yebhetri iyaqina kwaye ubushushu buyanda kakhulu. Ubushushu obuveliswayo abupheli ngexesha, nto leyo enokubangela ukuba ibhetri ye-lithium iron phosphate ivuthuluke kwaye iguquguquke. Ibhetri evuthuzayo ayinakuqhubeka nokusetyenziswa.
Impembelelo yokutshaja njengoko uqhubeka ne-lithium iron phosphate
Ngokwendlela eqhelekileyo yokutshaja nokukhupha i-lithium iron phosphate, iibhetri ze-lithium iron phosphate zinokutshajwa kwaye zikhutshwe izihlandlo ezingaphezu kwama-2,000. Ukuba ukutshaja njengoko kufunekayo kukutshaja okungaphantsi kunye nokukhupha okungaphantsi, ubomi benkonzo yeebhetri ze-lithium iron phosphate bunokwandiswa ukuya kwinqanaba eliphezulu. Umzekelo, ibhetri ye-lithium iron phosphate inokutshajwa kwaye ikhutshwe ukusuka kwi-65% ukuya kwi-85% yamandla, kwaye ubomi bokutshaja nokukhupha umjikelo bunokufikelela amaxesha angaphezu kwama-30,000. Kuba ukukhupha okungaphantsi kunokugcina amandla ezinto ezisebenzayo ngaphakathi kwebhetri ye-lithium iron phosphate, kunciphise izinga lokuguga kwebhetri, kwaye kwandise ubomi bebhetri ukuya kwinqanaba eliphezulu.
Ingxaki kukuba ibhetri ye-lithium iron phosphate ayilunganga kakuhle. Ukutshaja nokukhupha amanzi rhoqo kunokubangela impazamo enkulu kwi-voltage yeeseli zebhetri ye-lithium iron phosphate. Ukuqokelelana ixesha elide kuya kubangela ukuba ibhetri yonakale ngexesha elinye. Ngamafutshane, kukho impazamo kwi-voltage yebhetri phakathi kweseli nganye. Ixabiso lempazamo lidlula uluhlu oluqhelekileyo, oluya kuchaphazela ukusebenza, imileage kunye nobomi benkonzo yephakheji yebhetri yonke.
Isiphelo
Ngolu hlalutyo lokuthelekisa olungentla, umonakalo obangelwe ziibhetri ezimbini ngokutshaja emva kokuba amandla ebhetri ephelile awunakuguqulwa, kwaye le ndlela ayicebisi. Ukutshaja njengoko usebenzisa kuluncedo kakhulu kwibhetri, kwaye impembelelo embi ebangelwa yiyoibhetri ye-lithiumincinci kakhulu, kodwa ayiyondlela ichanekileyo yokutshaja. Oku kulandelayo kwabelana ngendlela echanekileyo yokutshaja ukwandisa ukhuseleko lokusetyenziswa kwebhetri nokwandisa ubomi benkonzo.
1. Kuphephe ukukhupha umbane kakhulu: Xa imitha yamandla yemoto yombane ibonisa ukuba amandla ebhetri asele ngama-20 ~ 30%, emva kokusebenzisa imoto ehlotyeni, yiya kwindawo yokutshaja ukuze uvumele ibhetri iphole imizuzu engama-30 ukuya kwiyure ngaphambi kokuba itshaje, nto leyo enokuthintela ubushushu bokutshaja kwebhetri ekubeni bube phezulu kakhulu, kwaye kwangaxeshanye uphephe iziphumo ezimbi zokukhupha umbane kakhulu kwibhetri.
2. Kuphephe ukutshaja kakhulu: Amandla ebhetri asele ngama-20~30%. , Kuthatha malunga neeyure ezisi-8~10 ukutshaja ngokupheleleyo. Kucetyiswa ukuba umbane ungacinywa xa umbane utshajwa ukuya kuma-90% ngokwesibonisi semitha yamandla, kuba ukutshaja ukuya kuma-100% kuya kwandisa ukuveliswa kobushushu kwaye iingozi zomngcipheko wokhuseleko ziya kwanda ngokukhawuleza, ngoko ke umbane ungacinywa xa utshajwa ukuya kuma-90% ukuze kuthintelwe iziphumo ezimbi zenkqubo kwibhetri. Iibhetri ze-lithium iron phosphate zinokutshajwa ukuya kuma-100%, kodwa kufuneka kuqatshelwe ukuba umbane kufuneka ucinywe ngexesha emva kokuba utshajwe ngokupheleleyo ukuze kuthintelwe ukutshaja kakhulu.
