Intshayelelo:
Kwixesha lanamhlanje lokhuseleko lokusingqongileyo kunye nobuchwepheshe, izithuthi zombane ziya zithandwa kakhulu kwaye ziya kuthatha indawo yezithuthi zemveli zamafutha kwixesha elizayo. Iibhetri ye-lithiumyintliziyo yesithuthi sombane, esinika amandla afunekayo ukuze isithuthi sombane siqhubele phambili. Ubomi benkonzo kunye nokhuseleko lweebhetri zezithuthi zombane yimiba echaphazelekayo kubanikazi beemoto. Nangona kunjalo, le miba mibini inxulumene ngokusondeleyo kwindlela yokutshaja echanekileyo. Iibhetri ezisetyenziselwa izithuthi zombane ngoku ziquka iibhetri ze-lithium ze-ternary kunye neebhetri ze-lithium iron phosphate. Zeziphi iziphumo eziya kuba nazo ezi ndlela zimbini kwezi bhetri zimbini? Masiyixubushe kunye.
Impembelelo yokusetyenziswa phezulu kunye nokutshaja kwiibhetri ze-lithium ze-ternary
1. Ukubola kwamandla: Ngalo lonke ixesha amandla ebhetri ye-lithium ye-ternary esetyenzisiweyo kwaye aphinde ahlawulwe kwakhona, kukukhutshwa okunzulu, okunokubangela ukuba umthamo webhetri ye-lithium ye-lithium ubole ngokuthe ngcembe, ixesha lokutshaja lifutshane, kunye noluhlu lokuqhuba luyancipha. Umzekelo, umntu wenze umfuniselo. Emva kokuba ibhetri ye-lithium ye-ternary ikhutshwe ngokujulile ngamaxesha angama-100, umthamo uyancipha nge-20% ~ 30% xa kuthelekiswa nexabiso lokuqala. Oku kungenxa yokuba ukukhutshwa okunzulu kubangela umonakalo kwizinto ze-electrode, ukubola kwe-electrolyte, kunye nentsimbi ye-lithium precipitation itshabalalisa intlawulo yebhetri kunye nokusebenza kokukhutshwa, okubangela ukuhla kwamandla, kwaye lo monakalo awunakuguqulwa.
2. Ubomi obufutshane: Ukukhutshwa okujulileyo kuya kukhawulezisa izinga lokuguga kwezinto zangaphakathi ze-ternary lithium ibhetri, ukunciphisa intlawulo yebhetri kunye nokukhupha ukusebenza, ukunciphisa inani lentlawulo yomjikelo kunye nokukhutshwa, kunye nokunciphisa ubomi benkonzo.
3. Ukunciphisa intlawulo kunye nokusebenza kakuhle kokukhupha: Ukusebenzisa amandla kunye nokutshaja kwakhona kuya kubangela ukuba i-electrode echanekileyo kunye nengalunganga ye-ternary lithium ibhetri i-polarze, ukwandisa ukuchasana kwebhetri yangaphakathi, ukunciphisa ukusebenza kakuhle kokutshaja, ukwandisa ixesha lokutshaja, ukunciphisa umthamo webhetri, kunye nokunciphisa ngokuphawulekayo umthamo wamandla anokuthi aphuhliswe.
4. Imingcipheko eyongeziweyo yokhuseleko: Ukukhutshwa okunzulu kwexesha elide kunokubangela iiplati zangaphakathi ze-ternaryibhetri ye-lithiumukukhubaza okanye ukwaphuka, okukhokelela kwisekethe emfutshane ngaphakathi kwebhetri kunye nomngcipheko womlilo kunye nokudubula. Ukongeza, ukukhutshwa okunzulu kwebhetri kwandisa ukumelana kwayo kwangaphakathi, kunciphisa ukusebenza kakuhle kokutshaja, kwaye kwandisa ukuveliswa kobushushu ngexesha lokutshaja, okunokubangela lula ukuba ibhetri ye-lithium ye-ternary iqhume kwaye ikhubaze, kwaye ibangele ukubaleka kwe-thermal, ekugqibeleni kukhokelela ekuqhumeni kunye nomlilo.
I-Ternary lithium ibhetri yeyona nto ilula kwaye inamandla kakhulu ibhetri yemoto yombane, kwaye isetyenziswa ngokubanzi kwizithuthi zombane eziphezulu. Ukuze kuthintelwe imiphumo emibi yokukhutshwa okunzulu kwibhetri, ibhetri ixhotywe ngebhodi yokukhusela. Umbane webhetri ye-lithium etshaje ngokupheleleyo imalunga ne-4.2 volts. Xa i-voltage enye ikhutshwe kwi-volts ye-2.8, ibhodi yokukhusela iya kunqumla ngokuzenzekelayo ukunikezelwa kombane ukukhusela ibhetri ekukhupheni ngaphezulu.
Impembelelo yokutshaja njengoko uhamba kwiibhetri ze-ternary lithium
I-advanteji yokutshaja njengoko uhamba kukuba amandla ebhetri yeyokutshaja okunzulu kunye nokukhutshelwa okunzulu, kwaye ihlala igcina inqanaba lamandla aphezulu ukuphepha iziphumo ezibi zamandla aphantsi kwibhetri. Ukongeza, ukutshaja okunzulu kunye nokukhutshwa okunzulu kunokugcina umsebenzi we-lithium ion ngaphakathi kwe-ternary.ibhetri ye-lithium, ngokufanelekileyo ukunciphisa isantya sokuguga kwebhetri, kwaye uqinisekise ukuba ibhetri inokukhupha amandla ngokuzinzileyo ngexesha lokusetyenziswa okulandelayo, kwaye inokwandisa ubomi bebhetri. Ekugqibeleni, ukutshaja njengoko uhamba kunokuqinisekisa ukuba ibhetri ihlala ikwimo yamandla aneleyo kwaye yandise uluhlu lokuqhuba.
Impembelelo yokutshaja kwakhona emva kokusetyenziswa kwiibhetri ze-lithium iron phosphate
Ukutshaja kwakhona emva kokusetyenziswa kukukhutshwa okunzulu, okuya kuba nemiphumo emibi kwisakhiwo sangaphakathi se-lithium iron phosphate iibhetri, ezibangela umonakalo kwizinto zangaphakathi zesakhiwo sebhetri, ukukhawuleza ukuguga kwebhetri, ukwandisa ukumelana kwangaphakathi, ukunciphisa ukutshaja kunye nokukhupha ukusebenza kakuhle, kunye nokwandisa ixesha lokutshaja. Ukongezelela, emva kokukhutshwa okunzulu, ukuphendulwa kweekhemikhali zebhetri kuqinisa kwaye ukushisa kwanda ngokukhawuleza. Ubushushu obuveliswayo abuchithwanga ngexesha, elinokubangela ukuba ibhetri ye-lithium iron phosphate ibe lula kwaye ikhubazeke. Ibhetri egqumayo ayinakuqhubeka isetyenziswa.
Impembelelo yokutshaja njengoko uhamba kwi-lithium iron phosphate
Ngokutsho kokutshaja okuqhelekileyo kunye nokukhutshwa, iibhetri ze-lithium iron phosphate zinokuhlawuliswa kwaye zikhutshwe ngaphezu kwamaxesha angama-2,000. Ukuba ukutshaja njengoko usiya njengoko kufuneka kukutshaja okunzulu kunye nokukhupha okunzulu, ubomi benkonzo yeebhetri ze-lithium iron phosphate bunokwandiswa ukuya kuthi ga kwinqanaba eliphezulu. Ngokomzekelo, ibhetri ye-lithium yensimbi ye-phosphate inokuhlawuliswa kwaye ikhutshwe kwi-65% ukuya kwi-85% yamandla, kunye nentlawulo yomjikelo kunye nobomi bokukhutshwa kunokufikelela kumaxesha angaphezu kwama-30,000. Ngenxa yokuba ukukhutshwa okunzulu kunokugcina amandla ezinto ezisebenzayo ngaphakathi kwebhetri ye-lithium iron phosphate, ukunciphisa izinga lokuguga kwebhetri, kunye nokwandisa ubomi bebhetri ukuya kwinqanaba eliphezulu.
Ukungalungi kukuba ibhetri ye-lithium iron phosphate ayinakuhambelana kakuhle. Ukutshaja rhoqo kunye nokukhutshelwa okunganzulwanga kunokubangela impazamo enkulu kumbane weeseli zebhetri ye-lithium iron phosphate. Ukuqokelelana kwexesha elide kuya kubangela ukuba ibhetri ibe mbi ngexesha elinye. Ukuyibeka ngokulula, kukho impazamo kumbane webhetri phakathi kweseli nganye. Ixabiso lemposiso lidlula uluhlu oluqhelekileyo, oluya kuchaphazela ukusebenza, i-mileage kunye nobomi benkonzo yebhetri yonke.
Ukuqukumbela
Ngolu hlalutyo lothelekiso olungentla, umonakalo owenziwe kwiibhetri ezimbini ngokutshaja emva kokuba amandla ebhetri esetyenzisiwe ayinakuguqulwa, kwaye le ndlela ayicebisi. Ukutshaja njengoko usebenzisa kuhambelana nebhetri, kunye nefuthe elibi elibangwa yiibhetri ye-lithiumincinci ngokwentelekiso, kodwa asiyondlela ichanekileyo yokutshaja. Ezi zilandelayo zabelana ngendlela echanekileyo yokutshaja ukwandisa ukhuseleko lokusetyenziswa kwebhetri kunye nokwandisa ubomi benkonzo.
1. Gwema ukukhutshwa okugqithisileyo: Xa imitha yamandla emoto yombane ibonisa ukuba amandla ebhetri yi-20 ~ 30% eseleyo, emva kokusebenzisa imoto ehlobo, yiya kwindawo yokutshaja ukuze uvumele ibhetri ipholile imizuzu engama-30 ukuya kwiyure ngaphambi kokutshaja, enokuthintela ukushisa kwebhetri ukutshaja ekubeni kuphezulu kakhulu, kwaye kwangaxeshanye ugweme ukukhutshwa kweziphumo ezibi kwibhetri enzulu.
2. Kuphephe ukutshaja: Amandla ebhetri yi-20 ~ 30% eseleyo. , Kuthatha malunga ne-8 ~ 10 iiyure ukuhlawula ngokupheleleyo. Kucetyiswa ukuba unikezelo lwamandla lunokunqunyulwa xa umbane uhlawuliswa ukuya kuma-90% ngokuhambelana nomboniso wemitha yamandla, kuba ukutshaja ukuya kwi-100% kuya kwandisa isizukulwana sobushushu kwaye iingozi zomngcipheko wokhuseleko ziya kwanda kakhulu, ngoko ke umbane unokunqunyulwa xa uhlawuliswa ukuya kuma-90% ukuphepha iziphumo ezibi zenkqubo kwibhetri. Iibhetri ze-lithium iron phosphate zinokuhlawuliswa ukuya kwi-100%, kodwa kufuneka kuqatshelwe ukuba umbane kufuneka unqunyulwe ngexesha emva kokuba uhlawulwe ngokupheleleyo ukuphepha ukutshaja.
