Ibhethri elinamandla libizwa ngokuthi inhliziyo yemoto kagesi; uhlobo, izinto ezisetshenziswayo, umthamo, ukusebenza kokuphepha, njll. kwebhethri lemoto kagesi sekuyizinto ezibalulekile "zokulinganisa" kanye "namapharamitha" okulinganisa imoto kagesi. Njengamanje, izindleko zebhethri lemoto kagesi ngokuvamile zingama-30%-40% emoto yonke, okungashiwo ukuthi iyisengezo esiyinhloko!
Njengamanje, amabhethri kagesi asetshenziswa kakhulu ezimotweni zikagesi emakethe ngokuvamile ahlukaniswe izinhlobo ezimbili: amabhethri e-ternary lithium kanye namabhethri e-lithium iron phosphate. Okulandelayo, ake ngihlaziye kafushane umehluko nezinzuzo kanye nokungalungi kwamabhethri amabili:
1. Izinto ezahlukene:
Isizathu sokuthi ibizwa ngokuthi "i-ternary lithium" kanye ne-"lithium iron phosphate" ngokuyinhloko sibhekisela ezintweni zamakhemikhali "zezinto ze-electrode ezinhle" zebhethri lamandla;
"I-lithium ye-Ternary":
Izinto ze-cathode zisebenzisa izinto ze-lithium nickel cobalt manganate (Li(NiCoMn)O2) ze-ternary cathode zamabhethri e-lithium. Lezi zinto zihlanganisa izinzuzo ze-lithium cobalt oxide, i-lithium nickel oxide kanye ne-lithium manganate, zakha uhlelo lwe-eutectic lwezigaba ezintathu lwezinto ezintathu. Ngenxa yomphumela we-ternary synergistic, ukusebenza kwayo okuphelele kungcono kunanoma iyiphi inhlanganisela eyodwa.
"I-Lithium iron phosphate":
ibhekisela kumabhethri e-lithium-ion asebenzisa i-lithium iron phosphate njengento ye-cathode. Izici zayo ukuthi ayinazo izakhi zensimbi eziyigugu njenge-cobalt, intengo yezinto zokusetshenziswa iphansi, futhi izinsiza ze-phosphorus nensimbi ziningi emhlabeni, ngakho ngeke kube nezinkinga zokutholakala.
isifinyezo
Izinto ze-lithium ze-ternary azitholakali kalula futhi ziyanda ngokuthuthukiswa okusheshayo kwezimoto zikagesi. Amanani azo aphezulu futhi anqunyelwe kakhulu yizinto zokusetshenziswa eziphezulu. Lokhu kuyisici se-lithium ye-ternary okwamanje;
I-lithium iron phosphate, ngoba isebenzisa isilinganiso esiphansi sezinsimbi ezingavamile/eziyigugu futhi ikakhulukazi ishibhile futhi iyinsimbi eningi, ishibhile kunebhethri le-ternary lithium futhi ayithinteki kakhulu yizinto zokusetshenziswa ezingenhla. Lesi yisici sayo.
2. Ubuningi bamandla obuhlukene:
"Ibhethri le-lithium le-Ternary": Ngenxa yokusetshenziswa kwezinto zensimbi ezisebenzayo kakhulu, ubukhulu bamandla bamabhethri e-lithium e-ternary ajwayelekile ngokuvamile buyi-(140wh/kg~160 wh/kg), okuphansi kunokwamabhethri e-ternary anesilinganiso esiphezulu se-nickel (160 wh/kg).～180 wh/kg); isisindo esithile samandla singafinyelela ku-180Wh-240Wh/kg.
"I-Lithium iron phosphate": Ubuningi bamandla ngokuvamile bungu-90-110 W/kg; amanye amabhethri e-lithium iron phosphate amasha, njengamabhethri e-blade, anobukhulu bamandla obufika ku-120W/kg-140W/kg.
isifinyezo
Inzuzo enkulu kakhulu "yebhethri le-ternary lithium" kune-"lithium iron phosphate" amandla ayo aphezulu kanye nesivinini sokushaja okusheshayo.
3. Ukuguquguquka kwezinga lokushisa okuhlukile:
Ukumelana nokushisa okuphansi:
Ibhethri le-lithium eliyi-ternary: Ibhethri le-lithium eliyi-ternary lisebenza kahle kakhulu ekushiseni okuphansi futhi lingagcina cishe u-70% ~ 80% womthamo webhethri ojwayelekile ku--20°C.
I-lithium iron phosphate: Ayimelani namazinga okushisa aphansi: Uma izinga lokushisa lingaphansi kuka--10°C,
Amabhethri e-lithium iron phosphate abola ngokushesha kakhulu. Amabhethri e-lithium iron phosphate angagcina cishe u-50% kuya ku-60% womthamo webhethri ojwayelekile ku--20°C.
isifinyezo
Kunomehluko omkhulu ekuzivumelaniseni nokushisa phakathi "kwebhethri le-lithium le-ternary" kanye "ne-lithium iron phosphate"; "i-lithium iron phosphate" imelana kakhulu nokushisa okuphezulu; kanti "ibhethri le-lithium le-ternary elimelana nokushisa okuphansi" linempilo engcono yebhethri ezindaweni ezisenyakatho noma ebusika.
4. Izikhathi zokuphila ezahlukene:
Uma umthamo/umthamo wokuqala osele = 80% usetshenziswa njengendawo yokugcina yokuhlola, hlola:
Amabhethri e-lithium iron phosphate aphila isikhathi eside kunamabhethri e-lead-acid kanye namabhethri e-ternary lithium. "Isikhathi eside kakhulu" samabhethri ethu e-lead-acid afakwe emotweni cishe izikhathi ezingu-300 kuphela; ibhethri le-ternary lithium lingahlala izikhathi ezifika ku-2,000 ngokombono, kodwa uma lisetshenziswa ngempela, amandla azobola abe ngu-60% ngemva kwezikhathi ezingaba ngu-1,000; futhi impilo yangempela yamabhethri e-lithium iron phosphate ingu-2000, kusekhona amandla angu-95% ngalesi sikhathi, futhi impilo yomjikelezo wayo womqondo ifinyelela izikhathi ezingaphezu kuka-3000.
isifinyezo
Amabhethri kagesi ayiyona nto evelele kwezobuchwepheshe yamabhethri. Zombili izinhlobo zamabhethri e-lithium zihlala isikhathi eside. Ngokwethiyori, isikhathi sokuphila sebhethri le-lithium eliyi-ternary siyimijikelezo yokushaja nokukhipha engu-2,000. Ngisho noma singayishaja kanye ngosuku, ingahlala iminyaka engaphezu kwemi-5.
5. Amanani ahlukile:
Njengoba amabhethri e-lithium iron phosphate engenazo izinto zensimbi eziyigugu, izindleko zezinto zokusetshenziswa zingancishiswa kakhulu. Amabhethri e-lithium e-Ternary asebenzisa i-lithium nickel cobalt manganate njengezinto ze-electrode ezinhle kanye ne-graphite njengezinto ze-electrode ezimbi, ngakho-ke izindleko zibiza kakhulu kunezamabhethri e-lithium iron phosphate.
Ibhethri le-ternary lithium lisebenzisa kakhulu izinto ze-ternary cathode ze-"lithium nickel cobalt manganate" noma "lithium nickel cobalt aluminate" njenge-electrode enhle, ikakhulukazi isebenzisa usawoti we-nickel, usawoti we-cobalt, nosawoti we-manganese njengezinto zokusetshenziswa. "Isici se-cobalt" kulezi zinto ezimbili ze-cathode siyinsimbi eyigugu. Ngokusho kwedatha evela kumawebhusayithi afanele, intengo yasekhaya yensimbi ye-cobalt ingu-413,000 yuan/ton, futhi ngokuncipha kwezinto, intengo iyaqhubeka nokwenyuka. Njengamanje, izindleko zamabhethri e-ternary lithium ziyi-0.85-1 yuan/wh, futhi okwamanje iyanda ngokufunwa kwemakethe; izindleko zamabhethri e-lithium iron phosphate angenazo izakhi zensimbi eyigugu zingama-yuan angu-0.58-0.6 kuphela/wh.
isifinyezo
Njengoba i-"lithium iron phosphate" ingenazo izinsimbi eziyigugu njenge-cobalt, intengo yayo iphindwe izikhathi ezingu-0.5-0.7 kuphela kuneyamabhethri e-ternary lithium; intengo eshibhile iyinzuzo enkulu ye-lithium iron phosphate.
Fingqa
Isizathu sokuthi izimoto zikagesi zichume eminyakeni yamuva nje futhi zimelela isiqondiso sesikhathi esizayo sokuthuthukiswa kwezimoto, okunikeza abathengi ulwazi olungcono kakhulu, ikakhulukazi ngenxa yentuthuko eqhubekayo yobuchwepheshe bebhethri lamandla.
Isikhathi sokuthunyelwe: Okthoba-28-2023
