U-Penn: Sinendlela eshesha kakhulu yokushaja amaseli e-LiFePO4: +2 400 km / h. Ukuwohloka? I-Mileage 3,2 million km!
Okuqukethwe
Ososayensi basePennsylvania State University bathole indlela yokushaja amabhethri asheshayo asuselwa kumaseli e-lithium iron phosphate (LFP, LiFePO4). Ngenxa yomklamo ofanele, bayakwazi ukumboza ibanga elingamakhilomitha angama-400 ngemizuzu eyi-10 (+2 km / h), elihambisana namandla okushaja angaba ngu-400 C.
Amaseli e-LFP njengethuba lezimoto zikagesi ezishibhile nezisebenza kahle
Uhlu lokuqukethwe
- Amaseli e-LFP njengethuba lezimoto zikagesi ezishibhile nezisebenza kahle
- I-Nissan Leaf II njenge-Porsche: ukusheshisa okuhle kakhulu, ukushaja okusheshayo
Sibhale izikhathi eziningi mayelana nezinzuzo zamaseli e-LFP: ishibhile kune-NCA/NCM - futhi athembisa kahle uma kuziwa ekuncishisweni okwengeziwe kwentengo - aphephile, ehlisa isithunzi, futhi avumela imijikelezo yokushaja egcwele ngaphandle kokuthinta umthamo. ukucekelwa phansi. Ububi bazo amandla athile aphansi kanye nekhono elincane lokusheshisa ukushaja. Kubonakala sengathi kuningi okwenzekile muva nje kokubili kokuqala (isixhumanisi esingezansi) nokwesibili (okunye okuqukethwe kwe-athikili).
> I-Guoxuan: Sifinyelele ku-0,212 kWh / kg kumaseli ethu e-LFP, siya phambili. Lawa amasayithi e-NCA / NCM!
Abacwaningi basePennsylvania bathole indlela ukwanda kwamandla ebhethri okushaja ngokusekelwe kumaseli e-LFP... Nokho, basonga amaseli ngephepha elincanyana le-nickel elixhunywe kwelinye lama-electrode ebhethri. Lapho ukushaja kuqala, amandla kagesi ageleza kuwo. I-foil ishisa amaseli (ngaphakathi kwebhethri) kuya ku-60 degrees Celsius. futhi ngemva kwalokho kuphela lapho inqubo yokugcwalisa amandla iqala.
Njengoba ukushisa akuveli ngaphakathi kweseli, kodwa kuwumphumela we-heater eyengeziwe, ayikho inkinga ebonakalayo ngokukhula kwe-lithium dendrite.
Abacwaningi bathi ngamaseli ashisayo bazokwazi ukugcwala Ibanga lokuhamba ngomkhumbi lamakhilomitha angama-400 ngemizuzu eyi-10 (+2 400 km/h)... Abakwazi ukuziqhayisa ngamavelu athile wamandla wokushaja, kodwa kucatshangelwa ukuthi umthamo webhethri oyifunayo njengamanje kufanele uhambisane nobubanzi bamakhilomitha angama-400-500, amandla okushaja kufanele abe ngu-4,8-6 C. Uma ishajwa - isanamaseli ashisayo - ithembisa ukuthi izokwazi ukukhiqiza amandla angu-300kW kusuka ku-40kWh (7,5°C, umthombo webhethri).
Ukushaja kwamandla aphezulu kumele kuphephe ngokuphelele kumaseli achaziwe. Ososayensi bayathembisa kufika kumakhilomitha ayizigidi ezingu-3,2, okungukuthi, ngebanga elingenhla (400-500 km) impilo yesevisi 6-400 imijikelezo yokusebenza egcwele.
I-Nissan Leaf II njenge-Porsche: ukusheshisa okuhle kakhulu, ukushaja okusheshayo
Ukuze uqonde ukuthi wonke amapharamitha angenhla asho ukuthini, ake siwahlelele emotweni yokuqala onqenqemeni. Cabanga nje I-Nissan Leafa II enebhethri engenhla... Ngomthamo [sewonke] ongu-40 kWh, ibhethri lizokwazi ukuletha amandla afinyelela kwangu-300 kW (408 hp), okuthi, noma lilahlekile, linikeze cishe ama-250 kW (340 hp) emasondweni.
Imoto enjalo, uma ikwazi ukugcina ukudonsa, ingaba nayo ukusebenza okufana nePorsche Boxster futhi kuzovumela ukugcwalisa kabusha amandla afinyelela ku-240 kW. Futhi ibhethri elifudumalayo ngenkathi ushayela lingaba inzuzo, hhayi ukonakala, ngoba ngeke lidinge ukushisisa kabusha ukuze lisebenze kahle kakhulu.
