Bill Gates: Ogandaganda bakagesi, izindiza zabagibeli? Cishe ngeke babe yisixazululo.
Imvamisa emlandweni weMicrosoft kwenzeka ukuthi lapho uBill Gates ememezela ngokusobala ukuthi kukhona okungahambi kahle, wayesesebenza kuso ngokuthula. Ngakho-ke uma uGates ethi izindiza zikagesi noma amaloli awawenzi umqondo futhi utshala imali ekuqaliseni isimo esiqinile ngemuva, lokho kuzwakala kuthakazelisa.
Ukuthuthwa okusindayo kwekusasa - ugesi noma i-biofuel?
UBill Gates akayena neze uchwepheshe webhethri nemoto kagesi. Futhi nokho watshala imali ku-QuantumScape, enamaseli aqinile e-electrolyte. Phakathi kwezinye izinto, imali yakhe izosetshenziselwa ukuqala kwesitoko sokuqala esibiza ama-dollar ayizigidi eziyizinkulungwane ezingu-3,3 (okulingana nama-zloty ayizigidi eziyizinkulungwane ezingu-12,4).
KwaVolkswagen kanye neContinental nabo banamasheya kuQuantumScape.
Kuncane okwaziwayo ngamaseli athuthukiswe ukuqalisa. Inkampani ithi isebenzisa i-electrolyte eqinile futhi ayinayo i-anode yakudala. Yiqiniso, amaseli e-electrode eyodwa awawenzi umqondo. Lokhu "akukho anode" kusho "ayikho i-anode eyenziwe ngaphambili", ungqimba lwe-graphite noma i-graphite silicon. I-anode yakheka lapho kuhlangana khona i-electrode yesibili futhi iqukethe ama-athomu e-lithium akhishwe yi-cathode ngesikhathi sokushaja.
Ngamafuphi: sisebenzelana nensimbi ye-lithium, amaseli ensimbi e-lithium:
Akukho ukulungiswa kwe-anode okudingekayo endaweni yemboni izindleko zokukhiqiza eziphansi... Lokhu kufanele futhi kuhunyushwe ngokuthi umthamo weseli ophezulungisho noma inani lama-athomu e-lithium ku-cathode lifana neseli ye-lithium-ion yakudala. Kungani?
Kulula: ngaphandle kwe-graphite anode, iseli lilula futhi lincane futhi lingagcina inkokhiso efanayo (= ngoba sicabange ukuthi inani lama-athomu e-lithium liyafana). Ngakho-ke, i-gravimetric (encike ngobuningi) kanye nenqwaba (encike kwivolumu) ukuminyana kwamandla kwamaseli kuyanda.
Amaseli amancane agcina ukushajwa okufanayo avumela amaseli engeziwe ukuthi alingane ekhomishini yebhethri, okusho ukuthi umthamo webhethri uphakeme. Yilokhu kanye iQuantumScape ekuthembisayo.
Khonamanjalo, uBill Gates ukholelwa ukuthi imikhumbi yezimpahla zikagesi, izindiza zabagibeli namaloli cishe ngeke kube yisixazululo esisebenzayo ngenxa yesisindo esinzima samabhethri. Njengoba ziningi, i-DAF inyuse ibanga likagandaganda wayo yaba ngaphezu kwamakhilomitha angama-200, ikhulisa amandla ebhethri ku-315 kWh:
> I-DAF inwebise uhla lwe-CF Electric lwaba ngaphezu kwamakhilomitha angama-200.
Singakubala kalula lokho ukwandisa ububanzi bufike kumakhilomitha angu-800 kuzodinga ukusetshenziswa kwamaseli angaphezu kuka-1,1 MWh anesisindo esingamathani angu-7-8.... KuGates, lokhu kuwubuthakathaka futhi, njengoba esho, inkinga engenakuxazululeka.
Nokho, abantu ababhekene nalesi sihloko abavumelani nalokhu. U-Elon Musk ucabanga ukuthi izindiza zikagesi zinengqondo lapho sishaya u-0,4 kWh / kg. Namuhla sisondela ku-0,3 kWh / kg, futhi ezinye iziqalo zithi sezivele zifinyelele ku-0,4 kWh / kg:
> I-Imec: Sinamaseli e-electrolyte aqinile, ukuminyana kwamandla 0,4 kWh / ilitha, ukushaja 0,5C
Kodwa umsunguli we-Microsoft ukholelwa ukuthi ama-biofuels azoba enye indlela engcono yezimoto ezinkulu, ezinzima. Kungenzeka amafutha kagesi, ama-hydrocarbon atholakala emanzini kanye ne-carbon dioxide emkhathini (umthombo). Yingakho anquma ukutshala imali enkampanini esebenza ngamaseli e-electrolyte aqinile?
Inothi lomhleli www.elektrowoz.pl: Izixhumanisi ze-QuantumScape ziyisihloko esithokozisayo. Sizobuyela kubo kamuva 🙂
