Bill Gates: Mathirakitala amagetsi, ndege zonyamula anthu? Iwo mwina sadzakhala konse yankho.

Nthawi zambiri m'mbiri ya Microsoft, pamene Bill Gates adalengeza kuti chinachake sichili bwino, anali akugwira ntchito mofatsa. Chifukwa chake ngati Gates akuti ndege zamagetsi kapena magalimoto sizipanga zomveka ndipo akugulitsa ndalama zoyambira zolimba kumbuyo, zikuwoneka zosangalatsa.

Kuyenda molemera kwamtsogolo - magetsi kapena biofuel?

Bill Gates ndithudi si katswiri wa batri ndi magalimoto amagetsi. Ndipo komabe adayikapo ndalama ku QuantumScape, yomwe ili ndi ma cell olimba a electrolyte. Mwa zina, ndalama zake zidzagwiritsidwa ntchito poyambira katundu wamtengo wapatali wa madola 3,3 biliyoni a US (ofanana ndi 12,4 biliyoni zloty).

Volkswagen ndi Continental alinso ndi magawo ku QuantumScape.

Ndizochepa zomwe zimadziwika za maselo oyambilira. Kampaniyo imati amagwiritsa ntchito electrolyte yolimba ndipo alibe anode yapamwamba. Zoonadi, maselo amodzi a electrode samamveka. Izi "palibe anode" amatanthauza "palibe anode prefabricated", graphite kapena graphite silicon wosanjikiza. Anode imapangidwa pamphambano ya electrode yachiwiri ndipo imakhala ndi maatomu a lithiamu omwe amatulutsidwa ndi cathode panthawi yamalipiro.

Mwachidule: tikuchita ndi lithiamu zitsulo, lithiamu zitsulo maselo:

Palibe kukonzekera kwa anode komwe kumafunikira ku fakitale kumatanthauza kutsitsa mtengo wopangira... Izi ziyeneranso kumasuliridwa ku kuchuluka kwa maselongakhale chiwerengero cha maatomu a lithiamu pa cathode ndi chimodzimodzi monga mu selo la lithiamu-ion classical. Chifukwa chiyani?

Ndizosavuta: popanda graphite anode, selo ndi yopepuka komanso yocheperako ndipo imatha kusunga ndalama zomwezo (= chifukwa tinkaganiza kuti ma atomu a lithiamu anali ofanana). Chifukwa chake, ma gravimetric (odalira misa) ndi kuchuluka (kutengera voliyumu) ​​kuchuluka kwa mphamvu zama cell kumawonjezeka.

Maselo ang'onoang'ono omwe amasunga mtengo womwewo amalola kuti maselo ambiri alowe mu chipinda cha batri, zomwe zikutanthauza mphamvu ya batri yapamwamba. Izi ndi zomwe QuantumScape imalonjeza.

Pakadali pano, a Bill Gates amakhulupirira kuti zombo zonyamula katundu zamagetsi, ndege zonyamula anthu ndi magalimoto mwina sizingakhale yankho lothandiza chifukwa cha kulemera kwakukulu kwa mabatire. Popeza alipo ambiri, DAF yawonjezera thirakitala yake mpaka makilomita oposa 200, ndikuwonjezera mphamvu ya batri mpaka 315 kWh:

> DAF yakulitsa mtundu wa CF Electric kupitilira ma kilomita 200.

Tikhoza kuwerengera izo mosavuta kukulitsa mtunda wa makilomita 800 kudzafuna kugwiritsa ntchito ma cell oposa 1,1 MWh olemera matani osachepera 7-8.... Kwa Gates, uku ndi kufooka ndipo, monga amanenera, vuto losagonjetseka.

Komabe, anthu omwe ali ndi mutuwu amatsutsana ndi izi. Elon Musk akuganiza kuti ndege zamagetsi zimakhala zomveka tikafika 0,4 kWh / kg. Lero tikuyandikira 0,3 kWh / kg, ndipo oyambitsa ena amati afika kale 0,4 kWh / kg:

> Imec: tili ndi maselo olimba a electrolyte, kachulukidwe kamphamvu 0,4 kWh / lita, ndalama 0,5C

Koma woyambitsa nawo Microsoft akukhulupirira kuti biofuel ikhala njira yabwinoko pamagalimoto akuluakulu, olemera. Mwina mafuta amagetsi, ma hydrocarbon omwe amachokera kumadzi ndi mpweya woipa kuchokera kumlengalenga (gwero). Ndi chifukwa chake adaganiza zopanga ndalama kukampani yomwe imachita ndi ma cell olimba a electrolyte?

Zolemba mkonzi www.elektrowoz.pl: Maulalo a QuantumScape ndi mutu wosangalatsa. Tidzabweranso kwa iwo pambuyo pake 🙂
