Bill Gates: Electric tsheb laij teb, neeg nrog caij dav hlau? Tej zaum lawv yuav tsis yog qhov kev daws teeb meem.

Feem ntau hauv Microsoft keeb kwm, thaum Bill Gates categorically tshaj tawm tias ib yam dab tsi tsis ncaj ncees lawm, nws twb tau ua haujlwm rau nws. Yog li yog tias Gates hais tias cov dav hlau hluav taws xob lossis cov tsheb thauj khoom tsis ua rau muaj kev nkag siab thiab tab tom nqis peev hauv kev pib ua haujlwm hauv lub xeev tom qab, qhov ntawd yog qhov nthuav.

Kev thauj hnyav ntawm lub neej yav tom ntej - hluav taws xob lossis biofuel?

Bill Gates yeej tsis yog lub roj teeb thiab hluav taws xob tshwj xeeb tsheb. Thiab tseem nws tau nqis peev hauv QuantumScape, uas khav theeb cov khoom siv hluav taws xob. Ntawm lwm yam, nws cov nyiaj yuav raug siv rau cov khoom lag luam debut ntawm qhov pib muaj nqis 3,3 billion US dollars (sib npaug rau 12,4 billion zlotys).

Volkswagen thiab Continental kuj muaj ceg txheem ntseeg hauv QuantumScape.

Me me tsis paub txog kev pib-tsim hlwb. Lub tuam txhab hais tias lawv siv cov khoom siv electrolyte thiab tsis muaj cov anode classic. Ntawm chav kawm, ib leeg electrode hlwb tsis ua rau kev nkag siab. Qhov no "tsis muaj anode" txhais tau tias "tsis muaj prefabricated anode", graphite lossis graphite silicon txheej. Lub anode yog tsim nyob rau ntawm qhov sib txuas ntawm ob electrode thiab muaj lithium atoms tso tawm los ntawm cathode thaum lub sij hawm them nyiaj.

Hauv luv: peb tab tom cuam tshuam nrog lithium hlau, lithium hlau hlwb:

Tsis muaj anode npaj yuav tsum tau ntawm lub Hoobkas txhais tau tias qis dua cov nqi tsim khoom... Qhov no kuj yuav tsum tau muab txhais rau muaj peev xwm ntawm tes ntau duaTxawm hais tias tus naj npawb ntawm lithium atoms ntawm lub cathode yog tib yam li nyob rau hauv classical lithium-ion cell. Vim li cas?

Nws yog qhov yooj yim: tsis muaj graphite anode, lub xov tooj ntawm tes yog sib dua thiab nyias thiab tuaj yeem khaws cov nqi tib yam (= vim peb xav tias cov lej ntawm lithium atoms yog tib yam). Yog li, lub gravimetric (ntau-dependent) thiab bulk (volume-dependent) cell zog densities nce.

Cov hlwb me me uas khaws cov nqi tib yam tso cai rau ntau lub hlwb kom haum rau hauv lub roj teeb, uas txhais tau tias muaj peev xwm ntau dua. Qhov no yog raws nraim li QuantumScape cog lus.

Lub caij no, Bill Gates ntseeg tias cov nkoj thauj khoom hluav taws xob, cov neeg caij dav hlau thiab cov tsheb thauj khoom zoo li yuav tsis muaj txiaj ntsig zoo vim tias lub roj teeb hnyav hnyav. Txij li thaum muaj ntau ntawm lawv, DAF tau nce qhov ntau ntawm nws lub tsheb laij teb mus rau ntau tshaj 200 kilometers, nce lub roj teeb muaj peev xwm mus txog 315 kWh:

> DAF tau txuas ntxiv CF Electric's ntau tshaj 200 mais.

Peb tau yooj yim xam qhov ntawd nce qhov deb mus rau 800 mais yuav xav tau kev siv ntau tshaj 1,1 MWh ntawm cov hlwb uas hnyav li 7-8 tons.... Rau Gates, qhov no yog qhov tsis muaj zog thiab, raws li nws hais, yog ib qho teeb meem uas tsis tuaj yeem cuam tshuam.

Txawm li cas los xij, cov neeg hais txog lub ncauj lus no tsis pom zoo rau qhov no. Elon Musk xav tias lub dav hlau hluav taws xob ua rau kev txiav txim siab thaum peb ntaus 0,4 kWh / kg. Niaj hnub no peb tab tom mus txog 0,3 kWh / kg, thiab qee qhov pib hais tias lawv tau mus txog 0,4 kWh / kg:

> Imec: peb muaj cov khoom siv hluav taws xob electrolyte, lub zog ceev 0,4 kWh / liter, them 0,5C

Tab sis Microsoft co-founder ntseeg tias biofuels yuav yog lwm txoj hauv kev zoo dua rau cov tsheb loj thiab hnyav. Tej zaum hluav taws xob roj, hydrocarbons muab tau los ntawm dej thiab carbon dioxide los ntawm qhov chaw (qhov chaw). Yog vim li cas nws thiaj txiav txim siab los nqis peev hauv lub tuam txhab uas cuam tshuam nrog cov khoom siv hluav taws xob electrolyte?

Editor's note www.elektrowoz.pl: links QuantumScape yog ib lub ntsiab lus nthuav. Peb mam li rov qab rau lawv tom qab :)
