IBM tau tsim cov lithium-ion tshiab uas tsis muaj cobalt thiab npib tsib xee. Kev thauj khoom mus txog 80% hauv 5 feeb ntau dua 0,8 kWh / l!
Tshiab lithium-ion hlwb los ntawm IBM tshawb fawb lab. Lawv siv "peb cov ntaub ntawv tshiab" thiab lub roj teeb ua los ntawm lawv tuaj yeem them txog 80 feem pua hauv tsawg dua 5 feeb. Lawv tsis siv kim cobalt lossis npib tsib xee, uas tuaj yeem txo tus nqi ntawm cov tsheb fais fab yav tom ntej.
Cov ntsiab lus tshiab los ntawm IBM: pheej yig dua, zoo dua, ua haujlwm zoo dua
twb Xyoo 2016, cov tuam txhab ntawm tes thiab roj teeb tau noj 51 feem pua ntawm lub ntiaj teb cobalt ntau lawm.... Qee cov kws tshawb fawb xav tias qhov kev txaus siab ntau ntxiv hauv cov tsheb hluav taws xob yuav tsav tus nqi ntawm cov hlau vim tias nws muaj tsawg. Thiab qhov no txawm tias muaj ntau lub tuam txhab ua haujlwm los tshem tawm cov khoom no los ntawm cov roj teeb lithium-ion.
Kev nce nqi cobalt ua rau qeeb qeeb ntawm cov nqi tsheb fais fab. Lawv yuav nyob ze rau qib tam sim no:
> MIT tsab ntawv ceeb toom: Lub tsheb hluav taws xob yuav tsis poob rau hauv tus nqi sai li koj xav. Ntau dua hauv 2030
lub caij no IBM cell cathodes tsis muaj cobalt, nickel thiab hnyav hlau.thiab cov khoom siv hauv lawv tuaj yeem muab rho tawm los ntawm cov dej hiav txwv (qhov chaw).
Raws li a tus nqi ntawm lub roj teeb hnub no yog kwv yees li 1/3 tus nqi ntawm lub tsheb fais fab., qhov pheej yig dua cov ntsiab lus uas tsim cov hlwb, qhov pheej yig dua tus nqi kawg ntawm lub tsheb fais fab yog qis dua.

Tsis tas li ntawd, lawv siv nws high flash point kua electrolytesuas tuaj yeem yog qhov tseem ceeb thaum muaj xwm txheej. Ntxiv mus, niaj hnub electrolytes yog heev flammable.
IBM hais tias nws tau sim lub roj teeb los ntawm nws cov hlwb teeb tsa los txhawb lub zog siab. Nws ua nws them li 80 feem pua hauv tsawg dua 5 feeb... Qhov no yuav txhais tau tias nres ntawm qhov chaw nres tsheb them rau tib lub sij hawm li refueling.
Cov chaw tsim khoom cog lus tias cov hlwb tshiab yuav tsim cov roj teeb uas ua tau zoo dua li cov lithium-ion tam sim no. Piv txwv li, lawv yuav muab lub zog ntau dua 10 kW ib liter ntawm roj teeb (10 kW / l) thiab twb muaj peev xwm ncav cuag lub zog ceev ntawm ntau tshaj 0,8 kWh / l.
Los ntawm kev sib piv, CATL khav theeb xyoo no tias tiam tshiab ntawm lithium-ion hlwb nrog nickel-nplua nuj cathode tau mus txog. 0,7 kWh / l (thiab 0,304 kWh / kg). Thiab TeraWatt thov kom tau tsim cov khoom siv hluav taws xob electrolyte nrog lub zog ntom ntom ntawm 1,122 kWh / L (thiab 0,432 kWh / kg):
> TeraWatt: Peb muaj cov khoom siv hluav taws xob electrolyte nrog lub zog tshwj xeeb ntawm 0,432 kWh / kg. Muaj los ntawm 2021
Kev tshawb fawb ntawm tes tau ua los ntawm IBM hauv kev koom tes nrog Daimler, tus tswv ntawm Mercedes-Benz hom.
Intro Diam duab: sab laug sab laug - sab hauv ntawm lub chaw tshawb fawb, sab xis sab xis - cov hlwb thaum kuaj, hauv qab sab laug - cell chemistry encapsulated hauv classic ca "cov tshuaj" hauv lub tshuab kuaj roj teeb (c) IBM
Editor's Note www.elektrowoz.pl: 2016 Cobalt Consumption data from the Cobalt Institute. Peb hais rau lawv vim hais tias nyob rau hauv tsab xov xwm "Tag nrho them" rau cobalt qhov teeb meem yog me ntsis exaggerated. Txawm hais tias nws yog qhov tseeb tias cobalt kuj tseem siv los ua cov roj crude (= roj ntau lawm).
Qhov no yuav txaus siab rau koj:
