Cov kws tshawb fawb tau tsim cov hlwb sodium-ion (Na-ion) nrog cov khoom electrolyte • ELECTRIC CARS
Cov kws tshawb fawb los ntawm University of Austin (Texas, USA) tau tsim cov hlwb Na-ion nrog cov khoom siv electrolyte. Lawv tseem tsis tau npaj txhij rau kev tsim khoom, tab sis lawv zoo li kev cog lus: lawv zoo ib yam li cov lithium-ion hlwb, tiv taus ntau pua lub voj voog ua haujlwm thiab siv cov khoom pheej yig thiab pheej yig - sodium.
Asphalt, graphene, silicon, sulfur, sodium - cov tshuaj thiab cov khoom no yuav ua rau nws muaj peev xwm txhim kho cov khoom hluav taws xob yav tom ntej. Lawv muaj ib yam zoo sib xws: lawv kuj tau yooj yim muaj (nrog rau qhov tshwj xeeb ntawm graphene) thiab cog lus ua haujlwm zoo ib yam li, thiab tej zaum yuav zoo dua yav tom ntej, lithium.
Ib lub tswv yim nthuav yog hloov lithium nrog sodium. Ob lub ntsiab lus muaj nyob rau tib pab pawg ntawm cov hlau alkali, ob qho tib si sib npaug, tab sis sodium yog thib rau ntau tshaj plaws nyob rau hauv lub ntiaj teb crust thiab peb tuaj yeem tau txais nws pheej yig. Hauv Na-ion hlwb tsim nyob rau hauv Texas, lithium nyob rau hauv anode yog hloov los ntawm sodium, thiab flammable electrolytes yog hloov los ntawm cov khoom sulfur electrolytes. (ib qhov chaw).
Thaum xub thawj, siv cov ceramic cathode, tab sis thaum lub sijhawm ua haujlwm (kev lees txais / nqi hloov pauv) nws hloov loj thiab tawg. Yog li ntawd, nws tau hloov pauv nrog cov cathode hloov tau los ntawm cov khoom siv organic. Lub cell tsim nyob rau hauv txoj kev no ua haujlwm yam tsis muaj qhov ua tsis tiav rau ntau tshaj 400 lub sijhawm them / tawm, thiab cathode tau txais lub zog ceev ntawm 0,495 kWh / kg (tus nqi no yuav tsum tsis txhob tsis meej pem nrog lub zog ceev ntawm tag nrho cov xov tooj ntawm tes lossis roj teeb).

Tom qab kev txhim kho ntxiv ntawm cathode, nws muaj peev xwm mus txog qib 0,587 kWh / kg, uas kwv yees li sib haum rau cov txiaj ntsig tau txais ntawm cathodes ntawm lithium-ion hlwb. Tom qab 500 lub voj voog, lub roj teeb muaj peev xwm tuav tau 89 feem pua ntawm nws lub peev xwm.uas kuj sib haum mus rau qhov tsis muaj zog [tsis muaj zog] Li-ion hlwb.
Na-ion hlwb ua haujlwm ntawm qhov hluav taws xob qis dua lithium-ion hlwb, yog li lawv tuaj yeem siv rau lub zog hluav taws xob portable. Txawm li cas los xij, pab pawg Austin kuj tau txiav txim siab tsiv mus rau qhov hluav taws xob ntau dua kom cov hlwb tuaj yeem siv rau hauv tsheb hluav taws xob. Vim li cas? Ib qho ntawm cov tsis tseem ceeb ntawm lub tsheb yog nws lub zog, thiab nws ncaj qha nyob ntawm lub zog ntawm qhov tam sim no thiab qhov hluav taws xob ntawm cov electrodes.
Nws tsim nyog ntxiv tias John Goodenough, tus tsim ntawm lithium-ion hlwb, los ntawm University of Austin.
