Australia txhim kho cov roj teeb ua hluav taws xob proton nrog lub zog sib zog ntau dua li cov roj teeb lithium
Twb tau muaj ntau lub tsheb siv roj hluav taws xob uas muaj roj hydrogen nyob rau tom khw, tab sis cov kws tshawb fawb los ntawm Royal Melbourne Institute of Technology hauv tebchaws Australia tau hais txog lub tswv yim “roj teeb proton”. Yog tias thev naus laus zis tuaj yeem nthuav dav, nws tuaj yeem nthuav dav kev nthuav dav ntawm cov tshuab hluav taws xob uas siv hluav taws xob thiab ua rau nws muaj peev xwm hloov pauv tau rau cov roj teeb lithium-ion.energy cia cov nqi roj teeb, Tau kawg, tsis zoo li cov tshuab siv hluav taws xob hydrogen uas tsim, khaws, thiab rov qab hydrogen, cov khoom siv proton ua haujlwm ntau dua li lub roj teeb hauv kev nkag siab ib txwm muaj.

Associate Professor JohnAndrews thiab nws “proton flow battery system” ua pov thawj ua ntej ntawm lub tswvyim tsab

Cov txheej txheem ib txwm siv dej electrolyzes dej thiab sib cais hydrogen thiab oxygen, thiab tom qab ntawd khaws lawv ntawm ob qho kawg ntawm roj teeb lithium-roj. Thaum hluav taws xob tab tom yuav tshwm tuaj, hydrogen thiab oxygen raug xa mus rau lub tshuab hluav taws xob rau tshuaj lom neeg.

Txawm li cas los xij, kev ua haujlwm ntawm cov roj av proton sib txawv-vim tias nws sib xyaw cov hlau hydride cia hluav taws xob ntawm cov thim rov qab hloov pauv proton membrane (PEM) roj-siv cov roj teeb lithium.

Qhov loj ntawm cov cuab yeej no yog 65x65x9 mm

Raws li John Andrews, tus kws tshawb fawb tseem ceeb ntawm txoj haujlwm no thiab koom nrog xibfwb ntawm Department of Mechanical and Manufacturing Engineering ntawm Royal Melbourne Institute of Technology (RMIT) Lub Tsev Kawm Ntawv ntawm Aerospace Engineering, “Lub hauv paus tseem ceeb rau kev hloov pauv tshiab nyob rau hauv cov roj rov qab siv tau lithium roj teeb nrog kev khaws cia hluav taws xob. Peb tau tshem tawm tag nrho cov proton rau roj. Tag nrho cov txheej txheem, thiab cia cov hydrogen nkag mus rau hauv lub xeev ruaj khov. “

Cov kab ke hloov pauv khaws cov khoom siv hluav taws xob ntawm hydrogen thiab tom qab ntawd “rov tsim dua” hluav taws xob

Cov txheej txheem them nqi tsis suav nrog cov txheej txheem decomposing dej rau hauv hydrogen thiab oxygen thiab khaws cia cov hydrogen. Hauv cov txheej txheem kev xav no, lub roj teeb faib cov dej los tsim cov protons (hydrogen ions), thiab tom qab ntawd sib txuas cov hluav taws xob thiab cov hlau sib txuas ntawm cov hluav taws xob ntawm lub roj teeb uas siv roj teeb lithium.

Roj teeb lub zog cia tsim qauv

Thaum kawg, lub zog tau muab khaws cia rau hauv daim ntawv ntawm cov hlau hlau hydrides. Hauv cov txheej txheem thim rov qab, nws tuaj yeem tsim hluav taws xob (thiab dej) thiab ua ke cov protons nrog oxygen hauv huab cua (los ua dej).

“Cov roj rov qab siv tau cov roj teeb lithium” ua ke nrog cov khoom ruaj khov khaws cia hluav taws xob (X sawv rau cov hlau tsis muaj zog khi rau hydrogen)

Xibfwb Andrew tau hais tias, “Vim tias tsuas yog cov dej ntws mus rau hauv kev them nyiaj -tsuas yog huab cua ntws hauv hom kev tso tawm – peb hu lub kaw lus tshiab hu ua roj teeb proton. Piv nrog lithium-ion, cov roj teeb proton muaj kev lag luam ntau dua-Vim tias lithium xav tau kev khawb los ntawm cov peev txheej xws li cov zaub mov tsis txaus, dej ntsev lossis av nplaum. “

Flow roj teeb lub zog cia

Cov kws tshawb fawb tau hais tias, hauv paus ntsiab lus, kev siv hluav taws xob zoo ntawm cov roj teeb proton tuaj yeem piv rau cov roj teeb lithium-ion, tab sis lub zog ntom ntom yog ntau dua. Professor Andrew tau hais tias, “Thawj qhov kev sim ua tau zoo siab heev, tab sis tseem muaj ntau qhov kev tshawb fawb thiab kev txhim kho kom ua tiav ua ntej yuav muab tso rau hauv kev lag luam.”

Pab neeg no tau tsim thawj qhov pov thawj-ntawm-lub tswv yim tsab ntawv nrog qhov loj me ntawm tsuas yog 65x65x9 mm (2.5 × 2.5 × 0.3 inches) thiab luam tawm nws hauv “International Hydrogen Energy” magazine.
