I-Australia iphuhlisa inkqubo yokuhamba kwebhetri ye-proton ngamandla amakhulu kuneebhetri ze-lithium
Sele zininzi izithuthi zebhetri ye-hydrogen esebenzisa amandla e-lithium kwimarike, kodwa abaphandi abavela kwiRoyal Melbourne Institute of Technology e-Australia babeke umbono wokuba “yiproton flow battery”. Ukuba itekhnoloji inokwandiswa, inokwandisa ukugubungelwa kweenkqubo zamandla ezisekwe kwi-hydrogen kwaye iyenze ibe yindawo enokubambela iibhetri ze-lithium-ion. ukufumana kwakhona i-hydrogen, isixhobo sokuhamba kweproton sisebenza ngakumbi njengebhetri ngengqondo yemveli.

Hlanganisa uNjingalwazi uJohnAndrews kunye “nenkqubo yebhetri yokuhamba kwebhetri” ubungqina bokuqala bengcinga yomzekelo

Inkqubo yendabuko ihambisa amanzi kwaye yahlule i-hydrogen kunye neoksijini, emva koko iwagcine kwiziphelo zombini zebhetri ye-lithium. Xa umbane sele uza kuvela, i-hydrogen kunye neoksijini zithunyelwa kwi-electrolyzer ukuze zisabele kwimichiza.

Nangona kunjalo, ukusebenza kwebhetri yokuhamba kwebhetri kwahlukile-kuba idibanisa i-electrode yensimbi yokugcina i-hydrode kwi-membrane yokubuyisela iproton (PEM) ye-lithium.

Ubungakanani beli sixhobo seprototype yi-65x65x9 mm

NgokukaJohn Andrews, umphandi ophambili weprojekthi kunye noprofesa onxulumene neSebe leMechanical and Manufacturing Engineering kwiRoyal Melbourne Institute of Technology (RMIT) School of Aerospace Engineering, ibhetri enee-electrode zokugcina ezihlanganisiweyo. Siyiphelisile ngokupheleleyo iproton ukuya kwigesi. Yonke le nkqubo, yenze ukuba i-hydrogen iye ngqo kwindawo yokugcina izinto. ”

Inkqubo yokuguqula igcina amandla ombane kwi-hydrogen emva koko “ivelise kwakhona” umbane

Inkqubo yokutshaja ayibandakanyi inkqubo yokubola kwamanzi kwi-hydrogen kunye neoksijini kunye nokugcina i-hydrogen. Kule nkqubo yokuqonda, ibhetri yahlulahlulahlula amanzi ukuvelisa iiproton (i-hydrogen ions), emva koko idibanisa ii-elektroni kunye namasuntswana esinyithi kwi-electrode yebhetri ye-lithium enikwe amandla.

Uyilo lwenkqubo yokugcina amandla ebhetri

Ekugqibeleni, amandla agcinwa ngohlobo lwehydrides zentsimbi eqinileyo. Kwinkqubo ebuyela umva, inokuvelisa umbane (kunye namanzi) kwaye idibanise iiproton kunye neoksijini esemoyeni (ukuvelisa amanzi).

“Ibhetri ye-lithium ebhetyebhetye yombane” edityaniswe nee-electrode zokugcina eziqinileyo (X imele iiathom zentsimbi eziqinileyo ezibotshelelwe kwihydrogen)

UNjingalwazi Andrew uthe, “Kuba kuphela kukuhamba kwamanzi kwimo yokutshaja-kuphela ukuhamba komoya kwimo yokukhupha-le nkqubo intsha siyibiza ngokuba yiproton flow battery. Xa kuthelekiswa ne-lithium-ion, iibhetri ze-proton zonga kakhulu- kuba i-lithium ifuna ukombiwa kwizixhobo ezinjengezimbiwa ezinqabileyo, amanzi anetyuwa okanye udongwe. ”

Ukuhamba kwamandla okugcina ibhetri

Abaphandi bathi, ngokomgaqo, ukusebenza kwamandla kweebhetri zokuhamba kweeproton kunokuthelekiswa neebhetri ze-lithium-ion, kodwa uxinano lwamandla lukhulu kakhulu. Unjingalwazi Andrew uthe, “Iziphumo zokuqala zovavanyo zinomdla, kodwa kusekho uphando kunye nomsebenzi wophuhliso ekufuneka wenziwe ngaphambi kokuba usetyenziselwe urhwebo.”

Iqela lakhe umboniso wokuqala wobungqina bemeko enobungakanani be-65x65x9 mm kuphela (2.5 × 2.5 × 0.3 intshi) kwaye wayipapasha kwiphephancwadi i- “International Hydrogen Energy”.
