Isikhungo socwaningo saseBelgium i-Imec simemezele ukuthuthukiswa kobuchwepheshe obungabizi bokukhiqiza izinto ezinanoporous ezinezakhiwo ezivelele. Impahla eyingqayizivele, ngendlela yesakhiwo se-nanocellular, ine-porosity ephezulu kakhulu kanye nesilinganiso esingakaze sibe khona se-surface-to-volume. Cabanga ngethini elincane lesoda, u-75% wokuqukethwe yi-void enendawo ephelele elingana nenkundla yebhola. Ngesikhathi esifanayo, ukukhiqizwa kwezinto ezibonakalayo kulula futhi akubizi, futhi cishe noma iyiphi insimbi ingasetshenziswa njengesisekelo sayo. Ngakho-ke, ububanzi bokusetshenziswa kwezinto ezinjalo ze-nanoporous zingaba zikhulu kakhulu.
Kodwa-ke, inhloso eyinhloko yento entsha enesakhiwo se-nanoporous kanye nendawo enkulu yangaphakathi ibonakala iwukusabela kwamakhemikhali okudinga izindawo ezinkulu ukusheshisa ukusabela. Isibonelo, lawa kungaba amabhethri e-lithium-ion, lapho ukwanda kwendawo yokusabela yokuguqula i-lithium ibe yi-lithium ion kuholela ekwandeni kokuphuma kwamandla nokusebenza kahle. Ngaphezu kwalokho, imvelo ye-metallic ye-nanomaterial ivumela othintana nabo abaqoqa manje ukuthi baxhunywe kuyo ngqo. Impahla enezimbotshana izophinde ithuthukise ukusebenza kwamaseli kaphethiloli namasistimu okukhipha i-hydrogen emanzini. Esikhundleni se-catalytic membrane eyenziwe nge-nickel enegwebu cishe ugqinsi lwamamilimitha, isibonelo, into entsha inomzimba omncane izikhathi ezingu-300, kodwa inikeza umphumela ofanayo ne-nickel. Amandla aluhlaza namabhethri angase abe nethuba lokubona ukuthuthuka okubalulekile kubuchwepheshe nezisombululo.
Ukukhiqizwa kwezinto ezintsha kulula, njengoba kushiwo ngenhla. Okokuqala, isikhunta senziwe nge-aluminium foil nge-anodizing. Khona-ke inqubo ye-electroplating iqalwa ngokufakwa okunembile kwensimbi ye-aluminium (noma enye insimbi). Ngemuva kokugcwalisa i-voids ekubunjweni, lokhu kuchithwa, kukhulula isakhiwo seselula se-nanowires. I-strip ye-nanoporous material ibukeka njenge-foil. Iyagoba futhi ayiphuli, ngokungafani nezinto zesimanje ze-nanoporous ezenziwe ngendlela ehlukile. Silindele ukuqaliswa okungokoqobo. Sidinga amabhethri amaningi kakhulu afanayo.
