Ukuthuthukiswa kwamandla ahlanzekile navuselelekayo kulisu elikhulu lentuthuko yezenhlalo nezomnotho yezwe lethu.Kuwo wonke amazinga obuchwepheshe bamandla amasha, ukugcinwa kwamandla e-electrochemical kunendawo ebaluleke kakhulu, futhi kuyindaba eshisayo ocwaningweni lwamanje lwesayensi.Njengohlobo olusha lwezinto eziqhutshwayo zesakhiwo esinezinhlangothi ezimbili, ukusetshenziswa kwegraphene kunokubaluleka okubalulekile namandla amakhulu okuthuthuka kulo mkhakha.

I-graphene futhi ingenye yezinto ezintsha ezithinteka kakhulu.Isakhiwo sawo sakhiwe ngama-symmetrical, ama-sub-lattice afakwe isidleke.I-Doping enama-athomu ahlukahlukene iyindlela ebalulekile yokuphula ukwakheka kwe-symmetric futhi iguqule izici zayo ezibonakalayo.Ama-athomu e-nitrogen anosayizi osondelene nowama-athomu ekhabhoni futhi kulula uma kuqhathaniswa ukuthi afakwe kwi-lattice ye-graphene.Ngakho-ke, i-nitrogen doping idlala indima ebalulekile ocwaningweni lwezinto ze-graphene.Ukufaka esikhundleni nge-doping kungasetshenziswa ukuguqula izakhiwo ze-electronic ze-graphene phakathi nenqubo yokukhula.

I-nitrogen ene-grapheneingavula igebe lebhendi yamandla futhi ilungise uhlobo lwe-conductivity, iguqule isakhiwo se-elekthronikhi, futhi ikhulise ukuminyana kwenkampani yenethiwekhi yamahhala, ngaleyo ndlela ithuthukise ukuqhutshwa nokuzinza kwe-graphene.Ngaphezu kwalokho, ukwethulwa kwezakhiwo ze-athomu eziqukethe i-nitrogen kugridi yekhabhoni yegraphene kungakhuphula amasayithi asebenzayo adsorbed endaweni yegraphene, ngaleyo ndlela kuthuthukise ukusebenzisana phakathi kwezinhlayiya zensimbi negraphene.Ngakho-ke, ukusetshenziswa kwe-graphene ye-nitrogen-doped yamadivayisi okugcina amandla kunokusebenza okuphezulu kakhulu kwe-electrochemical, futhi kulindeleke ukuthi kube into esebenza kahle kakhulu ye-electrode.Ucwaningo olukhona luphinde lubonise ukuthi i-graphene ene-nitrogen-doped ingathuthukisa kakhulu izici zomthamo, amandla wokushaja okusheshayo kanye nokukhipha kanye nempilo yomjikelezo wezinto zokugcina amandla, futhi inamandla amakhulu okusebenza emkhakheni wokugcinwa kwamandla.

I-graphene ene-nitrogen-doped

I-graphene ene-nitrogen-doped ingenye yezindlela ezibalulekile zokubona ukusebenza kwe-graphene, futhi idlala indima ebalulekile ekwandiseni izinkambu zohlelo lokusebenza.I-graphene ye-N-doped ingathuthukisa kakhulu izici zomthamo, ukushaja okusheshayo namandla okukhipha kanye nempilo yomjikelezo wezinto zokugcina amandla, futhi inamandla amakhulu okusebenza ezinhlelweni zokugcina amandla zamakhemikhali njengama-supercapacitors, i-lithium ion, i-lithium sulphur namabhethri omoya e-lithium.

Uma futhi unentshisekelo kwenye i-graphene esebenzayo, sicela ungangabazi ukusithinta.Isevisi eyengeziwe yokwenza ngokwezifiso inikezwa yi-Hongwu Nano.
