Abaphenyi babikezele inethiwekhi entsha yekhabhoni, efana ne-graphene, kepha ngokuhleleka okuyinkimbinkimbi, okungaholela kumabhethri ezimoto angcono kakhulu kagesi. I-Graphene kuyimpikiswano edumile kakhulu yekhabhoni. Kutholwe njengomthetho omusha we-Game Game we-Lithium-Ion Technology, kepha izindlela ezintsha zokukhiqiza zingagcina zikhiqiza amabhethri amaningi agxile anamandla.
I-graphene ingabonakala njengenethiwekhi yama-athomu e-carbon, lapho i-athomu ngayinye ye-carbon exhunywe khona ama-athomu amathathu asondelene nekhabhoni ukukhiqiza ama-hexagons amancane. Kodwa-ke, abaphenyi bacabanga ukuthi ngaphezu kwale nokhetho lezinyosi lezinyosi eziqondile, ezinye izinhlaka nazo zingenziwa.
Lokhu kungenxa yezinto ezintsha ezenziwe yiqembu elivela e-University of Marburg eJalimane nase-Aalto University eFinland. Babeka ama-athomu e-carbon abe izinkomba ezintsha. Inethiwekhi okuthiwa yi-biphenyl inethiwekhi yakhiwa ama-hexagons, izigcawu kanye nama-octagons, okuyigridi eyinkimbinkimbi kakhulu kune-graphene. Abaphenyi bathi lokho, kuhluke kakhulu, futhi ngandlela thile, izakhiwo ezifiselekayo ze-elekthronik.
Isibonelo, yize i-graphene yenzelwe ikhono layo njenge-semiconductor, inethiwekhi entsha yekhabhoni iziphatha njengensimbi. Eqinisweni, lapho kuphela ama-athomu angama-21 ububanzi, imivimbo yenethiwekhi ye-biphenyl ingasetshenziswa njengemicu evuthayo yamadivayisi kagesi. Bakukhombe ukuthi ngalesi sikali, iGronnel isenza njenge-semiconductor.
Umlobi ophambili uthe: "Lolu hlobo olusha lwenethiwekhi yekhabhoni lungasetshenziswa njengento enhle ye-anode yamabhethri e-lithium-ion.
I-anode yebhethri le-lithium-ion livame ukwakhiwa i-graphite elisakazeka kwi-foil yethusi. Inokuqhutshwa okuphezulu kagesi, okungagcini nje ngokufaka i-lithium ion phakathi kwezendlalelo zayo, kepha futhi futhi ngoba kungaqhubeka ukwenza lokho ngezinkulungwane zemijikelezo. Lokhu kwenza kube nebhethri elisebenza kahle kakhulu, kepha futhi ibhethri elingahlala isikhathi eside ngaphandle kokonakaliswa.
Kodwa-ke, ezinye izindlela ezisebenza kahle nezincane ezisuselwa kule Nkundla entsha yekhabhoni kungenza ukulondolozwa kwamandla kwebhethri kukhulu ngokwengeziwe. Lokhu kungenza izimoto zikagesi namanye amadivaysi asebenzisa amabhethri e-lithium-ion amancane futhi alula.
Kodwa-ke, njenge-graphenee, ukuthola ukuthi ungayenza kanjani le nguqulo entsha ngezinga elikhulu kuyinselelo elandelayo. Indlela yamanje yoMkhakha Yomhlangano Ithembele ebusweni obuhle kakhulu begolide lapho ama-molecule e-carbon-aqukethe khona ekuqaleni amaketanga we-hexagonal. Ukuphendula okulandelayo kuxhuma la maketanga ukuze kwakha amajamo wesikwele kanye ne-octagonal, okwenza umphumela wokugcina uhlukile kwe-grapheENE.
Abaphenyi bachaza ukuthi: "Umqondo omusha ukusebenzisa abenduli be-molecular elungisiwe ukukhiqiza i-biphenyl esikhundleni se-graphenel. Inhloso manje ukukhiqiza amashidi amakhulu wezinto ezibonakalayo ukuze izakhiwo zayo ziqondwe kangcono."
