Muva nje, i-Yadi kanye ne-People's Daily bethule ividiyo encane yenhlalakahle yomphakathi ethi “Ngubani umShayina?”, okuwukuvela konjiniyela wezobuchwepheshe we-Yadi graphene. Eminyakeni engaphezu kwemithathu yokuhlolwa, lonke ithimba le-Yadi R&D lathuthukisa ngempumelelo ibhethri le-Yadi graphene futhi laqeda intuthuko embonini yezimoto zikagesi. Ibhethri le-Yadi graphene lavunyelwa yi-People's Daily kanye ne-Communist Youth League Central Committee ngokwethulwa kwevidiyo encane yenhlalakahle yomphakathi.
I-Yadi ibilokhu ithuthukisa amabhethri e-graphene kusukela ngoJulayi 2016. NgoMeyi 2019, ibhethri le-graphene lead-acid likaYadi laqala ukukhiqizwa ngobuningi futhi laqanjwa ngokusemthethweni ngokuthi: i-Yadi Graphene Battery. NgoJuni walowo nyaka, i-Yadi Graphene Battery yakhululwa ngokusemthethweni. Kulokhu, ibhethri le-Yadi graphene njengokwethulwa kokuqala kwebhethri le-graphene embonini yezimoto zikagesi, alinakwa ukuze kukhuthazwe ukusungulwa kwemboni.
Ibhethri le-graphene le-Yadi lisebenzisa i-graphene composite super conductive paste, engasekela imijikelezo yokushaja nokukhipha engaphezu kuka-1000, okungaphezu kokuphindwe kathathu kunebhethri elivamile. Ngesikhathi esifanayo, ibhethri lisekela umsebenzi wokushaja okusheshayo wamanje, futhi lisebenzisana neshaja yokushaja okusheshayo yobungcweti. Ngaphansi, lingafinyelela umphumela wokushaja kufika ku-80% ngehora eli-1 kanye nokuqina kwamakhilomitha angu-50. Ngaphezu kwalokho, ibhethri le-graphene le-yadiene liphinde libe nebhokisi lebhethri elithuthukisiwe elihlanganisiwe elenziwe ngezinto ze-ABS, elinokumelana nokushisa okuphezulu, ukusebenza okuzinzile, njll. Izinzuzo zokusebenza, ukuvikela ibhethri ku--20 ° C -55 ° C kungaqhubeka nokukhipha amandla.
Ukubonakala kwebhethri le-Yadi graphene kuxazulule ngempumelelo izindawo ezibuhlungu zokuphila okufushane, ukushaja kancane, kanye nokuzulazula okungekuhle kwamabhethri ajwayelekile e-lead-acid, okunganikeza abasebenzisi ulwazi olujabulisayo.
Ekuqaleni kwethimba le-R&D, ithimba le-Yadi R&D likhethe i-graphene njengenye yezinto eziningi ezintsha. I-Graphene yaziwa ngokuthi “into yomlingo yokushintsha ikhulu lama-21” futhi inezakhiwo eziningi ezifana namandla aphezulu kanye nokushisa okuphezulu. Kodwa-ke, amasu okulungiselela endabuko afana nokususa imishini kanye nezindlela ze-redox nawo agcine izindleko ze-graphene ziphezulu, okuthinte kakhulu ukuthuthukiswa kwamabhethri e-Yadi graphene. Ngakho-ke, ngemuva kokuhlolwa okungaphezu kuka-400, ithimba le-Yadi R&D lathuthukisa ngempumelelo ubuchwepheshe bokulungiselela i-graphene obunelungelo lobunikazi futhi lakhiqiza i-graphene ngempumelelo ngokusebenzisa ubuchwepheshe obuyisisekelo, okunciphisa ngempumelelo izindleko zocwaningo nentuthuko.
Ngemuva kwalokho, ukuze kulungiswe i-paste ye-graphene composite superconducting ezinzile, ithimba le-Yadi R&D laqhubeka nokuqala ucwaningo olusha ngokujulile. Ukuze kuqashwe ngokucophelela ukulungiswa kwe-slurry, onjiniyela be-Yadi bavame ukuhlala elabhorethri, futhi sekuyinsakavukela ukubona ukuzinza kwemiphumela yokuhlolwa kwe-graphene. Ekugcineni, ngokusekelwe ezicini zezinto ze-graphene, bakhe uhlelo lwezinto olunezinhlangothi eziningi ngokusebenzisa ubuchwepheshe obuthathu ukuze bakhe ungqimba lwesakhiwo esizinzile kanye nenethiwekhi yokuhambisa uhlaka. Futhi le nqubo ihlolwe izikhathi ezingaphezu kuka-300. Isinyathelo sokugcina ekuthuthukisweni kwamabhethri e-graphene siwela ekuhlanganisweni kwe-paste ye-graphene composite superconducting kanye namabhethri e-lead-acid. Kuyo yonke imboni yezimoto zikagesi, amabhethri e-lead-acid aseyindlela ebaluleke kakhulu yokugcina amandla. Ukuguqula amabhethri e-lead-acid kube enye yezindlela ezinhle kakhulu zokukhuthaza imboni. Ithimba le-R&D le-Yadi laqaphela ukuhlanganiswa okuphelele kwezinto ze-graphene kanye ne-lead-acid ngokusebenzisa ubuchwepheshe be-vacuum atomization. Ucwaningo kanye nokuthuthukiswa kwebhethri le-Yadi graphene kwaqedwa ngokuyisisekelo. Okwamanje, yonke inqubo yocwaningo nentuthuko isibhekane nokuhlolwa okungaphezu kuka-900. Kodwa-ke, ithimba le-R&D elisezingeni eliphezulu likholelwa ukuthi leli bhethri linamandla okusebenzisa.
Kumabhethri e-lead-acid, inani lemijikelezo lingenye yeziphambeko ezinkulu. Onjiniyela be-Yadi basebenze kanzima ukuthuthukisa impilo yomjikelezo wamabhethri e-yadiene graphene ezivivinyweni ezingaphezu kuka-1000, okungazange kuxazulule nje kuphela ibhodi elifushane lamabhethri e-lead-acid. Kuphinde kunciphise kakhulu imvamisa yokubuyekezwa kwabathengi futhi kunikeze ulwazi olungcono.
Ngemva kokuba wonke umsebenzi wokucwaninga nokuthuthukiswa usuqediwe, i-Yadi yamemezela ngokusemthethweni ukwethulwa kwebhethri le-graphene le-Yadi ngasekupheleni kukaJuni 2019, futhi maqondana nesevisi, yathembisa ukuthi uma ibhethri linezinkinga zekhwalithi zingakapheli iminyaka emi-2, ukuhlolwa kuzoqinisekisa ukuthi isikhulu ngeke sinikeze sizathu. Ukuvuselelwa, kuwukuxazulula izinkinga zomsebenzisi. I-Yadi ayisebenzisi nje kuphela ubuchwepheshe obusha ukuqinisekisa umkhawulo ophambili wekhwalithi yomkhiqizo, kodwa futhi iphikelela ekuhlinzekeni abathengi ngolwazi olujabulisayo ngokusebenzisa izinguquko ezindaweni ezibuhlungu embonini.
(Isihloko esingenhla siphinde sakhiqizwa, asimeleli umbono we-Ningbo Vet, uma sihilela izinkinga ze-copyright, sicela uxhumane nathi ukuze sicutshungulwe)
