Ucwaningo olusha oluvela e-University College London kanye ne-University of Oxford lubonisa ukuthi nakuba amabhethri e-lithium-ion akugwayi we-elekthronikhi alahlwayo alahlwa ngemva kokusetshenziswa okukodwa, angagcina umthamo omkhulu ngemva kwamakhulu emijikelezo.Ucwaningo lwesekwa yiFaraday Institute futhi lwashicilelwa kumagazini i-Joule.
Ukuduma kweama-e-cigarette alahlwayoinyuke kakhulu e-UK kusukela ngo-2021, ngocwaningo oluthola ukuthi ukuthandwa kukagwayi olahlwayo kukhuphuke ngokuphindwe ka-18 phakathi kukaJanuwari 2021 no-Ephreli 2022, okuholela ekutheni zonke izigidi zemishini yokufutha ilahlwe isonto ngalinye.
Ithimba locwaningo belinombono wokuthi amabhethri asetshenziswe ku-e-cigarettes olahlwayo angaphinda ashajwe, kodwa azikho izifundo zangaphambilini eziye zahlola impilo yebhethri yamabhethri e-lithium-ion kule mikhiqizo.
“Ama-e-cigarette alahlwayoziye zaqhuma ekudumeni eminyakeni yamuva.Naphezu kokuthengiswa njengemikhiqizo elahlekayo, ucwaningo lwethu lubonisa ukuthi amabhethri e-lithium-ion agcinwe ngaphakathi kwawo ayakwazi ukushajwa futhi akhishwe izikhathi ezingaphezu kuka-450.Lolu cwaningo lugqamisa ukuthi i-Sex Vaping iwukumosha okukhulu kwezinsiza ezilinganiselwe, ”kusho uHamish Reid, umbhali oholayo wocwaningo eSikoleni Sobunjiniyela Bamakhemikhali, e-University College London.
Ukuze bahlole umbono wabo, abacwaningi base-University College London nase-University of Oxford baqoqa amabhethri ezintweni ezilahlwayoi-e-cigarettesngaphansi kwezimo ezilawulwayo wabe esewahlola kusetshenziswa amathuluzi afanayo nezindlela ezisetshenziswa ukutadisha amabhethri ezimotweni zikagesi nezinye izinto..
Bahlola ibhethri ngaphansi kwesibonakhulu futhi basebenzisa i-X-ray tomography ukuze bahlele isakhiwo salo sangaphakathi futhi baqonde izinto eziyingxenye yalo.Ngokushaja ngokuphindaphindiwe nokukhipha amangqamuzana, banquma ukuthi amangqamuzana azigcina kanjani izakhiwo zawo ze-electrochemical ngokuhamba kwesikhathi, bathola ukuthi kwezinye izimo bangashajwa kabusha izikhathi ezingamakhulu.
USolwazi uPaul Shearing, umbhali omkhulu wephepha le-UCL's School of Chemical Engineering kanye ne-University of Oxford, uthe: “Okwasimangaza ukuthi imiphumela yabonisa ukuthi zinde kangakanani izikhathi zomjikelezo walawa mabhethri.Uma usebenzisa amanani aphansi wokushaja nokukhipha, ungabona Ngakho, ngemva kwemijikelezo engaphezu kuka-700, izinga lokugcinwa komthamo lisengaphezu kwama-90%.Eqinisweni, leli ibhethri elihle kakhulu.Zilahlwa nje bese ziphonswa nje eceleni komgwaqo.”
“Okungenani, umphakathi udinga ukuqonda izinhlobo zamabhethri asetshenziswa kule mishini kanye nesidingo sokuwalahla ngendlela efanele.Abakhiqizi kufanele bahlinzeke nge-ecosystem yei-e-cigarette ukusetshenziswa kabusha kwebhethri nokugaywa kabusha, futhi kufanele kwenze amadivayisi ashajwayo abe yikhona okuzenzakalelayo.”
USolwazi Shearing nethimba lakhe baphinde baphenye izindlela ezintsha, ezikhetheke kakhulu zokugaywa kabusha kwebhethri ezingase zigaywe kabusha izingxenye ngazinye ngaphandle kokungcola okuphambene, kanye namakhemistri ebhethri asimeme, okuhlanganisa amabhethri e-post-lithium-ion, amabhethri e-Lithium-sulphur namabhethri e-sodium-ion. .Ukuze kubhekwane nezinselele kulo lonke uchungechunge lokuhlinzekwa kwebhethri, ososayensi kufanele bacabangele umjikelezo wempilo yebhethri uma becubungula noma yiluphi uhlelo lokusebenza lwamabhethri.
