Uphando olutsha oluvela kwiYunivesithi yaseLondon kunye neYunivesithi yaseOxford lubonisa ukuba nangona iibhetri ze-lithium-ion kwi-e-cigarettes ezilahlayo zilahlwa emva kokusetyenziswa okukodwa, ziyakwazi ukugcina umthamo ophezulu emva kwamakhulu emijikelezo.Uphando lwaxhaswa yiFaraday Institute kwaye lwapapashwa kwiphephancwadi iJoule.
Ukuthandwa kweI-e-cigarettes elahlayoiye yanda e-UK ukusukela ngo-2021, kuphando olufumanise ukuba ukuthandwa kwee-e-cigarettes ezilahlwayo kunyuke ka-18 phakathi kukaJanuwari 2021 kunye no-Epreli 2022, okukhokelela kuzo zonke izigidi zezixhobo zokufutha zilahlwa veki nganye.
Iqela lophando lalinombono wokuba iibhetri ezisetyenziswe kwi-e-cigarettes ezilahlayo zihlaziywa, kodwa akukho zifundo zangaphambili eziye zavavanya ubomi bebhetri yeebhetri ze-lithium-ion kule mveliso.
“I-e-cigarettes elahlayoziye zanda kakhulu kwiminyaka yakutshanje.Nangona kuthengiswa njengeemveliso ezilahlayo, uphando lwethu lubonisa ukuba iibhetri ze-lithium-ion ezigcinwe ngaphakathi kwazo ziyakwazi ukuhlawuliswa kwaye zikhutshwe ngaphezu kwamaxesha e-450.Olu phononongo luqaqambisa indlela i-Sex vaping enye eyinkcitho enkulu yezixhobo ezinqongopheleyo, utshilo uHamish Reid, umbhali okhokelayo wophononongo ovela kwiSikolo soBunjineli beMichiza, kwiKholeji yeYunivesithi yaseLondon.
Ukuvavanya i-hunch yabo, abaphandi abavela kwiYunivesithi yaseLondon yaseLondon kunye neYunivesithi yaseOxford baqokelela iibhetri kwizinto ezilahlwayoi-e-cigarettesphantsi kweemeko ezilawulwayo kwaye emva koko bavavanya kusetyenziswa izixhobo ezifanayo kunye nobuchule obusetyenziselwa ukufunda iibhetri kwiimoto zombane kunye nezinye izixhobo..
Baye bavavanya ibhetri phantsi kwe-microscope kwaye basebenzisa i-X-ray tomography ukwenza imephu yesakhiwo sayo sangaphakathi kunye nokuqonda izixhobo zayo.Ngokutshaja ngokuphindaphindiweyo kunye nokukhupha iiseli, bamisela indlela iiseli ezizigcina ngayo iipropathi zazo ze-electrochemical ekuhambeni kwexesha, zifumanisa ukuba kwezinye iimeko zinokuphinda zitshajwe ngamakhulu amaxesha.
Unjingalwazi uPaul Shearing, umbhali ophambili weli phepha kwiSikolo se-UCL sobuNjineli beMichiza kunye neYunivesithi yaseOxford, wathi: “Okothusayo kukuba, iziphumo zibonise ukuba lide kangakanani ixesha lomjikelo wezi bhetri.Ukuba usebenzisa intlawulo ephantsi kunye namazinga okukhutshwa, ungabona Ngoko ke, emva kwemijikelo engaphezu kwama-700, izinga lokugcinwa kwamandla lisengaphezulu kwe-90%.Enyanisweni, eli libhetri elihle kakhulu.Zilahlwa nje zize ziphoswe ngokungalindelekanga ecaleni kwendlela.”
“Ubuncinci, uluntu kufuneka luqonde iindidi zeebhetri ezisetyenziswa kwezi zixhobo kunye nesidingo sokuzilahla ngokuchanekileyo.Abavelisi kufuneka babonelele nge-ecosystemi-e-cigarette ukusetyenziswa kwakhona kwebhetri kunye nokurisayikilisha, kwaye kufuneka zenze izixhobo eziphinda zitshajwe zibe yinto ehlala ihleli.”
Unjingalwazi uShearing kunye neqela lakhe baphinda baphande iindlela ezintsha, ezikhethiweyo zokuphinda zisetyenziswe ibhetri ezinokuphinda zisetyenziselwe izixhobo zomntu ngamnye ngaphandle kongcoliseko olunqamlezayo, kunye neekhemistri zebhetri ezizinzileyo, kubandakanya iibhetri ze-post-lithium-ion, iibhetri zeLithium-sulphur kunye neebhetri zesodium-ion. .Ukujongana nemiceli mngeni kulo lonke unikezelo lwebhetri, izazinzulu kufuneka zithathele ingqalelo umjikelo wobomi bebhetri xa ziqwalasela nasiphi na isicelo seebhetri.
