Iibhetri zeLithium-ion zibuchwephesha obuphantse bubekho kuyo yonke indawo ene-drawback enzima: ngamanye amaxesha zibamba umlilo.
Ividiyo yabasebenzi kunye nabakhweli kwinqwelomoya yeJetBlue begalela amanzi koobhaka babo iba ngumzekelo wamva nje wenkxalabo ebanzi malunga neebhetri, enokufumaneka ngoku phantse kuzo zonke izixhobo ezifuna amandla aphathwayo.Kwiminyaka elishumi edlulileyo, kukho ukwanda kwezihloko malunga nomlilo webhetri ye-lithium-ion obangelwa iibhayisikili zombane, iimoto zombane kunye neelaptops kwiinqwelomoya zabahambi.
Ukukhula kwenkxalabo yoluntu kuye kwaphefumlela abaphandi emhlabeni wonke ukuba basebenze ukuphucula ukhuseleko kunye nokuphila ixesha elide kweebhetri ze-lithium-ion.
Ukuveliswa kwebhetri sele kugqabhukile kwiminyaka yakutshanje, kunye nabaphandi benza iibhetri zombuso oqinileyo ngokutshintshela i-electrolyte yolwelo olunokutsha kwiibhetri eziqhelekileyo ze-lithium-ion kunye nezinto ezizinzileyo ze-electrolyte eziqinileyo ezifana neegels ezingenakutsha, iiglasi ze-inorganic kunye neepolima eziqinileyo.
Uphando olupapashwe kwiveki ephelileyo kwiphephancwadi leNdalo licebisa indlela entsha yokukhusela ukuthintela ukubunjwa kwe-lithium "dendrites," eyenzeka xa iibhetri ze-lithium-ion zigqithisa ngenxa yokugqithisa okanye ukonakalisa isakhiwo se-dendritic.I-Dendrites inokwenza iibhetri ezimfutshane kwaye ibangele imililo eqhumayo.
"Isifundo ngasinye sisinika ithemba elikhulu lokuba sinokucombulula iingxaki zokhuseleko kunye noluhlu lwezithuthi zombane," kusho uChongsheng Wang, uprofesa wezobunjineli beekhemikhali kunye ne-biomolecular kwiYunivesithi yaseMaryland kunye nombhali okhokelayo wokufunda.
Uphuhliso lukaWang linyathelo elibalulekileyo ekuphuculeni ukhuseleko lweebhetri ze-lithium-ion, utshilo uYuzhang Li, uprofesa oncedisayo wobunjineli beekhemikhali kwi-UCLA owayengabandakanyekanga kwisifundo.
U-Lee usebenza kwi-innovation yakhe, edala ibhetri yesinyithi ye-lithium yesizukulwana esilandelayo esinokugcina amandla aphindwe ka-10 ngaphezu kwamacandelo e-electrode yegraphite kwiibhetri ze-lithium-ion zemveli.
Xa kuziwa kukhuseleko lwesithuthi sombane, u-Lee uthe iibhetri ze-lithium-ion azikho yingozi okanye ziqhelekileyo njengoko uluntu lucinga, kwaye ukuqonda i-lithium-ion yokhuseleko lwebhetri ye-protocol kubalulekile.
"Zombini izithuthi zombane kunye neenqwelo eziqhelekileyo zinomngcipheko wendalo," watsho.Kodwa ndicinga ukuba iimoto zombane zikhuselekile ngakumbi kuba awuhlali phezu kweelitha zolwelo olunokutsha.
U-Lee wongezelela ukuba kubalulekile ukuthatha amanyathelo okuthintela ngokuchasene nokugqithiswa okanye emva kwengozi yemoto yombane.
Abaphandi abafunda imililo yebhetri ye-lithium-ion kwiZiko loPhando loMlilo elingenzi nzuzo bafumanise ukuba imililo kwizithuthi zombane ithelekiseka ngamandla nemililo yezithuthi eziqhutywa ngepetroli, kodwa imililo kwizithuthi zombane ihlala ixesha elide, ifuna amanzi amaninzi ukucima kwaye ingaphezulu. kunokwenzeka ukuba uvuthe.kwakhona.iiyure eziliqela emva kokuba ilangatye linyamalale ngenxa yamandla ashiyekileyo ebhetri.
UVictoria Hutchison, umphathi ophezulu wenkqubo yophando lwesiseko, wathi izithuthi zombane zibeka ingozi ekhethekileyo kubacimi bomlilo, abaphenduli bokuqala kunye nabaqhubi ngenxa yeebhetri zabo ze-lithium-ion.Kodwa oko akuthethi ukuba abantu mababoyike, wongeze watsho.
“Sisazama ukuqonda ukuba yeyiphi imililo yemoto yombane nokuba singayilwa njani na,” utshilo uHutcheson.“Ligophe lokufunda.Kudala sineenjini zomlilo zangaphakathi ixesha elide, yinto engaziwayo, kodwa kufuneka sifunde ukujongana nezi ziganeko ngokufanelekileyo.”
Iinkxalabo malunga nokutshiswa kwezithuthi zombane nazo zinokunyusa amaxabiso e-inshurensi, utshilo uMartti Simojoki, ingcaphephe yokuthintela ilahleko kwi-International Union ye-Inshurensi yaseLwandle.Uthe ukufaka i-inshorensi yezithuthi zombane njengempahla okwangoku yenye yezona ndlela zincinci zinomtsalane kwishishini kwiinshorensi, ezinokunyusa iindleko ze-inshurensi kwabo bajonge ukuthutha izithuthi zombane ngenxa yomngcipheko wokutsha.
Kodwa uphando olwenziwa yi-International Union of Marine Insurance, iqela elingenzi nzuzo elimele iinkampani zeinshorensi, lafumanisa ukuba iimoto zombane azikho yingozi okanye ziyingozi kuneemoto eziqhelekileyo.Enyanisweni, akuzange kuqinisekiswe ukuba umlilo ophezulu wempahla ovela kunxweme lwaseDutch kweli hlobo ubangelwa yimoto yombane, nangona iintloko zichaza ngenye indlela, uSimojoki uthe.
“Ndicinga ukuba abantu bayathandabuza ukuthatha umngcipheko,” utshilo.“Ukuba umngcipheko uphezulu, ixabiso liya kuba phezulu.Ekupheleni kosuku, umthengi wokugqibela uyayihlawula. ”
