Baytariyada lithium-ion waa tignoolajiyada ku dhawaad ​​meel walba laga heli karo oo leh cilad halis ah: mararka qaarkood dab ayay qabtaan.
Fiidiyowga shaqaalaha iyo rakaabka diyaaradda JetBlue oo si waali ah ugu shubaya biyaha boorsooyinkooda ayaa noqonaya tusaalihii ugu dambeeyay ee welwelka ballaaran ee ku saabsan baytariyada, kaas oo hadda laga heli karo ku dhawaad ​​qalab kasta oo u baahan awood la qaadi karo.Tobankii sano ee la soo dhaafay, waxaa kor u kacay wararka ciwaannada ah ee ku saabsan dabka baytariyada lithium-ion ee ay sababaan baaskiilada korontada, baabuurta korontada iyo laptop-yada ee duullimaadyada rakaabka.
Welwelka dadweynaha oo sii kordhaya ayaa dhiirigeliyay cilmi-baarayaasha adduunka oo dhan inay ka shaqeeyaan sidii ay u hagaajin lahaayeen badbaadada iyo cimriga baytariyada lithium-ion.
Hal-abuurnimada baytariga ayaa qarxinaysay sannadihii u dambeeyay, iyada oo cilmi-baarayaashu ay abuureen baytari adag oo dawladeed iyaga oo beddelaya electrolytes-ka dareeraha ah ee guban kara ee baytariyada lithium-ion ee caadiga ah oo leh walxo elektrolyte ah oo xasilloon oo xasilloon sida jeel aan guban karin, muraayadaha aan dabiiciga ahayn iyo polymers adag.
Cilmi-baaris lagu daabacay usbuucii hore joornaalka dabeecadda ayaa soo jeedinaysa hab cusub oo badbaado ah oo looga hortagayo samaynta lithium "dendrites", kaas oo sameysma marka baytariyada lithium-ion ay kuleylaan sababtoo ah xad-dhaaf ama waxyeello dhismaha dendritic.Dendrites waxay gaabin karaan baytariyada waxayna sababi karaan dab qarxa.
"Daraasad kastaa waxay ina siinaysaa kalsooni weyn oo ah inaan xallin karno badbaadada iyo dhibaatooyinka kala duwan ee baabuurta korontada," ayuu yiri Chongsheng Wang, oo ah borofisar ku takhasusay kiimikada iyo injineernimada biomolecular ee Jaamacadda Maryland iyo qoraaga hormuudka ah ee daraasadda.
Horumarinta Wang waa tallaabo muhiim ah oo lagu hagaajinayo badbaadada baytariyada lithium-ion, ayuu yiri Yuzhang Li, oo ah kaaliyaha borofisar ee injineerinka kiimikada ee UCLA oo aan ku lug lahayn daraasadda.
Lee waxa uu ka shaqaynayaa hal-abuurnimadiisa, isaga oo abuuraya baytari birta lithium-ka soo socda oo kaydin kara 10 jeer tamar ka badan qaybaha korantada graphite ee baytariyada dhaqameed ee lithium-ion.
Marka ay timaado badbaadada baabuurta korantada, Lee wuxuu sheegay in baytariyada lithium-ion aanay khatar u ahayn ama aanay u badnayn sida ay dadweynuhu u malaynayaan, iyo fahamka borotokoolka badbaadada baytariyada lithium-ion waa muhiim.
"Baabuurta korantada iyo baabuurta caadiga ah labaduba waxay leeyihiin khataro dabiici ah," ayuu yidhi."Laakin waxaan filayaa in baabuurta korantada ay ka badbaado badan yihiin sababtoo ah kuma fadhidid gallon oo dareere ah oo guban kara."
Lee waxa uu intaa ku daray in ay muhiim tahay in la qaado tallaabooyin ka hortag ah oo lagaga hortagayo in lagu dalaco ama ka dib shil baabuur oo koronto ah.
Cilmi-baarayaal daraasad ku sameynayay dabka batariyada lithium-ion ee Hay’adda Cilmi-baarista Dab-damiska ee aan faa’iido doonka ahayn waxay ogaadeen in dabka ka kaca baabuurta korontadu uu la barbardhigi karo xoogga dabka baabuurta dhaqameed ee ku shaqeeya shidaalka, laakiin dabka gawaarida korontada ayaa u muuqda inuu sii dheeraado, wuxuu u baahan yahay biyo badan si uu u damiyo oo aad u badan. ay u badan tahay in uu shido.mar kale.dhowr saacadood ka dib markii ololku baaba'o sababtoo ah tamarta haraaga ah ee batteriga.
Victoria Hutchison, oo ah maareeyaha sare ee barnaamijka cilmi baarista ee aasaaska, ayaa sheegtay in baabuurta korantada ay khatar gaar ah u yihiin dab-demiska, jawaabeyaasha koowaad iyo darawallada sababtoo ah baytarigooda lithium-ion.Laakiin taasi macnaheedu maaha inay dadku ka cabsadaan, ayay raacisay.
"Waxaan wali isku dayeynaa inaan fahanno waxa ay yihiin dabka gawaarida korontada ku shaqeeya iyo sida ugu wanaagsan ee loola dagaallamo," Hutcheson ayaa yidhi.“Waa qalooca waxbarashada.Waxa aanu haysanay baabuurta matoorada gubashada gudaha muddo dheer hadda, waa wax aan la garanayn, laakiin waa in aan baranaa sida saxda ah ee loo wajaho dhacdooyinkan. "
Walaaca ku saabsan dabka gawaarida korantada ayaa sidoo kale kor u qaadi kara qiimaha caymiska, ayuu yiri Martti Simojoki, khabiir ka hortagga khasaaraha ee Ururka Caalamiga ah ee Caymiska Badda.Waxa uu sheegay in baabuurta korantada lagu caymiyo shixnad ahaan ay hadda tahay mid ka mid ah khadadka ugu soo jiidashada yar ee ganacsiyada caymisyada, taas oo kordhin karta kharashka caymiska kuwa doonaya in ay qaadaan baabuurta korontada sababtoo ah khatarta dabka ee loo arko.
Laakiin daraasad ay samaysay Ururka Caalamiga ah ee Caymiska Badda, oo ah koox aan faa'iido doon ahayn oo matalaysa shirkadaha caymiska, ayaa lagu ogaaday in baabuurta korontadu aanay ka khatar badanayn ama ka khatar badanayn baabuurta caadiga ah.Dhab ahaantii, lama xaqiijin in dab-damis heersare ah oo ka kacay xeebta Nederland xagaagan uu sababay baabuur koronto ah, inkastoo cinwaannada ay soo jeedinayaan si kale, ayuu yiri Simojoki.
"Waxaan u maleynayaa in dadku ay ka caga jiidayaan in ay halis galiyaan," ayuu yidhi."Haddii khatartu sarreyso, qiimuhu wuu sarreeyaa.Dhammaadka maalinta, macaamilka dhamaadka ah ayaa bixinaya kharashka."
