Khawube nomfanekiso wengqondo exelela abazali bakho, ngomhla wokuzalwa kwakho, ukuba uyakuphila ixesha elingakanani.Amava afanayo ayenzeka kwiikhemisti zebhetri ezisebenzisa imifuziselo emitsha yokubala ukubala ubomi bebhetri ngokusekwe kumjikelo omncinci wedatha yovavanyo.

Kuphononongo olutsha, abaphandi kwiSebe le-US ye-Energy's (DOE) i-Argonne National Laboratory baye baphendukela kumandla okufunda ngomatshini ukuqikelela ixesha lokuphila koluhlu olubanzi lweekhemistri zebhetri ezahlukeneyo.Ngokusebenzisa idatha yovavanyo eqokelelwe eArgonne ukusuka kwiseti yeebhetri ezingama-300 ezimele iikhemistri zebhetri ezintandathu ezahlukeneyo, izazinzulu zinokumisela ngokuchanekileyo ukuba iibhetri ezahlukeneyo ziya kuqhubeka ixesha elingakanani ukujikeleza.

Kwi-algorithm yokufunda ngomatshini, izazinzulu ziqeqesha inkqubo yekhompyuter ukwenza intelekelelo kwiseti yokuqala yedatha, kwaye emva koko ithathe oko ikufundileyo kolo qeqesho ukwenza izigqibo kwenye iseti yedatha.

"Kulo lonke uhlobo olwahlukileyo lwesicelo sebhetri, ukusuka kwiiselfowuni ukuya kwizithuthi zombane ukuya kwigridi yokugcina igridi, ixesha lokuphila kwebhetri libaluleke kakhulu kuye wonke umthengi," utshilo u-Argonne isazi sezibalo uNowa Paulson, umbhali wophononongo.“Ukuqhuba ibhetri kangangezihlandlo ezingamawaka de lisilele kunokuthabatha iminyaka;indlela yethu idala uhlobo lwekhitshi lovavanyo lwekhompyutha apho sinokufumanisa ngokukhawuleza ukuba zisebenza njani iibhetri ezahlukeneyo.

“Okwangoku, ekuphela kwendlela yokuvavanya ukuba amandla ebhetri aphela njani kukujikeleza ibhetri,” wongeze watsho u-Argonne electrochemist uSusan “Sue” Babinec, omnye umbhali wolu phononongo."Ibiza kakhulu kwaye ithatha ixesha elide."

NgokukaPaulson, inkqubo yokuseka ubomi bebhetri inokuba luqilima."Inyani yeyokuba iibhetri azihlali ngonaphakade, kwaye zihlala ixesha elingakanani kuxhomekeke kwindlela esizisebenzisa ngayo, kunye noyilo lwazo kunye nekhemistri," watsho.Ukuza kuthi ga ngoku, ayikakabikho ndlela intle yokwazi ukuba ibhetri iya kuhlala ixesha elingakanani.Abantu baya kufuna ukwazi ukuba banexesha elingakanani de bachithe imali kwibhetri entsha. ”

Enye inkalo eyodwa yophononongo kukuba ixhomekeke kumsebenzi wovavanyo obanzi owenziwe e-Argonne kwiintlobo ngeentlobo zemathiriyeli yecathode yebhetri, ngakumbi i-Argonne's patented nickel-manganese-cobalt (NMC)-based cathode.“Besineebhetri ezimele iikhemistri ezahlukeneyo, ezineendlela ezahlukeneyo zokuthoba isidima kwaye basilele,” utshilo uPaulson."Ixabiso lolu phononongo kukuba lusinike imiqondiso ebonisa indlela iibhetri ezisebenza ngayo."

Uphononongo olongezelelweyo kule ndawo lunamandla okukhokela ikamva leebhetri ze-lithium-ion, utshilo uPaulson."Enye yezinto esikwaziyo ukuzenza kukuqeqesha i-algorithm kwi-chemistry eyaziwayo kwaye yenze uqikelelo kwi-chemistry engaziwayo," watsho."Ngokusisiseko, i-algorithm inokusinceda ukuba isikhombe kwicala leekhemistri ezintsha neziphuculweyo ezibonelela ubomi obude."

Ngale ndlela, uPaulson ukholelwa ukuba i-algorithm yokufunda umatshini inokukhawulezisa uphuhliso kunye novavanyo lwezixhobo zebhetri.“Yithi unemathiriyeli entsha, kwaye uyijikelezisa amaxesha ambalwa.Unokusebenzisa i-algorithm yethu ukuqikelela ubomi bayo obude, kwaye emva koko wenze izigqibo zokuba uyafuna na ukuqhubeka nokuyijikeleza ngokulinga okanye hayi. ”

“Ukuba ungumphandi kwilebhu, ungafumanisa kwaye uvavanye izixhobo ezininzi ngexesha elifutshane kuba unendlela ekhawulezayo yokuzivavanya,” wongeze watsho uBabinec.

Iphepha elisekelwe kwisifundo, "Ubunjineli bobuNjineli bokufunda koomatshini buvuleleke kuqikelelo lwangethuba lobomi bebhetri,” yavela kwi-25 kaFebruwari kwi-intanethi ye-Journal yemithombo yamandla.

Ukongeza kuPaulson kunye noBabinec, abanye ababhali bephepha baquka u-Argonne's Joseph Kubal, iLogan Ward, uSaurabh Saxena kunye noWenquan Lu.

Uphononongo luxhaswe ngemali yesibonelelo seArgonne Laboratory-Directed Research and Development (LDRD).
