Fungidzira munhu anofembera achiudza vabereki vako, pazuva rawakazvarwa, kuti uchararama kwenguva yakareba sei. Chiitiko chakafanana chinogoneka kune vanoongorora mabhatiri vari kushandisa mamodheru matsva ekuverenga kuti vaverenge nguva yehupenyu hwebhatiri zvichibva pane data rimwe chete rekuyedza.

Muchidzidzo chitsva, vaongorori veUS Department of Energy's (DOE) Argonne National Laboratory vakashandisa simba rekudzidza kwemuchina kuti vafanotaura hupenyu hwemhando dzakasiyana dzemakemikari emabhatiri. Nekushandisa data rekuyedza rakaunganidzwa kuArgonne kubva kumabhatiri mazana matatu anomiririra makemikari matanhatu akasiyana emabhatiri, masayendisiti anogona kuona nemazvo kuti mabhatiri akasiyana acharamba achitenderera kwenguva yakareba sei.

Mune algorithm yekudzidza kwemuchina, masayendisiti anodzidzisa purogiramu yekombuta kuti iite fungidziro padata rekutanga, uye vozotora zvayakadzidza kubva mukudzidziswa ikoko kuti iite sarudzo pane rimwe data.

"Pamhando dzakasiyana dzemashandisirwo emabhatiri, kubva kunharembozha kusvika kumotokari dzemagetsi kusvika pakuchengetera grid, hupenyu hwebhatiri hwakakosha kune mutengi wese," akadaro musayendisiti wemakombiyuta wekuArgonne Noah Paulson, munyori wechidzidzo ichi. "Kufanira kutenderedza bhatiri kane zviuru kusvika rakundikana kunogona kutora makore; nzira yedu inogadzira rudzi rwekicheni yekuyedza mabhatiri kwatinogona kukurumidza kuona kuti mabhatiri akasiyana achaita sei."

"Parizvino, nzira chete yekuongorora kuti simba rebhatiri rinopera sei ndeyekutenderera bhatiri," akawedzera Argonne nyanzvi yemagetsi Susan "Sue" Babinec, mumwe munyori wechidzidzo ichi. "Zvinodhura zvikuru uye zvinotora nguva yakareba."

Sekureva kwaPaulson, maitiro ekugadzira hupenyu hwebhatiri anogona kuoma. "Chokwadi ndechekuti mabhatiri haagari kwenguva refu, uye kuti anogara kwenguva yakareba sei zvinoenderana nemashandisiro atinoita iwo, pamwe nekugadzirwa kwawo uye makemikari awo," akadaro. "Kusvika pari zvino, hapana nzira yakanaka yekuziva kuti bhatiri richagara kwenguva yakareba sei. Vanhu vachada kuziva kuti vane nguva yakareba sei kusvika vazoshandisa mari pabhatiri idzva."

Chimwe chinhu chakasiyana chekudzidza ndechekuti chaive nebasa guru rekuyedza rakaitwa kuArgonne pazvinhu zvakasiyana-siyana zve cathode yemabhatiri, kunyanya Argonne's patented nickel-manganese-cobalt (NMC)-based cathode. "Taive nemabhatiri aimiririra makemikari akasiyana, ane nzira dzakasiyana dzekuti aidzikira nekukundikana," akadaro Paulson. "Kukosha kwechidzidzo ichi ndechekuti chakatipa zviratidzo zvinoratidza mashandiro anoita mabhatiri akasiyana."

Kudzidza kwakawanda munharaunda iyi kune mukana wekutungamira ramangwana remabhatiri e-lithium-ion, akadaro Paulson. "Chimwe chezvinhu zvatinokwanisa kuita kudzidzisa algorithm pane chemistry inozivikanwa uye kuita kuti iite fungidziro pane chemistry isingazivikanwe," akadaro. "Chaizvoizvo, algorithm inogona kutibatsira kutitungamira munzira yemakemikari matsva uye akavandudzwa anopa hupenyu hwakareba."

Nenzira iyi, Paulson anotenda kuti machine learning algorithm inogona kukurumidzisa kugadzirwa nekuyedzwa kwezvinhu zvebhatiri. "Ngatitii une chinhu chitsva, wochitenderedza kashoma. Unogona kushandisa maalgorithm edu kufanotaura hurefu hwacho, wobva waita sarudzo yekuti unoda kuramba uchichitenderedza here kana kuti kwete."

"Kana uri muongorori murabhoritari, unogona kuwana nekuyedza zvimwe zvinhu zvakawanda munguva pfupi nekuti une nzira inokurumidza yekuzviongorora," Babinec akawedzera.

Pepa rakavakirwa pakudzidza, "Unyanzvi hwekudzidza kwemuchina hwakagonesa kufanotaura nguva yehupenyu hwebhatiri pakutanga,” yakabuda mumagazini yepamhepo yaKukadzi 25 yeJournal of Power Sources.

Kuwedzera kuna Paulson naBabinec, vamwe vanyori vepepa iri vanosanganisira Joseph Kubal waArgonne, Logan Ward, Saurabh Saxena naWenquan Lu.

Chidzidzo ichi chakatsigirwa nemari yeArgonne Laboratory-Directed Research and Development (LDRD).
