Nahana ka senohe se bolella batsoali ba hao, ka letsatsi leo u tsoetsoeng ka lona, hore na u tla phela nako e kae.Phihlelo e ts'oanang e ka etsahala bakeng sa litsebi tsa lik'hemik'hale tsa betri tse sebelisang mefuta e mecha ea khomphutha ho bala nako ea bophelo ba betri ho ipapisitsoe le sekhechana se le seng sa data ea liteko.
Phuputsong e ncha, bafuputsi Lefapheng la Matla la US (DOE) Argonne National Laboratory ba fetohetse matla a ho ithuta ka mochine ho bolela esale pele nako ea bophelo ea lik'hemik'hale tse fapaneng tsa betri tse fapaneng.Ka ho sebelisa lintlha tsa liteko tse bokelletsoeng Argonne ho tsoa ho sete ea libeteri tse 300 tse emelang lik'hemik'hale tse tšeletseng tse fapaneng tsa betri, bo-ramahlale ba ka tseba ka nepo hore na libeteri tse fapaneng li tla tsoelapele ho potoloha nako e kae.

Ho algorithm ea ho ithuta ka mochini, bo-ramahlale ba koetlisa lenaneo la khomphutha ho etsa likhakanyo ho sete ea pele ea data, ebe ba nka seo ba ithutileng sona thupelong eo ho etsa liqeto ka sete e 'ngoe ea data.
"Bakeng sa mofuta o mong le o mong o fapaneng oa ts'ebeliso ea betri, ho tloha ho liselefouno ho isa likoloing tsa motlakase ho ea polokelong ea marang-rang, nako ea bophelo ba betri ke ea bohlokoa ho moreki e mong le e mong," ho boletse rasaense oa Argonne oa computational Noah Paulson, sengoli sa thuto.“Ho palama betri ka makgetlo a dikete ho fihlela e hloleha ho ka nka dilemo;mokhoa oa rona o theha mofuta oa kichine ea tlhahlobo ea komporo moo re ka tsebang kapele hore na libeteri tse fapaneng li tla sebetsa joang. ”
"Hona joale, tsela e le 'ngoe feela ea ho lekola hore na matla a betri a fela joang ke ho tsamaisa betri," ho phaella setsebi sa electrochemist ea Argonne Susan "Sue" Babinec, sengoli se seng sa thuto."E turu haholo 'me e nka nako e telele."
Ho ea ka Paulson, mokhoa oa ho theha bophelo ba betri e ka ba ntho e qhekellang.’Nete ke hore libeteri ha li tšoarelle ka ho sa feleng, ’me hore na li tšoarella nako e kae ho itšetlehile ka tsela eo re li sebelisang ka eona, hammoho le moralo oa tsona le k’hemistri ea tsona,” o ile a re.“Ho fihlela joale, ha ho so be le mokhoa o motle oa ho tseba hore na betri e tla tšoarella nako e kae.Batho ba tla batla ho tseba hore na ba na le nako e kae ho fihlela ba tlameha ho sebelisa chelete ka betri e ncha. ”
Karolo e 'ngoe e ikhethang ea phuputso ke hore e itšetlehile ka mosebetsi o pharaletseng oa liteko o entsoeng Argonne ka mefuta e fapaneng ea lisebelisoa tsa cathode ea betri, haholo-holo cathode ea Argonne e nang le patente ea nickel-manganese-cobalt (NMC)."Re ne re e-na le libeteri tse emelang lik'hemik'hale tse fapaneng, tse nang le litsela tse fapaneng tseo li neng li ka li theola le ho hlōleha," ho boletse Paulson."Boleng ba phuputso ena ke hore e re file matšoao a bontšang hore na libeteri tse fapaneng li sebetsa joang."
Boithuto bo eketsehileng sebakeng sena bo na le monyetla oa ho tataisa bokamoso ba libeteri tsa lithium-ion, Paulson o itse."E 'ngoe ea lintho tseo re khonang ho li etsa ke ho koetlisa algorithm ho k'hemistri e tsebahalang le ho etsa hore e bolele esale pele ka k'hemistri e sa tsejoeng," o boletse joalo."Ha e le hantle, algorithm e ka re thusa ho re supisa tsela ea lik'hemik'hale tse ncha le tse ntlafalitsoeng tse fanang ka nako e telele ea bophelo."
Ka tsela ena, Paulson o lumela hore algorithm ea ho ithuta mochini e ka potlakisa nts'etsopele le tlhahlobo ea lisebelisoa tsa betri.“E re u na le boitsebiso bo bocha, ’me u bo potoloha ka makhetlo a ’maloa.U ka sebelisa algorithm ea rona ho bolela esale pele hore na e tla phela nako e telele hakae, ebe u etsa liqeto tsa hore na u batla ho tsoela pele ho e potoloha ka liteko kapa che. ”
"Haeba u mofuputsi ka laboratoring, u ka fumana le ho leka lisebelisoa tse ling tse ngata ka nako e khuts'oane hobane u na le mokhoa o potlakileng oa ho li hlahloba," Babinec a eketsa.
Pampiri e thehiloeng thutong, "Boenjiniere ba ho ithuta ka mochini bo nolofalitse ho bolela esale pele nako ea bophelo ba betri,” e hlahile khatisong ea Inthanete ea Feb. 25 ea Journal of Power Sources.
Ho phaella ho Paulson le Babinec, bangoli ba bang ba pampiri ba kenyelletsa Argonne's Joseph Kubal, Logan Ward, Saurabh Saxena le Wenquan Lu.
