Tangoganizani wamatsenga akuwuza makolo anu, tsiku lomwe mudabadwa, mudzakhala nthawi yayitali bwanji.Zomwezi ndizotheka kwa akatswiri amankhwala a batri omwe akugwiritsa ntchito mitundu yatsopano yowerengera kuti awerengere nthawi yomwe batri imakhala ndi moyo kutengera kuzungulira kumodzi kwa data yoyesera.

Pakafukufuku watsopano, ofufuza ku US Department of Energy's (DOE) Argonne National Laboratory atembenukira ku mphamvu yophunzirira makina kuti athe kulosera za moyo wamitundu yambiri yama batri osiyanasiyana.Pogwiritsa ntchito zoyeserera zomwe zasonkhanitsidwa ku Argonne kuchokera pamabatire 300 omwe akuyimira ma chemistries asanu ndi limodzi osiyanasiyana, asayansi amatha kudziwa molondola kuti mabatire osiyanasiyana apitilize kuzungulira nthawi yayitali bwanji.

Mu algorithm yophunzirira makina, asayansi amaphunzitsa pulogalamu yapakompyuta kuti ipange malingaliro pa seti yoyamba ya data, kenako ndikutenga zomwe yaphunzira kuchokera kumaphunzirowo kuti ipange zisankho pagulu lina la data.

"Pamtundu uliwonse wa batire, kuyambira mafoni a m'manja kupita ku magalimoto amagetsi mpaka kusungirako gridi, moyo wa batri ndi wofunikira kwambiri kwa wogula aliyense," atero wasayansi wamakompyuta wa Argonne Noah Paulson, wolemba kafukufukuyu.“Kuyendetsa batire kambirimbiri kufikira italephera kungatenge zaka;njira yathu imapanga khitchini yoyeserera momwe tingadziwire mwachangu momwe mabatire amagwirira ntchito. ”

"Pakadali pano, njira yokhayo yodziwira momwe mphamvu ya batire imazirala ndikuyendetsa batire," adawonjezera Argonne electrochemist Susan "Sue" Babinec, wolemba wina wa kafukufukuyu."Ndiokwera mtengo kwambiri ndipo zimatenga nthawi yayitali."

Malinga ndi Paulson, njira yokhazikitsira moyo wa batri imatha kukhala yovuta."Zowona zake ndizakuti mabatire sakhalitsa, ndipo kuti amakhala nthawi yayitali bwanji zimadalira momwe timawagwiritsira ntchito, komanso kapangidwe kawo ndi momwe amapangira," adatero."Mpaka pano, palibe njira yabwino yodziwira kuti batire ikhala nthawi yayitali bwanji.Anthu akufuna kudziwa kuti akhala ndi nthawi yayitali bwanji mpaka atawononga ndalama pa batire yatsopano. ”

Chimodzi mwapadera pa kafukufukuyu ndikuti idadalira ntchito yayikulu yoyesera yomwe idachitika ku Argonne pazinthu zosiyanasiyana za cathode ya batri, makamaka cathode ya Argonne's patented nickel-manganese-cobalt (NMC)."Tinali ndi mabatire omwe amayimira ma chemistry osiyanasiyana, omwe ali ndi njira zosiyanasiyana zomwe angachepetse ndikulephera," adatero Paulson."Ubwino wa kafukufukuyu ndikuti udatipatsa zizindikiro zomwe zimawonetsa momwe mabatire amagwirira ntchito."

Kuphunzira kwina m'derali kuli ndi mwayi wotsogolera tsogolo la mabatire a lithiamu-ion, Paulson adati."Chimodzi mwazinthu zomwe timatha kuchita ndikuphunzitsa algorithm pa chemistry yodziwika ndikupangitsa kulosera pa chemistry yosadziwika," adatero."M'malo mwake, ma algorithm atha kutilozera komwe kuli ma chemistry atsopano komanso otsogola omwe amapereka moyo wautali."

Mwanjira imeneyi, Paulson amakhulupirira kuti makina ophunzirira makina amatha kufulumizitsa chitukuko ndi kuyesa zida za batri.“Nenani kuti muli ndi zinthu zatsopano, ndipo mumazizungulira kangapo.Mutha kugwiritsa ntchito algorithm yathu kulosera zautali wa moyo wake, kenako ndikupanga zisankho ngati mukufuna kupitiliza kuizungulira moyesera kapena ayi. ”

"Ngati ndinu wofufuza mu labu, mutha kupeza ndikuyesa zida zina zambiri munthawi yochepa chifukwa muli ndi njira yofulumira yoziwunika," adawonjezera Babinec.

Pepala lochokera pa phunziroli, "Uinjiniya wamakina ophunzirira makina adathandizira kulosera koyambirira kwa moyo wa batri,” adawonekera pa Feb. 25 pa intaneti ya Journal of Power Sources.

Kuphatikiza pa Paulson ndi Babinec, olemba ena a pepalali akuphatikizapo Argonne's Joseph Kubal, Logan Ward, Saurabh Saxena ndi Wenquan Lu.

Kafukufukuyu adathandizidwa ndi thandizo la Argonne Laboratory-Directed Research and Development (LDRD).
