Tangoganizirani zamatsenga akuuza makolo anu, tsiku lomwe munabadwa, nthawi yomwe mudzakhala ndi moyo. Chochitika chofananachi n'chotheka kwa akatswiri a zamankhwala a batri omwe akugwiritsa ntchito mitundu yatsopano ya makompyuta kuti awerengere nthawi ya moyo wa batri kutengera kuchuluka kwa deta yoyesera.

Mu kafukufuku watsopano, ofufuza ku US Department of Energy's (DOE) Argonne National Laboratory agwiritsa ntchito mphamvu ya kuphunzira kwa makina kuti alosere nthawi ya moyo wa mitundu yosiyanasiyana ya mankhwala a batri. Pogwiritsa ntchito deta yoyesera yomwe yasonkhanitsidwa ku Argonne kuchokera ku mabatire 300 omwe akuyimira mankhwala asanu ndi limodzi osiyanasiyana a mankhwala a batri, asayansi amatha kudziwa molondola nthawi yomwe mabatire osiyanasiyana adzapitirire kuzungulira.

Mu njira yophunzirira makina, asayansi amaphunzitsa pulogalamu ya pakompyuta kuti ipange malingaliro pa deta yoyambirira, kenako n’kutenga zomwe yaphunzira kuchokera ku maphunzirowo kuti ipange zisankho pa deta ina.

"Pa mtundu uliwonse wa mabatire, kuyambira mafoni am'manja mpaka magalimoto amagetsi mpaka malo osungira magetsi, nthawi yogwiritsira ntchito batri ndi yofunika kwambiri kwa aliyense," anatero wasayansi wa makompyuta ku Argonne Noah Paulson, wolemba kafukufukuyu. "Kukhala ndi batri nthawi zambiri mpaka italephera kungatenge zaka zambiri; njira yathu imapanga mtundu wa khitchini yoyesera makompyuta komwe tingathe kudziwa mwachangu momwe mabatire osiyanasiyana adzagwirira ntchito."

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

Malinga ndi Paulson, njira yokhazikitsira nthawi ya batri ikhoza kukhala yovuta. "Chowonadi ndi chakuti mabatire sakhalitsa, ndipo nthawi yawo imakhala yayitali bwanji kutengera momwe timawagwiritsira ntchito, komanso kapangidwe kawo ndi kapangidwe kawo," adatero. "Mpaka pano, palibe njira yabwino yodziwira nthawi yomwe batire lidzakhala. Anthu adzafuna kudziwa nthawi yomwe ali nayo mpaka atagwiritsa ntchito ndalama pa batire yatsopano."

Mbali imodzi yapadera ya kafukufukuyu ndi yakuti idadalira ntchito yayikulu yoyesera yomwe idachitika ku Argonne pazinthu zosiyanasiyana za cathode ya batri, makamaka cathode yochokera ku Argonne yokhala ndi nickel-manganese-cobalt (NMC). "Tinali ndi mabatire omwe amayimira mitundu yosiyanasiyana ya mankhwala, omwe ali ndi njira zosiyanasiyana zomwe angawonongeke ndikulephera," adatero Paulson. "Kufunika kwa kafukufukuyu ndikuti adatipatsa zizindikiro zomwe zimadziwika ndi momwe mabatire osiyanasiyana amagwirira ntchito."

Kafukufuku wowonjezereka m'derali ali ndi kuthekera kotsogolera tsogolo la mabatire a lithiamu-ion, adatero Paulson. "Chimodzi mwazinthu zomwe timatha kuchita ndikuphunzitsa algorithm pa chemistry yodziwika bwino ndikuilola kuti ilosere za chemistry yosadziwika," adatero. "Kwenikweni, algorithm ingatithandize kutitsogolera ku njira zatsopano komanso zabwino zomwe zimapereka moyo wautali."

Mwanjira imeneyi, Paulson akukhulupirira kuti njira yophunzirira makina ingafulumizitse kupanga ndi kuyesa zipangizo za batri. "Tiyerekeze kuti muli ndi chipangizo chatsopano, ndipo mumachiyendetsa kangapo. Mutha kugwiritsa ntchito njira yathu yodziwira nthawi yake, kenako ndikupanga zisankho ngati mukufuna kupitiliza kuchiyendetsa mwachisawawa kapena ayi."

"Ngati ndinu wofufuza mu labu, mutha kupeza ndikuyesa zinthu zambiri munthawi yochepa chifukwa muli ndi njira yachangu yoziwunikira," adatero Babinec.

Pepala lochokera pa kafukufukuyu, “Ukadaulo wa zinthu zophunzirira makina wathandiza kuneneratu nthawi ya batri,” inatuluka mu magazini ya pa intaneti ya pa February 25 ya Journal of Power Sources.

Kuwonjezera pa Paulson ndi Babinec, olemba ena a pepalali ndi Joseph Kubal, Logan Ward, Saurabh Saxena ndi Wenquan Lu a ku Argonne.

Kafukufukuyu adathandizidwa ndi ndalama zothandizira za Argonne Laboratory-Directed Research and Development (LDRD).
