Ucwaningo luthola ukhiye wokuthuthukisa impilo yebhethri: Ukusebenzisana phakathi kwezinhlayiya

Ngokwemibiko yabezindaba yakwamanye amazwe, uFeng Lin, uprofesa osebenzisana naye eMnyangweni Wezekhemikhali eVirginia Tech College of Science, kanye nethimba lakhe locwaningo bathola ukuthi ukubola kwebhethri kusenesikhathi kubonakala kuqhutshwa yizicucu zezinhlayiya ze-electrode, kodwa ngemuva kwenqwaba yamacala. Ngemuva kokuxhuma, ukuthi lezo zinhlayiya zihlangana kanjani kubaluleke kakhulu.

"Lolu cwaningo luveza izimfihlo zendlela yokuklama nokwenza ama-electrode ebhethri impilo ende yomjikelezo webhethri," kusho uLin. Njengamanje, ilebhu ka-Lin isebenzela ukuklama kabusha ama-electrode ebhethri ukuze kwakhe ukushaja okusheshayo, izindleko eziphansi, Impilo ende kanye nezakhiwo zama-electrode ezinobungani nemvelo.

Ucwaningo luthola ukhiye wokuthuthukisa impilo yebhethri: Ukusebenzisana phakathi kwezinhlayiya

Ngokwemibiko yabezindaba yakwamanye amazwe, uFeng Lin, uprofesa osebenzisana naye eMnyangweni Wezekhemikhali eVirginia Tech College of Science, kanye nethimba lakhe locwaningo bathola ukuthi ukubola kwebhethri kusenesikhathi kubonakala kuqhutshwa yizicucu zezinhlayiya ze-electrode, kodwa ngemuva kwenqwaba yamacala. Ngemuva kokuxhuma, ukuthi lezo zinhlayiya zihlangana kanjani kubaluleke kakhulu.

"Lolu cwaningo luveza izimfihlo zendlela yokuklama nokwenza ama-electrode ebhethri impilo ende yomjikelezo webhethri," kusho uLin. Njengamanje, ilebhu ka-Lin isebenzela ukuklama kabusha ama-electrode ebhethri ukuze kwakhe ukushaja okusheshayo, izindleko eziphansi, Impilo ende kanye nezakhiwo zama-electrode ezinobungani nemvelo.

Umthombo wesithombe: Feng Lin

"Lapho i-electrode architecture ivumela inhlayiya ngayinye ukuthi iphendule ngokushesha kumasignali kagesi, sizoba nebhokisi lamathuluzi elihle lokushaja amabhethri ngokushesha," kusho uLin. “Sijabulile ukunika amandla ukuqonda kwethu isizukulwane esilandelayo samabhethri ashaja ngokushesha angabizi kakhulu. ”

Ucwaningo lwenziwe ngokubambisana ne-SLAC National Accelerator Laboratory yoMnyango Wezamandla wase-US, iNyuvesi yasePurdue kanye ne-European Synchrotron Radiation Facility. U-Zhengrui Xu no-Dong Ho, ozakwabo be-postdoctoral elebhu ka-Lin, bangababhali ababambisene nabo ephepheni, abahola phambili ekwakhiweni kwama-electrode, ukwenziwa kwebhethri, nezilinganiso zokusebenza kwebhethri, futhi basiza ngokuhlolwa kwe-X-ray nokuhlaziywa kwedatha.

"Amabhulokhi wokwakha ayisisekelo yilezi zinhlayiya ezakha ama-electrode ebhethri, kodwa lapho zikhushulwa, lezi zinhlayiya zixhumana zodwa," kusho usosayensi we-SLAC u-Yijin Liu, uzakwabo eStanford Synchrotron Radiation Light Source (SSRL). "Uma ufuna ukwenza amabhethri angcono, udinga ukwazi ukuthi uhlanganisa kanjani izinhlayiya."

Njengengxenye yocwaningo, uLin, uLiu kanye nabanye ozakwabo basebenzisa amasu okubona ngekhompyutha ukuze bafunde ukuthi izinhlayiya ngazinye ezakha ama-electrode amabhethri aphinde ashajwe ziphuka kanjani ngokuhamba kwesikhathi. Umgomo kulesi sikhathi ukufunda hhayi nje izinhlayiya ngazinye, kodwa nezindlela ezisebenzisana ngazo ukuze zandise noma zehlise impilo yebhethri. Umgomo omkhulu uwukufunda izindlela ezintsha zokwelula impilo yemiklamo yebhethri.

Njengengxenye yocwaningo, ithimba lahlola i-cathode yebhethri ngama-X-ray. Basebenzise i-X-ray tomography ukuze bakhe kabusha isithombe se-3D se-cathode yebhethri ngemva kwemijikelezo ehlukene yokushaja. Babe sebesika lezi zithombe ze-3D zibe uchungechunge lwezingcezu ze-2D futhi basebenzise izindlela zokubona ngekhompyutha ukuhlonza izinhlayiya. Ngaphezu kuka-Lin no-Liu, lolu cwaningo beluhlanganisa nomcwaningi we-SSRL ngemuva kwe-postdoctoral uJizhou Li, uprofesa wezobunjiniyela bemishini eNyuvesi yasePurdue uKeije Zhao, kanye nomfundi oneziqu zasePurdue University uNikhil Sharma.

Abacwaningi bagcina behlonze izinhlayiya ezingaphezu kuka-2,000 XNUMX ngazinye, bengabalanga nje izici zezinhlayiyana ezinjengosayizi, ukwakheka, nobulukhuni bobuso, kodwa futhi izici ezinjengokuthi izinhlayiya zazithintana kangaki kanye nokuthi izinhlayiya zishintshe kangakanani ukwakheka.

Okulandelayo, babheka ukuthi impahla ngayinye ibangele kanjani ukuba izinhlayiya ziqhekeke, futhi bathola ukuthi ngemva kwemijikelezo engu-10 yokushaja, izici ezinkulu kwakuyizakhiwo zezinhlayiya ngazinye, okuhlanganisa ukuthi izinhlayiya zaziyindilinga kangakanani kanye nesilinganiso sevolumu yezinhlayiyana endaweni. Nokho, ngemva kwemijikelezo engu-50, ukubhanqa kanye nezakhiwo zeqembu kwaqhuba ukubola kwezinhlayiyana—njengokuthi zaziqhelelene kangakanani izinhlayiya ezimbili, ukuthi isimo sashintsha kangakanani, kanye nokuthi izinhlayiya ezinde kakhulu ezimise okwebhola lebhola lezinyawo zazinomumo ofanayo.

"Isizathu akuseyona inhlayiya ngokwayo, kodwa ukusebenzisana kwezinhlayiyana," kusho uLiu. Lokhu okutholakele kubalulekile ngoba kusho ukuthi abakhiqizi bangakha amasu okulawula lezi zakhiwo. Isibonelo, bangase bakwazi ukusebenzisa izinkambu kazibuthe noma zikagesi Ukuhlanganisa izinhlayiya ezinde, imiphumela yakamuva iphakamisa ukuthi lokhu kuzonweba impilo yebhethri.”

U-Lin wengeze wathi: “Besicwaninga ngokujulile ukuthi angenza kanjani amabhethri e-EV asebenze kahle ngaphansi kokushaja okusheshayo nezimo zokushisa eziphansi. Ngaphezu kokuklama izinto ezintsha ezinganciphisa izindleko zebhethri ngokusebenzisa izinto zokusetshenziswa ezishibhile neziningi kakhulu, ilabhorethri yethu Kuphinde kwaba nomzamo oqhubekayo wokuqonda ukuziphatha kwebhethri kude nokulinganisa. Sesiqalile ukufunda izinto zebhethri nendlela ezisabela ngayo ezindaweni ezinokhahlo.”
