Inyigisho isanga urufunguzo rwo kuzamura ubuzima bwa bateri: Imikoranire hagati yuduce

Nk’uko ibitangazamakuru byo mu mahanga bibitangaza, Feng Lin, umwarimu wungirije mu ishami rya chimie muri kaminuza ya siyansi y’ubumenyi ya Virginia Tech, hamwe n’itsinda rye ry’ubushakashatsi basanze kwangirika kwa batiri hakiri kare bigaragara ko biterwa n’imiterere y’uduce duto twa electrode, ariko nyuma y’ibirego byinshi. Nyuma yo kuzunguruka, uburyo ibyo bice bihurira hamwe ni ngombwa.

Lin yagize ati: "Ubu bushakashatsi bugaragaza amabanga y'uburyo bwo gukora no guhimba electrode ya batiri mu gihe kirekire cya bateri."Kugeza ubu, laboratoire ya Lin irimo gukora ku buryo bushya bwo kongera amashanyarazi ya batiri kugirango ikore amashanyarazi yihuse, ahendutse, ubuzima burebure hamwe n’imyubakire ya electrode yangiza ibidukikije.

Inyigisho isanga urufunguzo rwo kuzamura ubuzima bwa bateri: Imikoranire hagati yuduce

Nk’uko ibitangazamakuru byo mu mahanga bibitangaza, Feng Lin, umwarimu wungirije mu ishami rya chimie muri kaminuza ya siyansi y’ubumenyi ya Virginia Tech, hamwe n’itsinda rye ry’ubushakashatsi basanze kwangirika kwa batiri hakiri kare bigaragara ko biterwa n’imiterere y’uduce duto twa electrode, ariko nyuma y’ibirego byinshi. Nyuma yo kuzunguruka, uburyo ibyo bice bihurira hamwe ni ngombwa.

Lin yagize ati: "Ubu bushakashatsi bugaragaza amabanga y'uburyo bwo gukora no guhimba electrode ya batiri mu gihe kirekire cya bateri."Kugeza ubu, laboratoire ya Lin irimo gukora ku buryo bushya bwo kongera amashanyarazi ya batiri kugirango ikore amashanyarazi yihuse, ahendutse, ubuzima burebure hamwe n’imyubakire ya electrode yangiza ibidukikije.

Inkomoko y'amashusho: Feng Lin

Lin yagize ati: "Iyo ubwubatsi bwa electrode butuma buri gice kigira icyo gisubiza vuba ku bimenyetso by'amashanyarazi, tuzaba dufite agasanduku gakomeye ko gukoresha bateri vuba".Ati: “Twishimiye ko dushobora gusobanukirwa n'igisekuru kizaza cya bateri zihenze cyane.”

Ubushakashatsi bwakozwe ku bufatanye na Minisiteri ishinzwe ingufu muri Leta zunze ubumwe za Amerika muri Laboratwari yihuta ya SLAC, kaminuza ya Purdue ndetse n’ikigo cy’ibihugu by’i Burayi cyitwa Synchrotron.Zhengrui Xu na Dong Ho, bagenzi ba postdoctoral muri laboratoire ya Lin, nabo ni abanditsi ku mpapuro, bayobora ibihimbano bya electrode, guhimba bateri, no gupima imikorere ya batiri, no gufasha mu bushakashatsi bwa X-ray no gusesengura amakuru.

Umuhanga mu bya SLAC, Yijin Liu, mugenzi we muri Stanford Synchrotron Radiation Light Source (SSRL) yagize ati:Ati: "Niba ushaka gukora bateri nziza, ugomba kumenya gushyira hamwe."

Mu rwego rw’ubushakashatsi, Lin, Liu na bagenzi be bakoresheje uburyo bwo kureba mudasobwa kugira ngo bige uburyo uduce tumwe na tumwe tugize electrode ya bateri zishishwa zangirika igihe.Intego iki gihe nukwiga ntabwo ari uduce tumwe na tumwe gusa, ahubwo tuniga uburyo bakorana kugirango bagure cyangwa bagabanye ubuzima bwa bateri.Intego nyamukuru nukwiga uburyo bushya bwo kwagura ubuzima bwibishushanyo mbonera.

Mu rwego rwo kwiga, itsinda ryize bateri cathode hamwe na X-ray.Bakoresheje X-ray tomografiya kugirango bongere kubaka ishusho ya 3D ya cathode ya bateri nyuma yuburyo butandukanye bwo kwishyuza.Baca bagabanya aya mashusho ya 3D mubice bikurikirana 2D hanyuma bakoresha uburyo bwo kureba mudasobwa kugirango bamenye ibice.Usibye Lin na Liu, muri ubwo bushakashatsi harimo umushakashatsi w’iposita ya SSRL Jizhou Li, umwarimu w’ubukanishi bwa kaminuza ya Purdue Keije Zhao, n’umunyeshuri wahawe impamyabumenyi muri kaminuza ya Purdue Nikhil Sharma.

Abashakashatsi amaherezo bagaragaje ibice birenga 2000 kugiti cyabo, ntibabaze gusa ibiranga ibice byihariye nkubunini, imiterere, hamwe nubusumbane bwubuso, ariko banagaragaza nkigihe inshuro ibyo bice byahuriraga hamwe nuburyo ibice byahinduye imiterere.

Ubukurikira, barebeye hamwe uko buri mutungo watumye ibice bisenyuka, basanga nyuma yincuro 10 zishyuza, ibintu bikomeye byari imiterere yibice bya buri muntu, harimo nuburyo ibice byerekeranye nuburinganire nuburinganire bwubunini bwubuso.Nyuma yizunguruka 50, ariko, guhuza hamwe nitsinda ryamatsinda byatumaga ibice byangirika - nkuburyo intera zombi zari zitandukanye, uko imiterere yahindutse, ndetse n’uko uduce twinshi tw’umupira wamaguru umupira umeze nkufite icyerekezo kimwe.

Liu yagize ati: "Impamvu ntikiri agace konyine, ahubwo ni imikoranire y'ibice."Ubu bushakashatsi ni ngombwa kuko bivuze ko ababikora bashobora guteza imbere tekinike yo kugenzura iyi mitungo.Kurugero, barashobora gukoresha imirima ya magneti cyangwa amashanyarazi Guhuza ibice birebire hamwe, ubushakashatsi buheruka gukorwa bwerekana ko ibyo bizongera igihe cya batiri. ”

Lin yongeyeho ati: “Twakomeje gukora ubushakashatsi bwimbitse ku buryo bateri za EV zikora neza mu gihe cyihuta kandi n’ubushyuhe buke.Usibye gushushanya ibikoresho bishya bishobora kugabanya ibiciro bya bateri ukoresheje ibikoresho bihendutse kandi byinshi, laboratoire yacu Habayeho kandi imbaraga zihoraho zo gusobanukirwa imyitwarire ya batiri kure yuburinganire.Twatangiye kwiga ibikoresho bya batiri n'ibisubizo byabo ku bidukikije. ”
