Ibanga ryo kuramba kuri bateri zishishwa zirashobora kuba muburyo butandukanye.Uburyo bushya bwerekana uburyo selile ya lithium-ion muri pack degrade yerekana uburyo bwo kudoda kwishyuza ubushobozi bwa buri selile kugirango bateri za EV zishobore gukemura ibibazo byinshi kandi bikarinda gutsindwa.

Ubushakashatsi, bwatangajwe ku ya 5 Ugushyingo muriIEEE Ihererekanyabubasha kuri tekinoroji ya sisitemu.Inzira yemerera buri selile kubaho neza - kandi ndende - ubuzima.

Nk’uko byatangajwe n'umwarimu wa Stanford akaba n'umwanditsi mukuru w’ubushakashatsi Simona Onori, ibigereranyo byambere byerekana ko bateri zikoreshejwe n’ikoranabuhanga rishya zishobora gukoresha byibura 20% byikurikiranya-bisohora umuriro, kabone niyo byakoreshwa kenshi, bikaba byongera ingufu kuri bateri.

Imbaraga nyinshi zabanjirije imbaraga zo kongera ubuzima bwa bateri yimodoka yamashanyarazi yibanze mugutezimbere igishushanyo, ibikoresho, nogukora ingirabuzimafatizo imwe, hashingiwe kumyumvire yuko, nkumuhuza mumurongo, ipaki ya batiri ni nziza nkakagari kayo gafite intege nke.Ubushakashatsi bushya butangirana no kumva ko nubwo guhuza intege byanze bikunze - kubera gukora udusembwa kandi kubera ko selile zimwe zangirika vuba kurusha izindi kuko zihura nimpungenge nkubushyuhe - ntibakeneye kumanura ibintu byose.Urufunguzo ni uguhuza ibiciro byo kwishyuza kubushobozi budasanzwe bwa buri selile kugirango wirinde gutsindwa.

Onori, umwungirije wungirije ushinzwe ubumenyi bw’ubumenyi bw’ingufu muri Stanford Doerr yagize ati: "Niba bidakemuwe neza, itandukanyirizo rishingiye ku ngirabuzimafatizo rishobora guhungabanya kuramba, ubuzima, n’umutekano by’ipaki ya batiri kandi bigatera gukora nabi hakiri kare." Ishuri ryo Kuramba.Ati: "Uburyo bwacu buringaniza ingufu muri buri kagari kari mu gapaki, kuzana selile zose ku ntego ya nyuma yishyurwa mu buryo bwuzuye kandi tunoza kuramba kw'ipaki."

Yahumekewe kubaka bateri ya kilometero

Bimwe mu byatumye ubushakashatsi bushya bugaruka ku itangazo ryatangajwe na 2020 na Tesla, isosiyete ikora imodoka z'amashanyarazi, ko ikora kuri “bateri ya kilometero imwe.”Iyi yaba bateri ishoboye guha imodoka mumilometero 1 cyangwa irenga (hamwe no kwishyuza bisanzwe) mbere yo kugera aho, nka bateri ya lithium-ion muri terefone ishaje cyangwa mudasobwa igendanwa, bateri ya EV ifite umuriro muke cyane kuburyo udashobora gukora .

Batiyeri irenze garanti isanzwe yabatwara ibinyabiziga byamashanyarazi yimyaka umunani cyangwa kilometero 100.000.Nubwo ipaki ya batiri isanzwe irenze garanti, abaguzi bizeye ibinyabiziga byamashanyarazi birashobora gukomera mugihe abasimbuye bateri bahenze babaye gake cyane.Batare ishobora gukomeza kwishyurwa nyuma yibihumbi n’ibihumbi byongeye kwishyurwa irashobora kandi koroshya inzira yo gukwirakwiza amashanyarazi yamakamyo maremare, no kwemeza uburyo bwitwa ibinyabiziga biva kuri gride, aho bateri ya EV yabika kandi ikohereza ingufu zidasanzwe kuri amashanyarazi.

Onori yagize ati: "Nyuma byaje gusobanurwa ko igitekerezo cya batiri ya kilometero kilometero mu by'ukuri atari chimie nshya, ahubwo ko ari inzira yo gukoresha bateri mu kuyikoresha mu buryo bwuzuye."Ubushakashatsi bujyanye na bwo bwibanze kuri selile imwe ya lithium-ion, muri rusange idatakaza ubushobozi bwo kwishyurwa vuba nkuko paki yuzuye ibikora.

Ishimishijwe, Onori n'abashakashatsi babiri muri laboratoire ye - intiti ya dogiteri Vahid Azimi hamwe n’umunyeshuri wa PhD Anirudh Allam - bahisemo gukora ubushakashatsi ku buryo imicungire y’ubwoko bwa batiri isanzwe ishobora guteza imbere imikorere n’ubuzima bwa paki yuzuye, ishobora kuba irimo selile amagana cyangwa ibihumbi. .

Moderi yo kwizerwa cyane

Nintambwe yambere, abashakashatsi bakoze moderi yubudahemuka ya mudasobwa yimyitwarire ya bateri yerekana neza impinduka zumubiri nubumara bibera imbere muri bateri mubuzima bwayo.Zimwe murizo mpinduka zigaragara mumasegonda cyangwa iminota - izindi mumezi cyangwa imyaka.

Onori, umuyobozi wa Laboratwari ishinzwe ingufu za Stanford yagize ati: "Dukurikije ubumenyi dufite, nta bushakashatsi bwabanje bwakoresheje ubwoko bwa bateri yo mu rwego rwo hejuru, inshuro nyinshi twashizeho."

Gukoresha ibigereranyo hamwe nicyitegererezo byerekana ko ipaki ya batiri igezweho ishobora gutezimbere no kugenzurwa no gutandukanya itandukaniro hagati ya selile ziyigize.Onori na bagenzi be batekereza ko urugero rwabo ruzakoreshwa mu kuyobora iterambere rya sisitemu yo gucunga bateri mu myaka iri imbere ishobora gukoreshwa mu buryo bworoshye mu bishushanyo mbonera by’imodoka.

Ntabwo ibinyabiziga byamashanyarazi bihagaze neza.Onori yavuze ko hafi ya porogaramu iyo ari yo yose “ishimangira ipaki ya batiri” ishobora kuba umukandida mwiza ku micungire myiza imenyeshwa n'ibisubizo bishya.Urugero rumwe?Indege imeze nka drone ifite guhaguruka guhaguruka no guhaguruka, rimwe na rimwe bita eVTOL, ba rwiyemezamirimo bamwe biteze gukora nka tagisi zo mu kirere no gutanga izindi serivisi zigenda mu kirere mu myaka icumi iri imbere.Nubwo bimeze bityo, izindi porogaramu zikoreshwa muri bateri ya lithium-ion zishobora kwishyurwa, harimo indege rusange hamwe nububiko bunini bwingufu zishobora kubaho.

Onori yagize ati: "Batteri ya Litiyumu-ion imaze guhindura isi mu buryo bwinshi."Ati: "Ni ngombwa ko tubona byinshi bishoboka muri ubwo buryo bw'ikoranabuhanga rihindura ndetse n'abasimbuye bazaza."
