Flexible lithium-ion roj teeb

Ib pawg ntawm cov kws tshawb fawb ntawm University of California tau tsim qhov kev sib tw hauv roj teeb thev naus laus zis - ib qho uas yuav tso cai rau ntau lub zog kom khaws cia hauv cov roj teeb uas hloov tau yooj yim, nyias nyias.

Cov roj teeb no yuav tsum tau hloov pauv tsis yog tsuas yog cov neeg siv khoom siv thev naus laus zis xwb tab sis kuj yog cov cuab yeej kho mob. Lawv tau tsim tawm ntawm lithium-ion, uas ua rau lawv zoo ib yam li koj lub roj teeb smartphone. Qhov txawv tshiab yog tias lawv tuaj yeem hloov pauv yam tsis muaj kev tawg. Qhov ntawd yuav ua rau nws siv tau rau yav tom ntej foldable electronics, zoo li qee lub xov tooj Samsung yav tom ntej.

Cov roj teeb tshiab no kuj tsis tshua muaj peev xwm tsim cov dendrites, uas txhais tau hais tias teeb meem kev nyab xeeb yuav dhau los ua ib qho dhau los. Dendrites yog dab tsi ua rau hluav taws kub thiab tawg - ib yam dab tsi txhua lub tuam txhab thev naus laus zis txhawm rau tiv thaiv ntau li ntau tau. Cov dendrites tsim raws li cov roj teeb them thiab tso tawm. Yog tias lawv loj hlob mus kov lub roj teeb lwm yam hlau, ces qhov luv luv tuaj yeem tshwm sim uas yuav ua rau tawg lossis hluav taws.

Cov kws tshawb fawb tsis paub meej tias nws yuav siv sijhawm ntev npaum li cas los ntawm cov qauv mus rau cov khoom lag luam, tab sis peb paub tias cov roj teeb lithium-ion tshiab no yuav muaj kev nyab xeeb dua li cov uas peb muaj tam sim no - thiab kav ntev dua. Qhov kev tshawb pom tau luam tawm hauv phau ntawv xov xwm ACS Nano.

Nws yuav tsum raug sau tseg tias cov kws tshawb fawb ntawm Stanford University thiab MIT tau tshawb pom qhov teeb meem tib yam no ob peb xyoos dhau los, qhia tias txawm tias cov khoom tawv tawv tuaj yeem hloov pauv hauv lub roj teeb thaum rov ua dua (them / tso tawm). Txawm hais tias qhov zoo rau cov neeg siv khoom siv thev naus laus zis, qhov no yog qhov tsis zoo rau cov khoom siv kho mob vim tias feem ntau yog ua los ntawm silicone (uas yog cov khoom siv tau yooj yim tshaj plaws). Cov khoom siv kho mob yooj yim yuav xav tau kev sim ntau ntxiv kom ntseeg tau tias muaj kev nyab xeeb.

Cov roj teeb tshiab kuj tseem xav tias yuav muaj zog dua li cov roj teeb lithium-ion uas twb muaj lawm, txawm tias nws tseem tsis tau paub meej tias qhov no muaj tseeb rau txhua daim ntawv thov. Nws paub tias cov roj teeb yuav hloov tau yooj yim heev thiab muaj peev xwm khoov rau hauv ntau hom yam tsis muaj kev tawg. Pab neeg tshawb fawb tau lees tias ib gram ntawm lawv cov khoom tshiab tuaj yeem khaws ntau lub zog raws li AA roj teeb, tab sis peb yuav tsum tau tos thiab saib seb cov tuam txhab ua li cas nrog cov cuab yeej no ua ntej peb paub tseeb.

Cov kws tshawb fawb tau tsim cov roj teeb lithium-ion uas tawv, hloov tau thiab tsis tshua muaj peev xwm tsim dendrites. Lawv cia siab tias cov roj teeb no yuav siv tau rau hauv cov xov tooj foldable, cov cuab yeej kho mob thiab lwm yam tech. Nws tsis paub tias nws yuav siv sijhawm ntev npaum li cas rau cov roj teeb no los ntawm cov qauv mus rau cov khoom lag luam hauv khw.

Cov thev naus laus zis tshiab tau tsim los ntawm UC Berkeley thiab luam tawm hauv ACS Nano phau ntawv xov xwm . Nws kuj tau tshawb pom los ntawm cov kws tshawb fawb ntawm Stanford University thiab MIT ob peb xyoos dhau los. Cov kev tshawb fawb ntawd tau pom tias txawm tias cov khoom tawv tawv tuaj yeem hloov pauv hauv lub roj teeb thaum rov ua dua (them / tso tawm). Cov kev tshawb pom no yog qhov tsis zoo rau cov khoom siv kho mob, uas feem ntau yog ua los ntawm silicone. Cov khoom siv kho mob yooj yim yuav xav tau kev sim ntau dua ua ntej tau txais kev pom zoo lossis kev lag luam dav.

Cov roj teeb tshiab no tseem xav tias yuav muaj zog dua li cov roj teeb lithium-ion uas twb muaj lawm. Nws tseem tsis tau paub meej yog tias qhov no muaj tseeb rau txhua daim ntawv thov. Pab neeg tshawb fawb tau lees tias ib gram ntawm lawv cov khoom tshiab tuaj yeem khaws ntau npaum li lub roj teeb AA, tab sis peb yuav tsum tau tos thiab saib seb cov tuam txhab ua li cas nrog cov thev naus laus zis no ua ntej peb paub tseeb.
