Key Takeaways
- Quantum roj teeb tuaj yeem muaj ib hnub hloov pauv kev lag luam los ntawm kev muab qhov me me thiab them sai dua.
- Tab sis ib tus kws tshaj lij hais tias quantum roj teeb yuav yog "xyoo lossis ntau xyoo" kom deb ntawm koj lub xov tooj ntawm tes.
- Kev cog lus kev tshawb fawb tab tom ua kom tau ntau dua ntawm Li-Ion roj teeb chemistry.
Koj cov khoom siv tuaj yeem muaj ib hnub tau txais lub zog tseem ceeb ua tsaug rau quantum mechanics.
Cov kws tshawb fawb tau tshaj tawm qhov kev ua tiav hauv quantum roj teeb uas thaum kawg tuaj yeem hloov pauv cov khoom siv ua haujlwm li cas. Quantum roj teeb yuav me me thiab them sai dua li cov roj teeb tam sim no. Cov thev naus laus zis tshiab tsuas yog ib txoj hauv kev uas kev lag luam roj teeb tau npaj rau kev rov xav dua.
"Los ntawm qhov kev xav ua haujlwm tau zoo, peb xav tau cov khoom siv sib zog nrog kev cia ntau dua, thiab cov roj teeb tshiab tuaj yeem them taus peb ob leeg," Mark Falinski, tus kws tshawb fawb txog kev ruaj ntseg ib puag ncig uas tsis yog ib feem ntawm txoj kev tshawb fawb tsis ntev los no, hais rau Lifewire hauv ib qho email interview.
Schrödinger's Roj teeb?
Cov kws tshawb fawb ntawm University of Adelaide hauv Australia tau lees tias lawv tau ua ib kauj ruam tseem ceeb hauv kev ua cov roj teeb quantum kom muaj tseeb. Lawv hais tias lawv tau ua pov thawj lub tswv yim ntawm kev nqus super, lub tswv yim tseem ceeb hauv qab lub roj teeb quantum, raws li kev tshawb fawb tsis ntev los no luam tawm hauv phau ntawv Journal Science Advances.
"Quantum roj teeb, uas siv quantum mechanical hauv paus ntsiab lus los txhim kho lawv lub peev xwm, yuav tsum tau them lub sij hawm tsawg dua qhov lawv tau txais," James Q. Quach, ib tus kws sau ntawv tshawb fawb, tau hais hauv xov xwm tshaj tawm. "Nws yog qhov kev xav tau tias lub zog them lub zog ntawm quantum roj teeb nce nrawm dua li qhov loj ntawm lub roj teeb, uas tuaj yeem tso cai rau txoj hauv kev tshiab kom them sai sai."
Txhawm rau ua pov thawj lub tswv yim ntawm kev nqus tau zoo, pab pawg tsim wafer-zoo li microcavities ntawm ntau qhov sib txawv uas muaj cov organic molecules. Txhua microcavity raug them siv lub laser.
"Cov txheej txheem nquag ntawm microcavity muaj cov khoom siv hluav taws xob uas muaj cov khoom siv hluav taws xob uas khaws lub zog. Hauv qab cov txiaj ntsig super absorbing ntawm quantum roj teeb yog lub tswv yim tias tag nrho cov molecules ua ke los ntawm cov cuab yeej hu ua quantum superposition," said Quach..
Quantum superposition, lub hauv paus ntsiab lus ntawm quantum mechanics, hais tias zoo li nthwv dej hauv classical physics, ob lub xeev quantum tuaj yeem muab ntxiv ua ke ("superposed"), thiab qhov tshwm sim yuav yog lwm lub xeev quantum siv tau.
Tab sis Falinkski ceeb toom tias quantum roj teeb yuav yog "xyoo lossis ntau xyoo" kom deb ntawm koj lub xov tooj ntawm tes.
"Qhov tau hais tias, muaj ntau qhov kev nqis peev uas tau muab tso rau hauv quantum xam qhov chaw, thiab yog tias cov kev nqis peev tib yam no raug thawb ua ntej hauv quantum roj teeb, peb tuaj yeem ua tiav qhov kev vam meej sai dua," nws hais ntxiv..
Peb tab tom mus txog qhov kev txwv ntawm qhov peb cov roj teeb tuaj yeem khaws thiab rov siv dua.
Powering Innovations
Kev xav tau ntawm lub roj teeb tshiab yog qhov zoo. Los ntawm 2040, lub zog siv los ntawm tib neeg yuav tsum tau nce 28 feem pua los ntawm 2015 qib. Feem ntau ntawm lub zog tseem yuav los ntawm fossil fuels nrog cov nqi cuam tshuam rau ib puag ncig.
"Peb tab tom mus txog qhov kev txwv theoretical ntawm qhov peb cov roj teeb tuaj yeem khaws thiab rov siv dua," Falinski tau hais. "Lithium-Ion roj teeb tau zoo dua thiab zoo dua, tab sis peb tau mus txog qhov chaw uas lub cev thiab chemistry tsis tuaj yeem txhim kho lawv ntau ntxiv."
-Kev Tshawb Fawb Kev Tshawb Fawb yuav tau txais cov khoom siv roj teeb li-Ion, suav nrog cov theem ntawm kev txhim kho, Craig Lawrence, tus neeg ua lag luam huv huv uas muaj keeb kwm yav dhau los hauv kev lag luam roj teeb, hais rau Lifewire hauv kev xam phaj email.
Cov roj teeb lub xeev, lub roj teeb lithium-hlau thev naus laus zis, tuaj yeem muab lub zog muaj zog ntau dua li lithium-Ion, Lawrence tau hais.
"Peb muaj ze li ntawm kev suav tsis kawg hauv peb lub hnab ris, tab sis nws tseem muaj txiaj ntsig ntev npaum li lub roj teeb tuaj yeem ua kom nws khiav, "nws hais ntxiv. "Nws yog vim li cas peb tsis tuaj yeem muaj lub xov tooj smartphone uas kav ntev dua ib hnub ntawm kev them nqi lossis lub drone uas tuaj yeem siv sijhawm ntev dua 30-60 feeb."
E-tsheb tuam yog lwm qhov chaw uas xav tau lub roj teeb hloov kho dua tshiab. Xyoo 2021, New York City ib leeg tau tshaj tawm ntau dua 80 qhov hluav taws kub txuas nrog lub tsheb kauj vab hluav taws xob thiab lawv cov roj teeb. ZapBatt tau tsim lub lithium-titanate e-tsheb tuam roj teeb uas nws hais tias yog hluav taws kub resistant thiab tuaj yeem them tag nrho ntawm 0% mus rau 100% hauv 20 feeb es tsis txhob siv li 6 teev.
"Rau ib tus neeg siv khoom, tos rau 6 teev kom them roj teeb thiab xav tau hloov roj teeb txhua xyoo yog qhov tsis yooj yim thiab tsis zoo rau eco," Charlie Welch, CEO ntawm ZapBatt, hais rau Lifewire hauv kev sib tham hauv email. "Nrog rau qhov kev nce siab loj hauv e-bike kev txaus siab, lub roj teeb thev naus laus zis yuav tsum hloov zuj zus los txhawb kev siv ntau dua thiab txhim kho kev nyab xeeb."
