Key Takeaways
- Roj teeb ua nrog graphene tuaj yeem ua rau kom nrawm dua.
- Elecjet hais tias nws cov roj teeb Apollo Ultra tshiab tuaj yeem sau rau hauv ib nrab teev.
- Cov kws tshawb fawb tau ua haujlwm ntawm ntau qhov kev cog lus roj teeb chemistry thiab thev naus laus zis, suav nrog nanomaterials.
Koj tsis ntev yuav tsis tau tos ib puag ncig kom koj cov khoom siv them nqi.
Elecjet tau lees tias nws yuav los tom ntej Apollo Ultra roj teeb tuaj yeem sau nws lub peev xwm 10,000mAh hauv ib nrab teev. Cov roj teeb siv graphene kom xa cov kev them nyiaj ceev ceev thiab ua haujlwm ntev. Nws yog ib feem ntawm kev hloov pauv tsis tu ncua roj teeb thev naus laus zis uas tuaj yeem txhim kho txhua yam ntawm cov xov tooj mus rau lub tsheb fais fab.
"Cov roj teeb muaj peev xwm siab dua thiab txhim khu kev qha ntau dua txhais tau tias peb lub laptops, xov tooj ntawm tes, watches, headphones, thiab tag nrho peb lwm yam khoom siv hluav taws xob txuas ntxiv yuav kav ntev dua thiab ua tau zoo dua," piav qhia Bob Blake, tus lwm thawj ntawm lub cuab yeej Chaw tsim tshuaj paus Fi, hauv kev xam phaj email. "Qhov zoo dua peb cov roj teeb ua tau zoo, qhov ntau peb muaj peev xwm ua neej nyob tsis muaj qhov hluav taws xob ntawm phab ntsa."
YGraphene Booster
Graphene yog ib hom carbon uas tsim los ntawm txheej ntawm atoms txheej txheem nyob rau hauv ob-dimensional honeycomb nanostructure. Cov ntaub ntawv tau piav qhia hauv 2004 los ntawm Andre Geim thiab Konstantin 'Kostya' Novoselov, ua haujlwm ntawm University of Manchester. Pab neeg no tau txais Nobel nqi zog rau Physics hauv 2010.
Graphene tuaj yeem them sai dua thiab kav ntev dua piv rau lithium-ion roj teeb, Elecjet hais. Lub $65 Apollo Ultra roj teeb yuav tsum xa tuaj thaum ntxov xyoo tom ntej.
"Lub graphene composite cell tsis yog lub roj teeb ntshiab graphene," Elecjet tau sau rau ntawm nws lub vev xaib. "Txoj kev xav, nws tseem yog lithium roj teeb tab sis nrog cov khoom siv graphene sib xyaw ntxiv rau cov khoom siv hluav taws xob zoo kom nce cov haujlwm. Ntawm qhov tsis zoo graphite, saum npoo yog coated nrog txheej txheej ntawm graphene, uas txo impedance."
Futuristic Roj Teeb Tech ntawm Txoj Kev
Cov kws tshawb fawb tau ua haujlwm ntawm ntau qhov kev cog lus roj teeb thiab thev naus laus zis, suav nrog nanomaterials, Donovan Wallace, tus lwm thawj ntawm electronics ntawm Design 1st, hais rau Lifewire hauv kev xam phaj email.
"Cov kev nce qib no, ua ke nrog kev txhim kho roj teeb thev naus laus zis thiab kev sau lub zog, tuaj yeem ua rau qee qhov IoT thiab cov khoom siv ntawm tus kheej pom kev txhim kho ntawm ob mus rau plaub npaug ntawm lub sijhawm ntawm kev them nqi," nws hais. "Lub roj teeb ntev ntev no tsis yog tsuas yog zoo dua rau cov neeg siv tab sis kuj rau ib puag ncig."
Ian Hosein, tus xibfwb ntawm Syracuse University, piv txwv li, tab tom tshawb fawb cov ntaub ntawv uas tuaj yeem siv rau cov roj teeb tom ntej. Cov khoom siv tam sim no feem ntau siv cov roj teeb lithium-ion rechargeable, thev naus laus zis uas tau ua lag luam thawj zaug thaum xyoo 1990s. Tab sis Lithium tuaj yeem raug nqi kim, nyuaj rau rov siv dua, thiab cov roj teeb lithium tuaj yeem muaj teeb meem nrog overheating.
Hosein thiab nws pab neeg tau kawm ntau cov ntaub ntawv xws li calcium, txhuas, thiab sodium kom pom tias lawv tuaj yeem siv los tsim cov roj teeb tshiab li cas.
"Yog tias koj xav thawb lub tsheb fais fab, koj yuav tsum ua kom nws tuaj yeem xa tau ntau lub zog thiab them nqi sai," Hosein tau hais hauv xov xwm tshaj tawm. "Qhov ntawd yog cov lus nug tseem ceeb ntawm kev tshawb fawb. Nws yuav tsum tau ua tib zoo tshawb fawb thiab txhim kho ntawm cov khoom sib txawv uas tuaj yeem them thiab khaws cov ions."
Kev txhim kho rau cov roj teeb lithium-ion uas twb muaj lawm tuaj yeem ua rau cov khoom siv txhawb zog. Ceylon Graphite yog ib lub tuam txhab tsim cov graphite ntuj thiab tshawb nrhiav kev xaiv rau cov tsheb fais fab thiab roj teeb cia.
"Peb tab tom pom kev nce qib hauv lithium-ion roj teeb chemistry, qee qhov kev hloov pauv hauv cathode chemistry, ntau nickel, tsawg cob alt, thiab lwm yam," Ceylon Graphite tus thawj coj Donald Baxter hais rau Lifewire. "Hauv anode, peb tab tom pom qee qhov kev txhim kho rau cov graphite siv me me ntawm silicon. Cov kev nce qib no ua rau lub neej ntev ntawm lub roj teeb nrog rau cov nqi ntev dua. Qee qhov kev nce qib ua rau lub roj teeb muaj peev xwm them taus. sai dua."
Tab sis tsis txhob cia siab tias yuav pom kev nce qib loj hauv roj teeb lub neej txhua lub sijhawm sai sai, ceeb toom tus kws tshaj lij thev naus laus zis Robert Heiblim hauv kev sib tham email nrog Lifewire.
"Muaj ntau 'kev tshaj tawm' ntawm 'kev tawg' hauv roj teeb chemistry ntau xyoo," nws hais. "Txawm li cas los xij, tau txais cov no los ua cov khoom tsim tawm ntau thiab ua haujlwm ntawm qhov ntsuas tau ua pov thawj nyuaj dua li kev ua qauv qhia hauv chav kuaj. kev daws teeb meem."
