- Kev tsim khoom yog cov khoom muag muag thiab ncab uas hloov txav mus rau hauv hluav taws xob thiab tuaj yeem ua haujlwm hauv qhov chaw ntub dej.
- Cov kws tshawb nrhiav tab tom sib tw los nrhiav txoj hauv kev tshiab los tsim hluav taws xob rau tus kheej.
Koj cov cuab yeej siv tau tom ntej no yuav tsis xav tau lub zog sib cais, ua tsaug rau kev nce qib hauv kev tshawb fawb roj teeb.
Cov kws tshawb fawb tau tsim cov khoom muag muag thiab ncab uas hloov txav mus rau hauv hluav taws xob thiab tuaj yeem ua haujlwm hauv qhov chaw ntub dej. Lub invention tuav cov lus cog tseg rau powering wearable devices, them lawv tus kheej tsis tas yuav muaj lub hwj chim sab nraud. Nws yog ib feem ntawm kev siv zog loj zuj zus los nrhiav txoj hauv kev tshiab los tsim hluav taws xob rau tus kheej.
"Lub roj teeb tseem ceeb rau tus kheej hluav taws xob yog cov roj teeb lithium-ion, uas yog cov roj teeb zoo tshaj plaws rau peb caug xyoo," Bingqing Wei, tus thawj coj ntawm Lub Chaw Rau Roj Cells thiab Roj Teeb ntawm University of Delaware, hais rau Lifewire hauv kev xam phaj email. Wei tsis koom nrog kev tshawb fawb tshiab.
"Txawm li cas los xij, niaj hnub no cov roj teeb Li-ion raug teeb meem kev nyab xeeb thiab muaj peev xwm tsawg," Wei ntxiv.
Txoj kev them nyiaj
North Carolina State University cov kws tshawb fawb vam tias lawv qhov kev tsim kho tshiab tuaj yeem daws qee qhov kev txwv ntawm cov cuab yeej siv roj teeb tam sim no. Lub plawv ntawm lub zog harvester lawv tsim yog cov kua hlau alloy ntawm gallium thiab indium. Cov hlau yog encased nyob rau hauv ib tug hydrogel - ib tug mos mos, elastic polymer o nrog dej, raws li ib tug tsis ntev los no tsab ntawv luam tawm.
"Lub zog siv hluav taws xob-xws li lub zog kinetic ntawm cua, nthwv dej, lub cev txav, thiab kev co ntawm lub cev muaj zog-muaj ntau," Michael Dickey, ib tus kws sau ntawv, tau hais hauv xov xwm tshaj tawm. "Peb tau tsim ib lub cuab yeej uas tuaj yeem hloov kho hom kev txav mus rau hauv hluav taws xob. Thiab ib qho ntawm nws cov cwj pwm zoo tshaj plaws yog tias nws ua haujlwm zoo kawg nkaus hauv qab dej."
Cov kws tshawb fawb tab tom ua haujlwm rau lwm qhov haujlwm los txhawb cov khoom siv hluav taws xob los ntawm kev ua kom cov khoom siv hluav taws xob ntau ntxiv.
roj teeb Innovations
Cov kws tshawb fawb thoob ntiaj teb tab tom sib tw los nrhiav txoj hauv kev tshiab rau hluav taws xob hluav taws xob, Chibueze Amanchukwu, tus xibfwb ntawm molecular engineering ntawm University of Chicago, hais rau Lifewire hauv kev xam phaj email. Ib txoj hauv kev yog txhawm rau txhawb lub zog ceev ntawm cov roj teeb kom nce roj teeb lub neej.
"Cov haujlwm no tsom mus rau kev hloov graphite hauv roj teeb nrog silicon thiab lithium hlau," Amanchukwu hais. "Los daws qhov kev txhawj xeeb txog kev nyab xeeb, cov kws tshawb fawb zoo li kuv xav ua kom hloov cov kua hluav taws xob thiab cov dej txaus ntshai hauv lub roj teeb uas tsis muaj hluav taws xob-xeev versions."
Kev tsim kho tshiab hauv roj teeb thev naus laus zis tuaj yeem ua rau cov khoom siv hluav taws xob tshiab thiab txhim kho tus kheej uas tsis tuaj yeem ua tau niaj hnub no, Amanchukwu tau hais.
"Cov cuab yeej yuav muaj kev nyab xeeb dua thiab nyob ntev dua, txhais tau tias lawv tuaj yeem ua si lossis ua haujlwm ntau dua," nws hais ntxiv. "Cov roj teeb hloov tau kuj tseem tso cai rau cov khoom siv ntawm tus kheej uas ua tau zoo dua rau lub cev (xav tias Apple Watch hloov tau tiag tiag) thiab tuaj yeem ua lub zog 'cov khaub ncaws ntse' thiab cov khoom siv IoT ntse."
Tus yuam sij rau cov thev naus laus zis tshiab roj teeb yog txhua yam hais txog kev ua haujlwm zoo dua ntawm tib lub tsev, Amionx CEO Jenna King hais rau Lifewire hauv kev sib tham email.
"Qhov no yog vim li cas peb pom ntau lub tuam txhab tsom mus rau kev txhim kho kev nyab xeeb ntawm cov roj teeb no ib yam nkaus," King ntxiv. "Hauv qhov tseeb, lub roj teeb dhau los ua lub foob pob muaj zog dua hauv tib lub pob."
Cov roj teeb zoo dua rau yav tom ntej zoo dua
Ib hom roj teeb tshiab siv cov ntaub ntawv nano silicon hloov cov khoom siv anode (tsis zoo electrode) hauv cov roj teeb lithium-ion.
"Qhov no tso cai rau lub roj teeb muaj zog dua, tab sis nws kuj txhais tau tias lub roj teeb ua rau muaj kev pheej hmoo loj dua," King hais. "Tseem muaj kev nce qib hauv cov roj teeb lithium hlau rechargeable uas tseem ua kom muaj zog ceev. Kev lag luam tab tom sim kov yeej cov teeb meem nrog lub voj voog lub neej hauv cov roj teeb no nrog rau lub caij nyoog rau hluav taws kub lossis tawg."
Lub roj teeb yav tom ntej tuaj yeem pab daws teeb meem kev nyab xeeb kev hloov pauv, Francis Wang, CEO ntawm NanoGraf Technologies, cov khoom siv roj teeb siab heev pib, hais rau Lifewire hauv kev xam phaj email.
"Cov roj teeb zoo dua yuav ua rau muaj ntau dua thiab nrawm dua ntawm cov tsheb hluav taws xob, raws li kev ua tau zoo thiab nqe lus raws li cov neeg siv khoom xav tau," Wang ntxiv. "Cov roj teeb txhim kho kuj tseem yuav ua rau lub sijhawm tshiab ntawm daim phiaj-teev lub zog ntom ntom uas cov roj teeb yuav pab kom sib npaug ntawm kab sib chaws thiab txhawb nqa qis qis dua."
