Betavolt Technology, ib lub tuam txhab raws li Beijing tau tshaj tawm miniaturization ntawm nuclear roj teeb siv Ni-63 radioisotope thiab pob zeb diamond semiconductor (plaub tiam semiconductor) module.
Nuclear roj teeb (paub ntau yam li atomic roj teeb los yog radioisotope roj teeb lossis radioisotope generator lossis hluav taws xob-voltaic roj teeb lossis Betavoltaic roj teeb) muaj beta-emitting radioisotope thiab semiconductor. Nws tsim hluav taws xob los ntawm kev hloov pauv semiconductor ntawm beta particles (los yog electrons) tawm los ntawm radioisotope nickel-63. Lub Betavoltaic roj teeb (piv txwv li nuclear roj teeb uas siv beta particle emissions los ntawm Ni-63 isotope rau lub hwj chim tiam) thev naus laus zis muaj nyob rau ntau tshaj tsib xyoo caum txij li thawj zaug tshawb pom hauv 1913 thiab niaj hnub siv hauv qhov chaw sector rau hwj chim spacecraft payloads. Nws lub zog ceev yog siab heev tab sis lub zog tso zis tsawg heev. Lub ntsiab kom zoo dua ntawm nuclear roj teeb siv tau ntev, tsis tu ncua fais fab mov rau tsib xyoo lawm.
Cov lus: Hom roj teeb
| Roj teeb tshuaj converts chemical zog khaws cia rau hauv lub cuab yeej rau hluav taws xob. Nws yog lub hauv paus electrochemical cell uas muaj peb lub ntsiab lus - cathode, anode, thiab electrolyte. tuaj yeem siv tau, sib txawv hlau thiab electrolytes tuaj yeem siv tau xws li roj teeb Alkaline, Nickel Hlau Hydride (NiMH), thiab Lithium Ion. Nws muaj tsawg zog ceev tab sis high-power output. |
| Roj roj converts chemical zog ntawm ib tug roj (feem ntau hydrogen) thiab oxidizing tus neeg sawv cev (feem ntau oxygen) rau hauv hluav taws xob. Yog tias hydrogen yog roj, cov khoom tsuas yog hluav taws xob, dej, thiab cua sov. |
| Nuclear roj teeb (kuj hu ua Atomic roj teeb or Radioisotope roj teeb or radioisotope generator los yog Radiation-voltaic roj teeb) converts radioisotope zog los ntawm kev lwj ntawm ib tug radioactive isotopes los tsim hluav taws xob. Nuclear lub roj teeb muaj lub zog siab ceev thiab ntev ntev tab sis muaj qhov tsis zoo ntawm cov khoom tawm hluav taws xob tsawg. Betavoltaic roj teeb: lub roj teeb nuclear uas siv beta emissions (electrons) los ntawm radioisotope. X-ray-voltaic roj teeb siv X-ray hluav taws xob tawm los ntawm cov xov tooj cua isotope. |
Betavolt Technology's tiag tiag innovation yog kev loj hlob ntawm ib leeg-crystal, plaub-tiam pob zeb diamond semiconductor ntawm 10 microns thickness. Pob zeb diamond yog qhov tsim nyog rau kev siv vim nws qhov sib txawv loj ntawm ntau dua 5eV thiab hluav taws xob tsis kam. High-efficiency pob zeb diamond converters yog tus yuam sij rau kev tsim cov roj teeb nuclear. Radioisotope Ni-63 nplooj ntawv ntawm 2-micron thickness yog muab tso rau ntawm ob pob zeb diamond semiconductor converters. Lub roj teeb yog modular muaj ob peb yam ywj siab. Lub roj teeb lub zog yog 100 microwatts, qhov voltage yog 3V thiab qhov ntev yog 15 X 15 X 5 hli3.
Lub tuam txhab Asmeskas Widetronix lub roj teeb betavoltaic siv silicon carbide (SiC) semiconductor.
BV100, lub roj teeb me me nuclear, tsim los ntawm Betavolt Technology yog tam sim no nyob rau hauv pilot theem thiab tej zaum yuav nkag mus rau loj ntau lawm theem nyob ze yav tom ntej. Qhov no tuaj yeem pom kev siv hluav taws xob AI, khoom siv kho mob, MEMS systems, sensors siab heev, me me drones thiab micro-robots.
Xws li cov khoom siv hluav taws xob me me me yog xav tau ntawm lub sijhawm saib ntawm kev nce qib hauv nanotechnology thiab electronics.
Betavolt Technology npaj yuav tso lub roj teeb nrog lub zog ntawm 1 watt hauv 2025.
Ntawm cov ntaub ntawv ntsig txog, kev tshawb fawb tsis ntev los no tau tshaj tawm txog X-ray hluav taws xob-voltaic (X-ray-voltaic) roj teeb uas muaj txog li peb npaug ntawm lub zog tso zis ntau dua li ntawm lub xeev-of-the-art betavoltaics.
