Ese Ultra-Thin Coated Foil Solutions Yikuba kabiri Umutekano wa Batteri Ikomeye ya Leta?

Indege zitagira abapilote, kugemura ibikoresho bya UAV, hamwe na eVTOL bigenda byihuta cyane muri bateri zikomeye kugirango bigere ku mbaraga zingana na  350 - 400 Wh / kg . Nyamara, indege zitagira abapilote zifite imbaraga nyinshi zisaba kohereza C-umuvuduko mwinshi, kuzamuka cyane, no guhangana n’umuvuduko ukabije wa moteri ( 100 Hz - 1.500 Hz ).

Mugihe amashanyarazi akomeye (SSE) asimbuza ibishashara byaka umuriro, uburyo bukomeye bwo guhuza imiyoboro hagati ya cathode / anode hamwe nibikoresho bisanzwe byegeranya bikomeza kuba intege nke. Gukoresha ultra thin yometse kuri aluminiyumu na fayili y'umuringa 4.5μm - 9μm  substrate hamwe na 0.5μm - 1.5μm ikora neza ) ( -

Imigaragarire ikomeye-Ihuza Ihuza Ikibazo

Bitandukanye na bateri ya electrolyte yamazi isanzwe itose hejuru ya electrode, bateri zikomeye-zishingikiriza rwose kumuvuduko wumubiri kugirango ukomeze umubano:

Micro-Delamination Munsi ya Dynamic Strain: Gukomeza gusohoka cyane-C mugihe cyo gufata indege zitagira abadereva zitanga kwaguka kwumuriro hamwe no guhagarika imashini, bigatera icyuho cyumubiri kumupaka wubu.

Impedance Spikes & Thermal Runaway Triggers: Gusiba bigabanya aho bahurira, gutera imbere imbere (Rᵢₙₜ) kandi bigatera ubushyuhe bwihuse bwangiza ubunyangamugayo bukomeye bwa electrolyte.

Kugereranya: Bare Metal Collector na Ultra-Thin Coated Foil

Sisitemu yo gukusanya ibikoresho

Matrix iri hepfo igereranya abakusanya bambaye ubusa na ultra-thin yometse kuri selile ya bateri ya drone ikomeye:

Ibyingenzi Byumwuga Mubyiza bya Drone Solid-Leta Bateri Porogaramu

Ibibazo

Q1: Kuki bateri-ikomeye ikomeye ikenera ifiriti isize kurusha bateri zisanzwe?

Igisubizo: Batteri ya leta ikomeye ibura electrolytite yuzuye kugirango yuzuze icyuho cya microscopique. Impapuro zometseho zitanga ibintu byoroshye, bikoresha ibyuma bikomeza guhuza umubiri nu mashanyarazi bikomeza guhuza ibice bikomeye mugihe cyo kwaguka no kugabanuka.

Q2: Ese kongeramo igipfundikizo byongera uburemere bwa fili ultra-thin?

Igisubizo: Igifuniko cyongeramo 0.5μm gusa - 1.5 mm ya nano-karubone yoroheje kuruhande ( <1.5 g / m² ). Iyi misa ntoya irarenze kure kugabanya umubyimba wubutaka bwa metero kuva kuri 12 mm kugeza kuri 6 mm , bitanga uburemere bwingirabuzimafatizo ya 5% –8%.

Q3: Nigute fayili isize irinda dendrite muri bateri ya lithium-metal ikomeye?

Igisubizo: Nano-itwara primer itunganya microscopique foil hejuru yuburiganya hamwe na micro-burrs, bigakora umurima w'amashanyarazi umwe rwose. Ibi birinda kwibanda kumurongo utera lithium dendrite nucleation.

Q4: Ni ikihe gipimo ntarengwa cyo gusohora gishobora gukoreshwa na ultra-thin coated foils?

Umwanzuro

Kurera ultra-thin coated foil solutions ikemura ikibazo gikomeye-gikomeye cyimbere yimbere, ikubye kabiri urwego rwumutekano hamwe nubwizerwe bwimikorere ya bateri zikomeye za drone.

Kugirango uhindure ibikoresho byo gukora bateri ya drone:

Gutegeka Micro-Gravure Carbone Yashizwemo Amafiriti: Kugaragaza 0.5μm - 1.0μm nano-karubone primer yatwikiriye kuri 9μm aluminium (cathode) na 4.5μm - 6μm y'umuringa (anode).

Saba 180 ° Kwipimisha Imbaraga Zibishishwa (> 350 N / m): Menya neza ko abakora selile bagenzura electrode-kuri-fayili mbere na nyuma yo kwipimisha kunyeganyega.

Kugenzura Ubuso Bwuzuye & Burr Imipaka (≤ 1m): Gukurikiza byimazeyo ibipimo byo gutema laser kugirango byemeze zeru zeru zishobora kurenga ultra-thin ikomeye ya electrolyte.
