Ese Lacquered Urupapuro rwa aluminiyumu Inzitizi Yubushyuhe Bwinshi Kurwanya Bateri ya eVTOL Amashanyarazi?

Indege ihagaritse guhaguruka no guhaguruka (eVTOL) bisaba ipaki ya batiri ya lithium-ion ikora cyane kuri voltage ikabije kandi nigipimo cyihuta cyo gusohoka. Kuri ubwo bucucike bw'amashanyarazi, kunanirwa gukabije kw'akagari kamwe - guterwa no gutembera imbere mu gihe gito, gutobora imashini, cyangwa gukabya gukabya gukabije - birashobora kurekura ubushyuhe bw’ubushyuhe hamwe n'ubushyuhe bwaho burenga 1.000 ° C.

Mugihe ifu mbisi yonyine idashobora kwihanganira indege ndende ya plasma, Ubushyuhe bwo hejuru cyane bwa aluminiyumu yometse kumurongo wa ceramic-airgel ikora nkibyingenzi byingenzi byibanze byumuriro wa flame, ibyuma byerekana ubushyuhe, hamwe nimbogamizi yumuriro wa gazi muri bateri igezweho ya eVTOL selile-selile na sisitemu yo kwigunga.

Ubukanishi bwo gukwirakwiza Ubushyuhe

Iyo umufuka mwinshi ufite ingufu nyinshi cyangwa selile ya lithium-ion ya selile yinjiye mumashanyarazi, reaction ya exothermic chain reaction:

Kurekura Ubushyuhe Bwihuse (> 1000 ° C): Kubora cathode nibikoresho bya electrolyte birekura ingufu zumuriro mwinshi mumasegonda.

Gucana umuriro wa gaz: Gushyuha cyane hamwe na gaze ya hydrogène ihumeka kumuvuduko mwinshi, itwara uduce duto twa soot.

Kunanirwa kwa Module Kunanirwa: Hatabayeho inzitizi zikomeye ziterwa nubushyuhe bwumuriro, ubushyuhe bwumuriro hamwe na gaze byihuta bikurura selile zituranye, bikaviramo gutakaza burundu.

Ububiko bwa Thermal Barrier Ubwubatsi: Urupapuro rwa aluminiyumu + Core Organic

Lacquered aluminium foil ikora nkuruhu rwinyuma rwimbere muri barrière yumuriro.

Urupapuro rwo hanze rwerekana imirasire ya infragre kandi rukabuza kwinjira muri gaze, mugihe imbere ya airgel yimbere igabanya ihererekanyabubasha ryogukwirakwiza ubushyuhe, bigatuma selile zituranye ziri munsi yubushyuhe bukabije.

Ibikoresho bya tekinike Matrix: Inzitizi ya Bateri Yacitse Urupapuro rwa aluminiyumu

Imbonerahamwe ikurikira irerekana ibipimo bya tekiniki ya feri ya aluminiyumu ikoreshwa muri batiri ya eVTOL ipakira inzitizi zumuriro:

Ibyiza byimikorere muri Bateri ya eVTOL Ubushyuhe bwo guhunga

Ibibazo

Q1: Fayili ya aluminiyumu yonyine ishobora guhagarika ingirabuzimafatizo ya selile?

Igisubizo: Nta kintu na kimwe gihagarika ubushyuhe bwumuriro. Ifumbire ya aluminiyumu ikora nk'ingabo ya flame idashobora kwangirika hamwe nubushuhe bwerekana ubushyuhe muri sisitemu igizwe n’ibice byinshi (bihujwe na aerogels, mika, cyangwa fibre ceramic) kugirango birinde gukwirakwiza ubushyuhe mu ngirabuzimafatizo zituranye.

Q2: Ni ukubera iki ifiriti ya lacquer ikunzwe kuruta feri ya aluminiyumu idahwitse muri bariyeri ya batiri?

Igisubizo: Ifu ya aluminiyumu ishonga igera kuri 660 ° C kandi ntabwo itanga amashanyarazi. Lacquer yubushyuhe bwo hejuru yongeramo imbaraga zingenzi zo kurwanya dielectric, kongera igihe cyigihe gito cyo kubaho kwumuriro, kandi ikarinda fayili kwirinda aside hydrofluoric (HF).

Q3: Nigute feri ya aluminiyumu ikora mugihe cyo guhumeka gazi nyinshi?

.Igisubizo

Q4: Ese gukata laser bizangiza kwangiza lacquer kuri feri ya batiri yoroheje?

Igisubizo : No.

Q5: Nigute kurwanya flame bigeragezwa kuri bateri yo mu rwego rwa bateri?

Igisubizo: Imikorere yubushyuhe yemejwe hakoreshejwe ibizamini bya flame itaziguye (UL 94 V-0 / ISO 2685), isesengura ry’ubushyuhe bw’umuriro (TGA), igeragezwa rya dielectric yamenetse ( ASTM D149), hamwe n’ibizamini byuzuye byo gukwirakwiza amashyanyarazi mu bikoresho bya batiri bizima.

Umwanzuro

Kwishyira hamwe feri ya aluminiyumu yometse kuri bariyeri ikomatanya ituma abajenjeri ba batiri ba eVTOL bujuje ibyangombwa bikoreshwa mu ndege bikoreshwa mu kirere mu gihe bagabanya uburemere bw'ipaki.

Kugirango uhindure ibikoresho byatoranijwe kuri sisitemu yumutekano wa bateri:

Hitamo Foil Gauge ukoresheje Umuvuduko wa Flame: Koresha 0.02mm - 0.04mm foil kugirango uhindure pouch selile selile selile selile selile; vuga 0.05mm - 0,10mm foil kumashanyarazi yumuvuduko ukabije wa selile hejuru-gutwikira ingabo.

Manda Yagenzuwe Ubushyuhe & Dielectric Ibipimo: Menya neza ko lacquer zihariye zigera kuri UL 94 V-0 flame kandi zigatanga ingufu za dielectric byibura ≥ 1.5 kV / mm.
