Moto wa Lithium Ion Battery: Choopseza Kutumiza Chidebe

Kuchokera mu 2015 kudzapereka zochitika pafupifupi 250 zokhudzana ndi moto wamagetsi wa hoverboard zalembedwa malinga ndi United States Consumer Product Safety Commission. Commission yomweyo akuti ma batri apakompyuta a 83,000 Toshiba adakumbukiridwa mu 2017 chifukwa chamoto ndi chitetezo.

Mu Januwale 2017 galimoto yonyamula zinyalala ya NYC ndiyomwe idadabwitsa oyandikana nawo pomwe batire ya Lithium ion idaphulika mu kompakitala wa galimotoyo. Mwamwayi palibe amene anavulala.

Malinga ndi kafukufuku wopangidwa ndi nthambi ya National Fire Data Center ya US Fire Administration, pakati pa Januware 2009 ndi 31 Disembala 2016 zomwe zachitika 195 za moto wa E-Cigarette zidachitika ku US 133 za izi zomwe zidabweretsa kuvulala.

Zomwe malipoti onsewa amagawana, ndikuti chomwe chimayambitsa chochitika chilichonse ndi mabatire a lithiamu-ion. Mabatire a Lithium Ion asanduka gawo lofunikira pamoyo watsiku ndi tsiku. Omwe amagwiritsidwa ntchito pamakompyuta athu, mafoni am'manja, magalimoto, ngakhale e-ndudu, pali zinthu zochepa zamagetsi zomwe sizigwiritsa ntchito mabatire apamwamba kwambiri. Kutchuka ndikosavuta, batire yabwinoko yaying'ono. Malinga ndi Australian Academy of Science, mabatire a LI ndi olimba kuwirikiza kuposa batire ya NiCad yachikhalidwe.

Kodi mabatire a Lithium Ion amagwira ntchito bwanji?
Malinga ndi dipatimenti yamagetsi: "Batire limapangidwa ndi anode, cathode, separator, electrolyte, ndi awiri osonkhanitsa (zabwino ndi zoipa). Anode ndi cathode amasunga lithiamu. Ma electrolyte amanyamula ma lithiamu ayoni kuchokera ku anode kupita ku cathode komanso mosemphanitsa ndi kupatula. Kuyenda kwa ma lithiamu ayoni kumapangitsa ma elekitironi aulere mu anode omwe amalipiritsa kwa omwe akutenga pakadali pano. , kompyuta, ndi zina zambiri) kwa osonkhanitsa pakadali pano. Wopatukanawo amatseka ma elekitironi mkati mwa batri. "

Nchifukwa chiyani moto wonse?
Mabatire a Lithium Ion amakhala ndi Thermal Runaway. Izi zimachitika pamene olekanitsa akuletsa kutuluka kwa ma elekitironi mu batri kukanika.

Zotsatira pa Makampani Otumiza

Lithium Ion Battery Fires A Threat to Container Shipping1

Pamoto wowopsa pa 4 Januware 2020 COSCO Pacific idawotchedwa ndi chidebe chikuyenda kuchokera ku Nansha, China ku Nhava Shevaby, India .. Moto, ngakhale udazimitsidwa ndipo palibe ovulala akuti za kuwonongeka kunafufuzidwa.

MY Kanga, padoko la Dubrovnik, Croatia adasowa kwathunthu pomwe chombo chidakumana ndi moto wowopsa. Moto uwu udachitika chifukwa chothamangitsa kutenthedwa kwa ma batri angapo a LI-pa zotengera zosangalatsa zomwe zimakhala mu garaja ya yacht. Pamene mphamvu yamoto idakulirakulira, ogwira ntchito ndi omwe adakwera adakakamizidwa kusiya chombo.

Monga owerenga amadziwa, panyanja pali magulu asanu amoto osiyanasiyana. A, B, C, D, ndi K. Lithium Ion mabatire makamaka ndi moto wa Class D. Kuopsa kwakuti sangathe kuzimitsidwa ndi madzi kapena kupsereza ndi CO2. Moto wa m'kalasi D umawotcha mokwanira kuti apange Oxygen yawoyawo. Izi zikutanthauza kuti amafunikira njira yapadera yozimitsira

Mpaka posachedwa panali njira ziwiri zokha zothetsera moto wa lithiamu. Wozimitsa moto amatha kulola kuti zida zamagetsi ziwotche mpaka mafuta onse atatha, kapena kuzimitsa chowotacho ndi madzi ambiri. Zonsezi "zothetsera" zili ndi zovuta zina. Kuwonongeka kwa moto kumadera oyandikira kutha kukhala kwakukulu kupangitsa kuti njira yoyamba isavomerezedwe. Kuphatikiza apo, moto m'ngalawa, ndege kapena malo ena otsekedwa ukhoza kukhala wowopsa. Kuzimitsa moto ndikofunikira.

Kuwotcha moto ndi madzi ambiri kumachepetsa kutentha kwa omenyera pansi pa poyatsira (180C / 350F), komabe, wozimitsa moto ali pafupi ndi batri loyaka ndipo madzi owonjezerawo atha kuwononga zida ndi ziwiya mosayembekezereka.

Kukonzekera kwaposachedwa kumapereka njira yatsopano, yothandiza kwambiri. Kufunika kochepetsa kutentha kwa batri pothawa, kutulutsa mpweya (utsi, womwe ndi poizoni) mwachangu tsopano ukupezeka. Kutukuka kwaukadaulo kumachitika pogwiritsa ntchito mikanda yamagalasi yobwezerezedwanso yomwe idapangidwa kuti izitha kutentha ndi nthunzi. Kuyesa kukuwonetsa kuti laputopu yoyaka imazimitsidwa m'masekondi 15. Njira yogwiritsira ntchito imateteza wozimitsa moto.

Tekinoloje yatsopanoyi ndi chifukwa cha kuyesetsa kwa CellBlock kuthandiza mafakitale angapo kuthana ndi moto wa ma lithiamu. Asayansi a CellBlock adazindikira kuti moto wa ma lithiamu ubwera kudzachulukana. Magawo osiyanasiyana azachuma adzakhudzidwa kuphatikiza pakupanga, ndege, chithandizo chamankhwala ndi ena. Akatswiri opanga ma CellBlock omwe amayang'ana zovuta zoyendetsa m'makampani a moto wa lithiamu amabweretsa chidwi kwa ndege (zonyamula ndi zonyamula), ndipo tsopano ndianyanja.

Kuopsa kwa Maritime

Chuma chathu chili padziko lonse lapansi ndipo katundu amatumizidwa padziko lonse lapansi, ndipo mkati mwazinthu zambiri zotumizirazo pali mabatire a lithiamu. Bungwe lomwe limapereka kutumiza lili pachiwopsezo panthawi yomwe mabatire a lithiamu amakhala. Kukhala ndi mphamvu yozimitsa batire yomwe imalowera kuthawa mwachangu, zisanawonongeke kwambiri.

Ndege ziwiri zataya 747 chifukwa cha moto wa batriyamu ya lithiamu. Aliyense anali ndi mabatire opitilira 50,000 pabwalo ndipo zoyatsira zimayikidwa m'makontenawo. Zombo zimanyamula mabatire mamiliyoni ambiri. Kukhala ndi luso lotha kuzimitsa batire ya lithiamu mwachangu kumatha kusiyanitsa zochitika ndi tsoka.
