Mwachidule
Ndi ngozi yowonjezereka chifukwa cha batri ya lithiamu-ion ikuchitika, Anthu amakhudzidwa kwambiri ndi kuthawa kwa batri, monga kuthawa kwa matenthedwe komwe kumachitika mu selo limodzi kumatha kufalitsa kutentha kumaselo ena, zomwe zimapangitsa kuti atseke dongosolo lonse la batri.
Mwachizoloŵezi, timayambitsa kutha kwa matenthedwe potenthetsa, kupachika kapena kulipiritsa panthawi yoyesera. Komabe, njirazi sizingathe kuwongolera kutha kwa matenthedwe mu cell yomwe yatchulidwa, komanso sizingagwiritsidwe ntchito poyesa makina a batri. Posachedwapa anthu akupanga njira yatsopano yoyambitsa kuthawa kwa kutentha. Mayeso a Propagation mu IEC 62619: 2022 yatsopano ndi chitsanzo, ndipo akuti njira iyi idzagwiritsidwa ntchito kwambiri mtsogolo. Nkhaniyi ndi yofotokoza njira zatsopano zomwe zikufufuzidwa.
Kutulutsa kwa laser:
Laser cheza ndi kutentha malo ang'onoang'ono ndi mkulu mphamvu laser zimachitika. Kutentha kumayendetsedwa mkati mwazinthu. Laser poizoniyu chimagwiritsidwa ntchito m'madera processing zinthu, monga kuwotcherera, kulumikiza ndi kudula. Nthawi zambiri pali mitundu ya laser motere:
- CO2laser: carbon dioxide molecular gasi laser
- Semiconductor laser: Diode laser yopangidwa ndi GaAs kapena CdS
- LAG laser: Sodium laser yopangidwa ndi yttrium aluminium garnet
- Ulusi wa kuwala: laser yopangidwa ndi galasi lopangidwa ndi galasi losowa kwambiri padziko lapansi
Ofufuza ena amagwiritsa ntchito laser ya 40W, 1000nm wave kutalika ndi 1mm m'mimba mwake kuyesa pama cell osiyanasiyana.
Zinthu zoyesa | Zotsatira za mayeso |
3 Ah Pouch | Kuthamanga kwamafuta kumachitika pambuyo pa mphindi 4.5 kuwombera laser. Choyamba 200mV dontho, ndiye voteji kutsika mpaka 0, panthawiyi kutentha kuthamanga mpaka 300 ℃. |
2.6Ah LCO Cylinder | Sizingayambitse. Kutentha kumangofika ku 50 ℃. Amafuna kuwombera mwamphamvu kwambiri laser. |
3Ah NCA Cylinder | Kuthamanga kwamafuta kumachitika pakatha mphindi 1. Kutentha kumakwera mpaka 700 ℃ |
Kukhala ndi CT scan pa cell yomwe sinayambike, zitha kupezeka kuti palibe chikoka chokhazikika kupatula dzenje lomwe lili pamwamba. Zimatanthawuza kuti laser ndi yolunjika, komanso yamphamvu kwambiri, ndipo malo otentha ndi olondola. Chifukwa chake laser ndi njira yabwino yoyesera. Titha kuwongolera kusinthasintha, ndikuwerengera mphamvu zolowera ndi zotulutsa molondola. Pakadali pano laser ili ndi zabwino zake zotenthetsera ndi kupindika, monga kutentha mwachangu, komanso kuwongolera. Laser ili ndi zabwino zambiri monga:
• Ikhoza kuyambitsa kutha kwa matenthedwe ndipo sikutenthetsa ma cell oyandikana nawo. Izi ndizabwino pakukhudzana ndi kutentha
• Ikhoza kuyambitsa kusowa kwa mkati
• Ikhoza kulowetsa mphamvu zochepa ndi kutentha mu nthawi yaifupi kuti iyambitse kuthawa kwa kutentha, zomwe zimapangitsa kuti mayeserowo aziwongolera.
Thermite Reaction:
Thermite reaction ndi kupanga Aluminiyamu kuti achite ndi zitsulo okusayidi kutentha kwambiri, ndi zotayidwa kusamutsa mu aluminium okusayidi. Popeza enthalpy yopangidwa ndi aluminium oxide ndiyotsika kwambiri (-1645kJ/mol), motero imatulutsa kutentha kwambiri. Zida za Thermite zilipo, ndipo mawonekedwe osiyanasiyana amatha kutulutsa kutentha kosiyanasiyana. Chifukwa chake ofufuza amayamba kuyesa ndi thumba la 10Ah lokhala ndi thermite.
Thermite imatha kuyambitsa kuthawa kwamafuta mosavuta, koma kulowetsedwa kwamafuta ndikosavuta kuwongolera. Ochita kafukufuku akufuna kupanga makina otenthetsera omwe amakhala otsekedwa komanso otha kuyika kutentha.
Nyali ya Quartz Yamphamvu Kwambiri:
Lingaliro: Ikani nyali ya quartz yamphamvu kwambiri pansi pa selo, ndikulekanitsa selo ndi nyali ndi mbale. Mbaleyo iyenera kubowoledwa ndi dzenje, kuti zitsimikizire khalidwe la mphamvu.
Mayesowa akuwonetsa kuti amafunikira mphamvu yayikulu kwambiri komanso nthawi yayitali kuti ayambitse kuthawa kwamafuta, ndipo matenthedwe amakhala osafanana. Chifukwa chikhoza kukhala kuti kuwala kwa quartz si kuwala kolowera, ndipo kutentha kwambiri kumapangitsa kuti kusakhale koyambitsa kuthawa kwenikweni. Pakadali pano zolowetsa mphamvu sizolondola. Njira yabwino yothamangitsira kutentha ndikuwongolera mphamvu yoyambitsira ndikuchepetsa mtengo wowonjezera wowonjezera, kuti muchepetse chikoka pa zotsatira zoyesa. Chifukwa chake titha kunena kuti nyali ya quartz sizothandiza pakadali pano.
Pomaliza:
Poyerekeza ndi njira yachikale yoyambitsa kuthawa kwa matenthedwe a cell (monga kutentha, kuchulukitsitsa ndi kulowa), kufalitsa kwa laser ndi njira yothandiza kwambiri, yokhala ndi malo otenthetsera ang'onoang'ono, mphamvu yolowera yotsika komanso nthawi yayitali yoyambitsa. Izi zimathandizidwa kuti zikhale zowonjezera mphamvu zowonjezera mphamvu pa malo ochepa. Njirayi idayambitsidwa ndi IEC. Titha kuyembekezera kuti mayiko ambiri adzaganizira njira imeneyi. Komabe zimakweza kufunikira kwakukulu pazida za laser. Pamafunika magwero oyenera a laser ndi zida zotsimikizira ma radiation. Pakalipano palibe milandu yokwanira yoyesa kuthawa kwa kutentha, njira iyi ikufunikabe kutsimikizira.
