Mabatire atsopano amaikidwa pa International Space Station: Li-ion, 357 kWh. Old NiMH adapita ku Earth
Paketi ya batire ya nickel metal hydride ya 2,9 tonne idaphatikizidwa ndikutulutsidwa ku International Space Station (ISS). Amayembekezedwa kuti azizungulira Dziko Lapansi kwa zaka ziwiri kapena zinayi kenako n’kuwotchedwa mumlengalenga. Ma module a 48 okhala ndi nickel-metal hydride cell adasinthidwa ndi ma module a 24 okhala ndi maselo a lithiamu-ion.
Batire ya ISS: LiCoO2, 357 kWh, mpaka 60 ntchito zozungulira
Mabatire a NiMH adagwiritsidwa ntchito pa ISS kuti asunge mphamvu zomwe zimapangidwa ndi maselo a photovoltaic. Wakale kwambiri wakhala akugwira ntchito kuyambira 2006, kotero NASA idaganiza kuti iyenera kusinthidwa ikafika pa moyo wake wothandiza. Anaganiza kuti mabatire atsopano adzakhala zochokera lithiamu-ion maselo, amene amapereka apamwamba mphamvu kachulukidwe pa unit ya misa ndi voliyumu.
Zinkaganiziridwa kuti zinthu zatsopano ziyenera kupirira zaka 10 ndi 60 ntchito zozungulirandipo kumapeto kwa moyo perekani osachepera 48 Ah m'malo mwa 134 Ah (0,5 kWh). Monga mukuwonera, NASA ikugwirizana ndi kunyozeka kochulukirapo kuposa opanga ma EV chifukwa 36 peresenti yokha ya mphamvu zoyambira imatengedwa ngati kutha kwa moyo. M'magalimoto amagetsi, malo olowera m'malo nthawi zambiri amakhala pafupifupi 65-70 peresenti ya mphamvu ya batri ya fakitale.
Mumayendedwe oyesera, adaganiza kuti mabatire (momwemo: ma module a ORU) adzamangidwa pamaziko a ma cell. Professor Yuasa ndi ma cathodes opangidwa ndi lithiamu-cobalt oxide (LiCoO2). Iliyonse imakhala ndi ma cell 30, motero gawo limodzi lili ndi mphamvu ya 14,87 kWh, mabatire athunthu osungira mphamvu mpaka 357 kWh... Monga ma cell a LiCoO2 akhoza kuphulika ngati awonongeka, mayesero angapo achitika, kuphatikizapo khalidwe lawo poboola ndi kubwezeretsanso.
Ntchito yosinthira batire idayamba mu 2016 ndipo idatha Lachinayi 11 Marichi. Pallet yokhala ndi mabatire a 48 NiMH idayambika kupita ku Dziko Lapansi - pachithunzichi ikuwoneka pamtunda wa makilomita 427 kumtunda kwa Chile.... Ikatulutsidwa, idayenda pa liwiro la 7,7 km / s munjira yocheperako pang'onopang'ono. NASA ikuyerekeza kuti m'zaka ziwiri kapena zinayi katunduyo adzalowa mumlengalenga ndi kutentha m’menemo "Popanda vuto lililonse." Poganizira kulemera kwa zida (matani 2,9) ndi kapangidwe kake (ma module olumikizana), tiyenera kuyembekezera galimoto yowala yomwe imagwa mvula yazinyalala.
Tikukhulupirira, chifukwa matani 2,9 ndi kulemera kwa SUV lalikulu kwenikweni. Ndipo "zinyalala" zolemera kwambiri zotayidwa ku International Space Station ...
