An shigar da sababbin batura a tashar sararin samaniya ta duniya: Li-ion, 357 kWh. Tsohon NiMH ya nufi Duniya
Fakitin baturi mai nauyin ton 2,9 nickel karfe hydride an tarwatsa kuma an sake shi daga tashar sararin samaniya ta kasa da kasa (ISS). Ana sa ran za su kewaya duniya na tsawon shekaru biyu zuwa hudu sannan su kone a sararin samaniya. An maye gurbin na'urori 48 tare da ƙwayoyin hydride na nickel-metal tare da nau'ikan 24 tare da ƙwayoyin lithium-ion.
ISS baturi: LiCoO2, 357 kWh, har zuwa 60 hawan keke
An yi amfani da batir NiMH akan ISS don adana makamashin da sel na hotovoltaic ke samarwa. Mafi tsufa yana aiki tun 2006, don haka NASA ta yanke shawarar maye gurbin ta lokacin da ta kai ga rayuwarta mai amfani. An yanke shawarar cewa sabbin batura za su dogara ne akan ƙwayoyin lithium-ion, waɗanda ke ba da mafi girman ƙarfin kuzari a kowace raka'a na taro da girma.
An dauka cewa sababbin abubuwa dole ne su yi tsayayya da shekaru 10 da 60 aiki hawan kekekuma a ƙarshen rayuwa yana ba da mafi ƙarancin 48 Ah maimakon ainihin 134 Ah (0,5 kWh). Kamar yadda kuke gani, NASA ta yarda da mafi ƙasƙanci fiye da masu yin EV saboda kawai kashi 36 na ƙarfin asali ana ɗaukar ƙarshen rayuwa. A cikin motocin lantarki, ana saita madaidaicin kofa a kusan kashi 65-70 na ƙarfin baturin masana'anta.
A cikin sake zagayowar gwaji, an yanke shawarar cewa za a gina batura (mafi daidai: Modules ORU) akan tushen sel. GS Yusa tare da cathodes da aka yi da lithium-cobalt oxide (LiCoO2). Kowannen su ya ƙunshi irin waɗannan sel guda 30, don haka ɗayan ɗayan yana da ikon 14,87 kWh. Cikakken saitin batura don adana har zuwa 357 kWh na makamashi... Kamar LiCoO Kwayoyin2 na iya fashewa idan an lalace, an gudanar da gwaje-gwaje da dama, ciki har da halayensu lokacin huda da caji.
Aikin maye gurbin baturi ya fara ne a cikin 2016 kuma ya ƙare a ranar Alhamis 11 ga Maris. An harba wani pallet mai batura 48 na NiMH zuwa Duniya - a cikin hoton ana iya ganin su a nisan kilomita 427 sama da Chile.... Bayan an sake shi, ya motsa da sauri na 7,7 km / s a cikin kewayawa a hankali a hankali. NASA ta kiyasta cewa a cikin shekaru biyu zuwa hudu kayan za su shiga sararin samaniya kuma su kone a cikinsa "Ba tare da wani lahani ba." Idan akai la'akari da nauyin kit (ton 2,9) da tsarinsa (modules masu haɗin kai), ya kamata mu yi tsammanin mota mai haske wanda ke rushewa cikin ruwan sama na tarkace.
Da fatan, saboda 2,9 ton shine nauyin babban SUV da gaske. Kuma "sharar" mafi nauyi da aka fitar daga tashar sararin samaniya ta kasa da kasa ...
