Aikin Turai LISA yana gab da farawa. Babban makasudin: ƙirƙirar batirin lithium-sulfur tare da yawa na 0,6 kWh / kg
Daidai a ranar 1 ga Janairu, 2019, aikin Turai na LISA ya fara, babban burin wanda zai kasance ci gaban kwayoyin Li-S (lithium-sulfur). Saboda kaddarorin sulfur, wanda ya fi ƙarfin ƙarfe da ake amfani da su a yau, ƙwayoyin sulfur na lithium na iya isa wani takamaiman makamashi na 0,6 kWh / kg. Mafi kyawun ƙwayoyin lithium-ion na zamani a yau suna kusa da 0,25 kWh / kg.
Abubuwan da ke ciki
- Kwayoyin Sulfur na Lithium: Makomar Motoci, Jirage da Kekuna
- Aikin LISA: Batir lithium-polymer masu girma da tsada kuma maras tsada tare da daskararrun electrolyte.
Masana kimiyya da ke aiki akan ƙwayoyin lantarki sun gwada ƙwayoyin lithium sulfur da yawa tsawon shekaru masu yawa. Ƙarfin su yana da kyau saboda sun yi alkawari na ban sani takamaiman makamashi 2,6 kWh / kg (!). A lokaci guda, sulfur abu ne mai arha kuma samuwa, saboda sharar gida ce daga masana'antar wutar lantarki.
Abin takaici, sulfur ma yana da illa: duk da cewa yana ba da garantin ƙarancin nauyin ƙwayoyin sel - wanda shine dalilin da ya sa aka yi amfani da ƙwayoyin Li-S a cikin jirgin sama na lantarki, suna karya bayanan jiragen sama marasa tsayawa, kaddarorin sinadarai na physico-sunadarai sun sa ya zama cikakke. narkar da sauri a cikin electrolyte... Watau: Batirin Li-S yana da ikon adana babban caji a kowace naúrar, amma yayin aiki ya lalace ba zato ba tsammani..
> Batirin Rivian yana amfani da sel 21700 - kamar Tesla Model 3, amma mai yiwuwa LG Chem.
Aikin LISA: Batir lithium-polymer masu girma da tsada kuma maras tsada tare da daskararrun electrolyte.
LISA (lithium sulfur don amintaccen wutar lantarki) ana sa ran zai šauki fiye da shekaru 3,5. An ba da haɗin kai a cikin adadin Yuro miliyan 7,9, wanda yayi daidai da kusan zloty miliyan 34. Yana halartar Oxis Energy, Renault, Varta Micro Baturi, Fraunhofer Institute da Dresden Jami'ar Fasaha.
Aikin LISA yana da nufin haɓaka ƙwayoyin Li-S tare da ƙwararrun ƙwararrun ƙwararrun ƙwararrun ƙwararrun ƙwararrun ƙwayoyin cuta. Wajibi ne a magance matsalar kariya ta lantarki, wanda ke haifar da saurin lalacewa na sel. Masana kimiyya sun ce daga ka'idar makamashi yawa na 2,6 kWh / kg, a gaskiya 0,6 kWh / kg za a iya samu.
> Kwalta (!) Zai ƙara ƙarfin aiki kuma yana hanzarta cajin batir lithium-ion.
Idan da gaske yana kusa da wannan lambar, tare da nauyin kilogiram ɗari da yawa Batura na motocin lantarki zasu ragu daga dozin da yawa (!) Zuwa kusan kilo 200.... Wannan na iya zama ƙusa a cikin akwatin gawar motocin hydrogen cell (FCEVs), kamar yadda tankunan hydrogen na Toyota Mirai kaɗai ke da nauyin kusan kilogiram 90.
Za a bunkasa aikin a karkashin kulawar Oxis Energy (source). Kamfanin ya ce ya riga ya yi nasarar ƙirƙirar sel masu ƙarfin ƙarfin 0,425 kWh / kg waɗanda za a iya amfani da su a cikin jirgin sama. Koyaya, ba a san tsawon rayuwarsu da juriyar hawan caji ba.
> Batirin Li-S - juyin juya hali a cikin jirgin sama, babura da motoci
Wannan na iya sha'awar ku:
