Batirin kwalta sun yi kyau, amma siminti / siminti-ion ya fi kyau. Gina a matsayin kantin makamashi
Sama da shekaru biyu da suka gabata, mun bayyana yadda kwalta ta halitta zata iya ƙara ƙarfin baturin lithium-ion. Yanzu akwai buƙatar wasu kayan da muke ci karo da su kowace rana. Masu bincike a Jami'ar Fasaha ta Chalmers da ke Sweden suna kallon manufar tubalan a matsayin babban baturi. Kuma sun riga sun sami samfurin siminti-ion baturi.

Tunanin yana da sauƙi: bari mu juya abubuwan da ke kewaye da mu zuwa batura don adana makamashi a cikinsu lokacin da muke da yawa. Wannan ya fi sauƙin faɗi fiye da aikatawa. Saboda haka, masana kimiyya a Jami'ar Chalmers sun yanke shawarar haɓakawa Kwayoyin tushen siminti. Anode Anyi da Nickel Plated Carbon Fiber Mesh. Cathode raga iri ɗaya ne, amma an lulluɓe shi da ƙarfe. Dukansu gratings an cusa su a cikin wani cakuda tushen siminti mai sarrafa wutar lantarki wanda aka haɗa tare da ƙarin gajerun zaruruwan carbon.
Tantanin halitta samfurin yana nan kuma yana aiki a cikin dakin gwaje-gwaje.a cikin hoton farko, yana kunna diode (source). Yawan makamashi bai wuce kima ba kamar yadda yake 0,0008 kWh / l (0,8 Wh / l) ko 0,007 kWh / mXNUMX.2... Don kwatanta: Kwayoyin lithium-ion na zamani suna ba da awoyi ɗari da yawa a kowace lita (Wh / l), wanda ya ninka sau ɗari.. Amma wannan karamar matsala ce, ganin cewa tubalan siminti (concrete) gine-gine ne na ɗaruruwan cubic mita.
Batirin siminti, wanda masana kimiyya a jami'ar Chalmers suka kirkira, ya ninka na'urori makamantan na baya sau goma. Mafi mahimmanci, ana iya caje shi kuma a sake shi sau da yawa. Masu bincike suna taka tsantsan: yayin da yake game da diodes mai ƙarfi, ƙananan na'urori masu auna firikwensin ko tsarin kula da zirga-zirgar ababen hawa a kan hanyoyi da gadoji.
