Awoodda dallacaadda a3D-daabacan baytariyada lithium-ion, kaas oo saddex jeer ka sarreeya kan korantada sida caadiga ah loo sameeyo.Farsamada daabacaadda 3D-ku waxay toosisaa nanoflakes graphite ee walxaha si ay u wanaajiso qulqulka ion lithium ee gudaha iyo ka soo baxa elektiroonigga (cilmi-baadhis lagu sheegay shirkii gu'ga ACS 2022).

Boqolkiiba molecules hydrocarbon ee cabbirka gaaska la oggol yahay iyada oo loo marayo axuubka polymer.Xuubku wuxuu u adkeysan karaa heerkul sare iyo xaalado adag wuxuuna bixin karaa hab tamar yar leh oo lagu kala saaro shidaalka iyo saliidda cayriin ee fudud (Sayniska2022, DOI:10.1126/sayniska.abm7686).
