A wasu lokuta ana kiran haɗin gine-gine “marasa yawa”, amma bai kamata a ɗauki wannan kalmar a zahiri ta ma'anar da ke da siffa ta ilimin kimiyyar farko ba. Kwayoyin "Massless" a cikin mota kawai sel ne waɗanda ba su da ƙarin ballast saboda suna aiki a matsayin kwarangwal, ƙarfafawa, da dai sauransu - mahimman tsari a cikin mota.

Jami’ar Chalmers da KTH ne suka kirkire su, kwayoyin sun kunshi na’urorin lantarki guda biyu: carbon fiber (anode) da lithium iron phosphate (cathode), a tsakanin su akwai fiber na gilashi mai cike da electrolyte. Idan muka dubi rikodin, za mu iya cewa duk waɗannan ana tattara su a cikin jiki guda ɗaya:

Wannan shine yadda ake ƙirƙirar hanyar haɗin gwiwa na roba kuma ina kan wayoyin ƙarfin lantarki 8,4 volts (3 x 2,8V). Masana kimiyya sun yarda sun ci nasara yawan makamashi сейчас 0,024 kWh / kg, wanda ya fi sau goma ƙasa da mafi kyawun batura na zamani (0,25-0,3 kWh / kg). Duk da haka, idan muka tuna cewa tare da na gargajiya abubuwa wajibi ne don ƙara nauyi na kayayyaki da baturi hali, da bambanci ya zama "kawai" sau 6-8.

Junior moduleda modules na elasticity na tsarin mahada na samfur ne fiye da 28 GPA... Don kwatantawa: filastik, wanda aka ƙarfafa da fiber carbon, yana da ma'aunin Matasa na 30-50 GPa, don haka tantanin halitta na Jami'ar Chalmers da KTH ba ya bambanta da yawa da takwaransa na gargajiya.

Masana kimiyya suna so Rage girman mai rarrabawa a mataki na gaba kuma maye gurbin foil na aluminum akan lantarki tare da kayan fiber carbon. An ɗauka cewa, godiya ga waɗannan haɓakawa, za su kai matakin 0,075 kWh / kg da 75 GPa.... Kuma ko da irin waɗannan nau'ikan ƙwayoyin cuta suna da tsada don amfani da su a cikin motoci, suna iya aiki da kyau, misali, a cikin jirgin sama.
