Amabhethri e-lithium-ion anezinsuku zawo ezibaliwe! Ingabe i-graphene iyakhala?

Imithombo evela embonini yezimoto imemezela ukufika kobuchwepheshe obusha lokho kuzothatha indawo yamabhethri i-lithium-ion isivele isetshenziswe kwamanye amamodeli. Lobu buchwepheshe obusha buthembisa thuthukisa ukusebenza kokubili ekuzilawuleni nasekuthembekeni.

Okwamanje, azikho izinsuku eziqondile zokufika kwakhe; Akwaziwa nokuthi zizobiza malini nokuthi zingafakwa kuziphi izinhlobo zezimoto. Nokho, kuyaziwa mayelana yiziphi izinhlobo zobuchwepheshe eziklanywayo futhi yiziphi izinzuzo abangazithola; okuyinto engabaza labo abasebenzayo njengamanje.

Amamodeli ayiHybrid ekuqaleni asebenzisa amabhethri ukwakheka kwawo kwakusekelwe i-lead acid (Pb) ne-Nickel-Cadmium (NiCd). Izizukulwane zakamuva zamamotho kagesi zisebenzisa amabhethri ahlanganiswe, i-lithium-ion, ithuthukisa kakhulu ezandulele. Kangangokuthi akekho umenzi onesibindi sokusebenzisa obunye ubuchwepheshe.

Nokho, konke lokhu kubonakala kushintsha, futhi maduze nje. Sisanda kukwazisa ukuthi abazalwa kabusha UFisker ufuna ukufaka imodeli yakhe elandelayo, i-eMotion, amabhethri ane i-graphene polymer (sibonga isivumelwano esifinyelelwe phakathi kwakhe ne-Energy Inc). Le nto kagesi eyi-superconducting, eyenziwe ngama-athomu ekhabhoni emsulwa, iyakwazi ukwakha ukuzimela emotweni kagesi enkulu kune 800 amakhilomitha.

Izinzuzo ze i-graphene ziningi futhi zibalulekile ngempela. I isikhathi sokushaja singaba yimizuzu emi-5, ngenkathi indawo ehlala abantu iyancipha phakathi kuka-20 no-30%. Izici zayo ezingokomzimba ziyamangaza: obala, high thermal kanye conductivity kagesi. Kuyakhanya futhi futhi ekwazi ukuzikhiqizela ugesi ngokwawo ukufinyelelwa yizinhlayiya ezenza ukukhanya.

Mayelana nokuqina, impilo yayo ewusizo iphakeme izikhathi ezi-4 kuleyo yebhethri ye-lithium-ion futhi, njengokungathi lokho akwanele, umthwalo ungaba inductive.

Nakuba sesivele sikufundile, ikusasa elihle amabhethri azoba nalo liyaqinisekiswa. Kulesi senzakalo, i-graphene izoba umlingiswa oyinhloko. Leyo mboni eyathola i- Umklomelo weNobel kuPhysics ngo-2010, imvulela ikusasa elihle eminyakeni ezayo embonini yezimoto.
