T\u00edmto procesem se zvy\u0161uje elektrick\u00fd potenci\u00e1l, a t\u00edm p\u00e1dem i elektrick\u00e1 energie obsa\u017eena v dan\u00e9 baterii.

Jejich hlavn\u00edm p\u0159\u00ednosem je jejich hmotnost, kapacita a rychlost dob\u00edjen\u00ed. Jsou vyrobeny z grafenu, supertenk\u00e9 formy uhl\u00edku, jeho\u017e hmotnost je a\u017e o 30% leh\u010d\u00ed, ne\u017e jin\u00e9 materi\u00e1ly vyu\u017e\u00edvan\u00e9 pro v\u00fdrobu bateri\u00ed.

Pokud se zam\u011b\u0159\u00edme na rychlost dob\u00edjen\u00ed, zjist\u00edme, \u017ee se zvl\u00e1dnou dob\u00edt za zlomek \u010dasu, kter\u00fd k tomu pot\u0159ebuj\u00ed baterie norm\u00e1ln\u00ed. Pokud bychom tedy nab\u00edjeli 2 baterie, jednu grafenovou a druhou na b\u00e1zi lithia, zjist\u00edme, \u017ee zat\u00edmco norm\u00e1ln\u00ed by trvalo dobit\u00ed okolo 1 hodiny, grafenov\u00e9 sta\u010d\u00ed pouze okolo 12 minut.Av\u0161ak existuje zde je\u0161t\u011b jedna nezanedbateln\u00e1 v\u00fdhoda, a to rychlost st\u00e1rnut\u00ed. Poznatky z v\u00fdvoje ukazuj\u00ed, \u017ee grafenov\u00e9 baterie st\u00e1rnou daleko pomaleji ne\u017e jak\u00fdkoliv jin\u00fd materi\u00e1l, a to p\u0159i rychl\u00e9m nab\u00edjen\u00ed.
