A kamp\u00e1ny sor\u00e1n a start-up eddig h\u00e1rom f\u00fcggetlen, VTT \u00e1ltal v\u00e9gzett tesztsorozatot publik\u00e1lt: az els\u0151 a t\u00f6lt\u00e9s\u00a0sebess\u00e9g\u00e9t<\/a>, a m\u00e1sodik az akku magas h\u0151m\u00e9rs\u00e9kleten val\u00f3 m\u0171k\u00f6d\u00e9s\u00e9t<\/a> vizsg\u00e1lta. A napokban k\u00f6zz\u00e9tett harmadik teszt arra adott v\u00e1laszt, hogyan tartja meg t\u00f6lt\u00f6tts\u00e9g\u00e9t az akku, amennyiben napokig t\u00e9tlen\u00fcl \u00e1ll.<\/p>\n

A teszt aprop\u00f3j\u00e1t val\u00f3sz\u00edn\u0171leg az adja, hogy a Donut Lab akkumul\u00e1tor\u00e1nak szupergyors t\u00f6lthet\u0151s\u00e9ge miatt sokakban megfogalmaz\u00f3dott a szuperkondenz\u00e1tor-elm\u00e9let, miszerint a fejleszt\u00e9s val\u00f3j\u00e1ban nem egy k\u00e9miai reakci\u00f3kkal m\u0171k\u00f6d\u0151 akkumul\u00e1tor, hanem egy szuperkondenz\u00e1tor, mely az energi\u00e1t elektromos mez\u0151ben t\u00e1rolja, \u00edgy gyorsan t\u00f6lt\u0151dik, de r\u00f6vid id\u0151 alatt elvesz\u00edti a t\u00f6lt\u00e9s\u00e9t.<\/p>\n

Ennek c\u00e1fol\u00e1s\u00e1ra a Donut akkucell\u00e1t (DL-1) 50%-os t\u00f6lt\u00f6tts\u00e9gi szintre t\u00f6lt\u00f6tt\u00e9k, majd 10 napig hagyt\u00e1k t\u00e9tlen\u00fcl szobah\u0151m\u00e9rs\u00e9kleten, mik\u00f6zben a VTT minden 10. m\u00e1sodpercben m\u00e9rte a cella fesz\u00fclts\u00e9g\u00e9t. A teszt v\u00e9g\u00e9n a cella 97,7%-os kapacit\u00e1st tartott meg, azaz mind\u00f6ssze 2,3%-ot vesz\u00edtett az energi\u00e1j\u00e1b\u00f3l. A fesz\u00fclts\u00e9g 3,861\u202fV-r\u00f3l 3,733\u202fV-ra cs\u00f6kkent a 240 \u00f3ra alatt, ami a cella stabil viselked\u00e9s\u00e9t mutatja. Egy szuperkondenz\u00e1tor ezzel szemben ugyanennyi id\u0151 alatt ak\u00e1r 50%-ot is vesz\u00edtett volna a fesz\u00fclts\u00e9g\u00e9b\u0151l. A VTT meg\u00e1llap\u00edt\u00e1sai alapj\u00e1n teh\u00e1t a cella viselked\u00e9se egy\u00e9rtelm\u0171en akkumul\u00e1torra jellemz\u0151.<\/p>\n

Ez a teszt tov\u00e1bb\u00e1 v\u00e1laszt adott egy kor\u00e1bban felmer\u00fclt agg\u00e1lyra is: mivel az eddigi h\u00e1rom tesztet k\u00fcl\u00f6nb\u00f6z\u0151 cell\u00e1kon (DL1, DL2 \u00e9s DL3) v\u00e9gezt\u00e9k, felmer\u00fclt a gyan\u00fa, hogy ezek esetleg az adott tesztkrit\u00e9riumokra \u2013 gyors t\u00f6lt\u00e9s, h\u0151b\u00edr\u00e1s \u00e9s t\u00f6lt\u00e9smegtart\u00e1s \u2013 optimaliz\u00e1lt k\u00fcl\u00f6nb\u00f6z\u0151 cell\u00e1k lehetnek. A tesztek sor\u00e1n m\u00e9rt fesz\u00fclts\u00e9gprofilok hasonl\u00f3s\u00e1ga ellenben azt jelzi, hogy a cell\u00e1k l\u00e9nyeg\u00e9ben azonosak.<\/p>\n

A legfontosabb k\u00e9rd\u00e9sek, azaz a cella t\u00e9nyleges energias\u0171r\u0171s\u00e9ge \u00e9s a 100.000 ciklusos \u00e9lettartam, tov\u00e1bbra is meger\u0151s\u00edt\u00e9sre v\u00e1rnak.<\/p>\n
