A vizsg\u00e1latok sor\u00e1n a Donut Solid-State Battery V1-nek nevezett cell\u00e1val dolgoztak a szakemberek, amelynek n\u00e9vleges kapacit\u00e1sa 26 Ah, n\u00e9vleges energi\u00e1ja pedig 94 Wh 3,6 V fesz\u00fclts\u00e9gen. Els\u0151 l\u00e9p\u00e9sk\u00e9nt a cell\u00e1t szobah\u0151m\u00e9rs\u00e9kleten (+20\u00b0C) t\u00f6lt\u00f6tt\u00e9k fel, majd 24 amperes \u00e1rammal kis\u00fct\u00f6tt\u00e9k, ami 24,9 Ah kapacit\u00e1st eredm\u00e9nyezett. Ez nagyj\u00e1b\u00f3l 4%-kal marad el a gy\u00e1rt\u00f3 \u00e1ltal megadott n\u00e9vleges kapacit\u00e1st\u00f3l, \u00e9s alapk\u00e9nt szolg\u00e1lt a magas h\u0151m\u00e9rs\u00e9klet\u0171 tesztekhez.<\/p>\n

Ezut\u00e1n a cell\u00e1t 80\u00b0C-ra meleg\u00edtett\u00e9k, \u00e9s ism\u00e9t 24 amperes \u00e1rammal kis\u00fct\u00f6tt\u00e9k. A cella 27,5 Ah kapacit\u00e1st mutatott, ami a szobah\u0151m\u00e9rs\u00e9kleti teljes\u00edtm\u00e9ny 110,5%-a. Ez sokak sz\u00e1m\u00e1ra meglep\u0151nek t\u0171nhet, \u00e1m a kutat\u00f3k szerint ez a jelens\u00e9g \u00f6sszhangban van a szil\u00e1rdtest-elektrolit viselked\u00e9s\u00e9vel: az ionok vezet\u0151k\u00e9pess\u00e9ge a h\u0151 hat\u00e1s\u00e1ra javul, \u00edgy a teljes\u00edtm\u00e9ny n\u0151, \u00e9s mivel a cella nem tartalmaz gy\u00fal\u00e9kony foly\u00e9kony elektrolitot, a t\u0171zvesz\u00e9ly \u00e9s k\u00e1rosod\u00e1s kock\u00e1zata jelent\u0151sen cs\u00f6kken.<\/p>\n

A vizsg\u00e1lat k\u00f6vetkez\u0151 l\u00e9p\u00e9sek\u00e9nt a cell\u00e1t 100\u00b0C-ra meleg\u00edtett\u00e9k, \u00e9s 12 amperes \u00e1rammal s\u00fct\u00f6tt\u00e9k ki. A kapacit\u00e1s ekkor 27,6 Ah lett, azaz a szobah\u0151m\u00e9rs\u00e9kleti referencia 107,1%-\u00e1t \u00e9rte el.<\/p>\n

Minden esetben a teszt ut\u00e1n a cella norm\u00e1lisan \u00fajrat\u00f6lthet\u0151 volt. Ez rendk\u00edv\u00fcl szokatlan, hiszen a hagyom\u00e1nyos l\u00edtiumionos zacsk\u00f3s cell\u00e1kn\u00e1l m\u00e1r 60-70\u00b0C felett jelent\u0151sen megn\u0151 a k\u00e1rosod\u00e1s \u00e9s a h\u0151elszabadul\u00e1s vesz\u00e9lye. A Donut Lab cell\u00e1ja ezzel szemben nemcsak t\u00fal\u00e9lte az extr\u00e9m h\u0151m\u00e9rs\u00e9kletet, hanem kapacit\u00e1sa m\u00e9g n\u00f6vekedett is.<\/p>\n

Fontos megfigyel\u00e9s azonban, hogy a 100\u00b0C-os kis\u00fct\u00e9s ut\u00e1n a cella k\u00fcls\u0151 tasakja elvesztette a v\u00e1kuum\u00e1t. Egyszer\u0171en fogalmazva, a l\u00e9gmentes burkolatba leveg\u0151 ker\u00fclt, ami norm\u00e1l k\u00f6r\u00fclm\u00e9nyek k\u00f6z\u00f6tt a csomagol\u00e1s s\u00e9r\u00fcl\u00e9s\u00e9nek sz\u00e1m\u00edtana. A VTT jelent\u00e9se szerint azonban a bels\u0151 akt\u00edv anyagok teljesen m\u0171k\u00f6d\u0151k\u00e9pesek maradtak, \u00e9s a cella a teszt ut\u00e1n probl\u00e9ma n\u00e9lk\u00fcl \u00fajrat\u00f6lthet\u0151 volt. A Donut Lab ezt a jelens\u00e9get a cella h\u0151\u00e1ll\u00f3s\u00e1g\u00e1nak bizony\u00edt\u00e9kak\u00e9nt \u00e9rt\u00e9keli.<\/p>\n

A c\u00e9g szerint a tesztek meger\u0151s\u00edtik, hogy a cella nemcsak j\u00f3l b\u00edrja a h\u0151sokkot, de extr\u00e9m h\u0151m\u00e9rs\u00e9kleten is k\u00e9pes biztons\u00e1gosan, stabilan m\u0171k\u00f6dni. Ville Piippo, a Donut Lab m\u0171szaki vezet\u0151je kiemelte, hogy a cella teljes kapacit\u00e1sa 80\u00b0C \u00e9s 100\u00b0C-on is kihaszn\u00e1lhat\u00f3 volt, mik\u00f6zben a cella nem melegedett t\u00fal, \u00e9s t\u00f6lt\u00e9s ut\u00e1n hib\u00e1tlanul m\u0171k\u00f6d\u00f6tt, ami mind a teljes\u00edtm\u00e9nyre, mind a biztons\u00e1gra vonatkoz\u00f3an \u00edg\u00e9retes eredm\u00e9ny.<\/p>\n

Ugyanakkor a szakmai k\u00f6z\u00f6ss\u00e9g tov\u00e1bbra is kritikus. A VTT tesztek ugyan f\u00fcggetlen\u00fcl m\u00e9rtek teljes\u00edtm\u00e9nyt \u00e9s kapacit\u00e1st, de nem er\u0151s\u00edtett\u00e9k meg, hogy a cella val\u00f3ban l\u00edtium n\u00e9lk\u00fcli szil\u00e1rdtest-akkumul\u00e1tor lenne, r\u00e1ad\u00e1sul t\u00f6bben is, k\u00f6zt\u00fck egyetemi kutat\u00f3k felvetett\u00e9k, hogy a t\u00f6lt\u00e9si g\u00f6rbe \u00e9s egy\u00e9b adatok alapj\u00e1n k\u00f6nnyen lehet, hogy val\u00f3j\u00e1ban l\u00edtiumion-cell\u00e1r\u00f3l van sz\u00f3. A cella csomagol\u00e1s\u00e1nak elvesztett v\u00e1kuuma tov\u00e1bbi k\u00e9rd\u00e9seket vet fel a hossz\u00fa t\u00e1v\u00fa tart\u00f3ss\u00e1gr\u00f3l \u00e9s a gy\u00e1rt\u00e1si min\u0151s\u00e9gr\u0151l.<\/p>\n
