Mevcut tamamen kat\u0131 hal lityum bataryalar (ASLB), iletimi art\u0131rmak i\u00e7in elektrokimyasal olarak aktif olmayan katk\u0131 maddeleri gerektiren heterojen kompozit katotlar <\/strong>nedeniyle zorluklarla <\/strong>kar\u015f\u0131la\u015f\u0131yor.

Ekip, \u00e7al\u0131\u015fmalar\u0131nda pillerinin gram ba\u015f\u0131na 250 mAh<\/strong>‘lik \u00f6zg\u00fcl bir kapasiteye sahip oldu\u011funu buldu. Standart lityum iyon bataryalarda bu, gram ba\u015f\u0131na 100-200 mAh seviyesinde yer al\u0131yor. Ayr\u0131ca ara\u015ft\u0131rmac\u0131lar, yeni ASLB\u2019nin 20.000 d\u00f6ng\u00fcden fazla istikrarl\u0131 \u00e7al\u0131\u015fma<\/strong> ve h\u00fccre d\u00fczeyinde 390 Wh enerji yo\u011funlu\u011fu<\/strong> sundu\u011funu s\u00f6yl\u00fcyor.

T\u00fcm bunlar\u0131n oda s\u0131cakl\u0131\u011f\u0131nda oldu\u011funu da belirtelim.<\/p>\n

Y\u00fcksek enerji yo\u011funlu\u011fu ve uzun kullan\u0131m \u00f6mr\u00fc sayesinde tam kat\u0131 hal lityum bataryalar enerji depolamada b\u00fcy\u00fck potansiyele sahip olabilir.

Enerji depolaman\u0131n \u00f6tesinde bu tipteki bataryalar elektrikli ara\u00e7larda da kullan\u0131l\u0131yor. \u015eimdilik yayg\u0131n bir seri \u00fcretim olmasa da kat\u0131 hal bataryalar 2025-2027 aras\u0131nda kapsaml\u0131 \u00fcretimlere \u00e7e\u015fitli firmalar arac\u0131l\u0131\u011f\u0131yla girecek.<\/p>\n\n
