S\u0131k\u00e7a Sorulan Sorular<\/h2>\n\n\n\n

Lityum pil ay\u0131r\u0131c\u0131 kaplamas\u0131nda standart al\u00fcmina yerine neden b\u00f6hmit tercih edilir?<\/h3>\n\n\n\n

\u0130ki malzeme sertlik, yo\u011funluk ve termal davran\u0131\u015f a\u00e7\u0131s\u0131ndan farkl\u0131l\u0131k g\u00f6sterir; bunlar\u0131n hepsi kaplama i\u015flemini ve pilin g\u00fcvenlik performans\u0131n\u0131 etkiler. Boehmit (Mohs 3-4), standart al\u00fcminadan (Mohs 9) \u00f6nemli \u00f6l\u00e7\u00fcde daha yumu\u015fakt\u0131r; bu da ay\u0131r\u0131c\u0131 \u00fcretim hatt\u0131ndaki kaplama silindirlerinde, kesme b\u0131\u00e7aklar\u0131nda ve da\u011f\u0131t\u0131m ekipmanlar\u0131nda \u00f6nemli \u00f6l\u00e7\u00fcde daha az a\u015f\u0131nmaya neden oldu\u011fu anlam\u0131na gelir. Boehmitin daha d\u00fc\u015f\u00fck yo\u011funlu\u011fu (al\u00fcmina i\u00e7in 3,9 g\/cm\u00b3'e kar\u015f\u0131l\u0131k yakla\u015f\u0131k 3,0 g\/cm\u00b3), e\u015fde\u011fer koruyucu performans i\u00e7in daha ince ve daha hafif bir kaplama tabakas\u0131 anlam\u0131na gelir. En \u00f6nemli fonksiyonel fark termaldir: boehmit, 300 santigrat derecenin \u00fczerinde endotermik dehidrasyona u\u011frar (AlO(OH) yap\u0131sal suyunu buhar olarak salar), bu da termal ka\u00e7\u0131\u015f olay\u0131nda aktif olarak \u0131s\u0131y\u0131 emer. Standart al\u00fcmina termal olarak kararl\u0131d\u0131r ve bu aktif \u0131s\u0131 emme mekanizmas\u0131n\u0131 sa\u011flamaz. Termal y\u00f6netimin birincil g\u00fcvenlik endi\u015fesi oldu\u011fu pil h\u00fccreleri i\u00e7in, boehmitin endotermik davran\u0131\u015f\u0131 anlaml\u0131 bir ek g\u00fcvenlik pay\u0131 sa\u011flar.<\/p>\n\n\n\n

Bu boyutta, standart oluklu kal\u0131p veya grav\u00fcr kaplama i\u015flemleriyle 2-4 mikronluk d\u00fczg\u00fcn bir kaplama tabakas\u0131 elde edilebilir.

Elektrot kenar\u0131 kaplamas\u0131 (ay\u0131r\u0131c\u0131 y\u00fczey kaplamas\u0131ndan farkl\u0131 bir uygulama) i\u00e7in D50 1-6 mikron tipiktir ve daha az kat\u0131 PSD gereksinimleri vard\u0131r. Her durumda, D97 ve kaba kuyru\u011fun (10-15 mikronun \u00fczerindeki par\u00e7ac\u0131klar) olmamas\u0131, D50 kadar \u00f6nemlidir; a\u015f\u0131r\u0131 b\u00fcy\u00fck par\u00e7ac\u0131klar, ay\u0131r\u0131c\u0131n\u0131n delinme direncini azaltan kaplama kusurlar\u0131 olu\u015fturur.<\/p>\n\n\n\n
