Abstract

Hidrojen depolama alaşımları şarj edilebilir Ni-MH
pillerinin pratik uygulamaları için son zamanların çok geniş araştırma konusunu
oluşturmaktadır. Bu derleme çalışmasında şarj edilebilir Ni-MH pilleri için
AB5-tip, AB2-tip, TiV esaslı, R-Mg-Ni esaslı ve Mg-Ni esaslı hidrojen depolama
alaşımlarının son yıllardaki gelişmeleri detaylı olarak anlatılmıştır. Son
yıllarda gerçekleşen gelişmelere bağlı olarak var olan problemler ve ilgili sonuçlar
sistematik olarak değerlendirilmiştir. Hidrojen depolama alaşımlarının, alaşım
kompozisyonları, kristal yapıları ve elektrokimyasal özellikleri arasındaki
bağlantı her bir alaşım çeşidi için tanımlanmış ve güç pilleri üzerinden analiz
edilmiştir. Gelişen elektrikli araçlarda kullanımları için Ni-MH pillerindeki
zorluklar bu çalışmada tartışılmıştır.
