Elektrochemische Speicherung und Oxidation von Wasserstoff mit der intermetallischen Verbindung LaNi5

Multi-electron reaction materials for high energy density batteries

“…In view of the battery development in the past decades, it is clear that every advance in the battery technology was brought about by the development of new materials and battery concept, such as MH-Ni batteries in the 1970s, 4 Li-ion or rocking-chair batteries at the late 1980s and early 1990s, 5,6 and polymer lithium ion (PLION) batteries. 2,7 Particularly, the appearance of novel electroactive materials based on the new concept of battery chemistry always makes a big push to improve the electrochemical performance of rechargeable batteries.…”

Rare earth–Mg–Ni-based hydrogen storage alloys as negative electrode materials for Ni/MH batteries

“…Hydrogen storage alloys are well known as a group of new functional intermetallics, which can reversibly absorb/desorb a large amount of hydrogen at or around standard temperatures and pressures [6,13,16]. A large number of hydrogen storage alloys have been developed as negative electrode materials for Ni/MH batteries, and these include AB 5 -type rare earth-based alloys [6,13,14,[15][16][17][18][19][20][21], AB 3 -or A 2 B 7 -type rare earth-magnesium-based alloys [22][23][24][25][26][27][28][29][30][31], AB 2 -type multicomponent alloys [31][32][33][34][35][36], Mg-based amorphous alloys [37][38][39][40][41][42] and Ti-V-based multiphase alloys [43][44][45][46][47][48][49][50]. Their performances differ greatly in terms of specific capacity, activation, rate dischargeability, and cyclic lifetime.…”

LaNi5 related AB5 compounds: Structure, properties and applications

“…In 1970, the alloy LaNi 5 , able to store more than 6 H/f.u. by the solid-gas route was discovered, rapidly tested as a negative electrode [94][95][96][97] in alkaline medium and patented in 1975. The binary alloy is however subject to rapid corrosion, and many studies were then performed to stabilize the intermetallic in alkaline medium [98][99][100][101][102][103].…”
