Nickel metal hydride batteries for high power applications

Review: on rare-earth perovskite-type negative electrodes in nickel–hydride (Ni/H) secondary batteries

“…The Ni/MH battery also has a relatively high energy density (Wh L -1 ) but a rather low specific energy (Wh kg -1 ) when compared to the Li-ion battery as a result of the high density of its active materials in the anode (nickel-based alloys versus graphite) [4]. Thus, Ni/MH batteries are widely used in stationary applications, consumer electronics, power tools, hybrid and full electric road and rail vehicles because of its durability, abuse tolerance, compact size, and environmental friendliness [5][6][7][8]. On the other hand, Li-ion batteries are commonly used in applications where strict requirements in power and energy are needed, such as in electric vehicles and mobile phones [4,9].…”

Mn-substituted nickel hydroxide prepared by ball milling and its electrochemical properties

“…Although nickel-base batteries currently meet a strong competition by Liion batteries which have higher specific energy, they still occupy a unique position within the battery industry [1][2][3]. In order to extend the application of these batteries, it is important to reduce the price of nickel hydroxide at the same time improving its performance.…”

High-temperature characteristics of advanced Ni-MH batteries using nickel electrodes containing CaF2

“…The technical strengths of Ni-MH battery systems are recognized as high-power capability, long-term durability and high charge/discharge efficiency. Despite the emergence of lithium ion batteries and small, portable fuel cells, Ni-MH batteries continue to receive much attention because almost all of the commercial HEVs employ Ni-MH batteries due to their better combination of power output, capacity, life, reliability and cost [1][2][3][4][5][6][7][8].…”
