The effects of Cs₂CO₃ addition in a KOH-based electrolyte were investigated for applications in nickel/metal hydride batteries. Both MgNi-based and Laves phase-related body-centered cubic solid solution metal hydride alloys were tested as the anode a...

Microstructures of a series of La-Mg-Ni-based superlattice metal hydride alloys produced by a novel method of interaction of a LaNi₅ alloy and Mg vapor were studied using a combination of X-ray energy dispersive spectroscopy and electron backscatter...

Due to variations among the cells, large lithium ion batteries (LIB) such as those in battery energy storage stations (BESS) and electric vehicles (EVs) must have an equalizer (EQU) circuit to balance the cell voltages. In spite of their significant...

Electrochemical performances of a high-capacity and long life β-α core-shell structured Ni_0.84Co_0.12Al_0.04(OH)₂ as the positive electrode active material were tested in a pouch design and compared to those of a standard β-Ni_0.91Co_0.045Zn_0.045(OH)₂. T...

As a concept for electrode architecture in high power lithium ion batteries, self-supported nanoarrays enable ultra-high power densities as a result of their open pore geometry, which results in short and direct Li⁺-ion and electron pathways. Vertica...

In this study, boron, a metalloid element commonly used in semiconductor applications, was added in a V-containing Zr-based AB₂ metal hydride alloy. In general, as the boron content in the alloy increased, the high-rate dischargeability, surface exch...

High-power cylindrical nickel metal/hydride batteries using a misch metal-based Al-free superlattice alloy with a composition of La_11.3Pr_1.7Nd_5.1Mg_4.5Ni_63.6Co_13.6Zr_0.2 were fabricated and evaluated against those using a standard AB₅ metal hydride all...

The effects of seven constituent phases—CeNi₃, NdNi₃, Nd₂Ni₇, Pr₂Ni₇, Sm₅Ni₁₉, Nd₅Co₁₉, and CaCu₅—on the gaseous phase and electrochemical characteristics of a superlattice metal hydride alloy made by induction melting with a composition of Sm₁₄La_5.7...

Rutile FeOF was used as a conversion-type cathode material for Li-ion batteries. In the present study, 0.6Li, 1.4Li, and 2.7Li per mole lithiation reactions were carried out by changing the electrochemical discharge reaction depth. The thermal charac...

Effective prognosis of lithium-ion batteries involves the inclusion of the influences of uncertainties that can be incorporated through random effect parameters in a nonlinear mixed effect degradation model framework. This study is geared towards the...

Contemporary pursuits in electronics include the miniaturization as well as flexibilization of devices. Although there are a large number of different thin and flexible electrochemical batteries, only a few can boast the possibility of working in hig...

The responses of one AB₅, two AB₂, four A₂B₇, and one C14-related body-centered-cubic (BCC) metal hydrides to an alkaline-etch (45% KOH at 110 °C for 2 h) were studied by internal resistance, X-ray diffraction, scanning electron microscope, inductive...

The performance of cylindrical cells made from negative electrode active materials of two selected AB₂ metal hydride chemistries with different dominating Laves phases (C14 vs. C15) were compared. Cells made from Alloy C15 showed a higher high-rate p...
