A comprehensive overview of electric vehicle batteries market

open access: yese-Prime: Advances in Electrical Engineering, Electronics and Energy, 2023
As there is growth in the population rate in the past few years, the number of vehicles on the roads has also increased. Thus, emissions of CO2 and hydrocarbons have risen, drastically. This problem has led to the success of the battery market, mostly in

Kinetics of Hydride Transfer from Metal-Free Hydride Donors to CO2

open access: yes, 2020
Selective reduction of CO2 to formate represents an ongoing challenge in photoelectrocatalysis. To provide mechanistic insights, we investigate the kinetics of hydride transfer (HT) from a series of metal-free hydride donors to CO2.

Metal-hydride hydrogen compressors for laboratory use

open access: yes, 2020
The development of commercial applications of hydrogen at high pressure (300–700 + bar), for example in fuel cell vehicles and associated filling stations, necessitates the study of hydrogen capacity, and the safety of materials at pressures well above ...

A Transition State Theory Perspective on the Relation of Reversible Metal Hydride First-Order Kinetics to Equilibrium Thermodynamics

open access: yes, 2021
In the event of hydrogen desorption from reversible metal hydrides, equilibrium thermodynamics exert a rate-limiting effect: if system pressure reaches equilibrium pressure, the reaction rate becomes zero. This is usually dealt with by an empiric term of

Techno-Economic Analysis of High-Pressure Metal Hydride Compression Systems

open access: yesMetals, 2018
Traditional high-pressure mechanical compressors account for over half of the car station’s cost, have insufficient reliability, and are not feasible for a large-scale fuel cell market.

Experimental and Computational Investigation of the Aerobic Oxidation of a Late Transition Metal-Hydride

open access: yes, 2019
The rational development of homogeneous catalytic systems for selective aerobic oxidations of organics has been hampered by the limited available knowledge of how oxygen reacts with important organometallic intermediates. Recently, several mechanisms for
