The densities of argon metastable (3)P(2), and resonance (1)P(1), (3)P(1) states were measured along a cylindrical magnetron discharge radius by absorption spectroscopy using a narrow bandwidth single mode diode laser. The theoretical treatment includes calculations of the rates of numerous excitation and decay processes based on nonlocal electron kinetics, and analysis of the transport equations for the resonance and metastable atoms. The solution technique of the Biberman-Holstein equation of radiation transport is developed in conformity with magnetron discharge geometry. The radial profile of the effective lifetime is obtained, taking into account radiation escape on the inner and outer electrodes. The distinction in formations of the radial profiles of the resonance and metastable atoms caused by specifics of radiation transport and diffusion is demonstrated. The results of experiments and calculations are compared.

Manganese oxides are a promising cathode material for aqueous zinc-ion batteries (AZIBs), but thin-film configurations remain underexplored. This study investigates the electrochemical dynamics of 60 nm thin MnO thin films, fabricated via RF magnetron reactive sputtering. It addresses the highest reported capacity (25 mAh/g) in thin film form, stability over 500 cycles, effective performance across varying current rates, surpassing previous studies and challenges such as phase stability, and capacity fading over extended cycling, aiming to enhance uniformity, minimizing diffusion barriers for improved performance.

Aqueous zinc-ion batteries are an appealing electrochemical energy storage solution due to their affordability and safety. Significant attention has been focused on vanadium oxide cathode materials for ZIBs, owing to their high specific capacity, unique layered or tunnel structures, and low cost. Compared to traditional methods for preparing and assembling electrode materials, direct current (DC) magnetron sputtering allows direct synthesis and uniform deposition on current collectors, offering advantages such as simplicity, mild reaction conditions, and strong film adhesion.

Alloy-type anodes used in magnesium ion batteries (MIBs) have garnered significant attention in light of their substantial theoretical specific capacities and possible matchability with conventional electrolytes. However, the major challenges for alloy-type anodes are the sluggish transport kinetics as well as severe volume variations during the discharge/charge processes. Herein, we present a strategy for phase-structure modulation to fabricate a self-supporting In-Bi film through straightforward magnetron sputtering.
