“…Nonetheless, when estimated from the diameter of the cathode spots observed in figures 8(d) (∼2 mm) and 8(f ) (∼6 mm), maximum and minimum values of the current density of 16 and 1.8 A cm −2 are obtained. These compare well with the value of 9 A cm −2 based on the area of the negative glow reported by Arkhipenko et al [9] for atmospheric pressure nitrogen glow discharge between a tungsten rod (∅6 mm) and a hollow copper rod (∅36 mm) with a water cooled surface at the same current of 0.5 A. The variety of cathode spot patterns obtained by glow discharge under the same macroscopic conditions (gap geometry, pressure, glow current, gas flow rate and inter-electrode spacing) are a surprising result of this work.…”

“…As can be seen, the voltage-current curves are descending, whereas the power-current curves are ascending. Similar V -I and P -I trends have been reported for atmospheric pressure normal glow discharges in nitrogen and air by other authors [9,10,14,15].…”

“…In one series the nitrogen flow rate is 20 lpm and the current varies from 0.35 to 0.5 A; in the other series the current is 0.5 A and the gas flow rates are 10 and 20 lpm. In all the experiments the discharge voltage varies linearly with the gap length, with a slope of about 130 V cm −1 , also referred to as the electric field strength [9][10][11]. This value is comparable to the values of the electric field strength reported by Arkhipenko et al [9] for atmospheric pressure nitrogen glow discharge between tungsten and copper electrodes at currents similar to the ones used here.…”

This value is comparable to the values of the electric field strength reported by Arkhipenko et al [9] for atmospheric pressure nitrogen glow discharge between tungsten and copper electrodes at currents similar to the ones used here. Significantly lower particle production is found in the experiment at a gas flow rate of 20 lpm with respect to the experiment at a gas flow rate of 10 lpm, suggesting the cathode temperature is higher in the experiment at a lower flow rate (hot cathode).…”

“…The temperatures satisfy the inequality T gas < T vib < T exc . The excited atomic Cu levels are produced by electron collisions and consequently the values of T exc are close to the high electron temperature (about 1 eV in N 2 atmospheric pressure glow discharges) [9], although below it due to the loss of excited atoms by radiation and ionization. Similarly, vibrational levels of N 2 are produced by inelastic collisions with electrons and other gas molecules and consequently the values of T vib are between the gas temperature and the excitation temperature.…”

AbstractThis work is aimed at investigating the influence of the inter-electrode spacing on the production rate and size of nanoparticles generated by evaporating a cathode on an atmospheric pressure dc glow discharge. Experiments are conducted in the configuration of two vertically aligned cylindrical electrodes in upward coaxial flow with copper as a consumable cathode and nitrogen as a carrier gas. A constant current of 0.5 A is delivered to the electrodes and the inter-electrode distance spanned from 0.5 to 10 mm. Continuous stable nanoparticle production is attained by optimal coaxial flow convection cooling of the cathode. Both the particle production rate and the primary particle size increase with the inter-electrode spacing up to nearly 5 mm and strongly decrease with an increasing inter-electrode distance beyond 5 mm. Production rates in the range of 1 mg h −1 of very small nanoparticles (<10 nm) are attained by a micro glow discharge (<1 mm); while glow discharges of intermediate sizes (<5 mm) result in production rates ...

The pursuit of straightforward and cost‐effective methods for synthesizing high‐performance anode materials for lithium‐ion batteries is a topic of significant interest. This study elucidates a one‐step synthesis approach for a conversion composite using glow discharge in a nickel formate solution, yielding a composite precursor comprising metallic nickel, nickel hydroxide, and basic nickel salts. Subsequent annealing of the precursor facilitated the formation of the Ni@NiO composite, exhibiting exceptional electrochemical properties as anode material in Li‐ion batteries: a capacity of approximately 1000 mAh·g−1, cyclic stability exceeding 100 cycles, and favorable rate performance (200 mAh·g−1 at 10 A·g−1). Comparative analysis across various methods for synthesizing NiO‐based materials underscored the superiority of the Ni@NiO composite. Furthermore, an assessment of resource costs demonstrated the cost‐effectiveness and scalability of the approach in terms of resource consumption per Ah. Lastly, the integration of a Ni@NiO anode with an NMC532 cathode in a full battery highlights Ni@NiO's potential for conversion anodes, achieving a practical gravimetric energy density of 92 Wh kg−1.
