“…Ni–Cd battery cells are the mature technology of the low-cost batteries, and are famous for low-cost microelectronic devices, MEH and WSNs. The nickel–cadmium (Ni–Cd) battery contains nickel oxide, metallic cadmium as the cathode and anode, respectively, and potassium hydroxide as the electrolyte [ 87 ]. Nickel is a silver–white metal, and one of the four elements that are magnetic at room temperature.…”

This paper reviews energy storage systems, in general, and for specific applications in low-cost micro-energy harvesting (MEH) systems, low-cost microelectronic devices, and wireless sensor networks (WSNs). With the development of electronic gadgets, low-cost microelectronic devices and WSNs, the need for an efficient, light and reliable energy storage device is increased. The current energy storage systems (ESS) have the disadvantages of self-discharging, energy density, life cycles, and cost. The ambient energy resources are the best option as an energy source, but the main challenge in harvesting energy from ambient sources is the instability of the source of energy. Due to the explosion of lithium batteries in many cases, and the pros associated with them, the design of an efficient device, which is more reliable and efficient than conventional batteries, is important. This review paper focused on the issues of the reliability and performance of electrical ESS, and, especially, discussed the technical challenges and suggested solutions for ESS (batteries, supercapacitors, and for a hybrid combination of supercapacitors and batteries) in detail. Nowadays, the main market of batteries is WSNs, but in the last decade, the world’s attention has turned toward supercapacitors as a good alternative of batteries. The main advantages of supercapacitors are their light weight, volume, greater life cycle, turbo charging/discharging, high energy density and power density, low cost, easy maintenance, and no pollution. This study reviews supercapacitors as a better alternative of batteries in low-cost electronic devices, WSNs, and MEH systems.

“…In a novel approach, nickel sulfide and cadmium sulfide nanoparticles were synthesized from nickel‐cadmium batteries by using sulfate‐reducing bacteria. The synthesis was found to be dependent on the initial concentration of cadmium, and produced nanoparticles of size 2–6 nm 15.…”

Waste materials are byproducts of modern technology-driven lifestyle of mankind. They are impossible to be eliminated entirely, and often recycling of these materials into more useful products is the best way to handle them. In the last two decades, engineered nanomaterials have found application in various fields of research due to their small size and unique physical, chemical, electrical, and magnetic properties. They have potential to be used in various fields of science and technology from bench scale to industrial scale. In this review, the fabrication of nanomaterials using waste material as feedstock is elaborated. Various techniques available for nanomaterial synthesis, their application, and potential challenges of waste-derived engineered nanomaterials are described. This field of research is highly relevant nowadays as this could prove to be a versatile and practical solution of waste management problems.

“…In the last decade, an increased number of studies have investigated Cd extraction from spent batteries by implementing non-metallurgical approaches. These approaches include bacterially-assisted recovery [6,7], microbial metal enrichment and recovery [8] and selective separation using glycine as an eco-friendly leachant [9]. Usually, Cd nanoparticles [7] or CdS nanoparticles [9] are obtained as outputs of these Cd extraction methods.…”

Usually, Cd nanoparticles [7] or CdS nanoparticles [9] are obtained as outputs of these Cd extraction methods. Bacterially-assisted recovery is, however, usually time-consuming, and a low-concentration of C-ions in a water-based solution are required for the realisation of this process.…”

Alkaline nickel-cadmium batteries are among the most used industrial high-power sources. Despite stricter environmental requirements, nickel-cadmium batteries still remain as the main choice for highly reliable power sources for heavy-loaded equipment. Therefore, recovery of cadmium (Cd) from spent batteries is a challenge for the modern recycling industry, particularly as it displays high bio-toxicity. The present study describes a new green approach for Cd recovery from cadmium oxide (CdO). The paper discusses using a ternary chloride composition consisting of calcium, potassium and sodium chloride, thereby avoiding the release of Cd vapour from the reaction volume during the reduction reaction from CdO. For the protective slag layer during the reduction process (which occurs at 650 °C), a 0.515:0.0796:0.405 molar ratio of CaCl2:KCl:NaCl was chosen, with the aim of achieving a melting point at 483 °C. To describe phase and elemental composition of obtained products X-ray diffraction analysis and energy dispersive X-ray spectroscopy, respectively, were applied. Electron and optical microscopy were used for morphological observations. The presence of the metallic Cd was noted. During the reduction reaction, it was noted that slag separated into two parts: a protective upper layer and bottom layer. It was also noted that metallic Cd accumulated with increasing reaction time in the bottom part of the slag.
