“…2.6 nm size were observed, in agreement with the size previously obtained by TEM. The presence of diffuse rings in the electron diffraction pattern of Co1 also suggested an amorphous structure of the cobalt phase, as previously reported for CoNPs synthesized through similar colloidal methods [16][17][18]. HRTEM image of Co1 NPs and electron diffraction pattern.…”

“…They were able to use this material as an anode for alkaline rechargeable battery. 52,53 However, the material showed a discharge capacity of about 250 mAh g À1 , which was lower than that of the hydrogen storage alloy in commercial Ni/MH batteries. The electrochemical reaction mechanisms were also not clear.…”

The Ni/Co battery is a new electrochemical energy storage system for alkaline rechargeable batteries that has been attracting much attention due to its high energy density. This review presents the current R&D status of Co-based materials with a particular focus on Ni/Co batteries, including their underlying principles and the recent progress in Co-based materials (e.g., cobalt oxides and hydroxides, Co-based alloys, and some composites). It emphasizes the relationship of the composition, phase structure and electrochemical properties of Co-based materials that show promise in practical application due to their good electrode performance. The synthesis of novel Co-based materials in nanoscale and low dissolution of active materials into the alkaline solution during cycling are two essential factors favouring the application of this environmentally-friendly battery.

“…Also, they are widely used in other fields such as electronics, optoelectronics and magnetic due to their unique physical and chemical properties [11][12][13][14][15][16]. Since Mitov et al [17] report that Co-B amorphous alloy has electrochemical hydrogen absorption-desorption properties in alkaline rechargeable batteries, more and more efforts have been paid to investigate the electrochemical properties of various transition metal-metalloid compounds. Wang et al [18] report Co-S alloy by ball milling of Co and S powders and obtain the highest discharge capacity of 350 mAh g −1 and excellent cycle stability as a negative material for Ni/MH batteries.…”
