The synthesis of novel zinc electrodes has been successfully implemented by using the electroplating method with the aid of inorganic additives in the electroplating solution. The selected inorganic additives are indium sulfate, tin oxide, and boric acid. From X-ray diffraction results, these synthesized zinc electrodes prefer (002) and/or (103) crystallographic orientations, representing basal morphology and high resistance to dendrite growth.

The Zn anode in secondary aqueous batteries suffers from dendrite formation and corrosion. In this work, dendrite formation was suppressed by using a simple but new gel electrolyte containing fumed silica and an additive. The dendrite suppression was evidenced by chronoamperometry and ex situ scanning electron microscopy examinations.

Article Synopsis
  • Novel zinc anodes are created using electroplating techniques with various organic additives, including CTAB, SDS, PEG, and TU, each impacting the anode's properties.
  • Characterization techniques like powder X-ray diffraction and scanning electron microscopy reveal that these additives lead to different crystallographic orientations and surface textures, affecting electrochemical performance.
  • The Zn-SDS anode stands out as the best option for use in rechargeable hybrid aqueous batteries, showing significantly lower corrosion rates and better capacity retention after extensive cycling compared to traditional zinc foil.

A scaling-up investigation of a sulfur-polymer cathode for rechargeable lithium-sulfur batteries is reported. The proposed procedure uses a low cost aluminium current collector and is suitable for mass production of a composite cathode, with sulfur loading levels of up to 5.9 mg cm(-2), and good electrochemical performance.
