Aqueous Zn‐ion batteries (AZIBs) are regarded as a promising alternative to the widely used lithium‐ion batteries in large‐scale energy storage systems. The researches on the development of novel aqueous electrolyte to improve battery performance have also attracted great interest since the electrolyte is a key component for Zn2+ migration between cathode and anode. Herein, we briefly summarized and illuminated the recent development tendency of aqueous electrolyte for AZIBs, then deeply analyzed its existing issues (water decomposition, cathode dissolution, corrosion and passivation, and dendrite growth) and discussed the corresponding optimization strategies (pH regulation, concentrated salt solution, electrolyte composition design, and functional additives). The internal mechanisms of these strategies were further revealed and the relationships between issues and solutions were clarified, which could guide the future development of aqueous electrolytes for AZIBs.

Biopolymers derived from seaweed are good anticorrosive, antibacterial and anticancer agents. These biopolymers family includes the k-Carrageenan with good potential anticorrosive feature that is extracted from the red seaweed Acanthophora spicifera -Rhodophyceae. To obtain the best corrosion inhibition properties the k -Carrageenan hybrid composite with gelatin was prepared by sol-gel method. In the present study, two natural compounds have been used to prepare the proposed hybrid composite material. Such as, a self-assembled multilayer coating for medical grade stainless steel (SS) 304 were formed as substrate which can resist successfully to mild condition (3.5 wt % of NaCl) in the chosen electrolyte medium. The analysis by FT-IR confirms the hybridation of gelatin and biopolymer of k -Carrageenan. The electrochemical results revealed that the coated SS 304 is a promising corrosion inhibition with an efficiency up to 97 % at 24h and up to 65% at 227 h.The Eoc values from open circuit potential analysis indicated the occurrence of passivation on the surface due to hybrid composite coating. Further, the electrochemical impedance spectroscopy showed that the resistance of hybrid composite is higher than the bare steel showing Rct of 6.1 k  cm 2 and 2.1 k  cm 2 , respectively. The microstructural analysis by Scanning Electron Microscopy (SEM) and atomic force microscopy (AFM) confirmed that the coating surface have better corrosion resistance than SS 304 bare metal.

“…A new nickel-phosphorous self-healing coating process, which promises enhanced material properties and a low toxicity production process compared to the chromium-based equivalent is proposed [15]. The introduction of microgels comprised of nickel salts and sodium hypophosphite into Ni-P matrices results in the surface functionalisation by the introduction of self-healing properties.…”

Ni-P\alginate microgels coatings, as potential metallic protective coatings with self-healing properties, were deposited by the electroless method. The alginate microgels contained nickel chloride and sodium hypophosphite. It was proven that the reduction of nickel ions released from the microgels is possible on the steel and NiP coating surface. The self-healing effect of this system was studied by X-ray fluorescence (XRF), chronoamperometry and scanning vibrating electrode technique (SVET). An improved corrosion protection observed here is attributed to the reduction of nickel ions to metallic nickel on the tested surfaces. Differences in the surface concentration of nickel and phosphorous species in the corrosion tested coatings with and without microgels, as evaluated using X-ray Photoelectron Spectroscopy (XPS), provided substantial evidence for the formation of a NiP coating from the compounds included in the microgels.
