2 results about "Bismuth salts" patented technology

This invention discloses an electrolyte, its preparation method, and its application. The electrolyte comprises a deep eutectic solvent and an electrolyte salt. The deep eutectic solvent includes hydrogen bond acceptors and hydrogen bond donors, with a molar ratio of 1:(0.2-5). The electrolyte salt includes at least one of zinc, aluminum, magnesium, iron, calcium, manganese, cobalt, antimony, or bismuth salts. This electrolyte provides anions and cations that can act on the insertion and extraction of the positive electrode active material of the battery. The electrolyte has a wide voltage range and is a novel electrolyte system using a deep eutectic solvent. When used in aqueous batteries (e.g., with a zinc-containing negative electrode), it can suppress the formation of zinc dendrites, resulting in dendrite-free aqueous batteries with fewer side reactions. The resulting batteries exhibit good cycle stability and high coulombic efficiency.

This invention discloses a high-permeability cobalt-bismuth-nickel micro / nano soft magnetic material and its preparation method. The micro / nano soft magnetic material exhibits high permeability at ultra-high frequencies. The material is micrometer-scale and chain-like. In this invention, different amounts of cobalt, nickel, and bismuth salts, along with an alkali, are uniformly mixed in a reducing solution environment. A certain amount of complexing agent and surfactant are then added to orderly complex the ions through interaction, modifying the surface of the CoBiNi micro / nano particles. The liquid mixture is gradually heated to 150°C. o C-250 o C, hydrothermal reaction for 8-24 hours. This invention has the advantages of simple operation and low cost. The prepared micro-nano soft magnetic materials maintain high permeability in the ultra-high frequency and super-high frequency bands (1GHz-18GHz). After measurement by a vector network analyzer (VNA), the prepared CoBiNi micro-nano particles still maintain a permeability of over 3.00 at ultra-high frequencies of 16.04GHz-16.86GHz, and can reach a maximum of 4.27, which is dedicated to meeting the high permeability requirements of 5G communication materials at specific frequencies.
