5results about How to "Reduce oxidative decomposition" patented technology

The application provides a battery electrolyte, comprising an additive component, the additive component comprising a nitrogen-containing heteroatom bridged ring structure, fluorine-containing acid root ions and / or fluorine-containing imine negative ions. The application modifies the electrolyte by selecting a specific additive component to form a stable and firm CEI film on the positive electrode surface to protect the electrode structure, and introduces fluorinated anions to enhance the association of anions and electrolyte solvent molecules, so as to improve the oxidation stability of the electrolyte. The modified electrolyte can be used to solve the instability of high-nickel ternary materials during the cycle process and the problem that the traditional electrolyte is prone to oxidative decomposition at high voltage, so as to improve the cycle life and rate performance of the ternary lithium battery at high voltage. The application is helpful to improve the oxidation stability of the electrolyte, reduce the charge transfer impedance and interface impedance, improve the ion diffusion rate, and enhance the stability of the electrode material structure.

This invention relates to the field of packaging bag technology, specifically to a moisture-proof and antibacterial composite packaging bag for traditional Chinese medicine. It comprises an outer protective film layer, a middle buffer transition layer, a moisture-proof barrier layer, an antibacterial functional layer, and an inner contact film layer. These layers are arranged from the outside in. The outer protective film layer, middle buffer transition layer, moisture-proof barrier layer, antibacterial functional layer, and inner contact film layer are composited using food-grade adhesives. The middle buffer transition layer is made of low-density polyethylene elastic film. The moisture-proof barrier layer is composited with polyvinyl alcohol high-barrier film and passivated aluminum foil film. The antibacterial functional layer uses food-grade polyolefin film as the substrate. The inner contact film layer uses food-grade polyethylene film. This invention has the following advantages: it integrates multiple benefits such as wear resistance, long-lasting moisture and oxygen barrier, active antibacterial properties, and safety and non-toxicity. Its service life and protective effect are far superior to traditional single-layer and ordinary double-layer packaging.

The invention relates to an organic additive oxidation resistant insoluble anode for PCB electroplating and a preparation method thereof, and belongs to the technical field of insoluble anodes for PCB electroplating. Comprising a titanium substrate and an insoluble anode coating on the surface of the titanium substrate, the insoluble anode coating is composed of a middle layer and a surface layer which sequentially cover the surface of the titanium substrate, the middle layer is an iridium-doped mesoporous tin dioxide-tantalum dioxide composite layer, and the surface layer is a nitrogen-doped mesoporous carbon-coated metal oxide composite layer. The organic additive oxidation resistance and the electrochemical performance of the insoluble anode can be remarkably improved.

This utility model discloses a composite film fresh-locking bag for packaging fruit juice, comprising a bag body and a cap; the bag body is formed by heat sealing a composite film; the film layer structure of the composite film includes a barrier antibacterial substrate layer, an adhesive layer, and a heat-sealing layer arranged sequentially from the outside to the inside; wherein, the barrier antibacterial substrate layer is a five-layer co-extruded biaxially oriented nylon film, arranged sequentially from the outside to the inside as a printed composite layer, a first barrier layer, a barrier core layer, a second barrier layer, and an antibacterial composite layer. This utility model packaging bag has good oxygen barrier and antibacterial properties, effectively reducing the contact between fruit juice and outside air, slowing down the oxidative decomposition and spoilage of nutrients in the fruit juice, and maintaining its nutritional components and fresh taste. Furthermore, the barrier antibacterial substrate layer of the biaxially oriented nylon film using the structure of this utility model has good puncture resistance, effectively reducing losses caused by bag bursting, which is beneficial for the storage and transportation of bagged fruit juice.
