Description
Application of Multilayer Polymer Three-Dimensional Electrode 0503216 in Energy
The invention relates to the fields of material preparation, electrode preparation and electrochemical energy storage, mainly preparing electrodes with layered and single-layer three-dimensional porous structure. Specifically, three-dimensional porous electrodes with multi-layer structure are prepared by scraper coating method and porous material preparation method, and the electrodes are applied to the anode of lithium-sulfur battery and the cathode of lithium-ion battery, so as to improve the electrochemical stability of lithium-sulfur battery and lithium-ion cathode.
In the field of energy storage, battery electrode is one of the most important components in the field of chemical energy storage. However, in the process of electrode reaction, the conversion efficiency of reactants and the total amount of reactants directly affect the energy storage capacity and cycle life of the battery. For example, in a lithium-sulfur battery, the sulfur content of the positive active material directly affects the reversible discharge capacity of the lithium-sulfur battery; the coating amount of spherical carbon anode in various lithium ion batteries also affects the capacity of the whole lithium ion battery. In the preparation process, the amount of active materials in the electrode is usually increased by increasing the coating thickness. However, while increasing the electrode, the impedance of the electrode increases exponentially and the ionic conductivity of the electrode decreases rapidly. These factors seriously restrict the development and commercial application of large-capacity lithium ion batteries.
The invention aims to prepare an electrode capable of loading active substances with increased content by changing the overall structure of the electrode and the components of receptors in the electrode.
