Electrode with active material layers for mechanical safety performance
A recently granted patent (Publication Number: US12015118B2) discloses an innovative electrode design for electrochemical devices. The electrode comprises a current collector, a first layer made of a specific material, and a second layer made of another material. The first layer, with a particle size of less than 40 µm, is positioned between the current collector and the second layer. The total compaction density of both layers must exceed 3.2 g/cc, ensuring optimal performance.
Furthermore, the patent details various aspects of the electrode design, including the thickness of the first layer relative to the particle size, the ratio of particle sizes between the two materials, and the specific materials that can be used for each layer. The electrode's compaction density requirements, with the first layer having a lower density than the second layer, are crucial for achieving the desired performance in electrochemical devices. This patented technology offers a promising solution for enhancing the efficiency and reliability of electronic devices through improved electrode design and material selection.
