Application: Spacers for electrodes, electrode stacks and batteries and systems and methods therefor (Patent ID: US20230411792A1)
The patent filed by Enovix Corp. describes a battery design with an electrode assembly consisting of unit cells stacked in succession, each unit cell comprising layers for electrode current collectors, electrode and counter-electrode materials, and separators. A subset of the unit cells includes spacer members between the electrode and counter-electrode current collector layers, with the counter-electrode active material located between the spacers in a defined plane. The design aims to improve battery performance and efficiency by optimizing the arrangement of active materials and components within the unit cells.
The secondary battery design also includes specific configurations for the electrode assembly, such as perpendicular axes for orientation, spacer members to create expansion gaps, and contact points between layers. The method of manufacturing the unit cells involves precise stacking of layers, placement of spacer members, and conforming separator ends to ensure proper alignment and functionality. By incorporating these features, the battery design aims to enhance cycling performance, accommodate material expansion, and optimize the arrangement of active materials for improved overall battery efficiency and longevity.
