ELECTRODE FOR SECONDARY BATTERY AND SECONDARY BATTERY - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240194851 titled 'ELECTRODE FOR SECONDARY BATTERY AND SECONDARY BATTERY

Simplified Explanation: The electrode for a secondary battery consists of a substrate with an active material layer. The active material layer has one or more grooves on its surface, extending linearly perpendicular to its thickness. These grooves have open portions on the periphery of the layer, with a smaller cross-sectional area in the second region compared to the first region.

  • The electrode for a secondary battery has grooves formed in the active material layer.
  • The grooves extend linearly perpendicular to the thickness direction of the active material layer.
  • The grooves have open portions on the periphery of the active material layer.
  • The second region of the groove has a smaller cross-sectional area than the first region.

Original Abstract Submitted

an electrode for a secondary battery includes a substrate and an active material layer. the active material layer is placed on a surface of the substrate. in a surface of the active material layer, one or more grooves are formed. the groove extends linearly in a direction perpendicular to a thickness direction of the active material layer. the groove has an open portion on a periphery of the active material layer. the open portion opens in the direction perpendicular to the thickness direction. the groove includes a first region and a second region. the second region is interposed between the open portion and the first region. in a cross section perpendicular to a direction in which the groove extends, the first region has a first cross-sectional area, and the second region has a second cross-sectional area. the second cross-sectional area is smaller than the first cross-sectional area.
