BATTERY AND BATTERY PRODUCTION METHOD - A simplified explanation of the abstract

This abstract first appeared for US patent application 18366022 titled 'BATTERY AND BATTERY PRODUCTION METHOD

Simplified Explanation

The abstract describes a battery design that includes multiple electrode bodies connected by a conductive material. Each electrode body consists of a metal current collector, an active material layer, and an electrolyte layer. The metal current collector has a connection surface that contacts the conductive material and a laminate surface that contacts the active material layer. The laminate surface has a smoother average roughness compared to the connection surface.

  • Battery design with multiple electrode bodies connected by a conductive material
  • Each electrode body consists of a metal current collector, active material layer, and electrolyte layer
  • Metal current collector has a connection surface and a laminate surface
  • Laminate surface has a smoother average roughness than the connection surface
  • Design improves adhesion between metal current collector and active material layer
  • Design enhances connectivity between electrode bodies via conductive material


Original Abstract Submitted

The battery of the present disclosure comprises a plurality of electrode bodies, wherein one of the electrode bodies and another of the electrode bodies are connected via a conductive material, each of the electrode bodies includes a metal current collector, an active material layer, and an electrolyte layer, the metal current collector has a connection surface which contacts the conductive material and a laminate surface which contacts the active material layer, and a ten-point average roughness of the laminate surface is less than a ten-point average roughness of the connection surface. According to the battery of the present disclosure, both adhesion between the metal current collector and the active material layer in the electrode body and connectivity between the electrode bodies via the conductive material can be achieved.
