  • The metal layer of the connection laminate layer connects the cathode terminal of one unit cell to the anode terminal of another unit cell.

Key Features and Innovation:

  • High volumetric efficiency battery module design.
  • Stacked and connected unit cells with a connection laminate layer.
  • Metal layer in the connection laminate layer for electrical connections between unit cells.

Potential Applications:

  • Electric vehicles.
  • Portable electronics.
  • Energy storage systems.

Problems Solved:

  • Low volumetric efficiency in traditional battery modules.
  • Inefficient electrical connections between unit cells.

Benefits:

  • Increased energy density.
  • Improved overall battery performance.
  • Enhanced reliability and durability.

Commercial Applications:

The technology can be utilized in various industries such as electric vehicles, consumer electronics, and renewable energy storage systems, potentially revolutionizing the way we power our devices and vehicles.

Questions about Battery Module Technology: 1. How does the connection laminate layer improve the efficiency of the battery module? 2. What are the key advantages of using stacked and connected unit cells in a battery module?


Original Abstract Submitted

To provide a battery module with high volumetric efficiency. A battery module comprising stacked and connected unit cells each comprising a power generation element, a cathode terminal, and an anode terminal disposed on the opposite side of the cathode terminal of the power generation element, wherein a connection laminate layer including a resin layer, a metal layer and a resin layer in this sequence, is disposed between the unit cells, and wherein the metal layer of the connection laminate layer is electrically connected to the cathode terminal of one adjacent unit cell and the anode terminal of the other unit cell.
