MANUFACTURING METHOD AND MANUFACTURING APPARATUS OF ELECTRODE STRUCTURE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18176136 titled 'MANUFACTURING METHOD AND MANUFACTURING APPARATUS OF ELECTRODE STRUCTURE

Simplified Explanation

The manufacturing method of an electrode structure involves rolling an active material-containing layer in a belt-like member, applying tension in the longitudinal direction, and enlarging an uncoated region using a projection on a roller.

  • The active material-containing layer is rolled in a belt-like member.
  • Tension is applied in the longitudinal direction between a pulling unit and a rolling unit.
  • A projection on a roller pushes the uncoated region, enlarging it in the longitudinal direction.
  • The projection length is larger than the thickness of the active material-containing layer.

Potential Applications

This technology can be applied in the manufacturing of electrodes for various electrochemical devices such as batteries, supercapacitors, and fuel cells.

Problems Solved

1. Ensures uniform coating of active material on the current collector. 2. Prevents delamination or uneven distribution of the active material in the electrode structure.

Benefits

1. Improved electrode performance and efficiency. 2. Enhanced durability and stability of electrochemical devices. 3. Cost-effective manufacturing process.

Potential Commercial Applications

Optimizing Electrode Structure Manufacturing Process for Enhanced Performance

Possible Prior Art

Prior art may include methods for coating active materials on current collectors in electrode manufacturing processes, but specific techniques involving the use of a projection to enlarge uncoated regions may not be commonly known.

Unanswered Questions

How does the projection on the roller prevent delamination of the active material-containing layer?

The projection helps to push the uncoated region, ensuring a more uniform coating and adhesion of the active material to the current collector, thus reducing the risk of delamination.

What are the specific parameters for adjusting the tension in the longitudinal direction during the manufacturing process?

The specific tension levels may vary depending on factors such as the type of active material, current collector material, and desired electrode structure properties. Further research and experimentation may be needed to determine the optimal tension for different applications.


Original Abstract Submitted

In a manufacturing method of an electrode structure of an embodiment, in a belt-like member in which an uncoated region not coated with an active material-containing layer is formed in one of long edges and its vicinity in a current collector, the active material-containing layer is rolled, and a tension in a longitudinal direction is applied to the belt-like member between a pulling unit pulling the belt-like member and a rolling unit rolling the active material-containing layer. In the method, the uncoated region is pushed by a projection projecting to an outer peripheral side in a roller between the rolling unit and the pulling unit, thereby enlarging the uncoated region in the longitudinal direction. A projection length of the projection to the projection end is larger than the thickness of the rolled active material-containing layer.
