METHOD FOR PRODUCING ALL SOLID STATE BATTERY AND ALL SOLID STATE BATTERY - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240186586 titled 'METHOD FOR PRODUCING ALL SOLID STATE BATTERY AND ALL SOLID STATE BATTERY

Simplified Explanation

The abstract describes a method for producing an all solid-state battery with specific layers stacked in a particular order, including a transferring step using a transfer member with a transfer foil and transfer layer containing a binder.

• The method involves transferring a transfer layer onto the first current collector using a transfer member with a transfer foil and transfer layer.
• The transfer layer includes a binder, with a higher binder concentration on the surface opposite to the transfer foil side.

Potential Applications

The technology can be applied in the production of high-performance all solid-state batteries for various electronic devices, electric vehicles, and energy storage systems.

Problems Solved

1. Enhanced performance and stability of solid-state batteries. 2. Improved adhesion and conductivity between layers in the battery structure.

Benefits

1. Increased energy density and efficiency. 2. Longer lifespan and durability of batteries. 3. Safer operation due to the solid electrolyte layer.

Potential Commercial Applications

Optimizing All Solid-State Battery Production for Enhanced Performance

Possible Prior Art

There may be prior art related to methods for transferring layers in battery production processes, but specific information is not provided in this abstract.

How does the binder concentration affect the performance of the battery layers?

The abstract mentions a difference in binder concentration between the surface opposite to the transfer foil and the transfer foil side. It would be interesting to know how this concentration difference impacts the overall performance and characteristics of the battery layers.

What specific electronic devices or applications could benefit most from this technology?

While the abstract mentions potential applications in electronic devices, electric vehicles, and energy storage systems, it would be helpful to understand which specific devices or industries could see the most significant improvements or advancements with the implementation of this technology.

Original Abstract Submitted

a method for producing an all solid state battery including a first current collector, a first active material layer, a solid electrolyte layer, a second active material layer and a second current collector stacked in this order, the method comprising: a transferring step of transferring a transfer layer onto the first current collector by using a transfer member including a transfer foil and the transfer layer, the transferring step being included in a step of forming at least one layer of the first active material layer, the solid electrolyte layer, and the second active material layer, and the transfer layer includes a binder, and in a thickness direction, a binder concentration of a surface portion on opposite side to the transfer foil is higher than a binder concentration of a surface portion on the transfer foil side.
