ELECTRODE MANUFACTURING METHOD - A simplified explanation of the abstract

This abstract first appeared for US patent application 18264264 titled 'ELECTRODE MANUFACTURING METHOD

Simplified Explanation

The manufacturing method of electrodes for a secondary battery includes a vibration treatment step and a press step to increase capacity density and safety of the battery.

• Vibration treatment step: Supplies vibration to the electrode before the press step.
• Press step: Applies pressure to compress the active material layer in the electrode.

Potential Applications

This technology can be applied in the manufacturing of secondary batteries for various electronic devices such as smartphones, laptops, electric vehicles, and energy storage systems.

Problems Solved

1. Increased capacity density of secondary batteries. 2. Improved safety and reliability of secondary batteries.

Benefits

1. Higher capacity density. 2. Enhanced safety and reliability. 3. Improved performance of secondary batteries.

Potential Commercial Applications

Optimizing the manufacturing process of secondary batteries can lead to increased production efficiency and cost-effectiveness, making it attractive for battery manufacturers and suppliers.

Possible Prior Art

One possible prior art could be the use of various compression techniques in electrode manufacturing processes to improve battery performance and safety.

How does the vibration treatment step contribute to the increased capacity density of the secondary battery?

The vibration treatment step helps to evenly distribute the active material within the electrode, leading to a more compact and efficient battery design.

What are the specific safety benefits of the manufacturing method described in the patent application?

The manufacturing method ensures that the active material layer in the electrode is compressed uniformly, reducing the risk of internal short circuits and thermal runaway in the battery.

Original Abstract Submitted

An object of one embodiment of the present invention is to achieve a manufacturing method which can increase capacity density of a secondary battery. Another object is to provide a manufacturing method of a highly safe or reliable secondary battery. The manufacturing method of electrodes (a positive electrode and a negative electrode) of a secondary battery includes a vibration treatment step for supplying vibration to the electrode and a press step for applying pressure to the electrode to compress an active material layer in the electrode. The vibration treatment step is performed before the press step.
