METHOD FOR PRODUCING LAYERED BATTERY, AND LAYERED BATTERY - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240136691 titled 'METHOD FOR PRODUCING LAYERED BATTERY, AND LAYERED BATTERY

Simplified Explanation

The present disclosure describes a method for producing a layered battery with high structural reliability. The method involves preparing an electrode layered body, injecting a liquid electrolyte, sealing the injection port, performing battery treatment, forming a penetration hole, and sealing the injection port again.

• Electrode layered body preparation:

 - Prepare a body with multiple electrode layers in the z-axis direction.

• Liquid injection and sealing:

 - Inject liquid electrolyte into the electrode body through a resin frame with an injection port.
 - Seal the injection port with a resin layer after injection.

• Battery treatment and penetration hole formation:

 - Charge or age the battery after sealing.
 - Form a penetration hole in the resin layer to communicate with the injection port.

• Final sealing:

 - Seal the injection port while covering the penetration hole with a second member containing a resin and metal layer.
