BATTERY - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240222679 titled 'BATTERY

The negative electrode in this patent application forms a honeycomb core, which consists of a first face, a second face, a partition, and a circumferential wall. The second face is opposite the first face, with the partition separating a plurality of hollow cells in a cross-section parallel to the first face. The separator includes a first layer covering part of the partition, with the hollow cells having different filling factors in the central part and the inner circumferential part.

• The negative electrode features a honeycomb core structure with different filling factors in the central and inner circumferential parts.
• The separator includes a first layer that covers part of the partition between the first and second faces.
• The second average filling factor in the inner circumferential part is at least 2.1 times greater than the first average filling factor in the central part.

Original Abstract Submitted

the negative electrode forms a honeycomb core. the honeycomb core includes a first face, a second face, a partition, and a circumferential wall. the second face faces the first face. the partition is formed between the first face and the second face. in a cross section parallel to the first face, the partition separates a plurality of hollow cells. the separator includes a first layer. the first layer covers at least part of the partition. the cross section parallel to the first face includes a central part and an inner circumferential part. the central part is surrounded by the inner circumferential part. in the central part, the hollow cells have a first average filling factor. in the inner circumferential part, the hollow cells have a second average filling factor. the second average filling factor is 2.1 times or more the first average filling factor.
