BATTERY - A simplified explanation of the abstract

This abstract first appeared for US patent application 18606425 titled 'BATTERY

The abstract describes a patent application for a negative electrode with a honeycomb core structure. The core includes a first face, a second face, a partition, and a circumferential wall. The partition separates 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. The hollow cells in the central part of the core have a first average filling factor, while those in the inner circumferential part have a second average filling factor that is 2.1 times or more the first average filling factor.

• The negative electrode has a honeycomb core structure with a first face, a second face, a partition, and a circumferential wall.
• The partition separates hollow cells in the core, with a first layer covering part of it.
• The central part of the core has hollow cells with a first average filling factor, while the inner circumferential part has a second average filling factor that is significantly higher.
• The innovation aims to optimize the filling factor distribution within the honeycomb core structure for improved performance.

Potential Applications: - Lithium-ion batteries - Electric vehicles - Energy storage systems

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.
