Low-Emission Cylindrical-Winding Battery Design - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240204239 titled 'Low-Emission Cylindrical-Winding Battery Design
The present document describes a low-emission cylindrical-winding battery design. The battery design is a rolled and stacked battery, with two or more winding rolls of cathode and anode layers separated by insulation layers, the winding rolls also being separated by a distance with the distance, in some embodiments, filled with a dielectric material. A first winding roll of first stacked anode and cathode layers and a second winding roll of second stacked anode and cathode layers are wound in a direction around a central axis of the battery. The first winding roll of first stacked anode and cathode layers follows a first stacking order with the anode and cathode layers alternating. The second winding roll of second stacked anode and cathode layers follows a second stacking order with the anode and cathode layers alternating opposite to the first stacking order. The alternating stacking orders cause the battery to produce a reduced h-field when compared with a battery having non-alternating stacking orders.
