An apparatus and method are described for a convenience towel. The disclosed embodiments describe, amongst other things, for example, a towel that may be draped over a water bottle. The towel may comprise a variety of shapes and may have one or more layers. The towel may have an opening that may allow a bottle spout to protrude making it available to consumers. In addition, the towel may have a handle or loop for gripping.

Disclosed herein relates to an electrode sheet drying device including a guide roller having a plurality of perforated holes formed on the outer circumferential surface, and the guide roller is configured to vacuum cling an electrode sheet to prevent an electrode sheet from being lifted from the guide roller during a drying process, thereby having an effect of mitigating the occurrence of creases in a non-coated part and preventing lifting of a current collector and the occurrence of cracks.

Drying a planar substrate such as paper sheet goods for packing materials includes layering a phase change material (PCM) on a substrate, in which the substrate has a moisture content and adapted for moisture removal to form a planar medium. A drying process disposes the substrate adjacent to a plurality of rollers and heat the layered substrate to a predetermined temperature based on a specific heat of the PCM. The rollers advance the layered substrate in series through pocket ventilation regions between the heat transfer elements, such that the pocket ventilation regions permit drying of the substrate enhanced by the specific heat of the temperature sensitive material. Upon drying, the layered substrate forms the planar medium suitable for use as a packing medium or other suitable application. The pocket ventilation regions are based on the PCM to facilitate drying and eradication of moisture from the paper planar substrate.
