Description
technical field [0001] This technology relates to batteries, battery packs, electronic equipment, electric vehicles, power storage devices, and power systems. Background technique [0002] In recent years, various electronic devices such as mobile phones and portable information terminal devices (Personal Digital Assistants: PDAs) are widely used, and further miniaturization of the electronic devices is desired. In order to meet this demand, a battery with high energy density has been developed as a power source. [0003] As a technique for achieving higher energy density, there is a technique for increasing the area density of the active material layer by increasing the thickness of the electrode film. However, if this technique is applied to a wound-type battery element, there is a concern that the electrode may be broken in the winding portion. Therefore, techniques for maintaining windability even in thick electrodes with high area density have been studied by controll...
