  • Patent number: 11329323
    Abstract: A manufacturing method of a secondary battery is provided to improve a manufacturing efficiency of a non-rectangular electrode. The manufacturing method is provided for a secondary battery and includes forming the non-rectangular electrode. The step of forming the electrode includes, prior to forming an electrode precursor by applying an electrode material layer raw material to a metal sheet material that becomes a current collector, controlling a wettability of a local portion of a surface of the metal sheet material to the electrode material layer raw material and forming a wettability control region in the local portion. The local portion becomes a cutaway region of the non-rectangular electrode.

  • Patent number: 8606445
    Abstract: An information control device for an electric vehicle including a vehicle-mounted battery that is charged with electric power supplied from a power supply provided at an outside of the vehicle includes a lock operation detector, a remaining power detector, and a notification controller. The lock operation detector is configured to detect a lock operation of a door lock mechanism of the vehicle. The remaining power detector is configured to detect a remaining power amount of the vehicle-mounted battery. The notification controller is configured to control a notifying device to make a notification to the outside of the vehicle. The notification is indicative of information that recommends power charge of the vehicle-mounted battery if the remaining power amount is small when the door lock mechanism has been locked or is to be locked, based on detection results of the lock operation detector and the remaining power detector.
