  • Publication number: 20240030449
    Abstract: Provided is a production method of a coating composition for electrode, which is able to determine suitable conditions in a dispersion step of an electrode slurry for positive electrode for lithium ion battery, in terms of numerical values, and to enhance performances of the resulting battery. A production method of an electrode slurry for positive electrode for lithium ion secondary battery, including kneading at least a carbon material as an electroconductive material and a solvent into a dispersion, is disclosed. As for the carbon material-dispersed slurry, its alternating current impedance value immediately after the dispersion is controlled to a prescribed numerical value.

  • Patent number: 11750003
    Abstract: An information processing device that transmits information on an energy storage device and a power supply-related device in response to a request from the outside or as an event includes, an acquisition unit that acquires information including a state of the energy storage device or the power supply-related device through communication; a storage processing unit that stores the acquired information in a storage medium in association with information that identifies the energy storage device and the power supply-related device, respectively; and a transmission processing unit that transmits display information for collectively displaying the information stored in the storage medium for each system including the energy storage device and/or power supply-related device, or for each place where the energy storage device and/or power supply-related device is installed.
