  • Negative electrode material for lithium-ion secondary battery and method for producing negative electrode material for lithium-ion secondary battery
    Patent number: 11646406
    Abstract: A negative electrode material for a lithium-ion secondary battery is disclosed which contains a mass of graphite particle spherical aggregates in which a plurality of flat graphite particles are aggregated. The mass of the graphite particle spherical aggregates has an average circularity, D90/D10, and a crystallite size Lc (004) within a predetermined range, and the proportion of the graphite particle spherical aggregates in which the largest flat graphite particle observed on the outermost surface has a circle equivalent diameter of 2 ?m to 12 ?m in graphite particle spherical aggregates having a circle equivalent diameter of 10 ?m or more when observed by SEM is 80% or more.

  • Gateway card, gateway device, method of controlling gateway card, and computer product
    Patent number: 8862915
    Abstract: A gateway card is connected to an information processor, and receives and transmits data between different networks. The information processor has a normal power mode and a power saving mode. A switching unit connects a memory with the information processor if the information processor is in the normal power mode, or to the gateway card if the normal power mode of the information processor is changed to the power saving mode.
