  • Patent number: 10243204
    Abstract: A negative electrode active material is provided for a lithium ion secondary battery having high initial charging/discharging efficiency. The negative electrode active material containing silicon and silicon oxide has two phases with different compositions therein. One of the two phases has a lower silicon element concentration than the other phase, and is a fibrous phase forming a network structure in a cross section of primary particle of the negative electrode active material.

  • Patent number: 10061720
    Abstract: A storage system includes a controller part, a data storage part, and a transfer path of a signal that couples these parts. A driver included in the controller part transmits the signal including write data on the basis of a configured parameter, a receiver included in the data storage part receives the signal, and the write data included in the signal is written into a first storage area. The controller part reads the write data from the first storage area, determines whether or not a bit error exists in the write data, changes the parameter when the bit error exists to repeat similar determination and find an appropriate parameter at which the bit error no longer exists.
