    Abstract: A novel content classification method is provided. A content classification method using machine learning for a learning model and a classifier fabrication method are provided. In Step 1, a data set containing a plurality of contents is acquired. Learning labels are attached to m contents, and the learning labels are not attached to the remaining contents. In Step 2, a first learning model is created by machine learning using the m contents. In Step 3, judgment labels are attached to the plurality of contents using the first learning model and are displayed on a GUI. In Step 4, new learning labels are attached to k contents in the plurality of contents. In Step 5, a second learning model is created by the machine learning using the k contents. In Step 6, judgment labels are attached to the plurality of contents using the second learning model and are displayed on the GUI.

    Abstract: An object is to provide a storage battery using materials for an electrode active material without waste. Another object is to provide an electrode active material with an appropriate compounding ratio. A lithium-ion storage battery includes a positive electrode, a negative electrode, and an electrolytic solution therebetween. The positive electrode includes a positive electrode current collector and a positive electrode active material layer. The positive electrode active material layer includes a first positive electrode active material and a second positive electrode active material. The charge capacity of the first positive electrode active material is higher than the discharge capacity thereof. The discharge capacity of the second positive electrode active material is higher than the charge capacity thereof. The first positive electrode active material may be a lithium-manganese composite oxide, and the second positive electrode active material may be a lithium-manganese oxide with a spinel crystal structure.

    Abstract: An object of one embodiment of the present invention is to provide a secondary battery in which deterioration of charge-discharge cycle characteristics is suppressed, to suppress generation of defects caused by expansion and contraction of an active material in a negative electrode, or to prevent deterioration caused by deformation of a secondary battery. To prevent deterioration, a material that can be alloyed with lithium and fluidified easily is used for a negative electrode. To hold a negative electrode active material over a surface of a current collector, a covering layer that covers the negative electrode active material is provided. Furthermore, a portion where the current collector and the negative electrode active material are in contact with each other is alloyed. In other words, an alloy that is in contact with both the current collector and the negative electrode active material is provided in the negative electrode.
