  • Publication number: 20200251744
    Abstract: A non-aqueous electrolyte secondary battery includes a positive electrode, a negative electrode, and a separator disposed between the positive electrode and the negative electrode. The separator has a multilayer structure in which a first filler layer containing phosphate particles, a porous resin substrate, and a second filler layer containing inorganic particles having higher heat resistance than the phosphate particles are stacked in this order from the negative electrode side. The first filler layer is disposed on the porous resin substrate in such a manner that the surface of the first filler layer faces the surface of the negative electrode. The phosphate particles have a BET specific surface area in the range of 5 m2/g or more and 100 m2/g or less.

  • Patent number: 10685579
    Abstract: A learning system includes an output unit that outputs a first problem and a display message prompting a user to take a break, an acquisition unit that acquires an answer to the first problem from the user, an electroencephalogram measurement unit that measures an electroencephalogram of the user, and a control unit. The control unit determines whether first motivation is present on the basis of a first event-related potential included in the electroencephalogram and starting from a timing at which the first problem is output, determines whether second motivation of the user is present on the basis of a second event-related potential included in the electroencephalogram and starting from a timing at which the answer is acquired, and instructs the output unit to output a display message prompting the user to take a break if the first motivation is not present and the second motivations is not present.
