Abstract:
An all-solid-state lithium-ion secondary battery includes a cathode active material, an anode active material, a solid electrolyte between the cathode and anode active materials, and an intermediate layer between the solid electrolyte and the cathode active material. The cathode and anode active materials are able to store and release a lithium ion. The solid electrolyte has lithium ion conductivity. The intermediate layer is constituted of elements including all elements constituting the cathode active material. A lithium ion in the intermediate layer is less ionic than that in the cathode active material.

Abstract:
An information processing system includes: an information processing apparatus that transmits information pertaining to a relational expression representing energy of a structure of an aggregate of atoms; and an optimization apparatus, which is an example of a computing apparatus that performs computation using the relational expression. The relational expression is acquired on the basis of atomic information and position information, and includes two or more variables that indicate the states of atoms located at two or more positions in the aggregate. The information processing apparatus includes: a first communicator that transmits the information pertaining to the relational expression to the optimization apparatus, and receives, from the optimization apparatus, values of the two or more variables derived by performing the above computation; and an outputter that outputs structure information corresponding to the values of the two or more variables.
