Abstract: The mechanical strength of an electrode sheet becomes problematic when employing means for improving the productivity of an electrode process. In a collector aluminum foil of the present invention, when the intensities of the (022) and (111) diffraction peaks appearing in an XRD spectrum measured in the reflection geometry are denoted by IB(022) and IB(111), respectively, a value of IB(022)/IB(111) is 200 or less.

Abstract: There is provided a negative electrode material for lithium ion secondary batteries having a structure in which in charged and discharged states, a LixSi compound (2) exists in the inside of a Li oxide (1) and the LixSi compound is dispersed in the inside of the Li oxide. The negative electrode material, in which volume change resulting from charge/discharge is suppressed, has excellent performance as a negative electrode material for lithium ion secondary batteries.

Abstract: The optimization device includes an annealing means. The annealing means executes solution calculation so as to exclude from search range spin sets whose distances from the spin sets indicating optimal solutions obtained by the n−1st solution calculation are within a predetermined range in the nth solution calculation.

Abstract: There is provided an optimization apparatus that reduces the time required to create a delivery plan. An optimization apparatus (100) includes an acquisition unit (110) that acquires delivery information regarding each of one or more products for each of a plurality of consumption locations, an identification unit (120) that identifies a plurality of delivery task candidates departing from a delivery source, delivering the one or more products to each of one or more consumption locations, and returning to the delivery source, a determination unit (130) that determines, based on the delivery information, at least one of evaluation values and a vehicle type of a delivery vehicle for each candidate, and a selection unit (140) that selects a plurality of delivery tasks from the plurality of identified candidates based on a result of optimizing an objective function based on a determination result.
