Abstract: An information transmission apparatus can use a salesclerk information storage unit. The salesclerk information storage unit stores, by a plurality of salesclerks, salesclerk identification information about the salesclerk and detailed information about the salesclerk in association with each other. Then, the information transmission apparatus includes a salesclerk position transmission unit and a detailed information transmission unit. The salesclerk position transmission unit transmits, for each of a plurality of salesclerks present in a store, salesclerk position information about the salesclerk and salesclerk identification information about the salesclerk in association with each other to a customer terminal.

Abstract: A lithium-ion rechargeable battery includes a negative electrode plate including a negative electrode substrate and a negative electrode mixture layer applied to the substrate, a positive electrode plate including a positive electrode substrate and a positive electrode mixture layer applied to the substrate, a separator arranged between the negative electrode plate and the positive electrode plate, and a non-aqueous electrolyte. The negative electrode substrate includes a negative electrode connection portion that projects from the negative electrode mixture layer in a first width direction. The positive electrode substrate includes a positive electrode connection portion that projects from the positive electrode mixture layer in a second width direction. The separator has a gas permeability that is greater at a portion facing an end of the positive electrode mixture layer in the second width direction than a portion facing an end of the positive electrode mixture layer in the first width direction.
