Abstract: The composite active material according to one aspect of the present disclosure includes an active material including Li, Ti, and O and a first solid electrolyte. The active material is a porous material having a plurality of pores. The first solid electrolyte includes Li, M, and X. M is at least one selected from the group consisting of metal elements and metalloid elements belonging to the 5th or 6th period. X is at least one selected from the group consisting of F, Cl, Br, and I. At least a part of the first solid electrolyte is present inside the plurality of pores.

Abstract: The invention can firmly fix both ends of a carcass ply while maintaining a weight saving and an effect of inhibiting a bead damage high. A pneumatic tire is provided with a bead core (5) constituted by core separated pieces (20U, 20L) separated into upper and lower sides in a radial direction, a bead apex rubber (8) extending from an upper surface thereof to an upper side in the radial direction, and a carcass ply (6A) having a ply lock portion (11) locked to the bead core (5).

Abstract: A pneumatic tire including a carcass containing a ply of cords defining the innermost reinforcing cord layer extending between bead portions, and an airtight layer disposed inside the cords of the carcass ply along the inner surface of the tire, covering substantially the entire inner surface of the tire, wherein the airtight layer is made of air-impermeable rubber including at least 10 weight % of halogenated butyl rubber and/or halogenated isobutylene-paramethyl styrene copolymer in its rubber base, and the thickness of the airtight layer measured from the inner surface of the tire to the cords of the carcass ply is in a range of from 0.2 to 0.7 mm.

Abstract: A pneumatic tire comprises the following belt (A) or belt (B). The belt (A) comprises a ply made of waved monofilament steel cords and a ply made of multi-filament steel cords, wherein the waved monofilament steel cord is (1) spirally waved so that the wave pitches PA are in a range of from 14 to 50 mm and the amplitude HA of each wave is in a range of from 0.002 to 0.02 times the pitch PA of the wave, or (2) two-dimensionally waved so that the wave pitches PB are in a range of from 5 to 50 mm, and the amplitude HB of each wave is in a range of from 0.002 to 0.05 times the pitch PB of the wave. The belt (B) comprises two plies made of waved monofilament steel cords, wherein the waved monofilament steel cord is waved so that the wave pitches P are in a range of from 0.008 to 0.08 times the circumference of the tire and the wave height of each wave is in a range of from 0.002 to 0.025 times the pitch P of the wave.
