Abstract: Powders, electrodes, zinc-air batteries and corresponding methods are provided. Powders comprise perforated shells having a size of at least 100 nm and comprising openings smaller than 10 nm. The shells are electrically conductive and/or comprise an electrically conductive coating. Powders further comprise zinc and/or zinc oxide which resides at least partially within the shells. Methods comprise wetting the shells with a zinc solution to yield at least partial penetration of the zinc solution through the openings, and coating zinc internally in the shells by application of electric current to the shells. Upon electrode preparation from the powder, cell construction and cell operation, zinc is oxidized to provide energy and the shells retain formed Zn O therewith, providing sufficient volume for the associated expansion and maintaining thereby the mechanical stability and structure of the electrode—to enable many operation cycles of the rechargeable zinc-air batteries.

Abstract: A sintered material excellent in thermal stress and bonding strength; a connection structure containing the sintered material; a composition for bonding with which the sintered material can be produced; and a method for producing the sintered material. The sintered material has a base portion, buffer portions, and filling portions. The buffer portions and filling portions are dispersed in the base portion. The base portion is a metal sintered body, each buffer portion is formed from a pore and/or material that is not the same as the sintered body, and each filling portion is formed from particles and/or fibers. The sintered material satisfies A>B. A is the kurtosis of volume distribution of the base portions in a three-dimensional image of the sintered material. B is the kurtosis of volume distribution of the base portions in a three-dimensional image of the sintered material from which the filling portions are removed.
