The present disclosure discloses a porous metal matrix composite (MMC), wherein the porous MMC includes a metal material, a spacing material forming an interconnected structure and embedded in the metal material to form an interface between the metal material and the interconnected structure; and a first plurality of pores located at the interface.

A battery grid is disclosed. The battery grid includes a pattern of grid wires. The pattern includes a grid wire having a first segment with a first corrosion resistance and a second segment with a second corrosion resistance which is less than the first corrosion resistance. The second segment corrodes at a rate which is faster than the corrosion rate of the first segment so as to dynamically release internal stress and control grid growth of the battery grid during its service life. A battery includes said grid and a method of forming said grid are also disclosed.
