Abstract: The present invention relates to methods for producing anode materials for use in nonaqueous electrolyte secondary batteries. In the present invention, a metal-semiconductor alloy layer is formed on an anode material by contacting a portion of the anode material with a solution containing metals ions and a dissolution component. When the anode material is contacted with the solution, the dissolution component dissolves a part of the semiconductor material in the anode material and deposit the metal on the anode material. After deposition, the anode material and metal are annealed to form a uniform metal-semiconductor alloy layer. The anode material of the present invention can be in a monolithic form or a particle form. When the anode material is in a particle form, the particulate anode material can be further shaped and sintered to agglomerate the particulate anode material.

Abstract: Embodiments of secondary batteries having electrode assemblies are provided. A secondary battery can comprise an electrode assembly having a stacked series of layers, the stacked series of layers having an offset between electrode and counter-electrode layers in a unit cell member of the stacked series. A set of constraints can be provided with a primary constraint system with first and second primary growth constraints separated from each other in a longitudinal direction, and connected by at least one primary connecting member, and a secondary constraint system comprises first and second secondary growth constraints separated in a second direction and connected by members of the stacked series of layers. The primary constraint system may at least partially restrain growth of the electrode assembly in the longitudinal direction, and the secondary constraint system may at least partially restrain growth in the second direction that is orthogonal to the longitudinal direction.
