Abstract: Embodiments described herein relate generally to apparatuses and processes for forming semi-solid electrodes having high active solids loading by removing excess electrolyte. In some embodiments, the semi-solid electrode material can be formed by mixing an active material and, optionally, a conductive material in a liquid electrolyte to form a suspension. In some embodiments, the semi-solid electrode material can be disposed onto a current collector to form an intermediate electrode. In some embodiments, the semi-solid electrode material can have a first composition in which the ratio of electrolyte to active material is between about 10:1 and about 1:1. In some embodiments, a method for converting the semi-solid electrode material from the first composition into the second composition includes removing a portion of the electrolyte from the semi-solid electrode material.

Abstract: Iron electrode materials, iron electrodes, and methods for fabricating said iron electrode materials and iron electrodes via elevated temperature thermomechanical processing of porous particulate iron materials are described. For example, as part of iron electrode manufacture, a particulate iron material into an apparatus may be provided.

Abstract: The present disclosure relates to a method of electrodeposition using pulsed currents to improve the uniformity of electrodeposited materials at solid-solid interfaces. It has been demonstrated that films of electrodeposited metals can be robustly deposited at a solid-solid interface without damage to the solid-electrolyte. Furthermore, the effects of the pulse parameters, including current density, pulse width, and duty cycle have shown to have dramatic effects on the spatial distribution of the electrodeposited metal. This methodology can aid in the manufacturing of thin films and microscopic structures for application in advanced functional materials and electrochemical devices. In one embodiment, the method provides for anode-free manufacturing in which a battery is fabricated in the discharged state, with a bare current collector replacing the conventional anode, and a metal anode is then formed electrochemically on the first charge cycle by electroplating a metal contained within the cathode.
