Abstract: Triethylboron is a useful precursor for depositing films in an atomic layer deposition process. This precursor is useful for depositing boron containing films. Boron containing films are excellent lubricating coatings for zinc powders, improving their flow properties and simplifying powder handling. This makes the coated zinc powders especially useful for battery applications in which a zinc powder is used as an anode material.

Abstract: Thin-film electrodes and battery cells, and methods of fabrication. A thin film electrode may be fabricated from a non-metallic, non-conductive porous support structure having pores with micrometer-range diameters. The support may include a polymer film. A first surface of the support is metalized, and the pores are partially metallized to create metal tubes having a thickness within a range of 50 to 150 nanometers, in contact with the metal layer. An active material is disposed within metalized portions of the pores. An electrolyte is disposed within non-metalized portions of the pores. Active materials may be selected to create an anode and a cathode. Non-metalized surfaces of the anode and cathode may be contacted to one another to form a battery cell, with the non-metalized electrolyte-containing portions of the anode facing the electrolyte-containing portions of the cathode pores. A battery cell may be fabricated as, for example, a nickel-zinc battery cell.

Abstract: Provided are examples of electrochemically active electrode materials, electrodes using such materials, and methods of manufacturing such electrodes. Electrochemically active electrode materials may include a high surface area template containing a metal silicide and a layer of high capacity active material deposited over the template. The template may serve as a mechanical support for the active material and/or an electrical conductor between the active material and, for example, a substrate. Due to the high surface area of the template, even a thin layer of the active material can provide sufficient active material loading and corresponding battery capacity. As such, a thickness of the layer may be maintained below the fracture threshold of the active material used and preserve its structural integrity during battery cycling.
