A surface treatment formulation configured to inhibit scaling or climbing of a surface is provided. The surface treatment formulation may include a base binding material configured to adhere to the surface and a filler material embedded in the base binding material. The filler material may include a dry lubricant having a layered lamellar structure or low inter filler interaction. Furthermore, the surface treatment formulation may be configured to be activated in order to expose the filler material thereby causing formation of a slippery surface to inhibit the scaling or climbing of the surface.

Surface treatment formulation for inhibiting scaling or climbing of a surface

A method of preparing a high capacity nanocomposite cathode of FeFin carbon pores may include preparing a nanoporous carbon precursor, employing electrochemistry or solution chemistry deposition to deposit Fe particles in the carbon pores, reacting nano Fe with liquid hydrofluoric acid to form nano FeFin carbon, and milling to achieve a desired particle size.

High energy density Li-ion battery electrode materials and cells

A thin film electrode is 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.
