A layered textile energy storage device can include first and second encasing layers, an anode, a cathode, and a flexible separator layer. The first and second encasing layers can each include a nylon fabric coated with a polyurethane. The anode can include a carbon fabric coated with anode active material, carbon nanotubes, and a binder material. The cathode can include a carbon fabric coated with cathode active material, carbon nanotubes, and a binder material. The flexible separator layer can be disposed between the anode and cathode to prevent internal shorting of the layered textile energy storage device. The anode, the cathode and the flexible separator layer can be disposed between the first and the second encasing layers.

Gel polymer electrolyte compositions including a cross-linked three-dimensional polymer network and an electrolyte composition comprising an electrolyte and water are disclosed. The gel polymer electrolyte compositions can be included in an aqueous electrochemical cell, in which a gel polymer electrolyte can be positioned between an anode and a cathode. Methods of forming a gel polymer electrolyte in the form of a film, and methods of forming an aqueous electrochemical cell including a gel polymer electrolyte, are also disclosed.

Electrochemical cells and electrolytes contained therein

A gel polymer electrolyte (GPE) composition and a method of forming the same are provided. The GPE includes a polymer network and an electrolyte composition comprising a deep eutectic solvent (DES) having a eutectic point of less than or equal to 25&#xb0; C. An electrochemical cell including a GPE and a method of forming the same are also provided.

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.
