    摘要： The present application provides an electrode and a lithium-ion battery. The electrode comprises: a current collector; a first active material layer comprising a first active material; and a second active material layer comprising a second active material; wherein the first active material layer is arranged between the current collector and the second active material layer. The first active material layer is formed on at least one surface of the current collector, and a ratio of an average particle size of the second active material to an average particle size of the first active material is from 1:1 to 40:1. The active material layer is used in the present application to ensure that the lithium-ion battery does not generate a short circuit when pressed by an external force, thereby ensuring the mechanical safety performance of the lithium-ion battery.

    摘要： An energy storage device, such as a silver oxide battery, can include a silver-containing cathode and an electrolyte having an ionic liquid. An anion of the ionic liquid is selected from the group consisting of: methanesulfonate, methylsulfate, acetate, and fluoroacetate. A cation of the ionic liquid can be selected from the group consisting of: imidazolium, pyridinium, ammonium, piperidinium, pyrrolidinium, sulfonium, and phosphonium. The energy storage device may include a printed or non-printed separator. The printed separator can include a gel including dissolved cellulose powder and the electrolyte. The non-printed separator can include a gel including at least partially dissolved regenerate cellulose and the electrolyte. An energy storage device fabrication process can include applying a plasma treatment to a surface of each of a cathode, anode, separator, and current collectors. The plasma treatment process can improve wettability, adhesion, electron and/or ionic transport across the treated surface.

    摘要： The present invention provides a battery electrode comprising an active battery material enclosed in the pores of a conductive nanoporous scaffold. The pores in the scaffold constrain the dimensions for the active battery material and inhibit sintering, which results in better cycling stability, longer battery lifetime, and greater power through less agglomeration. Additionally, the scaffold forms electrically conducting pathways to the active battery nanoparticles that are dispersed. In some variations, a battery electrode of the invention includes an electrically conductive scaffold material with pores having at least one length dimension selected from about 0.5 nm to about 100 nm, and an oxide material contained within the pores, wherein the oxide material is electrochemically active.

    摘要： An improved battery separator and an energy cell comprising the improved battery separator are provided. The improved battery separator comprises a porous membrane having at least one of the following properties when wet with electrolyte: has no or low volume; has no or low mass; soaks as much liquid electrolyte as possible; blocks or removes any harmful substances in the electrolyte; never melts at any high temperature; does not react with the cathode or the anode under any conditions; has a mechanical strength equal to or greater than steel; is an electronic insulator under any conditions; and blocks metal dendrite growth.

    摘要： Using the generally used coating method of an active material paste to a metal foil on a 3DF made the electrode properties instable due to residual air inside of the 3DF, and had the risk of causing micro short circuit of the battery due to metal fine powder and the like adhered to the 3DF and the 3DF exposed to the electrode surface. To solve the above-mentioned, the coating of the active material paste to the 3DF was made into a two-step coating process as shown below. Step one removes the air and fills the paste at the same time by applying the paste flow from one side of the 3DF (the first step coating process). Step two coats a new paste onto the surface of the electrode obtained by step one (the second step coating process). This electrode obtained by the two-step coating process hardly has remaining air amount, can uniformly confine metallic power dust or the 3DF itself inside the electrode (the first step coating process), and in addition to this, has the capability of Li ions freely moving between the electrode surface and the depth portion of the electrode through the opening portion formed on the tip portion of the innumerable protrusions of the 3DF, the micro short circuit of the battery due to Li dendrite was prevented even in repeated charge and discharge.
