For example, the self-standing electrodes may be used in lithium-ion batteries (LIBs). Particularly, the self-standing electrodes comprise a first electronically conductive material serving as a current collector, the surface of the first electronically conductive material being grafted with a hydrophilic group, a binder comprising cellulose fibres, an electrochemically active material, and optionally a second electronically conductive material. A process for the preparation of the self-standing electrodes is also described.

摘要： Disclosed is a carbon felt impregnated with inorganic particles. The impregnated carbon felt can be used together with sulfur in a cathode of a sodium-sulfur (Na—S) battery. Also disclosed is a method for producing the impregnated carbon felt. According to exemplary embodiments, the problem of the prior art can be solved in which inorganic particles such as alumina particles are not directly adhered to carbon felts, thus necessitating complicated processes. In addition, a slurry including an inorganic binder and alumina particles can be used to directly coat the alumina particles on the surface of a carbon felt, making the production procedure very simple. Furthermore, the use of the carbon felt surface coated with the alumina particles in a Na—S battery increases the wicking of sodium polysulfides, suppresses the accumulation of sulfur as an insulator on the surface of beta-alumina as an electrolyte, and inhibits non-uniform aggregation of sulfur or sodium polysulfides on the carbon felt, so that the concentration polarization of charges can be reduced without a significant increase in the internal resistance of the battery, achieving high utilization efficiency of sulfur as a reactant.

摘要： Embodiments of the invention provide a lead-acid battery having a positive electrode, a negative electrode, and a separator positioned between the electrodes to electrically insulate the electrodes. Battery includes a nonwoven fiber mat positioned adjacent an electrode. Mat includes a mixture of first glass fibers having diameters between 8 μm to 13 μm and second glass fibers having diameters of at least 6 μm and a silane sizing. An acid resistant binder bonds the glass fibers to form mat. A wetting component is applied to increase the wettability such that mat exhibits an average water wick height of at least 1.0 cm after exposure to water for 10 minutes. A conductive material is disposed on a surface of mat such that when mat is adjacent an electrode, the conductive material contacts the electrode. An electrical resistance of less than 100,000 ohms per square enables electron flow about mat.
