Abstract: According to the invention, a particulate electrode material is provided, which has high energy density, safety and longevity (stability relative to degradation and material fatigue). Furthermore, the electrode material is distinguished both by high electrical and high ionic conductivity and consequently achieves very low resistance values. Furthermore, a method for coating particulate electrode material is provided according to the invention, with which method the electrode material according to the invention can be produced. Finally, uses of the electrode material according to the invention are demonstrated.

Abstract: The present invention relates to a lithium accumulator or a combination thereof with a double-layer capacitor which is distinguished by a solid material- or gel electrolyte and a binder made of inorganic-organic hybrid polymer. By means of the new binder concept presented here, it is possible to revolutionise the contacting of the individual components in these accumulators and thus to enable a fundamental improvement in the ion transport. Associated therewith is a new, fast, simple and flexible production method for lithium accumulators which optimises these with respect to safety, stability, environmental friendliness and efficiency.

Abstract: The present invention relates to particles, which are suited as electrode material for the negative electrode of a battery functioning according to the principle of nickel-metal hydride batteries. In order to increase the power density of such batteries, it is desirable to use relatively small particles for the electrode material. However, said particles are sensitive to air and frequently highly flammable. The invention therefore proposes to provide said particles with a coating made of an organically modified (hetero) silicic acid polycondensate. In the presence of the KOH electrolyte solution, said coating converts during operation into a gel electrolyte, which not only does not impede the passage of the ions necessary for the activity of the battery, but even facilitates it.
