Publication number: 20120100428Abstract: 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.Type: ApplicationFiled: June 29, 2010Publication date: April 26, 2012Applicant: Fraunhofer-Gesellschaft zur Foederung der angewand ten Forschung e.V.Inventors: Michael Popall, Birke-Elisabeth Olsowski, Sebastien Cochet
