Abstract: The invention relates to a process for producing metal-coated inorganic particles by means of currentless deposition technique in which the inorganic particles are first functionalized, then introduced into an aqueous metal-salt solution containing metal ions, and the metal is reduced by adding a reducing agent to the aqueous metal-salt mixture containing the functionalized particles and the metal is deposited on the functionalized particles, wherein the functionalization of the inorganic particles takes place by means of aminophosphonic acids, aminocarboxylic acids and/or aminoalcohol phosphoric acid esters, and the aminophosphonic acid, the aminocarboxylic acid and/or the aminoalcohol phosphoric acid ester form(s) a monolayer on the surface of the inorganic particles. The metal-coated inorganic particles can be introduced into metal matrices due to their improved surface properties.

Abstract: The invention relates to alkaline secondary batteries. The secondary battery contains a cathode, an anode and an electrolyte, said secondary battery being arranged between the cathode and anode and comprises an alkali metal ion conductive contact to the cathode and to the carbon layer of the anode. The anode contains or consists of a carbon layer, whereby the carbon layer, alone or in combination with an electrically conductive substrate, forms with an electrically conductive contact.

Abstract: The invention relates to a method for solvent-free production of an electrode. By means of the method it is possible to produce an electrode which has high mechanical stability and which provides a high specific capacitance. The method also enables the production of an electrode which can be used as an anode in a lithium-ion battery, without giving rise to unstable operation with undesirable and irreversible degradation reactions. An electrode is also provided, which has the above-mentioned advantages. In addition, uses of the electrode according to the invention are proposed.
