An electrode for a battery cell, including an active material which contains silicon and which contains a first polymer which is ionically conductive. The active material contains in this case a copolymer, which includes the first polymer and a second polymer, the second polymer being electrically conductive. A battery cell which includes at least one electrode is also described.

An aqueous electrolyte for a capacitor contains at least one transition metal complex. An aqueous electrolyte containing at least one transition metal complex can be used in a supercapacitor, in a pseudocapacitor, or in a hybrid supercapacitor. A hybrid supercapacitor contains an aqueous electrolyte, which contains at least one transition metal complex.

Aqueous electrolyte, use of the electrolyte and hybrid supercapacitor containing the electrolyte

A hybrid supercapacitor has two electrodes, one of which functions as a cathode, and the other as an anode. The hybrid supercapacitor further includes an electrolyte arranged between the cathode and the anode. The electrolyte contains a solvent selected from the group consisting of methanol, 1-propanol, 1-heptanol, ethyl acetoacetate, ethylene glycol, diethylene glycol, glycerol, benzyl alcohol, di-n-butyl phthalate and mixtures thereof.

Hybrid supercapacitor

A method is described for producing silicon particles, in particular for an anode material of a lithium cell. In order to improve the cycle stability of lithium cells and to minimize losses in capacitance, in particular, microorganisms are dispersed in at least one solvent in a method step a), the solvent including at least one silicon compound. In a method step b), the at least one solvent is then removed, and a residue remains. In method step c), the residue is then heated under a reducing atmosphere. In addition, the invention relates to corresponding silicon particles, and to a corresponding anode material including silicon particles, and to a lithium cell provided with such.

A symmetric hybrid supercapacitor has two internally hybridized electrodes having both faradic and capacitatively active materials. More specifically, the symmetric hybrid supercapacitor has a cathode and an anode. The cathode contains LiMnFePO. The LiMnFePOis used as electrode material for the hybrid supercapacitor. The condition applies that 0.1&#x3c;x&#x3c;0.9.

A silicon-carbon composite. In order to improve the cycle stability of a lithium cell equipped therewith, the silicon-carbon composite is produced by a condensation reaction of silicon particles surface-modified with a first condensation-capable group and carbon particles surface-modified with a second condensation-capable group, the silicon particles being covalently bonded to the carbon particles via the condensation reaction product of the first condensation-capable group and the second condensation-capable group. In addition, a method for the production thereof and to an electrode, an electrode material, and a lithium cell is described.
