  • Patent number: 11108033
    Abstract: The present invention relates to an electrochemical cell (10) comprising a negative electrode (11) comprising alkali metal or alkaline earth metal (e.g. lithium), a positive electrode (12), and an electrolytic solution (13) between the negative electrode (11) and positive electrode (12). A salt (e.g. LiPF6) comprising ions of the corresponding alkali metal or alkaline earth metal of the negative electrode is dissolved in the electrolytic solution (13) with a molarity lower than 0.25M, and at least one supporting salt (e.g. TBAPF6) is dissolved in the electrolytic solution to improve the conductivity of the electrolytic solution. In addition, the electrochemical cell is configured to receive at least one electrical nucleation pulse (20; 40) having a pulse length (lp) prior to applying an electrical deposition current (21; 41) for charging of the electrochemical cell (10).

  • Patent number: 9389226
    Abstract: There is disclosed a method for partially derivatizing a curved surface of particles in an electrically conducting solvent, said method comprises the steps: a) bringing particles in close contact with at least one surface by using a force, b) inducing a chemical reaction on at least one part of a particle by applying an electrical potential between said at least one surface and the electrically conducting solvent, and c) further reacting said at least one part of a particle where a chemical reaction has been induced in step b) above. There is further disclosed a partially derivatized particle as well as uses of the particle. Advantages include that the method is simple and only requires a potentiostat in addition to standard laboratory equipment, is inexpensive, time-efficient, and inherently parallel.

  • Patent number: 8920971
    Abstract: A composite material in the form of a continuous structure comprises an intrinsically conducting polymer (ICP) layer coated on a substrate, the composite material having a surface area of at least 0.1 m2/g, at least 1 m2/g, or at least 5 m2/g. Methods of manufacturing the composite material comprise coating the substrate with a layer of the intrinsically conducting polymer. Electrochemical or electrical devices comprise at least one component formed of the composite material.

  • Patent number: 8679807
    Abstract: There is provided a method for covalent immobilization of at least one molecule comprising at least one amino group, said method comprising the sequential steps of: a) providing a surface comprising —SH groups, b) oxidizing the surface comprising —SH groups using redox reactions in the presence of noble metal ions, and c) contacting the surface with at least one molecule comprising at least one amino group to obtain a covalent binding of the at least one molecule to the surface, wherein said at least one amino group is involved in obtaining said covalent bond. The immobilized molecules are immobilized via stable covalent bonds. The method is more versatile since it can be performed as a one step method. All reaction steps are performed in aqueous solution. All steps can be performed at room temperature. The chemicals used are less expensive and less toxic compared to the prior art.
