摘要： This invention concerns a lithium rechargeable electrochemical cell containing electrochemical redox active compounds in the electrolyte. The cell is composed of two compartments, where the cathodic compartment comprises a cathodic lithium insertion material and one or more of p-type redox active compound(s) in the electrolyte; the anodic compartment comprises an anodic lithium insertion material and one or more of n-type redox active compound(s) in the electrolyte. These two compartments are separated by a separator and the redox active compounds are confined only in each compartment. Such a rechargeable electrochemical cell is suitable for high energy density applications. The present invention also concerns the general use of redox active compounds and electrochemically addressable electrode systems containing similar components which are suitable for use in the electrochemical cell.

摘要： This invention concerns a novel method for surface derivatization of electrode materials for Li-ion batteries. The derivatization is based on adsorption of a composite assembly consisting of amphiphilic redox active molecule attached to single walled carbon nanotube (SWCNT). Its role consists in the enhancement of electronic conductivity of electrode materials, such as phosphate olivines, without requesting any significant increase of the electrode volume and mass. The SWCNT is linked to the redox molecule via non-covalent or covalent interaction with the hydrophobic part of the molecule or electrostatic interaction. The hydrophilic part of the molecule serves as the anchoring site for surface modification of the electrode active material. The redox potential of the molecule is close to the redox potential of the electrode active material. The adsorbed assembly of redox-molecule & SWCNT thus improves the charge transfer from a current collector to the electrode active material.

摘要： Novel process for the preparation of finely divided, nano-structured, olivine lithium metal phosphates (LiMPO4) (where metal M is iron, cobalt, manganese, nickel, vanadium, copper, titanium and mix of them) materials have been developed. This so called Polyol” method consists of heating of suited precursor materials in a multivalent, high-boiling point multivalent alcohol like glycols with the general formula HO—(—C2H4O—), —H where n=1-10 or HO—(—C3H6O—)n—H where n=1-10, or other polyols with the general formula HOCH2—(—C3H5OH—)n—H where n=1-10, like for example the tridecane-1,4,7,10,13-pentaol. A novel method for implementing the resulting materials as cathode materials for Li.-ion batteries is also developed.
