Abstract: A method for preparing an amorphous carbon material for use as an electrode, such as the anode of an electrochemical cell. The amorphous carbon is fabricated in a one heating step process from multi-functional organic monomers. The material is then reheated in the presence of a lithium salt such as LiNO3, Li3PO4 or LiOH. Electrodes so fabricated may be incorporated into electrochemical cells (10) as the anode (20) thereof.

Abstract: An electrode material for a lithium rechargeable cell (10) in which the negative electrode (30) is fabricated of a combination of first and second carbon materials. The first carbon material is a substantially amorphous carbon material which is preferably the pyrolytic decomposition product of a lignin precursor material. The second carbon material used in the negative electrode material is preferably also a carbon material, though one characterized by a greater density than the amorphous carbon. In this regard, the second carbon material is preferably a graphite carbon material. The presence of graphite in the overall electrode composition increases electro density, acts as a binder in the compression on the electrode materials onto a current carrying substrate and as a lubricant in the fabrication process.

Abstract: A thin film multi-layered electrolyte (56) for a rechargeable electrochemical cell (50), and a rechargeable cell including the electrolyte. The multi-layered electrolyte (56) consists of a primary electrolyte (58) having at least one secondary electrolyte material (60a) disposed on one surface thereof. The secondary electrolyte material (60a) should be selected so as to have a potential stability window sufficient to prevent decomposition of the primary electrolyte, while preventing chemical reactions leading to the formation of ionically non-conducting materials on the surface of the electrodes of the electrochemical cell. A rechargeable electrochemical cell is made by disposing the multi-layered material between a positive (54) and negative (52) electrode.

Abstract: An electrode for rechargeable electrochemical cells and a rechargeable electrochemical cell made from the electrode. The electrode consists of a matrix material (40) made of one or more conductive polymers, and a reactant material (30) finely dispersed in the matrix material. A rechargeable electrochemincal cell is made by using the electrode. The negative electrode is a reactant material (30) finely dispersed in one or more conductive polymers (40). Both the electrode and the electrochemical cell may contain an electroactive species to facilitate the charge transfer between the electrodes. The electrolyte can be a solid-state material. A polymeric material serves as the matrix material in the preferred embodiment. Because of the rubbery nature of the material, it may also act as the binding component (50). It also acts as the current collector (60) where electrons are transferred from the point of the electrochemical reaction to the current collector leads.
