Abstract:
The present disclosure provides a rechargeable electrochemical cell including an electrolyte side, a cathode side, and a polymer/plasticizer. The electrolyte side includes a solid glass electrolyte including an electrolyte mobile cation and electric dipoles, as well as an anode including a metal of the electrolyte mobile cation and contacting the solid glass electrolyte at an anode:solid glass electrolyte interface. The cathode side includes a cathode including a cathode active material into which a cathode guest cation is reversibly extracted/inserted. The cathode active material has a voltage versus lithium (Li) metal of between 3V and 15V. The polymer/plasticizer contacts the solid glass electrolyte at a solid glass electrolyte:polymer/plasticizer interface and the cathode at a polymer/plasticizer:cathode interface such that the cathode guest cation is confined to the cathode side and the electrolyte mobile cation is confined to the anode side during charge and discharge of the electrochemical cell.
Abstract:
The invention relates to materials for use as electrodes in an alkali-ion secondary (rechargeable) battery, particularly a lithium-ion battery. The invention provides transition-metal compounds having the ordered-olivine or the rhombohedral NASICON structure and the polyanion (PO4)3− as at least one constituent for use as electrode material for alkali-ion rechargeable batteries.

Abstract:
The invention provides an electrochemical cell wherein an anode, solid electrolyte and cathode each comprise a cubic-close-packed framework structure having, as its basic structural unit, a unit of the formula (B.sub.2)X.sub.4.sup.n- which is the structural unit of an A(B.sub.2)X.sub.4 spinel. The structure accommodates active cations M.sup.+ capable of diffusion therethrough. The invention also extends to electrodes and electrolytes of the above type for use in such cells.

Fast alkali-metal-ion transporters are provided having low resistivities and low-activation-energy mobilities at temperatures at which alkali metals are molten. The novel compounds promote alkali-metal-ion transport in three dimensions within their crystalline structure and have the general formula:A.sub.n X.sub.2 (ZO.sub.4).sub.3orA.sub.m (Z'.sub.2 O.sub.4)wherein A is potassium, sodium or lithium, Z' is a tetrahedrally coordinated cation or mixtures thereof, X is an octahedrally coordinated cation or mixtures thereof, n is a number greater than 1 and less than 4, m is a number from 1 up to 2 and Z' is a mixture of at least two Z' cations.BACKGROUND OF THE INVENTION
Abstract:
The present invention includes an apparatus and method of making and using a composition that includes the replacement of electrochemically inactive additives with a conductive and electrochemically active polymer that is attached so as to make an electrical contract to the redox couples of the electrochemically active oxide particles into/from which Lithium is reversibly inserted/extracted in a battery discharge/charge cycle.
