  • Patent number: 8268471
    Abstract: An electrochemical method and apparatus for high-amperage electrical energy storage features a high-temperature, all-liquid chemistry. The reaction products created during charging remain part of the electrodes during storage for discharge on demand. In a simultaneous ambipolar electrodeposition cell, a reaction compound is electrolyzed to effect transfer from an external power source; the electrode elements are electrodissolved during discharge.

  • Publication number: 20120037844
    Abstract: This invention relates generally to electrode materials, electrochemical cells employing such materials, and methods of synthesizing such materials. The electrode materials have a crystal structure with a high ratio of Li to metal M, which is found to improve capacity by enabling the transfer of a greater amount of lithium per metal, and which is also found to improve stability by retaining a sufficient amount of lithium after charging. Furthermore, synthesis techniques are presented which result in improved charge and discharge capacities and reduced particle sizes of the electrode materials.

  • Publication number: 20110014505
    Abstract: An electrochemical battery that exchanges energy with an external device. The battery includes a container containing a positive electrode, a negative electrode and an intervening electrolyte, the electrodes and electrolyte existing as liquid material layers in the container at the operating temperature of the battery so that adjacent layers form respective electrode-electrolyte interfaces. Positive and negative current collectors are in electrical contact with the positive and negative electrodes, respectively, both collectors being adapted for connection to the external device to create a circuit through which current flows. A circulation producer in the battery causes circulation within at least one of the layers to increase the flux of material in one layer to an interface with an adjacent layer, thereby giving the battery a greater current/power capability.

  • Publication number: 20100264381
    Abstract: The present invention generally relates to certain oxide materials having relatively high energy and/or power densities. Various aspects of the invention are directed to oxide materials having a structure Bi(MjYk)O2, for example, a structure Lij(NijYk)O2 such as Li(Nio.5Mn0.5)02. In this structure, Y represents one or more atoms, each independently selected from the group consisting of alkaline earth metals, transition metals, Group 14 elements, Group 15, or Group 16 elements. In some cases, Y may have a combined valency of at least about 4. In some embodiments, such an oxide material may have an 03 crystal structure, and/or a layered structure such that the oxide comprises a plurality of first, repeating atomic planes comprising Li, and a plurality of second, repeating atomic planes comprising while another set of atomic planes comprises Ni and/or Y.

  • Publication number: 20100163790
    Abstract: The present invention generally relates to unique coatings for use with energy storage particles, such as lithium oxide energy storage materials. The invention provides unique coatings for particles, unique particle/coating combinations, and unique methods for making coatings and/or coated particles. In one aspect of the invention, a particle is formed having a core and a coating. The particle may comprise a core having a material such as LiFePO4, and a coating. The particle may be formed, in some embodiments, by using a non-stoichiometric combination of salts or other precursors, and sintering the same to form particles. LiFePO4 may form as the core of the particle, while the remaining materials may form a coating around the LiFePO4. Typically, the LiFePO4 is crystalline while the coating is generally amorphous, and in some instances, the coating may prevent large crystals of LiFePO4 from forming.

  • Patent number: 7292958
    Abstract: Systems and methods for predicting features of materials of interest. Reference data are analyzed to deduce relationships between the input data sets and output data sets. Reference data includes measured values and/or computed values. The deduced relationships can be specified as equations, correspondences, and/or algorithmic processes that produce appropriate output data when suitable input data is used. In some instances, the output data set is a subset of the input data set, and computational results may be refined by optionally iterating the computational procedure. To deduce features of a new material of interest, a computed or measured input property of the material is provided to an equation, correspondence, or algorithmic procedure previously deduced, and an output is obtained. In some instances, the output is iteratively refined. In some instances, new features deduced for the material of interest are added to a database of input and output data for known materials.

  • Patent number: 7026071
    Abstract: Solid battery components are provided. A block copolymeric electrolyte is non-crosslinked and non-glassy through the entire range of typical battery service temperatures, that is, through the entire range of at least from about 0° C. to about 70° C. The chains of which the copolymer is made each include at least one ionically-conductive block and at least one second block immiscible with the ionically-conductive block. The chains form an amorphous association and are arranged in an ordered nanostructure including a continuous matrix of amorphous ionically-conductive domains and amorphous second domains that are immiscible with the ionically-conductive domains. A compound is provided that has a formula of LixMyNzO2. M and N are each metal atoms or a main group elements, and x, y and z are each numbers from about 0 to about 1. y and z are chosen such that a formal charge on the MyNz portion of the compound is (4-x). In certain embodiments, these compounds are used in the cathodes of rechargeable batteries.
