摘要： Solid battery components are provided. A block copolymeric electrolyte is non-cross-linked 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 My, Nz portion of the compound is (4-x). In certain embodiments, these compounds are used in the cathodes of rechargeable batteries. The present invention also includes methods of predicting the potential utility of metal dichalcogenide compounds for use in lithium intercalation compounds. It also provides methods for processing lithium intercalation oxides with the structure and compositional homogeneity necessary to realize the increased formation energies of said compounds. An article is made of a dimensionally-stable, interpenetrating microstructure of a first phase including a first component and a second phase, immiscible with the first phase, including a second component. The first and second phases define interphase boundaries between the, and at least one particle is positioned between a first phase and a second phase at an interphase boundary. When the first and second phases are electronically-conductive and ionically-conductive polymers, respectively, and the particles are ion host particles, the arrangement is an electrode of a battery.

摘要： An electrochemical battery that exchanges energy with an external device. The battery includes a container (22) having walls and containing a positive electrode (16), a negative electrode (14) and an intervening electrolyte (20), the electrodes and electrolyte existing as liquid material layers in a vertical stack within the container walls at the operating temperature of the battery. One of the positive electrode (16) and the negative electrode (14) is disposed over the electrolyte. A lid (26) closes a top of the container (22); a positive current collector (23) is in electrical contact with the positive electrode (16); and a negative current collector (27) is in electrical contact with the negative electrode (14). Positive and negative current collectors (23, 27) are adapted for connection to the external device to create a circuit through which current flows. The current collector is in contact with the one electrode is suspended from the lid (26) and comprises a structure (62) configured to hold one of the electrodes away from the walls of the container.

摘要： In general, the invention relates to electrode materials, e.g., novel cathode materials with high density, low cost, and high safety. A voltage design strategy based on the mixing of different transition metals in crystal structures known to be able to accommodate lithium in insertion and delithiation is presented herein. By mixing a metal active on the +2/+3 couple (e.g., Fe) with an element active on the +3/+5 or +3/+6 couples (e.g., V or Mo), high capacity multi-electron cathodes are designed in an ad-equate voltage window.

摘要： 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.
