This invention described the preparation of a series of compounds that can be used as co-solvents, solutes or additives in non-aqueous electrolytes and their test results in various electrochemical devices. The inclusion of these novel compounds in electrolyte systems can enable rechargeable chemistries at high voltages that are otherwise impossible with state-of-the-art electrolyte technologies. These compounds are so chosen because of their beneficial effect on the interphasial chemistries formed at high potentials, such as 5.0 V class cathodes for new Li ion chemistries. The potential application of these compounds goes beyond Li ion battery technology and covers any electrochemical device that employs non-aqueous electrolytes for the benefit of high energy density resultant from high operating voltages.

High capacity battery electrode structures

Номер: US20120070741A1
Автор: Ghyrn E. Loveness, Song Han, Zuqin Liu
Принадлежит: Amprius Inc

Provided are battery electrode structures that maintain high mass loadings (i.e., large amounts per unit area) of high capacity active materials in the electrodes without deteriorating their cycling performance. These mass loading levels correspond to capacities per electrode unit area that are suitable for commercial electrodes even though the active materials are kept thin and generally below their fracture limits. A battery electrode structure may include multiple template layers. An initial template layer may include nanostructures attached to a substrate and have a controlled density. This initial layer may be formed using a controlled thickness source material layer provided, for example, on a substantially inert substrate. Additional one or more template layers are then formed over the initial layer resulting in a multilayer template structure with specific characteristics, such as a surface area, thickness, and porosity. The multilayer template structure is then coated with a high capacity active material.

Disclosed is a technology in which a nozzle part is mounted in a vacuum chamber and a silicon substrate is held to face a discharge hole of the nozzle part. For example, ClF 3 gas and Ar gas are supplied from the nozzle part and the mixed gas is discharged from the nozzle part under a vacuum atmosphere. By doing this, the mixed gas is adiabatically expanded and the Ar atoms or ClF 3 molecules are combined, which become a gas cluster. The gas cluster is irradiated to the surface of the silicon substrate without being ionized and, as a result, the surface of the silicon surface becomes a porous state. Then, lithium is grown on the surface of the silicon substrate in a separate vacuum chamber 41 by sputtering without breaking the vacuum.

A modular frame includes a first row of cell slots configured to receive first prismatic cells of a battery pack system. A second row of cell slots is configured to receive second prismatic cells of the battery pack system. A central interface beam is disposed between the first row of cell slots and the second row of cell slots. The central interface beam includes a first side and a second side. The first side is configured to receive terminals of the first prismatic cells. The second side opposes the first side and is configured to receive terminals of the second prismatic cells.

There is provided a lithium ion secondary cell excellent in charging and discharging cycle characteristics. A lithium ion secondary cell includes an electrode body including a positive electrode having a positive electrode active material, a negative electrode having a negative electrode active material, and a separator, and a non-aqueous electrolyte containing a lithium salt as a supporting salt in an organic solvent, the electrode body and the non-aqueous electrolyte being accommodated in a case. The positive electrode active material is a lithium transition metal oxide having a spinel type structure. The electrolyte contains a compound represented by a chemical formula (I) in an amount of β mol relative to the total content α mol of moisture to be mixed in the cell. β satisfies −0.8 log(β/α)≦1.5.

A polymer-based electrolyte material for use in lithium ion batteries that exhibits high bulk ion conductivity at ambient and sub-ambient temperatures. The polymer electrolyte comprises a polymer matrix and a liquid electrolyte which is an organic solvent containing a free lithium salt. The polymer matrix is cross-linked and can be formed of cross-linkable ionic monomers, particularly ionic LLC surfactant monomers.
