An auxiliary electrode is provided in the cell at least prior to its formation cycling and is used to supply lithium to the negative electrode. The auxiliary electrode may be then removed from the cell prior or after formation. The transfer of lithium to the negative electrode may be performed using a different electrolyte, a higher temperature, and/or a slower rate than during later operational cycling of the cell. After this transfer, the negative electrode may remain pre-lithiated during later cycling at least at a certain predetermined level. This pre-lithiation helps to cycle the cell at more optimal conditions and to some degree maintain this cycling performance over the operating life of the cell.

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.

Method for manufacturing nonaqueous electrolyte secondary battery

Автор: Yasuhiko Takemura

Принадлежит: Semiconductor Energy Laboratory Co Ltd

When an active material with low ionic conductivity and low electric conductivity is used in a nonaqueous electrolyte secondary battery such as a lithium ion battery, it is necessary to reduce the sizes of particles; however, reduction in sizes of particles leads to a decrease in electrode density. Active material particles of an oxide, which include a transition metal and have an average size of 5 nm to 50 nm, are mixed with an electrolyte, a binder, and the like to form a slurry, and the slurry is applied to a collector. Then, the collector coated with the slurry is exposed to a magnetic field. Accordingly, the active material particles aggregate so that the density thereof increases. Alternatively, the active material particles may be applied to the collector in a magnetic field. The use of the aggregating active material particles makes it possible to increase the electrode density.

A nanoconverter or nanosensor is disclosed capable of directly generating electricity through physisorption interactions with molecules that are dipole containing organic species in a molecule interaction zone. High surface-to-volume ratio semiconductor nanowires or nanotubes (such as ZnO, silicon, carbon, etc.) are grown either aligned or randomly-aligned on a substrate. Epoxy or other nonconductive polymers are used to seal portions of the nanowires or nanotubes to create molecule noninteraction zones. By correlating certain molecule species to voltages generated, a nanosensor may quickly identify which species is detected. Nanoconverters in a series parallel arrangement may be constructed in planar, stacked, or rolled arrays to supply power to nano- and micro-devices without use of external batteries. In some cases breath, from human or other life forms, contain sufficient molecules to power a nanoconverter. A membrane permeable to certain molecules around the molecule interaction zone increases specific molecule nanosensor selectivity response.
