Принадлежит: US Department of Army

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.

Provided are novel electrochemical cells that include positive electrodes, negative electrodes containing high capacity active materials such as silicon, and auxiliary electrodes containing lithium. 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.

Internal cell temperature may be determined with respect to an internal anode temperature and/or an internal cathode temperature. Internal anode temperature may be determined based on a phase shift of a frequency within a range of approximately 40 Hertz (Hz) to 500 Hz. Internal cathode temperature may be determined based on a phase shift of a frequency of up to approximately 30 Hz. A temperature sensor as disclosed herein may be powered by a monitored cell with relatively little impact on cell charge, may be electrically coupled to cell but housed physically separate from the cell, and/or may monitor multiple cells in a multiplex fashion. A rate of change in phase shift may be used to initiate pre-emptive action, without determining corresponding temperatures.

The present invention provides a method of producing a composite particle for high density electrochemical element electrodes in electrochemical elements having low internal resistance and high capacitance. Slurry containing an electric conductive material and a binder is obtained, and the slurry is sprayed to a fluidized electrode active material to carry out fluidized-granulation, and further particles obtained by the fluidized-granulation are rolling-fluidized granulated, and thereby, composite particle for electrochemical element electrode, containing electrode active materials, electric conductive materials, and binders, and being structured of an outer layer portion (outer shell portion) and an inner layer portion (core portion) are obtained.
