Abstract: Electrochemical systems with electronically and ionically conductive layers have electronic, mechanical and chemical properties useful for a variety of applications including electrochemical storage and conversion. Electronically and ionically conductive layers may be introduced between an electrode and the separator. Embodiments provide structural, physical and electrostatic attributes useful for managing and controlling dendrite formation and for improving the cycle life and rate capability of electrochemical cells including silicon anode based batteries, air cathode based batteries, redox flow batteries, solid electrolyte based systems, fuel cells, flow batteries and semisolid batteries and may include multilayer, porous geometries supporting excellent ion transport properties, providing a barrier to prevent dendrite initiated mechanical failure, shorting or thermal runaway, or providing improved electrode conductivity and improved electric field uniformity. An electronically and ionically conductive layer may provide electronic conductivity greater than or equal to 1 S/cm and ionic resistance less than or equal to 10 Ωcm2.

Abstract: A system and method for monitoring characteristics of an electric energy device includes generating an external short from the electric energy device. The external short occurs at a known distance from a sensor and has at least one known external resistance. The received signal representing change in electromagnetic field due to the applied external short may be analyzed to determine a signal parameter that is then analyzed in comparison to a lookup table, based on the known conditions including distance, temperature and the external resistance. The output of this analyses in comparison with expected values may be utilized to identify a characteristic of the energy device.

Abstract: A plurality of battery packs is provided in communication with an energy monitoring and control system. Each battery pack includes a plurality of battery cells that collectively dictate the capabilities of the battery pack. The energy monitoring and control system determines a plurality of pack charging or pack discharging parameters for each battery pack that, when performed, achieve one or more performance metrics at a user level (e.g., performance metrics of each battery pack within a system of multiple battery packs). The battery pack further determines a plurality of cell charging or cell discharging parameters for each battery cell based upon the determined plurality of pack charging or pack discharging parameters for each battery cell that, when performed, achieve one or more performance metrics at a battery level (e.g., performance metrics of different cells of each battery pack).
