摘要:
A stacked energy storage device (ESD) has at least two cell segments arranged in a stack. Each cell segment may have a first electrode unit having a first active material electrode, a second electrode unit having a second active material electrode, and an electrolyte layer between the active material electrodes. Variable volume containment may be used to control the inter-electrode spacing within each cell segment. In some embodiments, one or more dynamic flexible gaskets may be included in each cell segment to seal the electrolyte within the cell segment and to deform in preferred directions. In some embodiments, hard stops may set the inter-electrode spacing of the ESD.

A stacked energy storage device (ESD) has at least two conductive substrates arranged in a stack. Each cell segment may have a first electrode unit having a first active material electrode, a second electrode unit having a second active material electrode, and an electrolyte layer between the active material electrodes. Each active material electrode may have a plurality of folded sections and planar sections to increase the ESD capacity, for example, by increasing number of interfaces within each cell segment.

摘要:
An energy storage device is provided that includes a bipolar conductive substrate having a first side coupled to a first substack and a second side coupled to a second substack. The first and second substacks have a plurality of alternately stacked positive and negative monopolar electrode units. Each respective monopolar electrode unit has a first and second active material electrode layer on opposing sides of a conductive pathway. A separator is provided between adjacent monopolar electrode units. The conductive pathways of the positive monopolar electrode units are electronically coupled to form a positive tabbed current bus, and the conductive pathways of the negative monopolar electrode units are electronically coupled to form a negative tabbed current bus. The negative tabbed current bus of the first substack and the positive tabbed current bus of the second substack are coupled to the first and second side of the bipolar conductive substrate respectively.
摘要:
Charge information associated with an energy storage device may be determined from one or more kinetic responses of the energy storage device. Kinetic responses may include displacements, forces, pressures, or other kinetic properties, and changes in properties thereof. An indication device, such as a sensor, transducer, or other device, may be used to indicate kinetic responses. Charge information, measurements, or both, may be derived from indications of kinetic responses. Charging or discharging of an energy storage device may be controlled based on charge information.

Electrode structures may include an electronically conductive foam in contact with an electronically conductive substrate. In some embodiments, the foam may be formed by coating a porous precursor material in contact with a substrate with an electronically conductive material and subsequently removing the precursor material. In some embodiments, the foam may be formed by removing a non-conductive component of a composite material in contact with a substrate, leaving a conductive component in contact with the substrate. Electrode structures may be coated with electronically conductive materials or sintered at elevated temperature to improve durability and conductivity.
摘要:
Apparatus and methods are provided for energy storage devices capable of mitigating the pressure differentials between adjacent bi-polar units using a pressure equalization valve at a projection from a substrate of a bi-polar unit, which prevents the pressure equalization valve from being submerged by free liquid in the unit.
