  • Patent number: 10556812
    Abstract: The present disclosure describes a flow-electrode capacitive deionization (FCDI) desalination system and method of use. The system employs clusters of tubular membranes oriented parallel to each other, each membrane having an internal flow path capable of receiving an electrolyte slurry (carbon slurry) therethrough. Each tubular membrane further comprises an electrode coaxially extending through the entire length of the electrode. Preferably, adjacent electrodes within the cluster receive a positive or negative charge, respectively. The cluster of tubular membranes is nested within a flow chamber capable of receiving saline or brackish water to be flowed along the outside surfaces of the tubular membranes to cause selected ions, e.g., Na+, Cl— to pass through the membranes and into the carbon slurry circuit. The desalinated water then passes out of the flow chamber. The outer diameter of the electrodes can be optimized based on the inner diameter of the tubular membrane.

    Abstract: An electricity accumulation device includes an electricity accumulation element, an outer jacket material configured to house the electricity accumulation element, and a deformation sensor disposed on an expansive surface of the outer jacket material. The deformation sensor includes a sensor membrane having a base material made of an elastomer or a resin and conductive fillers filling the base material, the sensor membrane being subjected to bending deformation along with expansion of the outer jacket material, and a pair of electrodes connected to the sensor membrane. A three-dimensional conductive path is formed in the sensor membrane through contact between the conductive fillers. An electric resistance is increased along with an increase in amount of deformation of the sensor membrane from a natural state. The electricity accumulation device senses expansion of the outer jacket material on the basis of variations in electric resistance along with bending deformation of the sensor membrane.
