Patent number: 10230124Abstract: The flow cell includes first and second reservoirs having a selected volume containing a flowable redox electrode. A membrane separates charged and discharged material. An energy-extraction region includes electronically conductive porous current collectors through or adjacent to which the flowable redox electrodes flow and to which charge transfer occurs. Structure is provided for altering orientation of the flow cell whereby gravity induces flow of the flowable redox electrode between the first and second reservoirs to deliver power. By varying the angle of the cell, flow rate and power delivered on discharge or the charge rate on charge may be varied.Type: GrantFiled: December 2, 2014Date of Patent: March 12, 2019Assignee: Massachusetts Institute of TechnologyInventors: Brandon James Hopkins, Alexander H.

Publication number: 20170200966Abstract: The present invention generally relates to energy storage devices, and to metal sulfide energy storage devices in particular. Some aspects of the invention relate to energy storage devices comprising at least one flowable electrode, wherein the flowable electrode comprises an electroactive metal sulfide material suspended and/or dissolved in a carrier fluid. In some embodiments, the flowable electrode further comprises a plurality of electronically conductive particles suspended and/or dissolved in the carrier fluid, wherein the electronically conductive particles form a percolating conductive network. An energy storage device comprising a flowable electrode comprising a metal sulfide electroactive material and a percolating conductive network may advantageously exhibit, upon reversible cycling, higher energy densities and specific capacities than conventional energy storage devices.Type: ApplicationFiled: December 21, 2016Publication date: July 13, 2017Applicant: Massachusetts Institute of TechnologyInventors: Yet-Ming Chiang, William Henry Woodford, Frank Y. Fan, Zheng Li, Nir Baram, Kyle C. Smith, W. Craig Carter, Gareth H. McKinley, Ahmed Helal
