Patent number: 11287481Abstract: Systems, devices, and methods of diagnosing an electrochemical cell using cyclic coulometry are discussed. An exemplary battery diagnostic system comprises a current generator to generate symmetric charge current and discharge current to excite an electrochemical cell, and a cyclic coulometer to evaluate performance of the electrochemical cell. The cyclic coulometer can adjust at least one of a charge time for applying the charge current, or a discharge time for applying the discharge current, to keep a monitored cell voltage toward a specific setpoint. The adjustment of charge or discharge time can be achieved by changing a current switch timing for reversing current from a first to a second current direction. The cyclic coulometer measures one or more electrical parameters during the charge or discharge cycle, and generates a performance metric using the measured electrical parameters.Type: GrantFiled: June 5, 2019Date of Patent: March 29, 2022Assignee: Xilectric, Inc.Inventors: Steven E. Weiss, Charles R. Lemay, Andrew Ferencz

Patent number: 11024850Abstract: A lithium-ion battery includes a cathode comprising a lithium compound and the cathode further includes solid additives based on metal nitrides and/or borates. The solid additives improve the capacity retention of the lithium-ion battery and extend the battery lifetime. The solid additives also reduce the growth in internal resistance of the lithium-ion battery that is known to occur as Li-ion batteries age. The solid additives help stabilize the lithium-ion chemistry to high cell potentials or temperatures.Type: GrantFiled: September 25, 2018Date of Patent: June 1, 2021Assignee: XILECTRIC, INC.Inventor: Steven E.

Patent number: 8173010Abstract: The invention relates to materials used as electrodes and/or catalysts, as well as methods associated with the same. The materials may comprise an alloy or intermetallic compound of a transition metal (e.g., Ni) and a metal additive (e.g., Sn). The transition metal and additive are selected to provide improved electrode and/or catalytic performance. For example, the materials of the invention may have a high catalytic activity, while being less susceptible to coking than certain conventional electrode/catalytic materials. These performance advantages can simplify the equipment used in certain applications, as well as reducing energy and capital requirements. Furthermore, the materials may be manufactured using traditional ceramic processing methods, without the need for complex, unconventional fabrication techniques. The materials are particularly suitable for use in fuel cells (e.g., SOFCs electrodes) and in reactions that use or produce synthesis gas.Type: GrantFiled: May 19, 2006Date of Patent: May 8, 2012Assignee: Massachusetts Institute of TechnologyInventors: Jackie Y. Ying, Steven E. Weiss
