Publication number: 20180277864Abstract: High performance flow batteries, based on alkaline zinc/ferro-ferricyanide rechargeable (“ZnFe”) and similar flow batteries, may include one or more of the following improvements. First, the battery design has a cell stack comprising a low resistance positive electrode in at least one positive half cell and a low resistance negative electrode in at least one negative half cell, where the positive electrode and negative electrode resistances are selected for uniform high current density across a region of the cell stack. Second, a flow of electrolyte, such as zinc species in the ZnFe battery, with a high level of mixing through at least one negative half cell in a Zn deposition region proximate a deposition surface where the electrolyte close to the deposition surface has sufficiently high zinc concentration for deposition rates on the deposition surface that sustain the uniform high current density.Type: ApplicationFiled: May 30, 2018Publication date: September 27, 2018Inventors: Joseph Grover GORDON, II, Alan J. GOTCHER, Godfrey SIKHA, Gregory J. WILSON

Patent number: 6271823Abstract: An ambient light reflective color electrophoretic display is comprised of a plurality of color pixels; each comprised of at least two electrophoretic cells. Each cell is comprised of a suspension of charged, black or colored light-absorbing pigment particles in a light-transmissive fluid. Each cell is also comprised of a light-transmissive front window, at least one non-obstructing counter electrode, at least one non-obstructing collecting electrode, a light-reflective panel, and a color filter medium. The cells of different colors are in a laterally adjacent relationship to each other and the charged pigment particles are responsive to the electrodes. The filter medium in each cell can be a light-transmissive color filter element or a light-reflective colored surface or the pigment suspension fluid can be colored and serve as the filter medium.Type: GrantFiled: September 16, 1998Date of Patent: August 7, 2001Assignee: International Business Machines CorporationInventors: Joseph Grover Gordon, II, Mark Whitney Hart, Sally Ann Swanson

Patent number: 6225971Abstract: An ambient light reflective color electrophoretic display is comprised of a plurality of color pixels; each comprised of at least two electrophoretic cells. Each cell is comprised of a suspension of charged, white or colored light-scattering pigment particles in a light-transmissive fluid. Each cell is also comprised of a light-transmissive front window, at least one non-obstructing counter electrode, at least one non-obstructing collecting electrode, a light-absorbing panel, and a color filter medium. The cells of different colors are in a laterally adjacent relationship to each other and the charged pigment particles are responsive to the electrodes. The filter medium in each cell can be a light-transmissive color filter element. Alternatively, the pigment suspension fluid itself or the pigment particles themselves can be colored and serve as the filter medium.Type: GrantFiled: September 16, 1998Date of Patent: May 1, 2001Assignee: International Business Machines CorporationInventors: Joseph Grover Gordon, II, Mark Whitney Hart, Sally Ann Swanson

Patent number: 6184856Abstract: A transmissive electrophoretic color display is comprised of a plurality of color pixels; each uniformly illuminated from the rear by a backlight and each comprised of at least two electrophoretic cells. Each cell is comprised of a suspension of charged, black or colored light-absorbing pigment particles in a light-transmissive fluid. Each cell is also comprised of a light-transmissive front and rear window, at least one non-obstructing counter electrode, at least one non-obstructing collecting electrode, and a color filter medium. The cells of different colors are in a laterally adjacent relationship to each other and the charged pigment particles are responsive to the electrodes. The filter medium in each cell can be a light-transmissive color filter element or the pigment suspension fluid can be colored and serve as the filter medium.Type: GrantFiled: September 16, 1998Date of Patent: February 6, 2001Assignee: International Business Machines CorporationInventors: Joseph Grover Gordon, II, Mark Whitney Hart, Sally Ann Swanson

Patent number: 6144361Abstract: A transmissive electrophoretic display is generally comprised of a regular lateral array of transmissive electrophoretic cells; each uniformly illuminated from the rear by a backlight. Each cell is comprised of a suspension of charged, black or colored light-absorbing pigment particles in a light-transmissive fluid. Each cell is also comprised of a light-transmissive front and rear window, at least one non-obstructing counter electrode, and at least one non-obstructing, vertically-disposed collecting electrode. With the application of appropriate voltages to the collecting and counter electrodes, each cell can be switched between a light and dark state. In the dark state, the light-absorbing pigment particles are distributed to cover the horizontal area of the cell, thus absorbing light from the backlight and preventing it from reaching the viewer.Type: GrantFiled: September 16, 1998Date of Patent: November 7, 2000Assignee: International Business Machines CorporationInventors: Joseph Grover Gordon, II, Mark Whitney Hart, Sally Ann Swanson
