Abstract: An electrochemical storage device including a plurality of electrochemical cells connected electrically in series. Each cell includes an anode electrode, a cathode electrode and an aqueous electrolyte. The charge storage capacity of the anode electrode is less than the charge storage capacity of the cathode.

Abstract: An electrochemical device including a housing and a stack of electrochemical cells in the housing. Each electrochemical cell includes an anode electrode, a cathode electrode, a separator located between the anode electrode and the cathode electrode and an electrolyte. The electrochemical device also includes a current collector located between adjacent electrochemical cells, an anode bus operatively connected to the anodes of the electrochemical cells in the stack and a cathode bus operatively connected to the cathodes of the electrochemical cells in the stack. The housing, the anode electrode, the cathode electrode, the separator, the anode bus and the cathode bus are non-metallic.

Abstract: An anode electrode for an energy storage device includes both an ion intercalation material and a pseudocapacitive material. The ion intercalation material may be a NASICON material, such as NaTi2(PO4)3 and the pseudocapacitive material may be an activated carbon material. The energy storage device also includes a cathode, an electrolyte and a separator.

Abstract: An electrochemical energy device includes a device housing and a pass-through connector extending through a wall of the device housing. The pass-through connector may include an electrically insulating connector housing having a quick connect feature and an electrically conductive pin located in the connector housing.

Abstract: An electrochemical energy storage system including at least a first type of electrochemical cell and a second type of electrochemical cell. The first type of electrochemical cell and the second type of electrochemical cell have different geometries. Also methods of making and using the electrochemical energy storage system.

Abstract: An assembly includes non-load bearing housings, each housing including several cavities. Each cavity includes a stack of freely stacked electrochemical storage cells in the housings. Each electrochemical storage cell includes an anode electrode, a cathode electrode, and a separator located between the anode electrode and the cathode electrode. The assembly is configured such that pressure applied to the assembly is born by the freely stacked electrochemical storage cells.
