Abstract: A hybrid lithium-ion battery/capacitor cell comprising at least a pair of graphite anodes assembled with a lithium compound cathode and an activated carbon capacitor electrode can provide useful power performance properties and low temperature properties required for many power utilizing applications. The graphite anodes are formed of porous layers of graphite particles bonded to at least one side of current collector foils which face opposite sides of the activated carbon capacitor. The porous graphite particles are pre-lithiated to form a solid electrolyte interface on the anode particles before the anodes are assembled in the hybrid cell. The pre-lithiation step is conducted to circumvent the irreversible reactions in the formation of a solid electrolyte interface (SEI) and preserve the lithium content of the electrolyte and lithium cathode during formation cycling of the assembled hybrid cell. The pre-lithiation step is also applicable to other anode materials that benefit from such pre-lithiation.

Abstract: Electrodes are formed with a porous layer of particulate electrode material bonded to each of the two major sides of a compatible metal current collector. In one embodiment, opposing electrodes are formed with like lithium-ion battery anode materials or like cathode materials or capacitor materials on both sides of the current collector. In another embodiment, a battery electrode material is applied to one side of a current collector and capacitor material is applied to the other side. In general, the electrodes are formed by combining a suitable grouping of capacitor layers with un-equal numbers of anode and cathode battery layers. One or more pairs of opposing electrodes are assembled to provide a combination of battery and capacitor energy and power properties in a hybrid electrochemical cell. The cells may be formed by stacking or winding rolls of the opposing electrodes with interposed separators.

Abstract: A method for reducing residual water content in a battery material includes placing the battery material having residual water adsorbed therein in a channel substantially sealed from an ambient environment. A gaseous mixture is caused to flow through the battery material in the channel. The gaseous mixture includes an organic solvent vapor present in an amount effective to hydrogen bond with at least some water molecules from the battery material. The gaseous mixture is caused to flow through the battery material for a predetermined amount of time, at a predetermined temperature, and at a predetermined pressure. The organic solvent vapor having at least some water molecules bonded thereto is removed from the battery material. The removing takes place for a predetermined amount of time, at a predetermined temperature, and at a predetermined pressure, thereby forming the battery material having reduced residual water content.

Abstract: One or more vehicle systems and methods of operating a vehicle using wireless communications are disclosed. One method includes establishing a temperature threshold for a cold-start of the vehicle; receiving a remote vehicle start request via a wireless signal, wherein the remote vehicle start request is a request to start a motor of the vehicle; when the remote vehicle start request is received, indicating that the motor of the vehicle has failed to start; communicating with a self-heating battery on-board the vehicle the indication that the motor of the vehicle has failed to start; obtaining a temperature of a working battery on-board the vehicle or a temperature around the vehicle; when the temperature obtained of the working battery or around the vehicle is less than or equal to the temperature threshold for the cold-start of the vehicle, operating the self-heating battery to heat the working battery; and sending another vehicle start request wherein the another vehicle start request starts the motor of the vehicle.
