Various embodiments provide a battery, a bulk energy storage system including the battery, and/or a method of operating the bulk energy storage system including the battery. In various embodiment, the battery may include a first electrode, an electrolyte, and a second electrode, wherein one or both of the first electrode and the second electrode comprises direct reduced iron ('DRI'). In various embodiments, the DRI may be in the form of pellets. In various embodiments, the pellets may comprise at least about 60 wt % iron by elemental mass, based on the total mass of the pellets. In various embodiments, one or both of the first electrode and the second electrode comprises from about 60% to about 90% iron and from about 1% to about 40% of a component comprising one or more of the materials selected from the group of SiO, AlO, MgO, CaO, and TiO.

Negative electrodes for electrochemical cells

A through-the-road (TTR) hybridization strategy is proposed to facilitate introducing hybrid electric vehicle technology in a significant portion of current and expected trucking fleets. In some cases, the technologies can be retrofitted onto an existing vehicle (e.g., a trailer, a tractor-trailer configuration, etc.). In some cases, the technologies can be built into new vehicles. In some cases, one vehicle may be built or retrofitted to operate in tandem with another and provide the hybridization benefits contemplated herein. By supplementing motive forces delivered through a primary drivetrain and fuel-fed engine with supplemental torque delivered at one or more electrically-powered drive axles, improvements in overall fuel efficiency and performance may be delivered, typically without significant redesign of existing components and systems that have been proven in the trucking industry.

Trailer-based energy capture and management

Systems and methods of the various embodiments may provide device architectures for batteries. In various embodiments, these may be primary or secondary batteries. In various embodiments these devices may be useful for energy storage. Various embodiments may provide a battery including an Oxygen Reduction Reaction (ORR) electrode, an Oxygen Evolution Reaction (OER) electrode, a metal electrode; and an electrolyte separating the ORR electrode and the OER electrode from the metal electrode.

Device architectures for metal-air batteries

Systems and methods of the various embodiments may provide metal electrodes for electrochemical cells. In various embodiments, the electrodes may comprise iron. Various methods may enable achieving high surface area with low cost for production of metal electrodes, such as iron electrodes.

Low cost metal electrodes

Systems and methods of the various embodiments may provide metal air electrochemical cell architectures. Various embodiments may provide a battery, such as an unsealed battery or sealed battery, with an open cell arrangement configured such that a liquid electrolyte layer separates a metal electrode from an air electrode. In various embodiments, the electrolyte may be disposed within one or more vessel of the battery such that electrolyte serves as a barrier between a metal electrode and gaseous oxygen. Systems and methods of the various embodiments may provide for removing a metal electrode from electrolyte to prevent self-discharge of the metal electrode. Systems and methods of the various embodiments may provide a three electrode battery configured to operate each in a discharge mode, but with two distinct electrochemical reactions occurring at each electrode.

Metal air electrochemical cell architecture

Systems and methods of the various embodiments may provide a battery including a rolling diaphragm configured to move to accommodate an internal volume change of one or more components of the battery. Systems and methods of the various embodiments may provide a battery housing including a rolling diaphragm seal disposed between an interior volume of the battery and an electrode assembly within the battery. Various embodiments may provide an air electrode assembly including an air electrode supported on a buoyant platform such that the air electrode is above a surface of a volume of electrolyte when the buoyant platform is floating in the electrolyte.

Stack of electric batteries including series of fluidly connected unit cells

A through the road (TTR) hybridization strategy is proposed to facilitate introduction of hybrid electric vehicle technology in a significant portion of current and expected trucking fleets. In some cases, the technologies can be retrofitted onto an existing vehicle (e.g., a trailer, a tractor-trailer configuration, etc.). In some cases, the technologies can be built into new vehicles. In some cases, one vehicle may be built or retrofitted to operate in tandem with another and provide the hybridization benefits contemplated herein. By supplementing motive forces delivered through a primary drivetrain and fuel-fed engine with supplemental torque delivered at one or more electrically-powered drive axles, improvements in overall fuel efficiency and performance may be delivered, typically without significant redesign of existing components and systems that have been proven in the trucking industry.

An electrochemical cell and battery system including cells, each cell including a catholyte, an anolyte, and a separator disposed between the catholyte and anolyte and that is permeable to the at least one ionic species (for example, a metal cation or the hydroxide ion). The catholyte solution includes a ferricyanide, permanganate, manganate, sulfur, and/or polysulfide compound, and the anolyte includes a sulfide and/or polysulfide compound. These electrochemical couples may be embodied in various physical architectures, including static (non-flowing) architectures or in flow battery (flowing) architectures.
