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.

A process for the formation of a deformable battery electrode includes mixing a metal component including at least one of a metal or a metal alloy, a polymer component, and a dispersant component to create a mixture. The method further includes heated the mixture to a temperature above the melting point of the metal or the metal alloy and agitating the mixture to form a dispersion of the (molten) metal or the metal alloy in the mixture. The method further includes cooling the mixture to a temperature below the melting point of the metal or the metal alloy to form a stabilized dispersion of the metal or the metal alloy. The polymer component includes a polymer having a melting point equal to or below that of the metal or the metal alloy and a glass transition temperature sufficiently low that the stabilized dispersion is deformable.

A memory stores a stream of capture data instances derived from ultrasound energy exiting the energy storage device and baseline ultrasound data instances corresponding with the energy storage device during normal charging/discharging thereof. A processor can compare each capture data instance with the baseline ultrasound data and detect abnormal operating states of the energy storage device. A warning system can issue a notification when abnormal operating states are detected.

Systems, methods, and devices for failure detection of one or more energy storage devices

Methods and software for electrochemical energy storage management including operation, planning, and valuation. The decision objective for operation is to maximize the total/remaining life-cycle benefit of electrochemical energy storage, subject to degradation and other operational constraints. The operational decisions are both short term and long term, to address the intertemporal trade-offs brought by degradation issues. Two metrics are proposed for operational and planning decisions respectively: marginal benefit of usage and average benefit of usage. A sample algorithm is provided to solve the multi-timescale optimization problem.
