A power supply may include a number of power supply coils disposed in, on, or about a power supply member. Some or all of the power supply coils may wirelessly couple to the at least one receiver coil via an electromagnetic field and transfer energy to the electronic device when the electronic device is disposed proximate the power supply.

The present disclosure provides systems and methods for managing a temperature of a battery energy storage system (“BESS”). A method may comprise obtaining a charge/discharge schedule for a battery energy storage system (BESS) for a first time period; identifying, from the charge/discharge schedule, a charge or discharge time period of the BESS within the first time period; calculating a beginning time of a temperature control time period in which equipment operates to control a temperature of the BESS to reach a target temperature by a beginning time of the charge or discharge time period; and controlling the equipment operating to control the temperature of the BESS for the temperature control time period such that the temperature of the BESS reaches the target temperature by the beginning time of the charge or discharge time period.

An electronic device includes a flexible display. A device housing provides a translation surface for the flexible display. A rotor positioned within a curvilinear section of the flexible display rotates with translation of the flexible display across the translation surface. The rotor can be a rechargeable electrochemical cell, can be a rechargeable electrochemical cell situated within a sheath, or can be positioned within a housing defining an outer surface of the rotor to save space within the electronic device.

Example implementations relate to novel battery designs based on the original disclosures of the Parent patent application Ser. No. 15/196,019. In a non-limiting embodiment, a first battery includes a ferroelectric glass electrolyte and a ferrocene Fe(C.sub.5H.sub.5).sub.2 molecule as a redox-mediator-relay material used for plating sodium on a current collector. Novel redox Fe(C.sub.5H.sub.5).sub.2 behavior is shown at a fixed (or a finite) voltage under discharge conditions. The disposed ferroelectric electrolyte material is predisposed to align itself in the direction of the electric field inside the battery, increasing the capacity of the battery. This description is not intended to be a complete description of, or to limit the scope of, the invention.
