A electrical cable includes one or more conductor sets, one or more reservoirs (2450), first and second conductive shielding films (2408) disposed on opposite first and second sides of the conductor sets and the reservoirs (2450), and an adhesive layer (2440). The shielding films include cover portions and pinched portions arranged such that, in cross-section, the cover portions of the shielding films in combination substantially surround each conductor set and reservoir, and the pinched portions of the shielding films in combination form pinched portions of the cable on each side of the conductor set and on at least one side of the reservoir (2450). The adhesive layer (2440) bonds the first shielding film to the second shielding film in the pinched portions of the electrical cable. The first and second shielding films (2408) comprise respective first and second conductive layers (2420) disposed on respective first and second substrates (2410), the first and second conductive layers (2420) facing each other, and wherein in a cover portion (2410) corresponding to a reservoir (2450), the first conductive layer, but not the first substrate, comprises an opening (2420c) extending along at least a portion of the length of the electrical cable, and the first substrate in the cover portion is elongated laterally relative to the first substrate on each side of the cover portion.

Most studies set out to make materials that improve on the specific capacity of graphite, usually without regard to average voltage, volumetric capacity, or the many other properties listed above that are more applicable to implementation in practical cells. One difficulty in choosing proper metrics for anodes stems from basic electrochemistry: it is not possible to calculate the energy of a single electrode. To provide motivation for using alloy anode materials and a framework for comparison, key performance metrics need to be defined. It is well-known that the volumetric and specific capacities of the active elements are far greater than that of graphite. Because all alloys expand considerably during lithiation, this volume must be accommodated somewhere within a battery. To make more informative performance comparisons, it is necessary to use a cell model, preferably one that is most representative of alloy materials application.
