A doped electrode may be manufactured by doping an active material included in an electrode with an alkali metal in a dope solution containing a first aprotic solvent and an alkali metal salt. The doped electrode may be cleaned with a cleaning solution containing a second aprotic solvent that has a boiling point lower than that of the first aprotic solvent. The cleaning solution may be controlled such that a content ratio of the first aprotic solvent in the cleaning solution is 8 vol % or lower.

Methods and systems for the electrochemical conversion of halogenated compounds are provided. In some embodiments, a method comprises converting a halogenated compound (e.g., fluorinated gas) to relatively non-hazardous products via one or more electrochemical reactions. The electrochemical reaction(s) may occur under relatively mild conditions (e.g., low temperature) and/or without the aid of a catalyst. In some embodiments, the electrochemical reaction may produce a relatively large amount of energy. In some such cases, systems, described herein, may be designed to facilitate the conversion of the halogenated compound (e.g., SF.sub.6, NF.sub.3) while harnessing (e.g., storing, converting) the energy associated with the electrochemical reaction. System and methods described herein may be used in a wide variety of applications, including waste management (e.g., environmental remediation, greenhouse gas mitigation), energy recovery (e.g., industrial energy recovery), and primary batteries (e.g., metal-gas batteries).

In a metal negative electrode, a current collector includes a through-hole or a recess provided to extend from a front surface of a planar plate toward a back surface of the planar plate. A distance from a midpoint of a joining boundary to a point on a surface of the current collector is designated as a region dividing distance, the point defining a distance less than a maximum distance between the midpoint and a side or a surface of the current collector. In the current collector, a first region is a region defined by distances from the midpoint, the distances being a distance equal to the region dividing distance and distances greater than the region dividing distance, and, in the current collector, a second region is a region defined by distances from the midpoint that are less than the region dividing distance. A volume reduction ratio of the first region is greater than a volume reduction ratio of the second region, the volume reduction ratio of the first region being a ratio with respect to a volume of the first region determined assuming that the through-hole or the recess is not present, the volume reduction ratio of the second region being a ratio with respect to a volume of the second region determined assuming that the through-hole or the recess is not present.
