Embodiment Construction

[0035] The present inventors believe that the present invention can be used in some energy storage applications, and have found that the present invention is particularly advantageous for high specific energy batteries based on lithium sulfide cathodes. While the invention is not necessarily limited to such applications, various aspects of the invention can be appreciated by discussing various embodiments with this background.

[0036] As used herein, unless otherwise indicated, the term "cathode" is used to refer to the positive pole / terminal of a battery or cell, and "anode" is used to refer to the negative pole / terminal of a battery or cell. The term "battery pack" is used to mean a collection of one or more cells arranged to provide electrical power. The single cells in the battery pack can be arranged in various forms (such as series connection, parallel connection and combination thereof). The term "thiol" includes elemental sulfur and sulfur compounds such as ionic compo...
