Abstract: An electrochemical device includes a transition metal oxide cathode, such as LiNi0.8Co0.1Mn0.1O2, and an electrolyte. The electrolyte includes N, N-dimethyltrifluoromethane-sulfonamide (DMTMSA) and lithium bis(fluorosulfonyl)imide (LiFSI). The DMTMSA and LiFSI may be either the primary component of the electrolyte or an additive in the electrolyte. The electrochemical device may also include a graphite anode or a lithium metal anode. With a lithium metal anode, the electrochemical device has an initial specific capacity of at least 231 mAh g?1. Over at least 100 cycles (upper cut-off voltage of 4.7±0.05 V vs. Li/Li+), the electrochemical device maintains an average specific capacity of at least 88% of the initial specific capacity and an average Coulombic efficiency of at least about 99.65%.

Abstract: A structural supercapacitor, and methods of manufacturing, composed of a conductive composite is described herein. An embodiment of the composite has a controllable transport porosity, that enables transport of electrical charge, via electrolyte solution, to a distributed conductive network within the composite. The distributed conductive network has a controllable storage porosity that enables the storage of electrical charge. The conductive composite can be used in a variety of different fields of use, including, for example, a structural super-capacitor as an energy solution for autonomous housing and other buildings, a heated cement for pavement de-icing or house basement insulation against capillary rise, a protection of concrete against freeze-thaw (FT) or alkali silica reaction (ASR) or other crystallization degradation processes, and as a conductive cable, wire, or concrete trace.

Abstract: A class of sulfonimide salts for solid-state electrolytes can be synthesized based on successive SNAr reactions of fluorinated phenyl sulfonimides: Fluorinated Aryl Sulfonimide Tags (FAST). The chemical and electrochemical oxidative stability of these FAST salts as well as other properties like solubility, Lewis basicity, and conductivity can be tuned by introducing different numbers and types of nucleophilic functional groups to the FAST salt scaffold.

Abstract: A flexible Zn film electrode with ionic and electronic networks has been designed by utilizing ionic liquid based gel polymer as the binder, which can minimize the interface resistance between electrode and electrolytes. Ionic liquid electrolytes are good candidates for high surface area Zn anode due to their good electro(chemical) stability. Ionic liquid based gel polymer electrolytes (GPEs) are good candidates to replace liquid electrolytes or separators in some special applications, like surface coating structure batteries.

In some aspects, the solid-state electrolytes demonstrate high ion conductivity at room temperature.

Abstract: Corrosion mitigation in a battery may include displacing a first flowable medium with a second flowable medium along a first electrode to interrupt fluid communication of the first flowable medium with the first electrode—thus interrupting operation of the battery—while a second electrode remains in contact with a flowable medium (e.g., one or more of the first flowable medium or another flowable medium, such as a gel). For example, a membrane (e.g., an underwater oleophobic material) may be disposed between the first electrode and the second electrode. An oil may displace an aqueous electrolyte on a first side of the membrane toward a metallic electrode while the aqueous form of the electrolyte remains in contact with an air electrode on a second side of the separator membrane disposed toward the air electrode.
