In some aspects, the present disclosure pertains to methods for the electrochemical production of calcium silicate compounds in an electrochemical cell that comprises (a) a Ca-based electrode that comprises calcium metal or an inorganic calcium material, (b) an SiO-based electrode that comprises a SiOmaterial, where x ranges from 1 to 2, and (c) a liquid electrolyte disposed between the Ca-based electrode and the SiO-based electrode. In these methods, the electrochemical cell is operated under conditions such that calcium cations are produced at the Ca-based electrode and one or more calcium silicate (Ca—Si-oxide) compounds are produced at the SiO-based electrode. In other aspects, the present disclosure pertains to systems for the electrochemical production of calcium silicate compounds.

Electrochemical synthesis of cementitious compounds

Electrochemical devices, and associated materials and methods, are generally described. In some embodiments, an electrochemical device comprises an electroactive material. The electroactive material may comprise an alloy having a solid phase and a liquid phase that co-exist with each other. As a result, such a composite electrode may have, in some cases, the mechanical softness to permit both high energy densities and an improved current density as compared to, for example, a substantially pure metal electrode.

Electrochemical materials including solid and liquid phases

In some aspects, the present disclosure pertains to methods for the electrochemical production of hydrogen in an electrochemical cell comprising an anode, a cathode and a liquid electrolyte comprising an ionic hydrogen carrier, wherein the electrochemical cell is operated under conditions such that hydrogen gas is produced from the ionic hydrogen carrier at the cathode and wherein nitrogen gas is produced from the ionic hydrogen carrier at the anode. Other aspects pertain to devices and systems for carrying out such methods.

Ionic liquid based materials and catalysts for hydrogen release

A method for the efficient management of a fleet of electric vehicles in a target area couples vehicle dynamics and battery dynamics modeling with environmental factors to accurately incorporate the impact that the environment has on the range of the battery into the placement of the chargers by simulating trips of fleets of electric vehicles. The vehicles can be of various types, for example, motorcycles, cars, trucks or aircraft, and will each have their battery state of charge monitored as they traverse a simulated trip through the target area.

Method for managing electric vehicles

The present disclosure is generally related to separators for use in lithium metal batteries, and associated systems and products. Certain embodiments are related to separators that form or are repaired when an electrode is held at a voltage. In some embodiments, an electrochemical cell may comprise an electrolyte that comprises a precursor for the separator.
