The battery operates via an electrochemical reaction that entails an actual transport of aluminum ions between the anode and cathode. The compositions and structures described herein allow the aqueous aluminum ion battery described herein to achieve: (1) improved charge storage capacity; (2) improved gravimetric and/or volumetric energy density; (3) increased rate capability and power density (ability to charge and discharge in shorter times); (4) increased cycle life; (5) increased mechanical strength of the electrode; (6) improved electrochemical stability of the electrodes; (7) increased electrical conductivity of the electrodes, and (8) improved ion diffusion kinetics in the electrodes as well as the electrolyte.

Abstract: Described herein are, inter alia, electrodes for use in energy storage devices, such as a cathode or anode in a battery. An electrode may include a substrate which serves as a reaction site that occur during electrochemical cycling of an energy storage device. In some embodiments, an electrode can undergo intercalation chemistry, conversion chemistry, plating-stripping/deposition-dissolution chemistry, or combinations thereof. A film and/or additive may be provided in an electrode in order to mitigate side reactions and/or electrochemical passivation reactions. An electrode may include one or more materials that (i) electrochemically reduce a portion of the electrolyte to a gas during electrochemical cycling, (ii) suppress generation of hydrogen gas by increasing a hydrogen evolution overpotential, (iii) constrain gas after formation, and/or (iv) catalyze oxidation of a gas back into an electrolyte. An electrode may include one or more electroactive materials in addition to a substrate.

Abstract: Separators and additives (e.g., electrode additives) for use in energy storage devices are disclosed. In certain embodiments, a separator includes inorganic particles. In certain embodiments, an additive includes inorganic particles. The additive may be used in an electrode, such as a cathode or anode in a battery. The inorganic particles (whether included in a separator or used in (e.g., as) an additive, for example for an electrode) may be functional inorganic particles that promote battery performance and/or safety. For example, the functional inorganic particles may act to reduce or eliminate side reactions or mitigate the effects of side reactions during electrochemical cycling of an energy storage device in which they are included (e.g., discharge and/or charge of a battery). As another example, the functional inorganic particles may additionally or alternatively promote ionic conductivity.

Abstract: The technology relates to a system and a method for assessing and negotiating compensation of a human resource (candidate). Upon selection of a candidate(s), the method comprises of receiving compensation information of the candidate(s). The compensation assessment and negotiation system generates a salary proposal based on at least one of the compensation data, an assessment score of the candidate, a location, a minimum wage, a threshold salary and a recruitment policy. The compensation assessment and negotiation system also allows the candidate to negotiate the salary proposal by submitting a second salary proposal to the system. The compensation assessment and negotiation system thereafter generates a revised salary proposal in response to the second salary proposal. The compensation assessment and negotiation system rolls an offer to the candidate upon receiving a positive response on the salary proposal.

Abstract: The present invention relates to a system and a method for conducting life-cycle engagement of a candidate without human intervention on device engagement architecture. The implementation involves selecting initially, from a plurality of potential candidates based on any or a combination of pre-screening based on a set of pre-defined requirement rules and assessment with respect to multiple engagement criteria. An artificial intelligence (AI) engine associated with the system, evaluates the candidate based on responses to one or more responsive video frames generated by the AI engine. Based on a combination of the pre-screening, the assessment, and the AI engine based evaluation, the system generates a score for the at least one candidate, wherein the candidate is finally engaged based on the generated score.

Abstract: Disclosed herein are electrochemical cells and their components. An electrochemical cell may include two electrodes, such as an anode and a cathode, an electrolyte, and, optionally, a separator. An electrochemical cell may include a surface layer. The surface layer may be formed in situ or ex situ and may be grown from or grown into an electrode surface, for example by a pre-treatment, a formation process, and/or during electrochemical cycling. The surface layer may be formed directly on an electrode material, such as an electroactive material or current collector, or on a layer disposed thereon, such as a carbon layer formed by carbonization. A surface layer may be solid or semi-solid, for example a gel or gelatinous. A surface layer may include one or more of: cation(s), anion(s), and functional group(s) that have reacted together. A surface layer may be a charge storage layer/film or a passivation layer.
