Abstract: In some variations, an apparatus provides real-time monitoring of voltage and differential voltage of both anode and cathode in a battery configured with at least one reference electrode. Voltage monitors are connected to a computer programmed for receiving anode voltage signals; receiving cathode voltage signals; calculating the derivative of the anode voltage with respect to time or with respect to capacity; and calculating the derivative of the cathode voltage with respect to time or with respect to capacity. Other variations provide an apparatus for real-time assessment of capacities of both anode and cathode in a battery, comprising a computer programmed for receiving electrode voltage signals; estimating first and second electrode open-circuit voltages at two different times, and correlating the first and second electrode open-circuit voltages to first and second electrode states of charge, respectively, for each of anode and cathode. The anode and cathode capacities may then be estimated independently.

Abstract: The internal temperature of an electrochemical device may be probed without a thermocouple, infrared detector, or other auxiliary device to measure temperature. Some methods include exciting an electrochemical device with a driving profile; acquiring voltage and current data from the electrochemical device, in response to the driving profile; calculating an impulse response from the current and voltage data; calculating an impedance spectrum of the electrochemical device from the impulse response; calculating a state-of-charge of the electrochemical device; and then estimating internal temperature of the electrochemical device based on a temperature impedancestate-of-charge relationship. The electrochemical device may be a battery, fuel cell, electrolytic cell, or capacitor, for example. The procedure is useful for on-line applications which benefit from real-time temperature sensing capabilities during operations. These methods may be readily implemented as part of a device management and safety system.

Abstract: Antimicrobial coatings that are transparent and not easily stained are disclosed. Some variations provide a transparent antimicrobial structure comprising: a discrete solid structural phase comprising a solid structural polymer with a glass-transition temperature from 25°C to 300°C; a continuous transport phase interspersed within the discrete solid structural phase, wherein the continuous transport phase comprises a solid transport material; and an antimicrobial agent contained within the continuous transport phase, wherein the antimicrobial agent is dissolved in a fluid and/or in a solid solution with the continuous transport phase. The discrete solid structural phase and the continuous transport phase are separated by an average phase-separation length selected from 100 nanometers to 500 microns. This invention resolves the trade-off between antifouling and fluorinated material content. This invention also resolves the trade-off between transport of absorbed molecules and transparency. The result is an improved antimicrobial structure that is both antifouling and transparent.

Abstract: This disclosure describes incorporation of a liquid additive within one or more phases of a multiphase polymer coating. The structure of the microphase-separated network provides reservoirs for liquid in discrete and/or continuous phases. Some variations provide an anti-fouling segmented copolymer composition comprising: (a) one or more first soft segments selected from fluoropolymers; (b) one or more second soft segments selected from polyesters or polyethers; (c) one or more isocyanate species; (d) one or more polyol or polyamine chain extenders or crosslinkers; and (e) a liquid additive disposed in the first soft segments and/or the second soft segments. The first soft segments and the second soft segments are microphase-separated on a microphase-separation length scale from 0.1 microns to 500 microns. These solid/liquid hybrid materials improve physical properties associated with the coating in applications such as anti-fouling (e.g., anti-ice or anti-bug) surfaces, ion conduction, and corrosion resistance.

Some embodiments provide an anti-corrosion composition comprising first corrosion-inhibitor particles or precursors selectively dispersed within the first polymer material, wherein the multiphase polymer composition optionally further comprises second corrosion-inhibitor particles or precursors selectively dispersed within the second polymer material. These multiphase polymer compositions may be used for other applications, such as self-cleaning, self-healing, or flame-retardant coatings.

The liquid may be a lubricant. For example, the liquid may be selected from fluorinated oils, siloxanes, petroleum-derived oils, mineral oil, or plant-derived oils. The liquid may consist of or include water. The liquid may be an electrolyte. For example, the liquid may be selected from poly(ethylene glycol), ionic liquids, dimethyl carbonate, diethyl carbonate, or methyl ethyl dicarbonate.
