    摘要： A method of determining and predicting a state of a rechargeable battery device in real time involves measuring a current and a voltage of the rechargeable battery in real time, inputting the measured current and voltage into an algorithm, and applying the algorithm to determine the state of the rechargeable battery. The algorithm includes a first mathematical model based on a direct solution of at least one differential equation characterizing an equivalent RC circuit of the battery as a function of time. The first model generates a plurality of parameters that are usable to determine the state of the battery. The algorithm further includes a second mathematical model configured to regress the parameters over time, and a third mathematical model configured to estimate the state of the battery.

    摘要： The current thickness limitations of battery electrodes are addressed. An electrode includes an electrically conductive porous foam layer, an energy-storage material in contact with the porous foam layer, and electrically conductive porous foam protrusions extending from the porous foam layer into the energy-storage material. The energy-storage material is not contained within the pores of the foam layer or the foam protrusions. These electrodes allow lithium ions (and other metal ions, if desired) to diffuse deeper into a thick energy-storage material layer, compared to conventional planar electrodes. In particular methods, fluidic foam precursors can be templated in a mold, followed by conversion into a solid conductive foam that includes the electrically conductive porous foam protrusions. The result is batteries with surprisingly high energy densities.

    摘要： A regenerative fuel cell is provided by the present invention. In the methods and systems described herein, a source of fuel is partially oxidized to release protons and electrons, without total oxidation to carbon monoxide or carbon dioxide. The partially oxidized fuel can be regenerated, by reduction, when the fuel cell is reversed. Other variations of the invention provide a convenient system for hydrogen storage, including steps for both release and recapture of hydrogen.

    摘要： An electronic device, such as a thin-film transistor, includes a substrate and a dielectric layer formed from a dielectric composition. The dielectric composition comprises a dielectric material and a low surface tension additive. The low surface tension additive allows for the formation of a thin, smooth dielectric layer with fewer pinholes and enhanced device yield. In particular embodiments, the dielectric material comprises a lower-k dielectric material and a higher-k dielectric material. When deposited, the lower-k dielectric material and the higher-k dielectric material form separate phases.
