摘要： This invention provides methods for dynamic estimation of the open-circuit voltage of a battery. In some embodiments, an impulse response is calculated using a matrix-based algorithm or a recursive algorithm. Then, a current response is calculated by convolving the impulse response with the measured current. The open-circuit voltage of the battery is derived by subtracting the current response from the measured voltage. Using the principles disclosed to estimate OCV, a lithium-ion battery may be managed with a battery-state estimator that allows accurate and timely estimation of the state of charge, the charge and the discharge power capabilities, and the state of health of the battery. These methods are able to accept various exciting signals, are stable and robust against noises, even when diffusion is a limiting kinetic factor in the battery.

摘要： The present invention provides impulse-response-based algorithms for high-speed characterization of electrochemical systems (e.g., batteries) with good accuracy. In some variations, a method for dynamic characterization of an electrochemical system comprises selecting an electrochemical system to be characterized; sensing the measured current to or from said electrochemical system; sensing the measured voltage across said electrochemical system; sensing or calculating the time derivatives of the measured current and voltage; and calculating an impulse response using a recursive or matrix-based algorithm (as disclosed herein), wherein said impulse response characterizes said electrochemical system within a selected sampling window. The algorithms are robust, incorporating noise-reduction techniques, and are suitable for real applications under various operating conditions. These algorithms, and the apparatus and systems to implement them, are able to accept various exciting signals to provide dynamic characterization of various states of the electrochemical system.

摘要： A thermomagnetic sensor includes a thermomagnetic probe that includes a ferromagnetic material having a temperature-dependent magnetic permeability characterized by a maximum magnetic permeability value at a temperature below a Curie temperature of the ferromagnetic material. The thermomagnetic sensor further includes an alternating magnetic field source to produce an alternating magnetic field in a vicinity of the thermomagnetic probe to facilitate a measurement of the temperature-dependent magnetic permeability as function of temperature remotely using a thermomagnetic effect. A predetermined relationship between the temperature-dependent magnetic permeability and temperature in a range between the maximum magnetic permeability value and the Curie temperature provides a measurement of a temperature local to the thermomagnetic probe. A battery-temperature measurement system includes the thermomagnetic probe in a battery, a magnetic field coil to apply the alternating magnetic field, and a magnetic permeability measurement apparatus to measure the temperature-dependent magnetic permeability.

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 mesoporous, nanocrystalline, metal oxide construct particularly suited for capacitive energy storage that has an architecture with short diffusion path lengths and large surface areas and a method for production are provided. Energy density is substantially increased without compromising the capacitive charge storage kinetics and electrode demonstrates long term cycling stability. Charge storage devices with electrodes using the construct can use three different charge storage mechanisms immersed in an electrolyte: (1) cations can be stored in a thin double layer at the electrode/electrolyte interface (non-faradaic mechanism); (2) cations can interact with the bulk of an electroactive material which then undergoes a redox reaction or phase change, as in conventional batteries (faradaic mechanism); or (3) cations can electrochemically adsorb onto the surface of a material through charge transfer processes (faradaic mechanism).
