Abstract: The present invention provides a battery electrode comprising an active battery material enclosed in the pores of a conductive nanoporous scaffold. The pores in the scaffold constrain the dimensions for the active battery material and inhibit sintering, which results in better cycling stability, longer battery lifetime, and greater power through less agglomeration. Additionally, the scaffold forms electrically conducting pathways to the active battery nanoparticles that are dispersed. In some variations, a battery electrode of the invention includes an electrically conductive scaffold material with pores having at least one length dimension selected from about 0.5 nm to about 100 nm, and an oxide material contained within the pores, wherein the oxide material is electrochemically active.

Abstract: This invention provides a novel battery structure that, in some variations, utilizes a mixed lithium-ion and electron conductor as part of the separator. This layer is non-porous, conducting only lithium ions during operation, and may be structurally free-standing. Alternatively, the layer can be used as a battery electrode in a lithium-ion battery, wherein on the side not exposed to battery electrolyte, a chemical compound is used to regenerate the discharged electrode. This battery structure overcomes critical shortcomings of current lithium-sulfur, lithium-air, and lithium-ion batteries.

Abstract: A thermomagnetic sensor, measurement system and a method of measuring temperature employ a thermomagnetic probe to measure temperature of a device using a thermomagnetic effect. The thermomagnetic sensor includes a plurality of coils configured to provide a mutual inductance measurement between a selected pair of coils of the plurality and the thermomagnetic probe between the selected pair. The thermomagnetic probe includes a ferromagnetic material having a temperature-dependent magnetic permeability determined from the mutual inductance measurement. A predetermined relationship between the temperature-dependent magnetic permeability and temperature in a range between a maximum magnetic permeability value and a Curie temperature provides a measurement of a temperature local to the thermomagnetic probe.

Abstract: A new battery structure as disclosed allows convective flow of electrolyte through three-dimensional structured electrodes. Hierarchical battery structure design enables three-dimensional metal structures with fluid transport capabilities. Some variations provide a lithium-ion battery system with convective electrolyte flow, comprising: a positive electrode comprising a lithium-containing electrode material and a conductive network with hollow liquid-transport conduits; a negative electrode comprising a lithium-containing electrode material in the conductive network; a separator that electronically isolates the positive and negative electrodes; and a liquid electrolyte contained within the hollow liquid-transport conduits of the conductive network. The hollow liquid-transport conduits serve as structural members, and the walls of these conduits serve as current collectors. The conductive networks may include a micro-lattice structure with a cellular material formed of hollow tubes. Performance and thermal management of lithium-ion batteries (and other types of batteries) can be improved.

Abstract: A lithium-ion battery structure with a third electrode as reference electrode is disclosed. The reference electrode may be fabricated from lithium metal, lithiated carbon, or a variety of other lithium-containing electrode materials. A porous current collector allows permeation of reference lithium ions from the reference electrode to the cathode or anode, enabling voltage monitoring under actual operation of a lithium-ion battery. The reference electrode therefore does not need to be spatially between the battery anode and cathode, thus avoiding a shielding effect. The battery structure includes an external reference circuit to dynamically display the anode and cathode voltage. The battery structure can result in improved battery monitoring, enhanced battery safety, and extended battery life.

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 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.
